There's an awful lot of negativity here, but as someone who's 55 and has earned a good wage since I was 17, I really wish I had taken investing more seriously from the very beginning. While I knew of compound interest, I really didn't understand it until like a decade ago. If I'd started putting 5% of my money into a target retirement plan from 17, I'd be retired now. As it is I'm not doing badly, but I really wish I'd started earlier.

So I say: Good on you.

Somewhat related: I just got my son set up with a custodial account and put his "kid retirement" plan into it, and let him pick a couple stocks to put some money into, and put the majority of it into target retirement and a few stocks and EFTs, so he can get some ideas of how they perform, make it a little fun with picking things he's into, and also follow ups and downs of the market, all of which I think is good education.

Investing for retirement at 17 is a bad idea! At 17 you should still be thinking about investing in education - the right education investment today will pay back far more than any other monitory investment. There are of course bad education investments, and some are not willing to study even more (or not able to pass a good education course), in that case retirement might be the best investment you can make, but it should not be your first choice.

A different reply said they waited until 26 to start - that is probably about the right time to start saving for retirement. Maybe a little late, but close enough. Before about that age you are still getting started and so you have little spare cash. You need to pay off school loans (if you took any). You need to save for down payment on a house, and buy a lot of those will last a lifetime household items everyone needs. You should be thinking about marriage and saving for it (even if you don't get legally married most people will live with someone else and should be planning on how to make that life work).

Most important: you don't know how long you will live. Save for the future, but not everything - you have no guarantee you will live to tomorrow - if you are under 60 odds are strongly in favor of it, but people die young all the time. You should have a little play money as well in your budget. Go climb Mt Fuji while your body is young and healthy enough to do so (I picked a random activity here, you should decide what you care about, not rush to Japan)

If you start investing a small amount at age 17 you can build the habit and increase totals later.

Saying "I'll do it later when it is rational" often translates to "I won't do it (for a long time)". Which is not rational

This is true of most money behaviors! My mom taught me the same thing about giving.

And even today, knowing way more about personal finance than I did at the start of my working life, I'm still amazed at how blocking out money in the budget astronomically increases your chances that that money actually goes to the thing you want.

They mean don't wait till you're rich to start giving charity. Just give what you can when you can. Many people tell themselves they are great people because of all the money they'd give away just as soon as they are rich enough to do it but die without giving anything.

More or less: yup.

The great thing about saying "give 10%" is how well it scales.

simianparrot 1 day ago||
Except it doesn’t. If you’re poor, 10% directly impacts your life negatively. It means less (or lesser quality) food. It means less money set aside for yourself in the case you need it — and you will.

10% for middle class is fine. That’s just one less night out.

People should not give to charity if they themselves are likely to be dependent on charity.

Brendinooo 1 day ago|||
I could get into virtue ethics or religion but I know this is Hacker News, so maybe I can frame it like this:

Telling people to wait until they're financially stable before giving risks creating a dynamic where people never start. The person who says "I'll give when I can afford it" at $30k is likely to say the same thing at $100k, because the scarcity mindset scales with income.

Small-scale giving early on helps build the identity and habits of someone who contributes to their community rather than just consuming from it.

And arguably there are network effects formed from generosity of time/money that can bring long-term benefits as well. It's a spicier idea, but I could even suggest that giving helps you see money as a tool rather than as security itself.

mathgeek 1 day ago||||
This comment perfectly illustrates the mindset folks are talking about. "I'll give when it doesn't hurt me so much" is another form of "I'll give when I have more." It doesn't make the person "bad" or any such thing for not giving, but you won't convince folks to not give by saying "but what about you, don't you want nicer food/clothes/etc."
bluGill 1 day ago||
Most people do think they have less than they really do - which is to say there are families living on less income than they are thus proving it is possible with some luxury quality of life compromises. However that doesn't destroy the point that there are people at or near the bottom who shouldn't be giving.

Probably something like this: https://www.youtube.com/watch?v=6ayPuijerjQ tldr; have your kids split their money into three separate "jars": Spend (can be freely spent), Save (this jar generates interest from the money in it, they also have to wait some time to access the money if they want to spend them) and Give (for charity).

Yes. You can make it a 2% contribution at 17 then add another 2% each year, until you hit say 24% at 29 then keep it there.

Then the habit is set up and you just log in to whatever and up the number.

I think it's actually a bad thing to think about money early on. Because it adds a layer of responsibility which I think takes away from simply enjoying life and focusing on what you might be truly passionate about.

One of the things I hate about my 30s is that I'm focused on money now and it feels like I'm not living the life that I want. It just feels like I'm preparing for death.

Which I'm not saying isn't the sensible thing to do, there's just something inherently managerial about it which doesn't seem intuitive to living a meaningful life.

The earliest years of your earning life contribute overwhelmingly more to your final retirement figure than your later years. Anyone lucky enough to have a job in their teens that gives them disposable income after each paycheck really, really, really should be saving and investing. Like OP, if I was more serious about investing in my early years, I would be retired by now.

One can lead a meaningful, enjoyable life while also considering their finances.

> The earliest years of your earning life contribute overwhelmingly more to your final retirement figure than your later years.

for most the amount we earn before about 25 is so little that even everything saved at the best return is insignifitant inretirement. at 25 a small percentage of your income saved becomes meaningful, but you are likely to earn enough more at 35 that the amount you can save then totals to more

dottjt 2 days ago|||
> One can lead a meaningful, enjoyable life while also considering their finances.

This is where I disagree. I think there's a certain amount of naivety required to pursue meaningful things. There's so much in life that makes no financial sense that creates meaning. The moment you start having to think sensibly from a financial perspective, is when so many of these things no longer make sense.

Once you're plugged into the system there's almost no turning back.

I get the sentiment, but it implies the opposite of your conclusion.

Since so many things make no sense from a financial point of view, the only sensible strategy is to break free of the financial constraints as soon as possible. Money cannot buy you happiness, but it can buy you the freedom to pursue it.

Retire early to give yourself the best cushion (and best possible chance) to pursue meaningful things, without the everlooming sword of making ends meet. The added benefit of life experience to filter out pursuits that only look meaningful on the surface, is a nice side-effect of this strategy.

So I think the reason why this doesn't make sense (in my mind) is because in a state of retirement i.e. financial independence, you're still just as conscious of money as you were when you were accumulating wealth. You still need to manage money no different to when you were accumulating, it's just now you're not earning.

To me the freedom I'm referring to is similar to that of childhood - where you're not worried/concerned about "the system". You're just doing your own thing in your own world. That kind of purity no amount of money can resolve, even in an early retirement scenario.

The other issue is that a lot of stuff only makes sense when you're younger. Like it's a lot difficult for example to become a travelling musician or even to travel etc.

Now of course, early retirement provides it's own kind of freedom. But I would say that it's not equivalent to the kind of "freedom" that I'm referring to, which is basically being carefree.

The only ways you can live as an adult unconcerned about the system is 1. if you actually have a substantial financial backstop (trust fund, wealthy parents, etc.) and just pretend you don't, or 2. if you don't have a financial backstop, at which point "doing your own thing in the world" just means being a vagrant, drifter or bum.

Oh, the FIRE community. If you trained yourself to live looking at the money you need to save to retire, your brain will most likely be wired to that behavior, and breaking free from that will be utterly difficult. On top of that, people with the FIRE mindset have probably by default already a strong (innate? taught?) bias towards enjoying optimizing their life and making it the end goal.

> Oh, the FIRE community.

I think you may be confused, I'm not part of the FIRE community. I'm only taking the statement that "doing meaningful things is not financially sensible" to its logical conclusion, not endorsing any position.

> If you trained yourself to live looking at the money you need to save to retire, your brain will most likely be wired to that behavior, and breaking free from that will be utterly difficult. On top of that, people with the FIRE mindset have probably by default already a strong (innate? taught?) bias towards enjoying optimizing their life and making it the end goal.

So many assumptions and claims without any supporting evidence:

- "FIRE people" train themselves to live looking at money only.

- This wires their brain to that behaviour (left unclear what this actually means in terms of concrete behaviour).

- Breaking free from this behaviour is difficult.

- People with this mindset have a bias towards enjoying optimizing their life, to the point this is their end goal.

- (Implied) This makes their life some combination of sad/bad/meaningless.

I don't really want to even argue against this because the burden of proof for providing any supporting evidence is yours, not mine. I'm not particularly interested in constructing some overarching psychoanalytic theories for a large category of people who I've never even interacted with, but you do you.

FAANG job at 22. Save up 25k a year for 4 years, that is 100k. You'll already retire at 56 with over 1.5M in the bank. It isn't perfect but it is a lot better than what most people do.

Really all you need to do as a programmer is max out 401k and maybe throw another 10k a year into savings on top of that.

I worked at MSFT for a decade and I would have retired at 40 if I hadn't spent 3 years trying to run a startup after my time at Microsoft.

This includes international travel every year, and 2 domestic vacations.

bluGill 1 day ago||
> You'll already retire at 56 with over 1.5M in the bank

That 1.5M isn't inflation adjusted. If there is 0 inflation between now and when you die 1.5M is plenty. However the more inflation there is between now and when you die the more money you will need, the later you need to retire, or the less spending money you have. (of course we need to asking how things like social security fits into your plans as well, but this is already complex enough).

If you 22 and used to a FAANG income even with saving $25k/year every year you need more than 3M to retire retire without losing quality of life (even though most of that is luxury).

Are you willing to live on less, or will you discover with your free time you want to spend more money (hobby supplies? Now you have time to travel - maybe first class). I can't answer this question for you, but you need to think about it. Worse, your answer is likely to change over time.

The root comment was talking about investing 5% of their earnings. If you're making any kind of income at 17 (which admittedly is not everybody) then learning to save+invest a small portion of that can have incredible positive snowball effects beyond the compounding itself.

I can't imagine a scenario where at 55 years old, you would miss the 5% of your summer income you invested back in high school. But I can totally see a scenario where investing those 5% led you to increasing it to 10% in college, 20% on your first job, and being financially independent way before you hit the age of 55.

"I can't imagine a scenario where at 55 years old, you would miss the 5% of your summer income you invested back in high school."

If those 5% were the question of whether to go with the group on a adventure together or not - and you end up alone at 55 years and not invited .. you might have rather invested different back then. But on the other hand I don't think those 5% of earnings with 17 make a difference later.

The only real difference they can make, if they made you start a habit of saving income for important purchases. (But not really fore retirement at that age. But each to his own)

I think this really comes down to how a teenager is wired and life circumstances. Some of us made all our close friends in college and dont even live near our hometowns anymore. My high school friendships are all “dead” so to speak.

I think if a teenager is the social type, or they have a positive (non-toxic) friend group, then absolutely - spend the money! It’s an investment in your friends that may or more not pay off.

But some teenagers don’t have much in common with their peers, are bullied in high school, or just want to move on to the “real world” and graduate already. For those kids, invest!

"or just want to move on to the “real world” and graduate already. For those kids, invest!"

In general sure, it really depends .. so invest in what? It can mean many things, like also saving for the drivers licence/first car to make that move away into a nicer worlds with better opportunities.

lurking_swe 2 days ago||
absolutely! It’s always a good idea to write down your life goals and major planned expenses. Then you can prioritize them as needed.

That usually helps answer questions like “if i invest X% of each paycheck into an S&P500 index fund, and put the remainder toward saving for my 1st car, i’ll have money for the car by date Y.”

And this skill translates to adult life really well. I find myself doing just that a couple times a year! Of course for some teenagers investing a substantial amount is simply not realistic…not every family is middle class after all.

One important reminder: inflation is no joke these days. I’d only recommend a savings account to a teenager for short term goals. Even if they are poor.

Most 17 year olds have very low income and education goals. They will miss that 5% in a retirement fund because they are forced to take a student loan to cover that.

As with many times when we use the word "should" (and you've used it a lot), the perspective you're sharing is deeply influenced by your own cultural background and might not apply to many people reading.

A few examples: school loans, considering a house purchase to be a sound investment, purchasing once-in-a-lifetime household items, saving for a wedding (from the age of 17!?) or marriage (not sure what you even mean by that if you don't mean the wedding itself?).

bluGill 2 days ago|||
The details matter and are personal I agree.

Even if a house isn't right for you, you still need to save for the deposit on an apartment. You still need to buy furnishings for your apartment. You won't even know if a house is right for you until you are mid 20s to 30, so it is probably best to save for a house and if you decide at 30 it isn't right for you roll that money into retirement savings (if a house isn't right for you that means you need more retirement savings)

Relationships - even if you don't have a wedding or kids - come at the time you have those starting to get out on your own expenses. You will need to figure those out.

sebastiennight 2 days ago|||
You just replaced "buying a house" with "buying an apartment", proving my point about cultural bias :-)

I meant, for many people (especially young ones), taking that same deposit to purchase an investment property (which could be a house or apartment, but has a tenant who lives there rather than being for oneself) can be a better deal than buying for themselves.

In the end, buying a place to live in is very much an emotional choice, which is totally valid. But in some locales and for some lifestyles, being a landlord who pays rent elsewhere can be a better financial decision.

Especially in the current climate you should be fully aware that it's significantly more risky to start investing today vs 10 yrs ago.

(Riskier doesn't mean it's necessarily a bad idea. It should just be a conscious decision under the acknowledgement that the upward trajectory is not certain.

First, I don't think this absolute statement is true; I think you need to look at it from the alternatives perspective. If not investing then what? bury gold? spend it all?

Second, are we at a much riskier time than past history, both short & long term? I made significant contributions in 2014, saw 30%+ wiped out within 6 months and seen it all come back and more with the power of long timeframes.

Third, investment can take a lot of forms, not just today's hot tech stocks. I won't get into it beyond the standard think long term and avoid leverage, which seems to be completely inline with start early; start now.

Your money has to go somewhere or it will rot to inflation. If you're ultrabearish on stocks, snap up bonds. If you're bearish on stocks and bonds alike, snap up gold. Either way, bare minimum of what to do with your money long term is to preserve its value across inflation.

But really I would recommend nonetheless staying the course with investment advice on a stocks/bonds balance relative to your age. Increasingly, the economy distributes not through labour but through capital and holding stocks is essential even with their inherent risks. Even in light of that CNN article about meme stock and crypto investors having the last laugh over the past decade, indices of ordinary large-cap stocks bring you exposure to these things.

> Your money has to go somewhere or it will rot to inflation.

Inflation is mainly created by this act of "putting your money somewhere". For most people, this "somewhere" means loans. Money is being loaned out to people, spent, deposited back into the bank, and loaned out again, on and on it goes until $1,000 turns into $100,000 in circulation, not a cent of it real until all loans are paid back.

carllerche 2 days ago|||
You are very confidently incorrect. So incorrect, it is hard to even start correcting you.

* Inflation is not caused by "putting your money somewhere" What on earth. * At a high level, inflation is caused by either "too much money chasing too few goods" and/or the cost of producing the goods rising. Money supply can increase without causing inflation if the supply of goods can also increase. In short, the supply of money can increase without causing inflation if productivity rises to match it. * Most people do not "put money" in loans what are you even talking about there? * Bank loans do not automatically increase the supply of money. When a loan is taken out, it is (mostly) deposited to another bank, resulting in a net-zero change in money. Increasing the supply of money requires the federal reserve to take steps.

matheusmoreira 2 days ago||
> In short, the supply of money can increase without causing inflation if productivity rises to match it.

You're actually agreeing with me. Money supply must be backed up by real wealth and production.

That's not how things work in current times. We have nearly zero interest rates, and currencies are backed up by literally nothing.

> Most people do not "put money" in loans what are you even talking about there?

Fractional reserve banking. Banks loan out the cash you deposit. They "efficiently allocate" the money in their custody.

> Inflation is not caused by "putting your money somewhere" What on earth.

It absolutely is. Banks can easily turn thousands of dollars into hundreds of thousands of dollars by repeatedly loaning out the exact same dollars numerous times.

It's some kind of society wide financial call stack. Too many defaults and everything starts unwinding.

> Bank loans do not automatically increase the supply of money.

Obviously they do.

Imagine you deposit $100 at your bank. It takes your $100 and loans out $90 of it to someone else. There are now $190 dollars in circulation.

Whoever took the loan goes off and spends it. Eventually it gets deposited back into a bank. Then the bank loans out $81 out of that $90. There are now $271 dollars in circulation.

And it keeps going.

You can inflate bitcoin via this algorithm.

> When a loan is taken out, it is (mostly) deposited to another bank

Irrelevant. Banks form interconnected systems. They all settle debts and accounts with each other.

> Increasing the supply of money requires the federal reserve to take steps.

The physical supply of money is irrelevant. It contributes only a small fraction of the circulating money supply. Money is numbers in bank databases now. They could run the money printers 24/7 and they'd never even come close to catching up to the inflation caused by banks.

I've made a similar deal with my kids: Around 7 years ago I set up a "kid retirement" plan for them, where they couldn't touch the money until they were 18, but any money they put in I would match, and I'd also give them 10% APY with monthly compounding. My daughter aged out of it a couple years ago, she got something in the $100 range. Her brother still has a 18 months left, and I just recently rolled his over into the custodial account, he's got over a grand in there currently.

My daughter I just recently set up a ROTH for her and told her I'd match anything she puts into it, and stressed she should put something into it now from her savings, and then put some of her paycheck into it, anything is better than nothing. So far she's declined the free money. I'm going to set one up for my son, once he's at the point of having an income to justify it. She's very smart, but in some ways she's very stupid.

That young you should be investing in a 527 education account not a ROTH retirement account. Education is a much better ROI when you are young than anything else. As you get older the value of education decreases. In generally the cross over is sometime in your early/mid 20s (Could be as young as 16 if you don't do well in school, or as old as 35 for things like medical doctor)

If you don't live in the US you will have different options, but the idea still applies

I'm doing a 529 as well as wanting to set up the ROTH Note that you can also just take money from your other investments, deposit it into a 529, and then immediately pay yourself back for educational expenses you've paid for off the 529.

My kids have some 529 buffer, and we are paying for my daughter's school right now (though she's paid us back for the class she got an F in). My son, it's not clear that the typical school track is going to be the right thing for him, but we also have a 529 for him that I've been contributing to.

There are a lot of it depends. If you are going to be a retail worker all your life there is no reason to go to college. A music degree has questionable value on its own, but many people get them understanding that "any degree" is needed for some good jobs and those that find those do well enough (your generals and non-major electives are important). The school matters - Harvard is expensive but the networking can be worth it if you network well in school. State schools tend to be a lot cheaper than private or out of state as well, and generally pretty good. Scholarships enter in as well. Degrees like Engineering or Medical doctor tend to have a much better ROI long term, but only if you pick the right one and pass.

But you need to make your own decisions. For some your best ROI is dropping out of school at 16 - but for the vast majority more school will be worth it.

I don't know the first thing about student loans (interest rates, amortization periods). I never had one. I just search-engined 2025 federal student loan rates and I'm blown away by the interest rates. It looks like avoiding student loans at all costs is the way to go.

I wonder if spending a few years working (especially if your parents are able to continue to house you and pay for health insurance) and contributing to a 529 plan might meaningfully decrease the overall cost, albeit at the "penalty" of starting college later in life (at, say, 22 instead of 18).

I take that even a little farther. Whatever my kids make (up to the Roth limit), I give them money to put into a Roth IRA [and they can keep what they earned].

That maximizes what they (as teenagers) can put into retirement accounts, their tax rate is 0% now, and though it doesn't teach them the deferred gratification aspect, it gets their retirement savings started.

We can talk about the deferred gratification aspect in other ways and/or later, but I'd rather they get 40-60 years of tax-free growth.

Is your daughter feasibly going to make “real money” in the future? I personally look back on working a job in college as a waste of time and attempting to save money then as a waste of effort. Should have just taken more debt, the amount I did take turned out to be trivial to pay off and double or triple wouldn’t have been that bad. I feel like there are two worlds employment wise, and some advice leaks between them which ends up being maladaptive in its new environment.

OP, enabling: - deposits (and withdrawals) - a matching logic (which we can do manually I guess, by doubling the deposit amount) - and correct calculation of compounding (if I had $100 for 11 months and add $100 in december, I shouldn't see the value compound $200 for the whole year)

You say that now but as a young person with a decent income and no family or many responsibilities it's hard to even know where to start.

And I'm not even talking about what to invest in, I'm already confused at which platform/bank/whatever to do it through. The "meta", if you will.

Maybe an important detail, I'm from Switzerland, perhaps it's easier in the US with things like Vanguard.

coldpie 2 days ago|||
Don't know about Switzerland, but most US brokers offer some kind of "target retirement date" fund, which automatically shifts from higher-risk assets to lower-risk as you approach retirement. VFIFX is one from Vanguard, for example. Pick one you like (just ask a coworker what they use, if you pick a big-name brokerage it really doesn't matter which one), shove your extra cash into it regularly, and forget about it. Then cross your fingers the market isn't actively crashing when you plan to retire (this is unlikely, but it does happen a couple times per century).

If you start to get into truly high wealth amounts (USD$500K+) you might consider hiring a wealth advisor, who can probably do better even after accounting for their fees.

If you have doubts about the long-term __existence__ of the market, then investing in the first place necessitates "timing the market" since you'll need to determine when to sell before the panic sell-off which inevitably comes before the global minimum is reached.

Mind you, I'm not talking about figuring out whether or not to "hodl" through local minima. I'm talking about rolling into a different store of value (e.g., cattle, crops, ammunition) before the whole thing goes up in smoke.

All the choices you have to make can be very daunting. I was very lucky to have a colleague at work who gave a talk at the right time in my life with some plausibly right choices.

In the UK I started out using https://www.charles-stanley-direct.co.uk/ and later moved to https://www.ii.co.uk/. I initially invested in https://www.vanguardinvestor.co.uk/investments/vanguard-life... which is a fund which is available on a bunch of platforms. These days I recommend https://www.vanguardinvestor.co.uk/ to some people as an easy and low fee way of getting started with Vanguard funds in the UK.

I don't know what the best trading platform options are in Switzerland - it looks like all of the ones I'm familiar with are not relevant to you.

The key thing is you want to minimise two types of fees: * Platform fees * Product fees

For example Charles Stanley Direct charge 0.3% platform fees, and https://www.vanguardinvestor.co.uk/ charges 0.15% platform fees.

Vanguard LifeStrategy® 100% Equity Fund charges 0.22%.

The bottom line is that there are lots of good choices, and the main thing is to make a choice and get started. You can always optimise/improve your choices later.

Are you saving for retirement or buying property? Then start filling your 3rd pillar (Säule 3a) first because of the tax cut. Ideally in a low cost provider (viac/finpension), but the bank you already have probably has an offer too. It might be a bit more expensive than viac, but still much better than not investing. Stay away from 3rd pillar at insurance companies, they might be hard to cancel. Do yourself a favor and do this just for the tax cut.

If you max out the 3a, you can start of thinking investing elsewhere. IBKR is the cheapest to buy a US domiciled world ETF. But the UX is not super easy and you will have to fill all transactions manually in the tax report.

Neon with investments is another option I can recommend if you prefer a swiss company and a simple user interface. Fees are low if you set up a savings plan and pick one of the 0% ETFs

Banks don't typically charge any fees for a self-directed account that holds primarily ETFs, beyond maybe a small trade fee or account fee(?) - which we would never pay in North America. Active management of either your account or the products you hold is where they stick it to you.

My bank also charges a trade fee which I think is bullshit, but at least it's a major bank. It's like $10 so doesn't matter all that much, not sure how much it would be for Switzerland, but you could just buy the stocks in larger batches if trades are expensive.
a96 1 day ago|||
$10 may not feel like much, but it's the proportional costs that you have to figure out.

If that's e.g. for a monthly $1000 investment, it means 1% of your savings is lost in fees each time. That'll be 1% that's not going into savings. If you end up with a million by some time, that small fee will have cost you 1% of that, which is $10k.

"It's just a cup of coffee" -> "that's a 10 000$ cup of coffee". But if you only save 200 a month, that 5% is 200k you've lost by the end.

One percent is often considered a reasonable cost ratio, but it's definitely worth considering what the real numbers are for a given option.

onli 2 days ago|||
With the amount people usually trade $10 is a huge percentage. When you factor that in with the missed compound interest of that money you usually lose tens of thousands of dollars until retirement, likely more.

There is no need for a big bank here, in Europe. If one of those regulated companies goes bankrupt the etf is still yours and transferable to a different institution.

- Your bank's platform will cost an arm and a leg; Interactive Brokers or Degiro are both available in Switzerland and you will save so much on fees (especially if you only buy and hold ETFs of which Degiro offers many with 0% fees) that it's the equivalent of faster returns on your money.

- There are many "getting started" guides available, I found Mister Money Mustache the most straightforward to my liking, but you're golden as long as you understand a couple of basics: 1. investing a high% of your income is more important than chasing returns (you seem to be there already), 2. don't trade, just buy the whole market (you mentioned Vanguard, they offer a "total market" ETF), 3. look for the lowest fees as long as you hold title to your shares (IB and Degiro do this ; eToro does not so if they sink, you're SOL), 4. don't time the market, just buy now and sit on it as it grows

For the plattforms, that also blocked me for a while. But it is easy now. You just get one account at a platform that offers a free broker account and supports buying the etf you want without extra fees.

Typical options in Europe: Trade Republic, scalable, Consors Bank.

Then the usual: Around 10K where you can access it directly, a small amount in an investment with percentage (scalable and trade republic both offer that, limit there is or was 50k), rest in one broad ETF like one that follows the FTSE all world (vanguard or invesco offer that, one is bigger, the other asks for less fees).

No affiliation, and I dont know whether being outside of the EU changes things. And yes, there is the risk that we are in a huge bubble now and it popping would at first significantly lower the money put into the etf. But you certainly do have access to vanguard etc.

Financial literacy is a gift, and absolutely omitted from standard education, which is unfortunate.

That said, I don't think knowledge of investment gets you very far if your job pays subsistence wages.

I don't know what you mean by that. They teach compound interest in every school. Basic economics too. Anything more advanced is going to be lost on most kids, because that's most adults' level of financial literacy too.

The problem is many kids don't have much money to save or invest. Or if they do, real banks kinda suck when you only have a kid amount of money ("Here's the 0.2% interest on your $37 balance"). So they can't apply what they learned. An app like this, backed by the Bank of Mom and Dad, is great for practice.

While I certainly had the _concept_ of compound interest taught to me at some abstract mathematical level, the application to real life practical financial scenarios was definitely not done [1]. Economics as a whole was an optional subject.

I think schools and curriculums could do a whole lot better in representing this important facet of life. More broadly, I often feel that "applying all that math you've learned to real things" is a subject that could be taught.

[1] Seriously, having applied math questions like "Johnny earns X per year, with a cost of living of Y. Assuming inflation of Z and average yearly returns of R, what percentage should he be putting away, starting at age 25, so that at age 50 he essentially gets the equivalent of his own salary each month?" would likely cause some lightbulbs to go off in the kids' heads.

It's way easier to update the tail end of knowledge you have and practices you've learnt than to start from scratch when you have no time.

Likewise, if the only stuff we could teach in grade school was stuff that would never become outdated, then we wouldn't even be able to teach more than the highest level of recent history, math foundations, super basic geology and physics, which is a pathetically low bar. Things change, it's the way it is, we should have a higher standard.

Kids won't otherwise get early exposure to learning how to start a business unless their parents did so, or investing unless their parents did, which means they probably had a surplus of resources at home and the cycle of a widening class divide continues.

The most powerful type of compound interest is early exposure to anything; an idea, a sport, money, business, computers, art. If your parents did it, you're off to a great start, but if they didn't, you're automatically set back at least a decade if not two for any of those, and public school should aim to smooth out those bumps.

Most of my family is farmers or missionaries, and I bet those groups are less likely than most to own stocks.

Also, 'owning stocks' vs 'investing' feels different to me. My brother will go all in on tesla for one year, and then pull out and just sit there until he has another somewhat-random impulse. Likewise, my dad used to put all his money into some index funds for the 30 days leading up to Christmas, because 'the government always makes the stocks go up during the holidays, to keep everybody happy'. They count as 'owning stocks' (at least sometimes), but I don't feel they count as 'investing'.

Illnesses and accidents are exactly the things you need savings for, and aren't really relevant here because they don't prevent you from saving until and after they happen.

As far as I know in the US your employer provides health insurance?

array_key_first 2 days ago|||
Some jobs provide healthcare, many don't.

Many people here, if they are not educated, are forced to work manual labor jobs. Those jobs will always work you under full-time, so they don't have to give you insurance. Usually that means you have to work another job.

People who haven't lived that life just don't get. It just doesn't click in your head.

You can work 60 hours a week and just barely make rent and food. Not only can you do it, I think most people are. And there's nothing you can do. There is no higher paying job waiting for you somewhere, because you don't have a college degree.

How're you gonna get a college degree when you work 60 hours a week? Hm? You're not. You're stuck. Your best shot, really, is to work up through management. That's why you'll see people working at the same restaurant for 20 years.

Oh. No. Not in most jobs. Many jobs do provide some health care.

If you are working many jobs in the US you get no health care. You have to pay for it yourself. Even jobs that provide it you still need to pay for it. The employer basically pays a portion of the insurance bill. Good employers pay a lot, bad employers pay none.

Then you have deductibles. The amount you have to pay out of pocket every year before insurance does anything. If you have a ten thousand dollar deductible, insurance only kicks in at $10,001 and beyond.

You're saying that $500-600 (the amount you claim 50% of people have saved up, if it's the median) covers 3 months of expenses?

throw-qqqqq 2 days ago||
I mean no offense, but your understanding of a median seems flawed. The median is the number/point that separates the upper half from the lower half - it is not what 50% has.

The math does add up. There is no contradiction in your parent’s post.

sebastiennight 2 days ago||
I'm not sure I catch your explanation, so let's try with some simple numbers and you'll tell me where I'm wrong.

I have a family of 10 people. These people have, respectively,

$0 ; $0 ; $1 ; $5 ; $49 ; $51 ; $190 ; $8,000 ; $150,000 and $1,000,000.

What's the median amount of savings in this group?

And what amount would complete the sentence : "50% of people have ..."?

throw-qqqqq 2 days ago||
The median of those ten numbers is 50.

If the count of observations is even, it is usually the arithmetic mean of the two mid-points, so (49+51)/2 in this case.

The median does not have to be in the finite set of values.

Maybe Wikipedia can explain better than I can: https://en.wikipedia.org/wiki/Median

sebastiennight 2 days ago||
You didn't answer my second question. Yes the median in my example is $50. Thus it would be accurate to say "50% of people in that sample have $50 (or $51)". But not anything further than that middle point.

Back to the original post:

I'm assuming that "three months of expenses" would be roughly $6,000.

The parent post had the median at $500.

1. Given the sheer number of adult Americans (hundreds of millions of observed data points), wouldn't you say it's quite likely that the two mid-points are very close to each other (eg $499.97 and $500.02)? But definitely not (-$5,500) in debt for one mid-point individual vs $6,000 in savings for the next individual (which comes out to $500 in median and "top half has $6k")?

2. In the first scenario (almost continuous curve at the midway point), how likely do you think it is that somewhere right after that $500 mid-point, there is a huge discontinuous jump to $6,000 to accomodate the idea that the rough top half of observed savers has "3 months of expenses" saved?

3. Is there any other scenario I'm not foreseeing, that can reconcile: "the median is $500" with "the top 50% have $6,000+ in savings"?

throw-qqqqq 1 day ago||
> You didn't answer my second question

I purposely didn’t because strictly that is not a median. Stupid example: median of 1,2,3 is 2 and 67% >= 2 here. We do agree that as N grows, the difference shrinks (to the point of no meaningful difference).

My point was that mathematically there is no contradiction. Let’s say half the population has $200 monthly expenses (3mo is then $600 saved), the median is $600 and it checks out.

That is a stupid assumption though - because who has such low expenses.

> I'm assuming that "three months of expenses" would be roughly $6,000

You then assume that we must be talking about the upper half, but that isn’t given.

We have to make SOME assumptions though, since the statement is underspecified: the OP didn’t specify what 3 months expenses means. It is unlikely that 50% of the US population have the EXACT same expenses, so I assumed an “on average” was missing somewhere which further relaxes the constraints.

I objected to your statement that the math doesn’t check out. There are many ways it could check out.

We came at this with different assumptions. I don’t think we fundamentally disagree and I didn’t mean to bicker.

davsti4 1 day ago|||
One word answer - security.

Any website you visit could have been compromised and serving malicious content. Upon first visit to a website, I block all connections to domains not in the address bar, then go back in and add rules to allow connections as needed. It doesn't address malicious activity by the site directly, like a server compromise, but does limit non-addressed connections, including ones to local addresses.

For example, a compromise of .google.com which leveraged assets/code from .googleusercontent.com wouldn't initially be able to run, unless I added a rule to allow the connection. Likewise, a compromise of *.discord.com that made a connection to localhost:8983, then tried to send that data to someserver.ru would get blocked and logged. Where this can't protect me is if the server sends the mined data back to itself, then forwards that data on using its own connection.

Ad networks sell to anyone. Malicious content can be injected almost anywhere. Its happened before; it'll happen again. This web browsing hygiene has protected me enough times for me to make it my standard practice.

Still, if a 10 year old had started investing 10% in the market in 1920 and stuck through it during the depression, even with no income coming in at the time, they would have done handsomely through the recovery and into old age. In fact, a middle aged person who had been investing until 1929 would have not been fully cleaned out, and that money would have recovered its value by 1943.

I run a "Bank of Dad", tracked in a spreadsheet for my kids. They can choose to "invest" their money with me or not. To make investing meaningful for them, I pay 10% interest per month, up to a $50 balance.

To avoid bankrupting myself—and to encourage them to get a real investment account when the time comes—the rate drops as the balance increases, similar to progressive tax brackets. By the time they get to $1000 balance, the annualized rate works out to ~6%, and after that it drops fast enough that it's essentially free for me to operate.

Overall, it's been quite successful. Now whenever the kids get money, they invest it immediately. And they often delay or forego spending so that they can get more interest the next month. They haven't turned into complete misers, but it has encourage a mentality of thinking about saving, and I think the concept of interest has landed quite well. I think things really started to click for them around age 8 or 9.

For me, the ethics of investing is a bit more profound. I see stock market investment and share holding to be one of the main drivers of civilisations obsession with endless consumption and growth. To me those things are damaging to our minds and our planet. This is just doing the same retarded shit we’ve been doing since the end of the war. Personally I feel like we need to turn a corner now; ease-off this obsession with accumulating as much money as possible for ourselves and focus on our communities, our families, living in balance with nature, and securing a healthy future together with new values and goals that last. Investing into the stock market is like the opposite of this. Just my opinion.

Where can I get 15% annualized returns, please?

(I'm told to no longer bet on even averaging 7% annually, over decades, on US stock indexes.)

15% yield would be a hell of an arbitrage opportunity if you could get a sensible loan to go along with that.

11% may be the safest bond you have access to, but that doesn't make it _safe_ in absolute terms.

So, bonds basically all tend to converge on the same risk adjusted yield. If you're seeing yields that look like this, the market believes the currency will slip or there's repayment risk (relative to USD bonds that are in the 4.75% range.)

Imagine you have a scenario where inflation is 0 in currency A and 10% in currency B. Would you rather have a 2% bond in currency A or a 9% bond in currency B? This is why Euro bonds go negative sometimes, when USD interest rates were very low and the Euro was deflationary relative to the dollar, it could push rates even further lower.

Look, you do you, but rest assured that you don't get 11% for no reason.

I wrote an article (it's in Spanish) in which I took data from the central bank since 1990 and created a tool to simulate various scenarios. The tool includes a column showing the average interest rates on central bank-backed investments. Maybe you might find it interesting. https://roberdam.com/jubilar.html

It's not an inherent feature, but they steer it in such a way so, no, there isn't (at least not for long), unless someone would make a good case for it at some point in the future

The interesting question would be what their currency, where this 11% is offered, typically loses year-on-year

When I started working at 24, a friend of mine (a few years older than me) asked me if our company had a 401(K) and what was the match.

I was confused. What's this gobbledygook? So I asked around and got him the answers, and he responded with: max out your 401(K). Just do it. And do not ever think about taking money out of it.

So I followed his advice. At that time, the ~$5500 cut in paycheck (my gross was around $35K, IIRC) stung a little. I was single, footloose and fancyfree, and those extra few hundred dollars a month would have been fun to have. But I stuck to his advice.

Today, almost 30 years later, thanks to that, I have a nice nest egg and don't have to worry about retirement (modulo catastrophic illnesses, of course).

So recently my friends' kids started working, and I gave them the same advice: Max out your 401(K), pick a Vanguard Target Retirement fund, and forget about it. If your place offers a "Mega Back Door" option, use it to the fullest extent possible. And if your company has a HDHCP, put funds in your HSA too.

We have a lot of avenues to save these days. Make full use of them.

> We have a lot of avenues to save these days.

Consider investing your time, not just your money. In other words, do careful research, start a business, then put your labor into offering a product or service that fills a need, instead of simply working for someone else. If you fail, you'll still learn a lot for another try. And if you succeed, the payoff can be much larger and faster than anything else you might attempt.

The reality is you'll probably lose a ton of money, then get another job.

I used a lot of the money I could have 'saved for retirement' on a house instead. Given how fast housing prices have risen and the compounding issue of the cost of rents, I'm not sure I'm too far behind. If you look at REITs, which combine the value of housing appreciation with increased values of rents, they are beating stocks in general over the period I've been working.

You might actually be worse off saving for retirement, at early career stages. Of course, some will point out retirement savings are tax protected, but so are modest capital gains on primary residence.

> You might actually be worse off saving for retirement, at early career stages.

A very well-diversified, international fund usually performs at 8% annually which is far more than you would get holding REITs (or worse, properties themselves). What you invest for (e.g. education, retirement, projects) is irrelevant as long as your time horizon allows for crash recoveries (measured in decades at worst and months at best).

REIT is largely a reflection of property appreciation plus rents, which is the opportunity cost of not owning your own property. The link I posted was showing an 8+% return once accounting for both over the a 20 year period that doesn't even include the recent COVID era price explosions.

If I'm not mistaken, they usually pay at least 3% dividend which is added to your salary. ETFs don't trigger any tax as long as you don't sell. And I didn't check but REITs probably have higher annual fees.

I was using REITs as a proxy for the value and opportunity cost of buying your housing rather than investing in a retirement account. If you actually buy REITs this breaks down because REIT capital gains are taxable, while residence capital gains on a primary residence of modest value are not.

It was not my intent to convey you should buy REITs instead of a place to live.

After early career this breaks down though, because the tax advantage are only good for primary residence modest value homes, it's not a strategy that can be continually employed.

> 8% annually

Historically, yes - but the last 5 year average has been ~14% (I guess it's like ~9% if you're adjusting for inflation). I think 10% is a bit of a better number these days.

That's not to say I couldn't be eating my words when the market crashes tomorrow, however.
