Teaching kids to invest
Custodial accounts, age-appropriate investing, and the best first investments for young people.
Most adults are afraid of investing because nobody taught them when the stakes were low. A 12-year-old with $200 in a custodial account who watches their money go up 15% and then drop 10% learns more about market behavior in six months than most adults learn in a decade of reading articles. The goal isn't to make your kid rich — it's to make investing feel normal before they have real money to manage.
Custodial accounts: UTMA vs. UGMA
- UGMA (Uniform Gifts to Minors Act) — allows adults to open a brokerage account on behalf of a minor. Can hold stocks, bonds, mutual funds, and cash.
- UTMA (Uniform Transfers to Minors Act) — same thing but broader. Can also hold real estate, patents, and other assets. Available in most states.
- Both transfer full ownership to the child at the age of majority (18 or 21 depending on the state). You cannot take the money back.
- The first $1,300 of investment income is tax-free. The next $1,300 is taxed at the child's rate. Above that, it's taxed at the parent's rate (the 'kiddie tax').
- UGMA/UTMA assets count heavily against financial aid eligibility. If college aid is a concern, consider a 529 plan instead for education-earmarked money.
Age-appropriate investing lessons
- Ages 6–10: Let them pick a company they know (Apple, Disney, Nike). Buy one share. Check the price together monthly. The goal is ownership and curiosity, not returns.
- Ages 11–14: Introduce the concept of index funds. Compare their single stock pick to a total market fund over the same period. Talk about diversification in concrete terms.
- Ages 15–17: Open a custodial Roth IRA if they have earned income. Discuss the difference between speculation and investing. Let them experience a market downturn without selling.
The best first investments
- A total stock market index fund (VTI, SWTSX, FSKAX) — broad diversification, rock-bottom fees, no decisions to make.
- An S&P 500 index fund (VOO, SWPPX, FXAIX) — slightly more concentrated in large companies but equally simple.
- A single share of a company they use daily — not because it's optimal, but because ownership of something tangible creates engagement.
What small money becomes: the motivation chart
Show a kid this chart with their own age on it. Fifty dollars a month — allowance-and-birthday-money scale — becomes real wealth given a multi-decade runway, and every year of delay costs thousands off the far end. The point of showing it isn't to pressure a 10-year-old into maximizing returns; it's to make time itself visible. Kids intuitively believe money grows by adding more. The chart shows the truer thing: money grows by starting sooner, and they are currently holding the one advantage no adult can buy back.
Setting up the account: a 20-minute project
- 1Pick the account type
Custodial brokerage (UTMA/UGMA) for general money; custodial Roth IRA if the kid has earned income; 529 if the money is really for college. For a teaching account, UTMA with a small balance is the usual choice.
- 2Open it at a major low-cost brokerage
Fidelity, Schwab, and Vanguard all offer custodial accounts with no minimums and no fees. The parent controls it; the kid watches it.
- 3Fund it with an amount you can ignore
$100-500 is plenty. This is tuition for a behavior class, not a college fund — keep the serious money in accounts built for serious money.
- 4Buy together, out loud
Let the kid place the order with you: pick the fund or share, preview the cost, press buy. Ownership begins at the moment of purchase, not at the first gain.
- 5Schedule the check-in
Once a month, five minutes, same day. Frequent enough to stay real, rare enough to teach that investors don't stare at prices.
The conversations each market moment unlocks
- The first gain: 'You didn't do anything and you made $6. That's the whole idea — your money worked while you were at school.' Plant the ownership frame early.
- The first drop: the most valuable moment in the entire project. 'It's down $11. We're not selling — we own the same amount of the company as yesterday. Drops are the price of the long-term returns.'
- The dividend: 'The company shared its profit with its owners, and you're one of them.' Turn on reinvestment together and explain that the dividend just bought more shares that will pay more dividends.
- The hot tip from a friend: don't forbid it — run the numbers together and, if the sandbox money allows, let them try a small position. A $30 loss on a hyped stock at 13 is a bargain vaccine.
- The boring year: when nothing happens for months, say so. 'This is what investing looks like almost all the time.' Normalizing the boredom is half the training.
Expect, and welcome, the uncomfortable questions — they're evidence the lessons are landing. 'Why don't we just buy whatever goes up the most?' opens the door to survivorship bias and why last year's winner is not a strategy. 'Is this gambling?' deserves a precise answer: gambling is a negative-sum bet on randomness; owning the market is buying a slice of every company's future profits, which have grown for a century because humans keep making things people want. And the hardest one — 'why is my friend's dad rich from crypto?' — earns the truest answer in finance: some people win lotteries too, and you never hear from the ones who didn't. A parent who answers plainly instead of dodging builds something rarer than investment knowledge: a kid who keeps asking them about money at 17, 22, and 30.
The finish line for this whole project isn't a portfolio balance — it's a teenager who has personally owned assets through a gain, a drop, a dividend, and a long stretch of nothing, and who found all four unremarkable. That kid arrives at their first real paycheck already knowing what to do with it, immune to both the fear that keeps their peers out of the market and the gambling instinct that wrecks the ones who do get in. Two hundred dollars and five minutes a month is a cheap price for that.
