Teaching kids about money, from piggy bank to first paycheck.

Children learn about money long before anyone sits them down to explain it. They notice the tap of a card at the checkout, the tone of voice when a bill arrives, the conversations that stop when they walk into the room. By the time they’re old enough for a “money talk,” they’ve already absorbed a set of beliefs about it, mostly from watching you.

That’s not a reason for guilt. It’s a reason to be deliberate. The good news is that the most effective ways to teach children about money are simple, cheap and, for the most part, fun.

Earlier than you think

In 2013, researchers David Whitebread and Sue Bingham at the University of Cambridge reviewed the evidence for the UK’s Money Advice Service and concluded that the building blocks of later money behavior are typically in place by around age seven. By then, most children can plan ahead, hold off on a decision, and understand that money is limited and gets exchanged for things.

Seven is not a deadline; people change their money habits at every age. And the same review found something parents should take to heart: explaining financial facts to young children does little on its own. What shapes them is practice and example, handling real money and watching how the adults around them handle it.

So you don’t need to wait until a child understands interest rates to start. You need to give them some money and let them use it.

Housel was writing about adults, but it explains why childhood matters so much. Whatever money looked like in your house growing up became, for years, what money looks like. Children will generalize from yours in exactly the same way.

What the marshmallow test really showed

You’ve probably heard of the Stanford marshmallow experiment. Starting in the late 1960s, psychologist Walter Mischel offered preschoolers one treat now or two if they could wait. Follow-up studies found that children who waited longer went on to better outcomes years later, and the study became shorthand for the idea that self-control is destiny.

A larger replication in 2018, by Tyler Watts, Greg Duncan and Haonan Quan, told a more nuanced story. Once they accounted for family background, the link between waiting and later success shrank considerably. Part of what the original test measured was whether a child had reason to trust that the second marshmallow would really come.

For parents, that’s the more useful lesson. Patience is learned, and it’s learned in environments where waiting reliably pays off. When you promise that saving will lead to the toy, make sure it does.

Ages 3 to 5: money is real and finite

• Use cash when you can. A card makes money invisible; coins and notes make it concrete. Let them hand over the money at a shop and get the change.
• Talk out loud about choices. “We could get this, or save for the zoo on Saturday. Which do you think?” shows that spending on one thing means not spending on another.
• Try a clear jar. Seeing coins pile up is more motivating than a closed piggy bank.
• Practice waiting. Small, short goals, a sticker book in two weeks, teach that waiting works.

Ages 6 to 10: an allowance and three jars

This is the age when an allowance becomes useful, and the most common question is whether to tie it to chores. Ron Lieber, the New York Times personal finance columnist, argues in The Opposite of Spoiled that you shouldn’t. An allowance is a teaching tool, a small budget to practice with. Chores are what everyone in a family does because they live there.

Tie the two together, and a child who doesn’t need money this week can simply opt out of emptying the dishwasher.

A common approach, and one Lieber favors, is three jars: spend, save and give. A share of every allowance or gift goes into each. The spend jar is theirs to use as they like, including on things you think are a waste. The save jar is for bigger goals. The give jar is for a cause they choose. It builds, in miniature, the same structure grown-up budgets use.

How much? A rough rule some families use is about a dollar a week per year of age, but the right amount depends on what they’re expected to pay for. The bigger the allowance, the more of their own spending it should cover.

Ages 11 to 14: bigger budgets, real trade-offs

• Hand over a real budget. Give them the clothing or back-to-school money for the season and let them decide how to spend it. They’ll learn fast that one designer item means fewer everything else.
• Introduce interest. Some parents pay “parent interest” on savings, say 5% a month on what’s in the save jar. It’s a generous rate, and that’s the point: it makes compounding visible and exciting.
• Open a savings account together, and let them see statements and the interest arrive.
• Talk about advertising and in-game purchases. Show them how apps and influencers are designed to make them spend.
• Share more of the family picture. Not your salary if you don’t want to, but what the groceries cost this week, why you chose one holiday over another, or how you save for things.

Ages 15 to 18: preparing for independence

• Encourage a first job, and walk through the first paycheck together. The gap between hourly pay and take-home pay is a lesson in taxes they won’t forget.
• Give them a debit card linked to an account you can see, and let them run it.
• Explain credit before they get offers. How cards work, what a 24% APR means in dollars, and why a credit score will affect the rent and the car loan.
• Talk honestly about college costs and loans. Look at net price calculators together, and make the borrowing decisions with them, not for them.
• Show them investing. If they have earned income, a custodial Roth IRA lets them start compounding decades early.

A growing number of US states, now more than half, require a personal finance course before high school graduation. That helps, but it’s no substitute for having handled real money, with real consequences, while still living at home.

Accounts that give them a head start

• 529 plans. Tax-advantaged savings for education; growth is tax-free if spent on qualified costs. Many states add a state income tax deduction for contributions, and grandparents can contribute too. If your child doesn’t need it all, up to $35,000 over their lifetime can be rolled into a Roth IRA in their name, once the account has been open 15 years, within the yearly IRA limit.
• Custodial Roth IRAs. Available once a child has earned income, from babysitting, a summer job or work in a family business, and contributions can’t exceed what they earned. Money invested at 16 has a very long time to grow.
• Custodial brokerage accounts (UGMA/UTMA). Flexible, but the money legally becomes the child’s at 18 or 21, depending on your state, and it counts more heavily in financial aid calculations.
• Trump Accounts. New in 2026, these are tax-advantaged investment accounts for children under 18. US citizen children born from 2025 through 2028 get a one-time $1,000 contribution from the Treasury. Family and others can add up to $5,000 a year combined, with no earned income required, and employers can chip in up to $2,500 of that. You enroll through the IRS (Form 4547) or trumpaccounts.gov.

Most planners put your own retirement ahead of a child’s college fund. It feels backwards, but children can borrow for school, and nobody lends for retirement. Being financially secure yourself is one of the best gifts you can give them.

What they learn from watching you

Children learn from what parents do more than what they say. A few habits that teach more than any lesson:

• Talk about money calmly and without shame, including mistakes you’ve made and what you learned.
• Let them see you wait for things, compare prices, and choose not to buy.
• Include them in the fun decisions, like planning a trip on a budget.
• Avoid “we can’t afford it” as a reflex. “That’s not what we’ve chosen to spend on” is usually more accurate, and it teaches that money is about choices.
• Give together, and let them choose where.

A family tool

Foundation is built for households. You can set Save up goals for the things the whole family is saving for, from a trip to a college fund, and track 529 and other accounts alongside everything else. The shared view is a good starting point for age-appropriate conversations with older kids: here’s what’s coming in, here’s what we’ve planned, here’s what’s left to spend.
