Custodial Roth IRA: What a Teen's Paycheck Becomes by 65

One $1,000 Roth deposit at 14 could grow to $129,100 by 65 at a 10% average return. At 45, just $6,700. How a custodial Roth IRA works and how to open one.

A custodial Roth IRA is a Roth IRA opened in a minor's name and run by an adult until the child comes of age. The only real requirement is that the kid earned money. A paycheck, babysitting, mowing lawns. For 2026 the teen can put in whatever they earned, up to $7,500, and every dollar of growth after that can come out tax free in retirement. The math is the reason to care. One $1,000 contribution made at 14 is worth $129,100 at 65 at the stock market's long-run average return. The same $1,000 made at 45 is worth $6,700. Same dollar, same account, nineteen times the result, and the only difference is when it went in.

In July 2026, 21.3 million Americans aged 16 to 24 had a job, according to the Bureau of Labor Statistics. Most of those paychecks go to the same places yours did at that age. Almost nobody tells a 16-year-old that a slice of their summer money can go into one of the most tax-advantaged accounts available to regular people, decades before their friends even hear the word "Roth."

This is the whole thing, priced in dollars.

TL;DR

A custodial Roth IRA lets a minor with earned income invest up to the lesser of $7,500 or what they earned in 2026, with an adult running the account until the child takes control, usually at 18 or 21 and as late as 25 in some states. Contributions can be withdrawn at any time without tax or penalty. At a 10% return, the S&P 500's long-run average since 1928, $2,500 a year from ages 15 to 18 becomes $1,023,300 at 65. An adult who puts in $2,500 every year from 25 to 64 ends with $1,217,100, after contributing ten times as much. Retirement accounts are not counted as assets on the FAFSA.

What a Custodial Roth IRA Actually Is

Strip the name down and it is two ideas stacked on top of each other.

A Roth IRA is a retirement account you fund with money that has already been taxed. In exchange, the growth is never taxed again if you follow the rules for taking it out. A custodial account is how a minor gets one. Kids cannot sign brokerage contracts, so an adult, usually a parent, opens the account in the child's name and acts as custodian. The money legally belongs to the child from day one. The adult just makes the decisions until the child is old enough to take over.

That handover age depends on your state. Fidelity describes it as happening "typically between age 18 and 25, depending on the state." Schwab puts the usual age of termination at 18 or 21, and up to 25 in some states.

There is no minimum age. IRS Publication 590-A answers the question of whether you can be too young to contribute with one line: "No. You can be any age." What there is, instead, is an income rule. And that rule is where most families get stuck.

The One Rule: The Money Has to Be Earned

A custodial Roth IRA runs on one requirement. The child needs compensation, which the IRS defines as wages, salaries, tips and net earnings from self-employment. The annual contribution cannot be more than $7,500 "or if less, your taxable compensation." A teen who earned $1,800 this year can put in up to $1,800. A teen who earned $12,000 can put in the full $7,500.

What counts surprises people in both directions. Babysitting and lawn money is the one people miss. The IRS says it directly: "Students who do odd jobs over the summer to make extra cash are self-employed. This include jobs like baby-sitting or lawn care." Self-employed income counts for a Roth, but it comes with a catch. Once net self-employment earnings reach $400 in a year, the teen owes self-employment tax of 15.3%, which is Social Security plus Medicare, and has to file Schedule SE. Keep a simple log: dates, who paid, how much. If the IRS ever asks where the contribution limit came from, that log is the answer.

Here is how the common sources of teen money sort out.

Money the teen receivedCounts toward the limit?
Paycheck from a restaurant, store, camp or pool jobYes
Babysitting or lawn care moneyYes. The IRS treats these students as self-employed
Wages from a parent's business for real workYes, at a reasonable wage for the work done
AllowanceNo. It is not pay for work
Birthday money and giftsNo
Investment incomeNo

Income tax is a different story. For 2026, a dependent's standard deduction is the greater of $1,350 or earned income plus $450, capped at the regular $16,100, per Revenue Procedure 2025-32. In plain terms, a teen whose only income is a paycheck can earn up to $16,100 in wages before owing a cent of federal income tax. That is exactly why the Roth fits so well. The money goes in at a 0% federal income tax rate and can come out at a 0% rate. It is hard to find a better deal anywhere in the tax code.

Parents who own a business have one more door. When a sole proprietorship run by a parent pays a child under 18 for real work, those wages are not subject to Social Security and Medicare taxes. The work has to be real and the pay has to be reasonable. Paying a 12-year-old $7,500 to "answer emails" is the kind of thing that ends badly in an audit.

Why a Roth, and Not a Savings Account

A teenager with a summer job has three obvious places to put money. A checking account, a savings account, or a Roth. The first two feel safe. They are not, at least not over fifty years, because the dollar is designed to lose value.

Cash in a bank earns a little interest, but the purchasing power of the dollar drops almost every year. We walked through the numbers in Your Savings Account Is Losing Money. Over a teenager's working life, that slow leak does more damage than any single bad year in the stock market. Money that sits still gets smaller.

A Roth IRA is not an investment by itself. It is a wrapper, a tax-protected box you put investments into. Inside the box the teen can hold stock index funds, which own small pieces of hundreds of real companies. That is where the long-run return in the math below comes from.

The Roth part is what makes it special for a teen. There are two main flavors of IRA. A traditional IRA gives you a tax break now and taxes you later. A Roth skips the break now and never taxes you again on qualified withdrawals. For an adult in a high tax bracket, that choice is a genuine trade-off. For a teenager who owes no income tax, there is nothing to trade. The break a traditional IRA offers is worth zero to someone already paying zero. The Roth's tax-free future is worth a lot.

Money the teen needs soon, for a car or first-semester books, belongs in savings. Money the teen will not need for decades belongs in the box. Most teens have some of each, and the split is a good first conversation about what money is for.

What One $1,000 Contribution Is Worth at 65

Here is the part school never showed most of us, because it only works if someone starts a kid young.

A dollar invested at 14 has 51 years to compound before 65. A dollar invested at 45 has 20. Compounding does not reward those extra years in a straight line. It rewards them exponentially, because every year's growth starts growing too. What Is Compound Interest? walks through the mechanics. This chart shows the result for one single deposit.

One $1,000 Deposit, Valued at 65

The same $1,000, put into a Roth IRA once and never touched. The only thing that changes is the age it went in. Amber bars are the teen years.

$0$35k$70k$105k$140kAge 14$129,100Age 16$106,700Age 18$88,200Age 20$72,900Age 25$45,300Age 30$28,100Age 35$17,400Age 40$10,800Age 45$6,700

Untaught model. $1,000 contributed once, valued at 65 at a 10% annual return, the S&P 500 long-run average since 1928 per NYU Stern. Rounded to the nearest $100. Returns are not guaranteed and no single year looks like the average.

Look at the jump from 18 to 45. The same $1,000 goes from $88,200 to $6,700. The years a teen spends in a custodial account are worth more per dollar than any decade that follows.

Every number on this page uses the same model, so you can rerun it yourself. Each contribution grows at 10% a year until 65, and the value is the contribution times 1.10 raised to the number of years left. Ten percent is the S&P 500's long-run average. According to NYU Stern's Aswath Damodaran, $100 invested in the S&P 500 at the start of 1928 grew to $1,157,598.95 by the end of 2025, a geometric average of 10.02% a year with dividends reinvested, according to his downloadable dataset. After inflation, the same data puts that return at 6.78%. We show the 10% figure because that is what an account statement will say. The 6.78% figure is what the money actually buys, and it matters. At that rate the same $1,000 made at 14 is worth about $28,400 in today's dollars, not $129,100. Still about 28 times what went in.

The Grid: When the Teen Starts and How Much Goes In

One deposit makes the point. Real families contribute every year the teen works. The grid below assumes the teen puts the same amount in every year from the starting age through 18, then never adds another dollar.

Start age$1,000 a year$2,500 a year
14$538,500$1,346,100
15$409,300$1,023,300
16$291,900$729,800
17$185,200$463,000
18$88,200$220,500

Value at 65, at a 10% annual return, rounded to the nearest $100. The teen contributes every year from the start age through 18, then stops. Starting at 14 means five years of contributions, starting at 18 means one.

The full $7,500 a year is left off the grid on purpose. It would mean the teen earned at least $7,500 every year, which is a serious job for a 14-year-old. For the record, $7,500 a year from 14 through 18 comes out to $4,038,400 at 65. The middle column is the honest one. $2,500 is one summer of part-time work, roughly 20 hours a week for ten weeks at $12.50 an hour. Four of those summers, starting at 15, put $10,000 into the account and are worth $1,023,300 at 65 on paper.

Run the same grid at the 6.78% after-inflation return and the numbers shrink, but the shape does not. $2,500 a year from 15 to 18 becomes about $241,500 in today's buying power. That is nearly a quarter of a million dollars of real purchasing power bought with $10,000 of summer money. Nobody gets that deal at 40.

The other thing the grid shows is how fast the advantage disappears. At $1,000 a year, starting at 18 instead of 14 cuts the result from $538,500 to $88,200. The four skipped deposits were only $4,000 of principal, but they were the four with the most time to grow, and together they account for essentially all of that $450,300 gap. The early years are the expensive ones to skip.

Four Teen Years vs. Forty Adult Years

The classic objection is that a teenager's few thousand dollars cannot matter much against a whole working career. So we ran it. Two people, the same $2,500 a year, the same 10% return. The teen contributes at 15, 16, 17 and 18, then stops forever. The adult starts at 25 and contributes every single year until 64.

$10,000 In at 15 to 18 vs. $100,000 In at 25 to 64

The teen puts in $10,000 and stops at 18. The adult puts in $100,000, every year from 25 to 64. Same $2,500 a year, same 10% return.

$0$250k$500k$750k$1M$1.25MAge 15Age 25Age 35Age 45Age 55Age 65$1,217,100adult, $100k in$1,023,300teen, $10k inAt 40 the teen is still ahead, $94,400 to $87,400

Untaught model. $2,500 a year, valued at a 10% annual return, the S&P 500 long-run average since 1928 per NYU Stern, rounded to the nearest $100. At a 7% return the adult finishes further ahead, $534,000 to $266,900. Returns are not guaranteed.

The teen puts in $10,000. The adult puts in $100,000. The teen is still ahead at 40, $94,400 to $87,400. The adult does not pass them until 44. At 65 the adult finishes with $1,217,100 and the teen with $1,023,300.

Read that again. Forty years of disciplined saving, ten times the money, and the adult finishes only 19% ahead of a kid who quit at 18.

In fairness, the result depends on the return. At a 7% rate the adult finishes further ahead, $534,000 to $266,900, because lower returns give each extra contribution more weight relative to time. The lesson holds either way. The teen's four deposits are doing work the adult has to pay for with thirty-six extra years of contributions. And the teen does not have to choose. Nothing stops them from contributing at 15 and at 25. That person beats both.

This is the same pattern the Start Tomorrow Trap describes for adults. Waiting is never neutral. It is a cost you pay later, with interest.

How to Open a Custodial Roth IRA

Opening one online is quick. You need the parent's details, the child's Social Security number and date of birth, and a bank account to fund it from.

  1. Confirm the income. Add up what the teen earned this year from paychecks and self-employment. That total, up to $7,500, is the ceiling.
  2. Pick a brokerage. Fidelity lists its Roth IRA for Kids at $0 minimum and $0 account fees. Schwab offers a custodial Roth IRA and, in its Roth IRA for kids guide, says these accounts generally have no minimum balance or opening fees. Vanguard offers a custodial Roth, which it also calls a minor IRA.
  3. Open it in the child's name with you as custodian.

  1. Fund it. The contribution limit is set by what the teen earned. Many parents fund part or all of it as a gift or a match, the way an employer matches a 401(k). A 50% match is a powerful lesson in itself.
  2. Invest it. Cash sitting inside a Roth earns far less than stocks over decades. Choose a broad, low-cost stock index fund, such as an S&P 500 index fund.
  3. Keep the records. Save W-2s, pay stubs or the babysitting log for every year you contribute.

The last step is the one people skip, and it is the one that protects everything else.

Getting Money Out Before 65

Parents worry about locking a kid's money away until retirement. A Roth is more flexible than that, because the rules treat the money you put in differently from what it earns.

The contributions themselves can come out at any time, tax free and penalty free. IRS Publication 590-B spells out the order. Withdrawals come from regular contributions first, and a return of those contributions is not included in income. The earnings are the part the rules protect.

Earnings come out tax free only once the account has been open five years and one of the conditions in the table below applies. That five-year clock starts with the first tax year a contribution was made. A teen who opens the account at 15 has satisfied it by 20, which makes the first-home exception, up to $10,000 of earnings over a lifetime, a real option in their twenties.

What comes outIncome tax?10% early penalty?
The teen's own contributions, any timeNoNo
Earnings after 59½, account open 5+ yearsNoNo
Earnings for a first home, up to $10,000 lifetime, account open 5+ yearsNoNo
Earnings used for college costsYesNo
Earnings for anything else before 59½YesYes

College is where families get nervous, so here is the verified answer. The 2026-27 federal student aid handbook says the value of retirement plans, including non-education IRAs, "is not counted as an asset." A balance sitting in a Roth does not reduce aid. The catch is the second half of the sentence: "distributions do count as income." The FAFSA looks at income from two years earlier, so a withdrawal in the early college years can shrink a later year's aid package. The cleanest plan is to leave the Roth alone and pay for school from other sources.

This flexibility is a safety valve, not a strategy. Every dollar pulled out early stops compounding for good. The grid above is only true if the money stays in.

One habit makes all of this easier later. Keep your own running total of what went in, year by year and net of anything already taken out, next to the pay records. Because contributions come out first and come out tax free, that single number tells you how much of the account can be touched without tax or penalty. It is also the record to have ready if a withdrawal is ever questioned.

Custodial Roth vs. the New Trump Account

Since July 4, 2026, families have been able to contribute to a second kind of account with a similar pitch. Trump Accounts were created in 2025 legislation, and the IRS guidance explains the basics. Children born from January 1, 2025 through December 31, 2028 can receive a $1,000 federal pilot contribution. By March 31, 2026, the IRS reported more than 4 million children signed up, with more than 1 million claiming the $1,000.

They solve different problems. The comparison below uses only what the IRS has published.

FeatureCustodial Roth IRATrump Account
Needs earned income?YesNo
2026 contribution limit$7,500 or earned income, whichever is less$5,000 a year, which includes up to $2,500 from an employer
Free government moneyNone$1,000 for children born 2025 through 2028
What it can holdWhat your brokerage offersFunds tracking the S&P 500 or another index of mostly American stocks
Access before adulthoodContributions can come out any timeNo withdrawals before January 1 of the year the child turns 18
Tax treatment laterQualified withdrawals are tax freeGenerally treated as a traditional IRA, so earnings are taxed when withdrawn

For a baby or a young child with no job, the Trump Account is the only option of the two, and if the child was born 2025 through 2028, the $1,000 seed is free money worth claiming. For a teenager with a paycheck, the custodial Roth wins on the part that matters most over fifty years. Its growth comes out tax free. A family with an eligible child and a working teen can use both.

Where Bitcoin Fits, and Where It Doesn't

Untaught teaches that small, steady amounts moved into assets that hold value beat money left to lose it. For many adults we cover here, that has meant dollar-cost averaging into Bitcoin. So can a custodial Roth hold Bitcoin?

Partly, and it depends on the broker. On January 10, 2024, the SEC approved the listing and trading of spot bitcoin exchange-traded products, funds that hold Bitcoin and trade like a stock. Fidelity says its crypto funds can be held in brokerage, trust and IRA accounts, but buying one requires a Designated Investments Agreement and an account investment objective of "Most Aggressive." We could not find any brokerage page confirming that a custodial account for a minor can buy them. Ask your broker directly before assuming it can.

Even where it is allowed, we think the order matters. SEC Chair Gary Gensler's statement on the approval calls Bitcoin "primarily a speculative, volatile asset." It has dropped by more than 75% from peak to bottom at least three times since 2013, according to iShares. A teenager's Roth is the one account with a fifty-year runway and no taxes on the way out. Its core job is to capture the broad market's long-run return, and a low-cost stock index fund does that.

That does not make Bitcoin wrong for a young person. It makes it a separate habit. A teen can fund the Roth from their paycheck and, once they are old enough to hold their own account, buy small amounts of Bitcoin on the side, the way our $20 a week math describes. Two tools. Neither one has to be all or nothing.

The system counted on nobody teaching your kid this.

No spam. Just a heads up when we launch.

The Weekend Plan

If your teen worked this summer, you can have this done by Sunday night.

  • Saturday morning: gather the pay stubs or write down the babysitting and yard-work income. Total it.
  • Saturday afternoon: open the account at whichever brokerage you already use, or pick Fidelity, Schwab or Vanguard.
  • Sunday: fund it, even if it is $200, and buy one broad index fund. Then sit down with your teen and show them the $1,000-by-age chart in this article.

The deposit matters. The conversation matters more. Most of us learned how this works years after the cheapest years were already gone.

The single most valuable financial asset a teenager has is not their paycheck. It is the fifty years in front of it. A custodial Roth IRA is the simplest account built to turn those years into money that is never taxed again.
