How Much at Age 18? Trump Account Growth

The question every parent wants answered: How much will my child actually have at age 18?

It depends on three things — the federal deposit, how much you contribute each month, and stock market returns. Let's break down the numbers across realistic scenarios so you can plan with confidence.

Starting Point: The $1,000 Federal Deposit

Children born between January 1, 2025 and December 31, 2028 receive a one-time $1,000 deposit from the federal government. This money goes directly into the Trump Account and gets invested in S&P 500 or broad U.S. equity index funds.

Even if a family contributes nothing else, that deposit grows for 18 years through compound returns. Here is what it could become:

Scenario 1: The $1,000 Deposit Alone

Not every family can contribute extra. That is okay. The federal deposit still works for you. At a historical average of 8% returns, $1,000 grows to about $4,000 over 18 years. At 10%, it reaches roughly $5,600.

That may not sound life-changing. But remember — it cost the family nothing. And at 18, it converts to a traditional IRA that can keep growing for decades.

Scenario 2: $100/Month — The Starter Plan

One hundred dollars a month is about $3.33 per day. Add the $1,000 deposit, and at 8% returns, the account could reach roughly $52,000 by age 18.

That is enough for a meaningful chunk of college tuition, a solid start on a home down payment, or a powerful retirement head start.

Scenario 3: $250/Month — The Sweet Spot

This is where the numbers get exciting. Contributing $250 per month (which equals $3,000/year, well within the $5,000 annual cap) could grow to over $100,000 at 8% returns.

That is six figures before your child even finishes high school. The power of compound growth is real.

Scenario 4: $416/Month — Maxing Out

The maximum annual contribution is $5,000, which works out to about $416 per month. At 8% returns, a maxed-out account with the $1,000 deposit could reach roughly $207,000 by age 18.

At 10% returns, it could top $260,000. This is a life-changing amount of money for an 18-year-old.

Why 18 Years of Compounding Is So Powerful

Compound growth means your returns earn their own returns. In the early years, growth feels slow. By year 10, it accelerates. By year 15-18, the growth curve gets steep.

This is why starting early matters so much. Every month of delay reduces the total. A child who starts at birth gets 18 full years of compounding. A child who starts at age 5 gets only 13 years — and the final number can be tens of thousands of dollars less.

What Happens at Age 18?

At age 18, the Trump Account converts to a traditional IRA. Your child takes full control. They can:

• Keep it invested and let it grow for retirement
• Withdraw funds for any purpose (subject to income tax and potential early withdrawal penalties)
• Convert to a Roth IRA for future tax-free growth
• Use the first-time homebuyer exception for up to $10,000 penalty-free
