Trump Account Calculator: How Much Could Your Child’s Roth Be Worth?
How much could a Trump Account grow if you started funding it today? We built an interactive calculator to help you find out.
The Trump Account (officially a Section 530A account) launches July 5, 2026, and allows families to contribute up to $5,000 per year per child into a tax-deferred account — no earned income required. The real power isn’t the account itself; it’s the backdoor Roth conversion you can execute once the child turns 18.
Our calculator models the full lifecycle: contributions from birth (or any starting age), tax-deferred growth, a multi-year Roth conversion in the child’s low-tax years, and decades of tax-free compounding afterward. Adjust the sliders to match your family’s situation.

What the Numbers Show
Here are a few scenarios to give you a feel for the math:
Newborn, $5,000/year for 18 years, 7% return: By age 60, the account grows to roughly $3.3 million tax-free in a Roth IRA. Total family outlay: $90,000. Estimated conversion tax (spread over 4 years in the 12% bracket): about $20,000. That’s a 30x multiplier on the parents’ or grandparents’ investment.
5-year-old, $5,000/year for 13 years, 7% return: The Roth grows to roughly $2.0 million tax-free by age 60. Starting later reduces the compounding runway, but the strategy still delivers a significant outcome.
Newborn, $3,000/year (more modest contribution): Even at a lower contribution level, the Roth reaches approximately $2.0 million tax-free by age 60. You don’t need to max the $5,000 limit to make this work.
Why This Matters
The Trump Account’s edge is the combination of three things: no earned income requirement (so you can fund it from day one), tax-deferred growth during the child’s highest-compounding years, and a clean Roth conversion pathway when they’re in their lowest tax bracket.
Compare that to a taxable brokerage account, where dividends and capital gains create drag every year, or a custodial Roth IRA, which requires the child to have earned income — unavailable during the years when compounding matters most.
The calculator helps you see the difference in concrete terms for your family’s specific numbers.
Key Assumptions
- Returns are assumed at the rate you select (default 7%), compounded annually. Actual returns will vary.
- Roth conversion is modeled over 4 years starting at the age you choose, with taxes estimated at the 12% federal bracket.
- The illustration assumes conversion taxes are paid from outside the account, preserving the full balance for tax-free growth. This is the recommended approach.
- This is for illustration only and is not investment, tax, or legal advice.
Next Steps
