Trump Account Growth Calculator

The Trump Account Growth Calculator projects what a child's Trump Account could grow to: the federal seed deposit, annual contributions up to the legal cap, and compound growth at the return you assume, year by year to age 18 or any target age you set. Enter the child's current age, whether the birth qualifies for the seed, the annual contribution, and an expected return.

How It Works

The account starts with the $1,000 government seed when the child qualifies (US-citizen children born from 2025 through 2028, under the program rules the calculator models). Each year through age 18 the annual contribution is added (the calculator enforces the$5,000 annual cap on contributions), and the balance compounds at your assumed return, producing a schedule of contributions, interest earned, and ending balance by age. Past 18 the projection continues growing without new contributions, mirroring the account's conversion into the young adult's own retirement-style account.

Parameters

| Input | Required | Meaning | |---|---|---| | Current age | Yes | The child's age, 0 to 17 | | Has seed | No | Whether the $1,000 federal seed applies (default yes) | | Annual contribution | No | 0 to$5,000 per year (default $5,000) | | Return rate | No | Assumed annual return (default 7%) | | Target age | No | Project to this age (default 18) |

Worked example

A newborn who qualifies for the seed, with the maximum $5,000 contributed every year at a 7$185,275 by age 18** on the calculator's schedule: $91,000 paid in ($1,000 seed plus $90,000 of contributions) and about$94,275 of growth. Halve the contribution to $2,500 and the ending balance roughly halves on the contribution side (the seed's compounding is unchanged), which is the arithmetic every family version of this decision runs on: time in the market is the seed's whole argument, and contributions you can actually sustain beat an ambitious schedule abandoned in year three. At a 5$147,000, a reminder to treat the return assumption as the speculative input it is.

What Trump Accounts are, briefly

Created by the 2025 tax law (the One Big Beautiful Bill Act), Trump Accounts are tax-deferred investment accounts for children: the Treasury seeds $1,000 for eligible newborns in the 2025 to 2028 window, parents and others may contribute up to$5,000 a year (with employers able to contribute part of that cap tax-free under the program's rules), funds are invested in diversified index funds, and the account becomes the child's own IRA-style account at 18, with withdrawals governed by those rules and taxed accordingly. The details that matter (eligibility, contribution sources, the age-18 transition) are statutory and may be refined by guidance; this calculator models the growth mechanics, not the legal advice.

Reading the projection responsibly

An 18-year projection is a compound-interest illustration, not a forecast: actual returns arrive in a disorderly sequence, fees and the fund's exact composition matter, and a smooth 7% line conceals drawdowns that real families must not panic through. The comparisons that are meaningful are between contribution levels and start ages under one consistent assumption: starting at birth versus age 5 costs the later starter four years of compounding on every contribution, which at 7% is roughly a fifth of the ending value, a fair quantification of "start early" for this specific vehicle.

Limitations

The calculator projects contributions at the start-of-year convention of its schedule and a constant return, and it enforces the $5,000 cap and the contribution stop at 18 as modeled. It does not apply taxes at withdrawal, account fees, inflation (all figures are nominal future dollars), or eligibility determinations beyond the seed toggle you set. Program rules are new and subject to official guidance; confirm the current terms before acting on a projection.

Frequently Asked Questions

Who gets the $1,000 seed?

Under the program rules modeled here, US-citizen children born from 1 January 2025 through 31 December 2028, once an account is opened for them. The toggle exists so families outside the window can project contributions alone.

Can contributions exceed $5,000 in a year?

Not within the program's cap as modeled; the calculator rejects contributions above $5,000. Employer contributions count within the same annual cap under the program rules.

What happens at 18?

Contributions stop in the projection, and under the program the account transitions to the young adult's own IRA-style account, with its withdrawal and tax rules applying from there. The projection can continue to any target age to show the compounding runway that transition preserves.
