The Trump Account Growth Calculator projects an account balance from an initial amount, monthly contribution, annual interest rate, and number of years. It uses monthly compounding and reports final balance, total contributions, and modeled interest.
Formula
With monthly rate r = annual rate / 100 / 12 and n = years x 12:
If the rate is zero, the result is initial amount plus monthly contribution multiplied by the number of months.
Worked example
For 100 per month, 5% annual interest, and 10 years:
- Months:
10 x 12 = 120. - The calculator compounds the initial amount and each monthly contribution.
- Total contributions are
$1,000 + ($100 x 120) = $13,000. - Final balance and modeled interest are returned after rounding to cents.
Questions
Does the name imply a government benefit or guarantee?
No. The tool is a generic growth projection and does not verify eligibility, legislation, contributions, or account terms.
Are deposits made at the beginning or end of each month?
The formula treats recurring contributions as ordinary annuity payments under the module's implementation.
Can the rate be zero?
Yes. A zero rate uses simple addition rather than dividing by a zero monthly rate.
Limitations
The projection ignores taxes, fees, inflation, contribution limits, changing rates, and account-specific rules. Use current official program documents for any real account decision.
