Roth IRA Calculator

Project your Roth IRA's tax-free growth and check your contribution limit against the income phase-out for your filing status.

Inputs

The 2026 Roth IRA contribution limit is $7,500 ($8,600 if you're 50 or older), before any income phase-out.

Used only to check your contribution limit against the Roth IRA income phase-out, not the growth projection itself.

How the calculation works

Projects your current Roth IRA balance forward at your expected annual return, adding the future value of contributing the same amount every year until retirement, the identical growth math a traditional IRA uses. The difference is tax treatment, not growth: Roth contributions are made with after-tax money, and qualified withdrawals in retirement are tax-free, so every dollar shown here is money you'd actually get to keep. Separately, this checks your modified adjusted gross income against the IRS's Roth IRA income phase-out for your filing status, since eligibility to contribute directly shrinks and eventually disappears above a certain income.

Formula

Projected Balance = Current Balance × (1 + r)^n + Annual Contribution × [((1 + r)^n − 1) ÷ r]. Max Allowed Contribution phases out linearly from the full 2026 limit to $0 across your filing status's MAGI range.

Examples

  • $10,000 balance, $7,000/year, 7% return, 20 years, MAGI well under the limit

    $325,665.29 projected balance; fully eligible to contribute up to $7,500

  • $20,000 balance, $7,500/year, 7% return, 15 years, MAGI in the single/HoH phase-out range

    $243,648.30 projected balance; only about $4,000.00 allowed at this MAGI, below the $7,500 entered
