The Methodology

How the Roth IRA Calculator works

A Roth IRA is one of the most powerful tax-advantaged accounts available to U.S. savers. You pay tax today, but every dollar of growth — and every withdrawal in retirement — comes out completely tax-free.

  1. 01

    Validate eligibility

    We apply the IRS MAGI phase-outs for your filing status to confirm your full, partial, or zero contribution.

  2. 02

    Project future value

    We compound your contributions with the standard future-value formula across your full saving horizon.

  3. 03

    Compare Roth vs Traditional

    We benchmark your after-tax Roth balance against the equivalent Traditional outcome at your retirement bracket.

Core formula
FV = PV(1+r)n + PMT × [((1+r)n − 1) / r]
