Roth IRA Calculator

A Roth IRA is an individual retirement account funded with after-tax dollars. You get no tax deduction on the contribution, but qualified withdrawals in retirement — both your contributions and every dollar of investment growth — are completely tax-free. There are no required minimum distributions (RMDs) during your lifetime.

For 2026, you can contribute up to $7,500 to a Roth IRA ($8,600 if you're age 50 or older, which includes the $1,100 catch-up — the first-ever inflation increase to the IRA catch-up under SECURE 2.0). This limit applies to your combined Traditional and Roth IRA contributions, not each account separately.

Your ability to contribute directly to a Roth IRA phases out based on Modified AGI (MAGI). For 2026, the phase-out range is $153,000–$168,000 for single filers and $242,000–$252,000 for married filing jointly. Below the range, you can contribute the full amount; above it, you can't contribute directly at all; in between, your limit is reduced proportionally.

If your MAGI exceeds the phase-out range, you can still get money into a Roth IRA using the Backdoor Roth strategy: contribute to a non-deductible Traditional IRA (which has no income limit), then convert those funds to a Roth. The conversion can trigger tax under the IRS pro-rata rule if you have other pre-tax IRA balances — use the Backdoor Roth IRA Calculator to estimate that tax before converting.

There's no dollar cap on how large a Roth IRA can grow — only the annual contribution is limited. A 30-year-old who maxes out contributions every year at a 7% average return could accumulate well over $1,000,000 tax-free by retirement, all of it withdrawable with no federal income tax owed.
