The Roth IRA Calculator projects the tax-free growth of your Roth Individual Retirement Account, showing you how after-tax contributions can compound into a substantial nest egg that you will never pay taxes on again. The Roth IRA is widely considered one of the most powerful retirement savings tools available due to its unique tax treatment: you contribute money you have already paid taxes on, and in return, all growth and qualified withdrawals are completely tax-free.
Named after Senator William Roth who championed its creation through the Taxpayer Relief Act of 1997, the Roth IRA has become enormously popular, particularly among younger savers who expect to be in higher tax brackets in the future. Since you pay taxes on contributions at your current (potentially lower) rate, every dollar of growth escapes taxation entirely — a benefit that becomes more valuable the longer your money compounds.
The 2024 Roth IRA contribution limit is $7,000 ($8,000 if age 50+), but there are income eligibility limits. In 2024, the ability to contribute begins phasing out at MAGI of $146,000 for single filers and $230,000 for married filing jointly. Above $161,000 (single) or $240,000 (married), direct Roth contributions are not allowed — though the backdoor Roth IRA strategy provides a legal workaround.
Unlike Traditional IRAs, Roth IRAs have no required minimum distributions (RMDs) during the owner's lifetime. This makes the Roth an exceptional estate planning tool, as the account can continue growing tax-free for decades and be passed to heirs, who receive tax-free distributions (though they must take RMDs from inherited Roth IRAs under the SECURE Act's 10-year rule).
Another unique advantage is contribution flexibility: you can withdraw your original contributions (not earnings) at any time, for any reason, without taxes or penalties. This makes the Roth IRA a dual-purpose vehicle — retirement savings with emergency fund backup. However, withdrawing contributions reduces future tax-free compounding, so it should be a last resort.
The calculator uses the future value formula: FV = PV × (1+r)^n + PMT × [((1+r)^n − 1)/r]. Since Roth IRA growth is tax-free, the entire balance is available for withdrawal without tax reduction. Tax-free income uses the 4% rule. Lifetime tax savings estimates how much tax you avoid by having growth in a Roth rather than a taxable account (growth × retirement tax rate).
The Roth IRA balance represents money that is entirely yours — no future tax bill attached. Compare the tax savings figure to see how much the Roth structure saves versus a taxable account. A large gap between contributions and total balance indicates strong compound growth — the core advantage of the Roth IRA.

Roth IRA contributions are after-tax (no deduction), but qualified withdrawals are completely tax-free. Traditional IRA contributions may be tax-deductible, but withdrawals are taxed as income. The Roth is better if you expect higher future tax rates.
For 2024, the ability to contribute phases out between $146,000-$161,000 MAGI for single filers and $230,000-$240,000 for married filing jointly. Above these limits, direct contributions are not allowed.
A backdoor Roth IRA involves contributing to a non-deductible Traditional IRA and then converting it to a Roth IRA. This allows high-income earners to fund a Roth IRA despite exceeding the income limits. The pro-rata rule may apply if you have other Traditional IRA balances.
Yes. You can withdraw your original contributions (not earnings) at any time, tax-free and penalty-free, since you already paid taxes on them. Earnings withdrawn before age 59.5 may be subject to taxes and a 10% penalty.
No. Unlike Traditional IRAs and 401(k)s, Roth IRAs have no required minimum distributions during the owner's lifetime. This allows the account to continue growing tax-free indefinitely.
The Roth IRA 5-year rule states that earnings withdrawals are only tax-free if the account has been open for at least 5 years AND you are 59.5 or older (or meet other qualifying conditions). Contributions can always be withdrawn without meeting this rule.
A Roth conversion makes sense if you expect higher tax rates in retirement, have a long time horizon for tax-free growth, or want to avoid future RMDs. You will owe taxes on the converted amount in the year of conversion.
Excellent. Young people typically have lower tax rates and long time horizons — both favor the Roth. Paying taxes at a low rate now and letting decades of growth accumulate tax-free is one of the most powerful wealth-building strategies available.
Yes. There is no restriction on contributing to both. The $7,000 IRA limit and $23,000 401(k) limit are separate. Having both provides tax diversification in retirement.
Roth IRAs pass to heirs tax-free, though beneficiaries must deplete inherited Roth IRAs within 10 years under the SECURE Act. Since there are no lifetime RMDs, the account can grow for decades before being passed on.
