Free Roth IRA calculator: project tax-free growth to retirement, check 2026 contribution and income limits, and estimate monthly retirement income.
Roth eligibility phases out at higher incomes. 'Single' includes head of household; 'Separate' means married filing separately while living with your spouse. MAGI is optional.
2026 IRS limits: $7,500 per year, or $8,600 if you are 50 or older. Estimates for planning only — investment returns vary and are not guaranteed. Not tax advice.

A Roth IRA grows tax-free and qualified withdrawals in retirement are completely tax-free. Our calculator projects your balance at retirement, factors in contribution limits, and estimates your tax-free monthly income.
Unlike traditional IRAs, Roth contributions are made with after-tax dollars, but all growth and withdrawals are tax-free in retirement. For someone in a higher tax bracket in retirement, or expecting tax rates to rise, Roth can save significant money.

Plan for catch-up contributions at 50+
For 2026 you can contribute up to $7,500 if you're under 50, or $8,600 if you're 50 or older (a $1,100 catch-up). That's the combined limit across all your traditional and Roth IRAs, and you can't contribute more than your taxable compensation for the year.
Your ability to contribute phases out by modified AGI (MAGI). Single or head of household: $153,000–$168,000. Married filing jointly: $242,000–$252,000. Married filing separately (lived with spouse): $0–$10,000. Below the range you can contribute the full amount; inside it your limit is reduced; at or above it you cannot contribute directly.
If your MAGI is above the limit you can't contribute directly, but many high earners use a backdoor Roth: contribute to a traditional IRA and convert it to Roth. Watch the pro-rata rule if you hold other pre-tax IRA money.
Contributions can be withdrawn anytime tax- and penalty-free. Earnings can be withdrawn tax-free after age 59½ AND once the account has been open 5+ years. Withdrawing earnings early may incur a 10% penalty plus tax.
Roth is generally better if you expect higher taxes in retirement or want tax-free withdrawals and no required minimum distributions. Traditional is better if you want the deduction now and expect lower taxes later.
The 4% rule suggests withdrawing 4% of your portfolio in the first year of retirement, then adjusting for inflation. A $500,000 Roth would provide about $20,000/year — all tax-free.
