You enter your current age, retirement age, annual contribution, existing Roth balance, and expected annual return. The tool compounds the existing balance to retirement, then separately compounds the annual contributions using the future-value-of-annuity formula. It adds both to get the total. The monthly income figure simply divides the total by 300 months (25 years) — it does not model variable withdrawal rates or required minimum distributions.
For 2025, the limit is $7,000 per year ($8,000 if you're 50 or older). Income phase-outs for direct Roth contributions in 2025: $150,000–$165,000 for single filers, $236,000–$246,000 for married filing jointly. These limits are adjusted periodically for inflation — check the IRS website for the current year's cap.
No. It assumes the same annual contribution every year. In practice, limits tend to rise over time, so your actual total may be higher if you max out each year.
A common assumption for a diversified stock portfolio is 7% (roughly the long-term real return of the S&P 500). Use a lower rate for conservative allocations or to account for inflation-adjusted returns.
Yes, provided you're at least 59½ and the account has been open for at least five years. Qualified distributions — including all the growth — come out federal-income-tax-free. State tax treatment varies but generally follows federal rules.
Yes. High earners may be partially or fully phased out of direct Roth IRA contributions. A backdoor Roth conversion is a common workaround — see the Roth Conversion calculator for that analysis.
