The Roth IRA calculator projects the tax-free growth of your Roth IRA over time. Unlike a Traditional IRA, Roth contributions are made with after-tax dollars and all qualified withdrawals in retirement are completely tax-free — including decades of investment gains.
Why Tax-Free Growth Matters
On a $500,000 Roth IRA balance at retirement, you owe $0 in federal income tax on withdrawals. On a $500,000 Traditional IRA balance, you could owe $75,000-$125,000 or more depending on your tax bracket at withdrawal. The Roth advantage grows with the account — the larger the balance, the more tax-free dollars you preserve.
Tax-Free Withdrawal Value = Account Balance x 1.0 (no tax) Traditional IRA After-Tax = Account Balance x (1 - Marginal Tax Rate)
Example: $800,000 Roth = $800,000 in hand. $800,000 Traditional at 22% tax = $624,000 in hand. Roth wins by $176,000.

Backdoor Roth IRA
High earners above the income limit can still fund a Roth IRA via the backdoor Roth method: contribute to a non-deductible Traditional IRA (no income limit), then convert it to a Roth IRA. The conversion is taxable only on any earnings between contribution and conversion — typically minimal if done promptly. Congress has not eliminated this strategy as of 2025.
Frequently Asked Questions
How much will my Roth IRA be worth at retirement?⌄
It depends on your annual contributions, starting age, and investment return. $7,000/year from age 30 at 7% grows to about $1 million by 65. From age 40, the same contributions grow to $441,000. Time is the most powerful variable — starting a decade earlier nearly doubles the outcome.
Is there an income limit for Roth IRA contributions?⌄
Yes. For 2024, single filers earning above $161,000 and married filers earning above $240,000 cannot contribute directly to a Roth IRA. Between $146,000 and $161,000 (single) or $230,000 and $240,000 (married), the contribution limit phases out proportionally. High earners can use the backdoor Roth method as an alternative.
Can I withdraw Roth IRA contributions at any time?⌄
Yes. Roth IRA contributions (the money you put in, not earnings) can be withdrawn at any time with no tax or penalty, because you already paid tax on them. Earnings require you to be 59.5 or older and the account to be at least 5 years old for tax-free, penalty-free withdrawal.
Does a Roth IRA have required minimum distributions?⌄
No. Roth IRAs are the only retirement account with no required minimum distributions (RMDs) during the owner's lifetime. This makes them useful for estate planning — you can let the account grow indefinitely and pass it to heirs, who inherit it tax-free for distributions up to 10 years.
Should I convert my Traditional IRA to a Roth IRA?⌄
A Roth conversion makes sense if your current tax rate is lower than you expect in retirement, or if you want to eliminate RMDs. The converted amount is taxed as ordinary income in the conversion year. Spreading a large conversion over several years keeps you in a lower bracket each year.
