Roth IRA Contribution & Growth Calculator
Roth IRA Contribution & Growth Calculator
The Roth IRA Contribution and Growth Calculator helps you project the future value of a Roth IRA and understand the benefits of tax-free growth. A Roth IRA uses after-tax dollars, meaning all growth and withdrawals in retirement are completely tax-free. This makes Roth IRAs one of the most powerful wealth-building tools, especially for younger investors who expect higher tax brackets in retirement.
A young professional contributing the maximum to a Roth IRA from age 25 to 65 could accumulate over $1 million in tax-free savings at 8 percent average returns. The tax savings on that growth alone could be hundreds of thousands of dollars. You can withdraw your contributions at any time without penalty, providing flexibility that traditional retirement accounts lack.
Contribution limits for 2025 and 2026 are $7,000 for those under 50, with an additional $1,000 catch-up for those 50 and older. High earners may be restricted based on modified adjusted gross income, but a backdoor Roth IRA strategy involving a traditional IRA conversion is available.
Enter your current Roth balance, planned annual contribution, expected annual return, and time horizon in years. Enter your assumed tax rate in retirement for the Roth vs Traditional comparison. Press Calculate to see your projected balance, total contributions, tax-free earnings, and what a Traditional IRA would be worth after taxes.
For example, a 30-year-old contributing $7,000 annually for 35 years at 7 percent would accumulate approximately $967,000, with $245,000 in contributions and $722,000 in tax-free earnings. A Traditional IRA with the same inputs and 22 percent tax would be worth about $754,000 after taxes.

The Roth IRA is most beneficial if you expect to be in a higher tax bracket in retirement. Young professionals early in their careers are ideal candidates. Consider the backdoor Roth IRA strategy if your income exceeds direct contribution limits. This involves making a non-deductible traditional IRA contribution and converting it to Roth.
This calculator does not account for future changes in tax law, contribution limits, or income phase-out thresholds.
