Roth IRA Calculator
See how a Roth IRA could grow over the years. Qualified withdrawals in retirement are tax-free.
When to use this calculator
Use this calculator to see how regular Roth IRA contributions might grow. A Roth IRA is funded with after-tax money, and qualified withdrawals in retirement are tax-free, so the growth shown is what you may keep.
Example Roth IRA balances
How this calculator works
We grow your current balance at the return you enter and add one contribution at the end of each year. The 2026 IRS contribution limit used here is $7,500 for people under 50 (higher for 50 and older), and it is shared with any traditional IRA. Income limits can reduce or block Roth contributions, so check IRS rules.
Step-by-step example
Using these inputs: Current Roth IRA balance ($): 0; Yearly contribution ($): 7000; Years until withdrawal: 30; Expected yearly return (%): 7.
Contributing $7,000 a year for 30 years at a 7% return gives about $661,226. You contribute $210,000 and $451,226 is tax-free growth. The calculator also checks that $7,000 is within the $7,500 yearly limit.
Tips for a better estimate
- Check the income limits. High earners may not be able to contribute directly.
- Contribute early in the year if you can, so your money has more time to grow.
- Keep contributions within the yearly limit. Excess contributions can trigger a penalty.

You pay tax on the money now, but growth and qualified withdrawals later are tax-free.
Is the return guaranteed?
No. Investment returns vary, and the result is only an estimate.
Who can contribute?
You need earned income, and high earners may be limited. See the IRS website for current limits.
What is the Roth IRA limit?
The calculator uses $7,500 for 2026. Limits can change each year and have catch-up amounts for people 50 and older. Check irs.gov.
When can I withdraw from a Roth IRA?
You can withdraw your contributions at any time. Earnings are tax-free if you are 59 and a half and the account has been open five years.
Roth IRA or 401(k)?
