Only one number? Try the Roth IRA Calculator

Roth IRA Planner

A Roth IRA is an account where you pay tax on the money you put in, and qualified withdrawals in retirement are not taxed. Enter the amount already saved, the yearly contribution, the years until you retire, and the return you assume. The calculator shows the projected balance and compares it with a traditional IRA taxed at withdrawal.

Frequently asked questions

Are Roth IRA withdrawals always tax free?

Qualified withdrawals are tax free. Withdrawals that do not meet the rules can be taxed and may carry a penalty, so check the rules for your account before you withdraw.

What is the yearly contribution limit?

The IRS sets it each year, and the limit below the catch-up age is the figure the calculator checks. Older savers may add a catch-up amount. Check the IRS website for the current figure.

Does the calculator include income limits?

No. Whether you can contribute to a Roth IRA depends on your income and filing status, which the calculator does not check.

Why does the traditional IRA come out lower?

Its balance is taxed when you withdraw it. The tax rate you enter decides how much is left after that tax, so a higher expected rate makes the traditional account look worse.

Can I contribute to both a Roth and a traditional IRA?

Yes, but the yearly limit applies to the total you put into all your IRAs together, not to each account separately.
