About the Roth IRA Calculator
A Roth IRA is an individual retirement account funded with after-tax money. Your investments grow tax-free and qualified withdrawals in retirement are tax-free. This calculator projects your balance at retirement and compares it with a traditional IRA, where you get a tax deduction now but pay income tax on withdrawals.
How to use it
- Enter your age, retirement age, current balance and yearly contribution.
- Set an expected return and your tax rate now and in retirement.
- Press Project my Roth IRA to see the tax-free balance and the comparison with a traditional IRA.

Roth versus traditional IRA
- Roth is often better if you expect a higher tax rate in retirement than today.
- Traditional is often better if you expect a lower tax rate later and want the deduction now.
- Roth contributions (not earnings) can be withdrawn at any time without tax or penalty.
- Roth IRAs have no required minimum distributions during your lifetime.
Roth IRA rules to know
Qualified withdrawals of earnings generally require the account to be open for five years and you to be age 59½ or older. Early withdrawals of earnings may be taxed and penalized.
