Formula & Methodology

Future value = current balance compounded at the assumed return plus the future value of annual contributions.

Frequently Asked Questions

What makes a Roth IRA different?

Contributions are made with after-tax dollars, and qualified withdrawals in retirement are tax-free, so investment growth is never taxed.

Are there contribution limits?

Yes. The IRS sets annual contribution limits and income phase-outs. This calculator does not enforce them, so check current rules.

Can I withdraw contributions early?

Yes. You can withdraw your own contributions (but not earnings) at any time without tax or penalty, subject to rules.
