How This Is Calculated

This calculator projects the future value of a Roth IRA using the compound interest formula with annual contributions. All growth and qualified withdrawals are completely tax-free.

Contribution limits (2024): $7,000 per year if under age 50, $8,000 per year if 50 or older (includes $1,000 catch-up). Contributions are limited to your earned income for the year.

Income limits: Roth IRA contributions phase out at higher incomes. For 2024, the phase-out begins at $146,000 MAGI for single filers and $230,000 for married filing jointly. Above these limits, you may use a "backdoor Roth" strategy.

Growth formula: The calculator uses A = P(1+r)^t + PMT × [((1+r)^t - 1) / r], where P is current balance, r is the annual return, t is years until retirement, and PMT is the annual contribution. The key advantage is that all earnings grow and are withdrawn tax-free.

Contribution limits: $7,000 (under 50) / $8,000 (50+) for 2024. Income phase-out: $146K-$161K (single), $230K-$240K (MFJ). Assumes tax-free growth and qualified withdrawals.

Frequently Asked Questions

Roth IRA vs Traditional IRA — which is better?

A Roth IRA uses after-tax contributions but offers tax-free growth and withdrawals in retirement. A Traditional IRA uses pre-tax contributions (tax-deductible now) but withdrawals are taxed as income. Roth is generally better if you expect to be in a higher tax bracket in retirement.

When can I withdraw from a Roth IRA?

You can withdraw your contributions (not earnings) at any time, tax-free and penalty-free. To withdraw earnings tax-free, you must be 59½ or older AND have had the account for at least 5 years (the 5-year rule).

What are the Roth IRA contribution limits for 2024?

For 2024, the contribution limit is $7,000 if you are under age 50, and $8,000 if you are 50 or older (includes $1,000 catch-up contribution). Contributions are phased out at higher incomes.

Can I contribute to both a 401(k) and a Roth IRA?

Yes, you can contribute to both a 401(k) and a Roth IRA in the same year. The 401(k) limit ($23,000 in 2024) is separate from the IRA limit ($7,000 or $8,000 if 50+). Having both provides tax diversification.
