Roth IRA Calculator
Project your Roth IRA growth with tax-free compound interest over time. The Roth IRA is often considered one of the best retirement savings vehicles available, offering tax-free growth and tax-free withdrawals in retirement. This calculator helps you understand how your contributions can grow into substantial tax-free wealth.
Understanding Roth IRA Benefits
Unlike traditional retirement accounts, Roth IRA contributions are made with after-tax dollars, but all qualified withdrawals in retirement are completely tax-free—including decades of investment gains. This structure is particularly valuable for those who expect to be in higher tax brackets later or want tax diversification in retirement.
Additional unique benefits include no required minimum distributions (RMDs) during your lifetime, the ability to withdraw contributions (not earnings) anytime without penalty, and passing tax-free assets to heirs. These features make the Roth IRA exceptionally flexible compared to other retirement accounts.

Choose Roth if: You're in a lower tax bracket now, expect higher taxes later, want flexibility, or want to leave tax-free assets to heirs.
Choose Traditional if: You're in a high tax bracket now, expect lower income in retirement, or need the immediate tax deduction.
The Backdoor Roth IRA Strategy
High earners above the income limits can still fund a Roth IRA through the "backdoor" conversion:
1. Contribute to a non-deductible Traditional IRA 2. Convert the Traditional IRA to Roth IRA 3. Pay taxes on any pre-conversion gains (usually minimal if done quickly)
Important considerations:
- The pro-rata rule applies if you have existing traditional IRA balances
- Some portion of conversion may be taxable
- Must file Form 8606 with your taxes
- Consult a tax professional for your specific situation
