About Roth IRA Calculator
Formula
Future Value = Current Balance × (1+r)^n + Annual Contribution × [(1+r)^n - 1] / r With Roth, 100% of this future value is accessible tax-free in retirement, compared to Traditional where withdrawals are taxed as ordinary income.
Current Standards: 2026 Roth IRA limits: $7,000 base ($8,000 age 50+). Income phase-outs: $150,000-$165,000 single, $236,000-$246,000 married filing jointly. Earnings can be withdrawn tax and penalty-free after age 59.5 and 5 years of account ownership.
Frequently Asked Questions
Should I choose Roth or Traditional IRA?
Choose Roth if you expect your tax rate in retirement to be equal or higher than now, or if you value the flexibility of no RMDs. Choose Traditional if you're in a high tax bracket now and expect much lower retirement taxes. Many advisors recommend having both for tax diversification.
What's the backdoor Roth IRA strategy?
If your income exceeds Roth limits, you can contribute to a non-deductible Traditional IRA and immediately convert to Roth. You'll owe taxes only on any gains between contribution and conversion. This works best with no existing Traditional IRA balances due to pro-rata taxation rules.
Can I withdraw Roth IRA money early?
Contributions (not earnings) can be withdrawn anytime without tax or penalty since you already paid taxes on that money. Earnings withdrawn before 59.5 face a 10% penalty plus taxes, with exceptions for first home purchase ($10,000 lifetime), disability, and certain other situations.
When should I do a Roth conversion?
Convert in years when your income is unusually low: early retirement before Social Security, job transitions, sabbaticals, or years with large deductions. Converting fills up low tax brackets with tax-advantaged growth. Avoid converting amounts that push you into much higher brackets.
Why are there no RMDs for Roth IRAs?
Since Roth contributions were already taxed, the IRS doesn't require distributions to collect tax revenue. This makes Roth IRAs excellent estate planning tools since your heirs inherit tax-free and the account can continue growing. Note: Inherited Roth IRAs do have distribution requirements for non-spouse beneficiaries.
