IRA to Roth IRA Conversion Calculator (Married)
This calculator helps couples estimate the maximum amount they can convert from a Traditional IRA to a Roth IRA in 2025 without moving into a higher federal tax bracket. It calculates federal and state taxes owed on the conversion and projects how long it may take to fully convert your IRA balance based on your combined income and retirement timeline. Enter your ages, joint income, IRA balance, and state tax rate to determine your optimal conversion amount and tax implications under the latest 2025 tax brackets for married filing jointly. The tool also identifies your remaining “room” before reaching the next bracket, helping you plan efficient multi-year conversions while managing Required Minimum Distribution (RMD) rules at age 73. Use this calculator to model how strategic Roth conversions can reduce lifetime taxes, minimize RMD exposure, and create more tax-free income in retirement.
❓ FAQ Section
How does this calculator differ for married filers?
This version uses the 2025 Married Filing Jointly tax brackets and standard deduction, allowing couples to evaluate conversions based on their combined income and shared retirement assets.
What does “optimal conversion” mean in the results?
The optimal conversion amount is the maximum you can convert this year without entering the next federal tax bracket. The calculator estimates your total tax due (federal and state) on that amount.
Why do some results show a warning about age 73?
Conversions that extend past age 73 may overlap with Required Minimum Distributions (RMDs). RMDs cannot be converted to a Roth, so this helps you plan conversion timing before RMDs begin.
How can married couples benefit from Roth conversions
Strategic conversions can help reduce future RMDs, shift growth into tax-free accounts, and lock in today’s lower tax rates before potential future increases. Couples can often convert more than single filers while staying in the same bracket.
Can this calculator replace personalized tax advice?
No. This tool uses 2025 tax brackets and general assumptions. It does not consider itemized deductions, spousal income variations, or future law changes. Always consult a qualified tax professional or financial advisor for individualized planning.
