Roth Conversion Calculator

Analyze converting your Traditional IRA to a Roth IRA. See how paying taxes now at your current rate compares to deferring taxes until retirement. Compare no conversion, full conversion, and annual partial conversions side by side.

How Roth Conversions Work

A Roth conversion moves pre-tax Traditional IRA assets into a after-tax Roth IRA. You pay income tax on the converted amount today, but the money then grows tax-free and can be withdrawn without tax in retirement. This strategy is most beneficial when you expect to be in a higher tax bracket in retirement or when current tax rates are temporarily low.
