Analytical Proof & Invariants

Machine Precision

Governing Mathematical Formula:

Future Tax-Free Advantage = FV_Roth - (FV_Traditional - Future Taxes)

Step-by-Step Mathematical Derivation

Upfront Tax Obligation

Tax Due = Conversion Amount × Current Marginal Tax Rate.

Compounding Symmetry

If tax rates are identical today and in retirement, Traditional and Roth produce mathematically equal net wealth. If future tax rates rise (t_future > t_current), Roth conversion produces significant tax alpha.

Frequently Asked Questions

Should I pay Roth conversion taxes out of the converted balance? +

No! You should always pay conversion taxes with outside non-retirement cash reserves. Withholding taxes from the conversion reduces compound principal and may trigger early withdrawal penalties if under age 59½.
