Roth Conversion Break Even Calculator
Estimate Roth conversion break-even timing by comparing upfront tax cost with projected Roth and traditional IRA after-tax values.
For users focused on how long it may take investment growth to offset conversion tax cost.
The break-even estimate helps users understand how long a modeled Roth conversion may need before projected after-tax value is higher than the traditional account comparison.
The calculator uses user-entered assumptions for expected annual return, retirement age, retirement marginal tax rate, inflation, and tax payment method.
Market returns and future tax rates can differ materially from assumptions, so the break-even result should be treated as a sensitivity estimate.
