Tax Bracket Runway

Your income vs. available Roth conversion space in each bracket
🔄

Annual Conversion Opportunities

Maximum to convert per year within each bracket
Bracket Max Annual Conversion?Max Roth conversion per year to reach the top of this bracket without spilling into the next. Federal Tax Cost?Federal income tax on the converted amount in the year of conversion. Effective Rate?Blended tax rate on the conversion only — often lower than the bracket rate. Net into Roth?After-tax dollars that land in your Roth IRA this year. Roth Value at Age ?Projected tax-free Roth value at your plan age. Conversions occur during your window only; the Roth then compounds untouched to your plan age. Taxes assumed paid from outside funds.
Note: “Roth Value at Age” reflects conversions during your window only, then tax-free compounding to your plan age. Key assumption: conversion taxes are paid from outside funds — the full converted amount stays invested in the Roth. Federal tax only; state taxes not included. 2025 IRS brackets.

Longevity Value Comparison

What each strategy is worth over your full lifetime vs. leaving money in a traditional IRA
Strategy Total Converted?Total dollars shifted into Roth over all years to your plan age. Total Tax Paid Now?Total upfront federal tax across all conversion years. Roth at Plan Age?Projected total tax-free Roth IRA value at your plan age. Traditional IRA (After-Tax)?Yes — this is the projected after-tax value you would actually pocket if you left your money in the traditional IRA, grew it at your entered growth rate to your plan age, then withdrew and paid taxes on the entire balance in one lump sum at the Future Withdrawal Rate you entered. It is a single-event, full-liquidation snapshot used as a direct comparison against your Roth outcome. Lifetime Advantage?Net benefit of converting vs. leaving money in a traditional IRA.
Assumptions: Annual conversions at each bracket’s max continue every year to your plan age. Traditional IRA grows at the same rate; after-tax value applies your assumed future withdrawal rate. No state taxes. For illustration only.

📒 How This Calculator Works — Our Core Assumptions

Converted funds stay fully invested. The entire converted amount moves into your Roth IRA and compounds at your entered growth rate. We do not reduce the amount by the taxes owed — the tax is treated as a separate expense paid from outside the IRA.

Taxes are paid from outside funds — not from the IRA. We assume you pay the annual conversion tax from a separate source (savings, checking, or a taxable account). This means every converted dollar lands in the Roth intact and grows 100% tax-free from day one. This is the scenario where conversions are most advantageous.

You convert only during your defined window, then stop. Use the “Conversion Window” fields above to set when conversions start and stop. After the window closes, both your Roth and any remaining traditional IRA balance continue growing at your entered rate to your plan age — no further conversions assumed.

Tax is calculated bracket-by-bracket, not as a flat rate. Each converted dollar is taxed only at the rate for the specific IRS bracket it falls in. This is how the progressive tax system actually works — converting $50,000 does not mean all $50,000 is taxed at your top rate.
