Roth conversion scenario

This is a simplified comparison. It assumes you pay conversion tax from outside funds and does not model bracket stacking or every IRS rule.

Estimated conversion tax

$12,000

Simplified current-rate estimate

Converted Roth value

$193,484

Modeled tax-free qualified value

Traditional after-tax value

$147,048

Modeled using future tax rate

Modeled advantage

$34,436

Scenario result: Convert now

Estimated tax to convert: $12,000. This assumes the tax is paid from outside the converted account.

What this result means

A conversion can be more attractive when you pay tax at a lower rate today than the rate you expect later. A real conversion can push income into higher brackets, affect credits and Medicare premiums, and interact with other IRA balances.

Important limitations

This tool does not calculate exact progressive tax liability, state tax, pro-rata taxation, required minimum distributions, or the value of using the conversion tax money elsewhere. Consult a tax professional before converting.
