Roth IRA Conversion Calculator (Advanced)
Roth IRA Conversion Calculator (Advanced)

With a Roth conversion, the taxable portion of your traditional IRA (deductible contributions and earnings) is subject to tax in the year of conversion. This calculator compares two scenarios: (1) The full or partial conversion of a traditional IRA to a Roth IRA, and (2) No traditional-to-Roth conversion. The calculator assumes that you'll pay any conversion taxes from other assets, and determines (for scenario 2) the amount you could have earned on that "side fund" had you not converted. For both scenarios, all required minimum distributions (RMDs) are also assumed to be invested in the side fund. The calculator estimates the IRA accumulation, and RMD distributions, for the IRA owner and up to three beneficiaries, (you can specify one spouse beneficiary and up to two non-spouse beneficiaries). Total after-tax dollars are compared.

* If you have multiple traditional IRAs, you must pro-rate your nontaxable balance among them. The IRS provides a worksheet in Publication 590-B.

Conversion taxes are paid from other assets.

The general RMD starting age is age 72.

Lifetime RMD calculation does not account for special rules that apply when spouse is more than 10 years younger than IRA owner.

Death occurs on last day of the year.

Conversion occurs at beginning of year.

Federal estate tax and possible credit for estate taxes paid are not accounted for; state income and death taxes and credits are also not taken into account.

All taxes are paid at end of year incurred.

RMDs are deposited into a side fund and grow at the specified annual rate of retiurn. Amount(s) equivalent to any conversion tax that would be owed as a result of the Roth conversion are also deposited into the side fund and grow at the specified annual rate of return.

Assumes spouse beneficiary rolls over inherited IRA to own IRA, and RMDs start when spouse reaches age 72.

Does not take into account special rule that says RMDs can be taken over owner's remaining life expectancy if longer then the beneficiary's.

Assumes separate accounts established for beneficiaries--beneficiaries' own life expectancy used for RMDs if the indiviual is no more than 10 years younger than the IRA owner, or is disabled, chronically ill, or the spouse or a minor child of the IRA owner. Otherwise, the entire account must be distributed within 10 years.
