# IRA - Roth Conversion Analysis Worksheet

This calculator computes the difference between the following two options:

• Option 1: Leaving the traditional IRA balance where it is.
• Option 2: Rolling the traditional IRA balance into a Roth IRA.

Notes

• Option 1 does not incur a tax liability in the year of conversion; Option 2 does.
• In order to create a fair comparison, the money that would have gone to pay taxes is assumed to be invested in a taxable account for Option 1.
• The distributions are annual and occur at the beginning of each year of retirement.

## Example

If your client has an existing balance in her traditional IRA of \$11,000 (\$1,000 of which is from nondeductible contributions), and she is currently in a zero tax bracket because she is in the first year of starting a new business, what would be the difference in retirement distributions between Option 1 and Option 2?

Field Input
Amount to convert from Traditional IRA to Roth IRA \$11,000
Nondeductible contributions in conversion \$1,000
Year of Conversion Accumulation Years Distribution Years
Federal tax rate 0% 28% 28%
Number of years 10 20
Annual rate of return 8% 5%

In this example, the total after tax distributions from the traditional IRA (Option 1) is \$21,369.12, and the after tax distributions from the Roth IRA (Option 2) is \$29,290.44 (a difference of \$7,921.32).

Notes

• The Taxable investment account accumulation field computes the amount of accumulated net interest on the amount of tax due at rollover.
• To evaluate the effect of a conversion from a regular to a Roth IRA without regard to any distributions, enter 1 year of distributions, a zero tax rate in the distribution years, and a zero annual rate of return for the distribution years.
