Wisconsin Retirement System (WRS) Forfeited Service Cost Calculator

This calculator lets you produce an unofficial estimate of your cost to purchase WRS forfeited service. It is a tool to aid you in deciding whether to purchase your forfeited service. For an official cost estimate and application to purchase forfeited service, please contact us.

You forfeit WRS creditable service when you take a lump sum separation benefit of your employee-required WRS contributions. Under certain conditions, you are eligible to "buy back" these years of forfeited service. Buying back WRS service usually increases the amount of your WRS retirement benefit.

We strongly recommend that you use the Retirement Benefit Calculator to calculate a more accurate projection of how much buying your forfeited service would increase your retirement benefit at the time you plan to retire. For more detailed information about WRS retirement benefits, read the following brochures:

Estimating the Return on Your Investment When Buying Service

You earn the largest rate of return on a forfeited service purchase when that service decreases your age reduction and/or increases the years of military service credit for which you are eligible. It also increases the years of creditable service in a formula annuity calculation.
 
The calculator estimates the number of years it would take to recover your investment by dividing the total service purchase cost by the estimated annual benefit increase. The length of time to recover the cost of a service purchase may be reduced by the amount of any annual WRS dividend increase you receive after retirement. In the following example, the service purchase investment is recovered in 5 years.
 
Example: Cost to Purchase Service ÷ Estimated Annual Increase = Years to Recover Investment
$18,000 ÷ $3,600 =    5
 
The calculator also calculates the rate of return on your investment by dividing the estimated annual increase by the estimated cost to purchase service. In the following example, the rate of return is 20%.
 
Estimated Annual Increase    ÷ Cost to Purchase Service  = Rate of Return
$3,600 ÷ $18,000  =    .20 or 20%
