Retirement Benefits

New Online Tool for Service Credit Purchase

We’ve expanded our online features to provide you with an actuarial equivalent reduction (AER) calculator.

As of January 1, 2020, new service credit purchase elections must be paid in full by your retirement date. If you are retiring after January 1, you can choose to convert your balance to an AER. An AER reduces your retirement benefit every month by an actuarially equivalent amount of your balance remaining at retirement. Even with the AER, you will still receive an increase in your monthly retirement benefit.

Effective January 18, log in to your myCalPERS account and follow the links to view your service credit purchase details, then select the link for the AER Calculator. The calculator provides you with an AER estimate by using your projected future retirement date, or by using a date you select. Your balance will project forward to the retirement date being used to determine your AER amount. The result will provide you with your estimated AER amount if you convert your remaining service credit purchase balance to an AER at retirement.
