Qualifying for a Retirement Benefit

Once you are vested in your retirement system, the basic formula for your retirement benefit depends on your age at retirement, your length of creditable service, your average annual rate of compensation and your group classification. These factors differ based on your membership date. Please refer to the appropriate retirement guide for additional information. 

If your membership date is prior to April 2, 2012, you can do a quick calculation on the State Retirement Board's Online Pension Calculator for a retirement estimate.
