CSRS Retirement Annuity Calculations
The amount of the basic annuity payable upon your retirement under the Civil
Service Retirement System (CSRS) is directly related to:
- your length of creditable service and
- your highest 3 years' average salary.
Once the basic annuity is computed, based on length of service and your
earnings, it may be reduced:
- for any service for which you did not make retirement contributions ("deposit service")
- for service for which you have received a refund of retirement contributions
("redeposit

- to provide survivor
benefits for your spouse or former spouse after your death
- because you are retiring before age 55

examples) of calculating a CSRS retirement annuity:
