How does the FERS annuity formula work?

One of two calculations applies:

  • If you are under age 62: 1% x high-3 average salary x all years and full months (with months credited proportionately) of service.
  • If you are at least 62 years old with at least 20 years of service: 1.1% x high-3 average salary x all years and full months (with months credited proportionately) of service.

Note: Days beyond the last full month are added to any days beyond the last full month of additional credit for unused sick leave, using the same conversion formula applying to unused sick leave. Any time beyond the last full month after that formula is followed is not counted in the benefit calculation.
