Part-time service note: OPM prorates the pension for any part-time service by the fraction of full-time hours you actually worked. If you had part-time periods, enter your proration factor in the Part-Time Service section below so your estimate reflects it, and confirm the exact factor with your HR office or OPM.

CSRS to FERS Transfer

Did you transfer from the Civil Service Retirement System (CSRS)?

Your Military Service

Veterans may receive additional creditable service toward retirement by making a military deposit.

Part-Time Service

Part-time schedules prorate your pension. Your High-3 still uses full-time pay rates, but the earned annuity is multiplied by the share of full-time hours you actually worked.
