FERS Retirement Calculator
If you're a federal employee, your FERS pension is a defined benefit from years of service × high-3 salary. This computes the OPM formula so you know your baseline annuity.
FERS formula (OPM.gov): annuity = high-3 average salary × multiplier × years of service. Multiplier: 1.0% per year under age 62 (or 62+ with <20 yrs); 1.1% per year at age 62+ with 20+ years. Reductions: 10% off for a 50% survivor benefit, 5% for 25%; MRA+10 early retirement cuts 5% per year under 62 (waived at 30 yrs service, or 20 yrs at age 60). Not included: TSP, Social Security, or the FERS supplement — add those for total retirement income.
FAQ
How is the FERS pension calculated?
Your high-3 average salary × (1% or 1.1%) × years of service. At age 62+ with 20+ years you get the higher 1.1% per year.
What reduces my FERS annuity?
Electing a survivor benefit (10% off for a 50% benefit), retiring under MRA+10 before 62 (5% per year under 62, with waivers), and certain refunded or unpaid service.
Is the FERS supplement included?
No — this calculator models the basic annuity only. If you retire before 62, the FERS Supplement (Social-Security-like bridge) may add income until you reach 62. TSP and Social Security are separate.
