FERS Retirement Calculator
Estimate your FERS basic annuity — the federal pension — from your high-3 average salary, years of service and retirement age, with the standard or enhanced multiplier.
Rough estimate of the FERS basic annuity only — not financial or benefits advice. It does not include the special retirement supplement, survivor-benefit or early-retirement (MRA+10) reductions, unused sick leave, deductions for taxes/FEHB/FEGLI, COLAs, or the TSP and Social Security parts of FERS. Confirm with OPM or your HR/benefits office.
How the FERS basic annuity is figured
The pension part of FERS — the basic annuity — is your high-3 average salary multiplied by your years of creditable service and a multiplier. The multiplier is 1% in most cases, or 1.1% if you retire at age 62 or older with at least 20 years of service. So a $90,000 high-3 with 30 years at 62 works out to $90,000 × 30 × 1.1% = $29,700 a year.
What this estimate leaves out
FERS has three parts — the pension, the TSP, and Social Security — and this tool estimates only the pension. It doesn’t include the special retirement supplement, survivor-benefit or MRA+10 early-retirement reductions, unused sick leave, COLAs, or deductions for taxes and insurance, so treat it as a rough figure and confirm with OPM. For the TSP side, see the 401(k) calculator (the TSP works the same way); to project growth, the compound interest calculator.
Frequently asked questions
How is the FERS pension calculated?
The FERS basic annuity is your high-3 average salary × years of creditable service × a multiplier. The multiplier is 1% in most cases, or 1.1% if you retire at age 62 or older with at least 20 years of service. For example, a $90,000 high-3 with 30 years at age 62 is $90,000 × 30 × 1.1% = $29,700 a year.
What is the “high-3” salary?
Your high-3 is the highest average basic pay you earned over any three consecutive years of service — usually your last three years. It drives the whole calculation, so a higher high-3 means a larger pension.
What does this FERS estimate leave out?
FERS retirement has three parts; this estimates only the basic annuity (pension). It excludes the FERS special retirement supplement, survivor-benefit and early-retirement reductions, unused sick leave credit, COLAs, taxes and insurance deductions, and your TSP and Social Security. Treat it as a rough figure and confirm with OPM.
