FERS Retirement Calculator — Free Pension Estimator 2026 — Free Online Tool
Estimate Federal Employees Retirement System annuity payouts & SRS supplement.
The FERS basic annuity is calculated as: High-3 Salary × Service Years × Multiplier (1.0% or 1.1%). Example: $95,000 High-3 salary with 25 years at Age 62 (1.1% multiplier) yields $26,125/year ($2,177/month).
Official OPM Methodology: FERS annuity calculations apply 1.0% per year of service, or 1.1% per year if retiring at Age 62+ with 20+ years of service. All calculations use official Office of Personnel Management (OPM) rules.

FERS Pension Summary
How the FERS Retirement Calculator Works
The FERS Retirement Calculator enables federal employees covered under the Federal Employees Retirement System (FERS) to estimate their defined-benefit pension annuity. The calculator implements official Office of Personnel Management (OPM) formulas, factoring in your High-3 average salary, total creditable years and months of service, retirement age, and applicable pension multipliers.
How FERS Pension Is Calculated
Your basic FERS retirement annuity is computed using a straightforward formula:
Does Federal Retirement Calculation Include Locality Pay?
Yes! Official OPM rules state that basic pay for your High-3 average salary calculation includes locality pay, special salary rates, and regular night differential. However, it excludes overtime pay, annual performance bonuses, awards, travel allowances, holiday pay, or military differential pay.
FERS Retirement Calculation with Sick Leave
Unused sick leave at retirement is converted directly into creditable service time using the OPM standard chart where 2,087 hours of sick leave equals 1 full year of service (or ~174 hours per month). For instance, 1,044 hours of unused sick leave adds 6 months (0.5 years) of service time, increasing your lifetime pension payout.
Step-by-Step Example of FERS Retirement Calculation
Scenario: Federal employee retiring at Age 62 with 25 years of service, 1,044 hours of unused sick leave (0.5 years), and a High-3 Average Salary of $100,000 (including locality pay).
- Total Creditable Service = 25 years + 0.5 years (sick leave) = 25.5 years
- Multiplier Eligibility = 1.1% (Age 62+ WITH 20+ years of service)
- Gross Annual Pension = $100,000 × 25.5 × 0.011 = $28,050 / year ($2,337.50 / month)
- Full Survivor Benefit (10% reduction) = $28,050 × 0.90 = $25,245 / year ($2,103.75 / month net)
- Spouse Protection = Surviving spouse receives $1,168.75 / month for life if retiree passes away
How Long Does FERS Retirement Pension Last?
FERS pension benefits last for your entire lifetime. Once OPM approves your retirement application, monthly pension payments continue until your death. If you elect a survivor benefit (50% or 25%), monthly payments continue to your surviving spouse for the rest of their lifetime. Annual Cost of Living Adjustments (COLA) are applied starting at Age 62 to protect against inflation.
FERS Pension vs. Social Security & TSP
FERS retirement is built on a "three-tiered" retirement structure:
- FERS Basic Annuity: Guaranteed monthly pension paid for life by OPM.
- Social Security: Monthly benefit earned through federal payroll tax contributions.
- Thrift Savings Plan (TSP): Defined contribution account similar to a 401(k), featuring employee contributions and up to a 5% agency match.

Formula & Specifications
Gross Annual Annuity = High-3 Salary × Total Service Years × Multiplier (1.0% or 1.1%). Net Annuity = Gross Annuity − Survivor Reduction (10% or 5%). SRS = (Service Years / 40) × Est. Social Security at 62.
