The FERS Pension Formula
Your FERS pension (Basic Benefit Plan annuity) is calculated using a straightforward formula:
Annual Pension = Multiplier × High-3 Average Salary × Years of Creditable Service
The Multiplier
The multiplier is either 1% or 1.1%, depending on your age and years of service at retirement:
- 1% multiplier: Applies to most FERS retirees
- 1.1% multiplier: Applies if you retire at age 62 or older with 20 or more years of service — a 10% bonus for staying longer
The High-3 Average Salary
Your High-3 is the average of your highest basic pay over any three consecutive years of service. This is typically (but not always) your final three years. It does not include overtime, bonuses, or other special pay.
Years of Creditable Service
Creditable service includes all years and months of civilian federal service, plus any military service you have bought back. Part-time service is counted proportionally.
Real-World Examples
Example 1: Retire at age 60 with 28 years of service and a High-3 of $85,000
- Pension = 1% × $85,000 × 28 = $23,800/year ($1,983/month)
Example 2: Retire at age 62 with 22 years of service and a High-3 of $95,000
- Pension = 1.1% × $95,000 × 22 = $22,990/year ($1,916/month)
Maximizing Your FERS Pension
Strategies to maximize your pension include:
- Working until age 62 with 20+ years to earn the 1.1% multiplier
- Maximizing your High-3 by timing promotions and pay increases
- Buying back military service time
- Avoiding early retirement reductions
