How to Use This Calculator
- Enter your Years of Service — total credited years in the pension plan.
- Enter your Final Average Salary — check your plan document for whether it uses final year or a multi-year average.
- Enter your plan's Benefit Multiplier — typically 1.5%–2.5% per year of service.
- See your estimated Annual and Monthly Pension instantly.
- Use the Early Retirement tab to see how retiring before full retirement age reduces your benefit.
Formula
Annual Pension = Years of Service × Final Average Salary × Benefit Multiplier
Early Retirement: Reduced Annual Pension = Full Pension × (1 − Years Early × Reduction Rate)
COLA Adjusted Year N: Starting Pension × (1 + COLA Rate)^N
Example
Example: 25 years of service, $75,000 final salary, 2% multiplier.
- Annual Pension: 25 × $75,000 × 2% = $37,500/year
- Monthly Pension: $3,125/month
- Income Replacement Rate: 50% of final salary
- With 2% COLA, pension grows to ~$3,812/mo by year 10
Frequently Asked Questions
- The standard formula is: Annual Pension = Years of Service × Final Average Salary × Benefit Multiplier. For example: 25 years × $75,000 × 2% = $37,500/year ($3,125/month).
- High-3 averages your three highest consecutive years of salary. High-5 averages five years. High-3 typically results in a slightly higher pension since it captures peak earning years more precisely. Federal FERS uses High-3.
- Retiring before your full retirement age triggers a reduction, often 5% per year. Retiring 5 years early with a 5% reduction results in a 25% lower lifetime benefit. Some plans also use a vesting schedule.
- COLA (Cost of Living Adjustment) is an annual increase to your pension benefit to keep pace with inflation. Federal retirees under CSRS receive a COLA equal to the full CPI increase; FERS retirees get a reduced COLA (CPI minus 1%).
- A survivor benefit reduces your pension payment to provide continued income to a spouse after your death. Federal employees under FERS can elect a 25% or 50% survivor benefit, which reduces the retiree's payment by 5% or 10% respectively.
