Example GS Retirement Calculation

Let’s look at a practical example:

Scenario

High-3 Salary: $90,000
Years of Service: 25
Retirement Age: 62
Retirement System: FERS

Result

Multiplier applied: 1.1%
Estimated Annual Pension: $24,750
Estimated Monthly Pension: $2,062.50

This example shows how retiring at age 62 with sufficient service years can significantly increase your pension under FERS.

Understanding FERS vs CSRS Multipliers

FERS Multiplier Rules

1.0% for most retirements
1.1% if:
- You retire at age 62 or older
- You have at least 20 years of service

CSRS Multiplier Rules

1.5% for first 5 years
1.75% for next 5 years
2.0% for service beyond 10 years

The calculator automatically applies the correct multiplier so you don’t have to memorize complex rules.
