Example: Estimating a FERS Annuity
Let’s walk through a real-world example to show how the calculator works.
- High-3 Average Salary: $85,000
- Years of Service: 22
- Additional Months: 6
- Retirement System: FERS
- Retirement Age: 63
Calculation:
- Total Service: 22 years + 6 months = 22.5 years
- Eligible Multiplier (since age ≥ 62 and service ≥ 20): 1.1% or 0.011
- Annual Annuity:
$85,000 × 22.5 × 0.011 = $21,037.50 - Monthly Annuity:
$21,037.50 / 12 = $1,753.13
The tool would instantly show:
- Annual Annuity: $21,037.50
- Monthly Annuity: $1,753.13
Understanding Your Federal Retirement Options
FERS (Federal Employees Retirement System)
- Introduced in 1987.
- Most federal workers today fall under FERS.
- Retirement benefit is based on High-3 salary, years of service, and a multiplier (typically 1% or 1.1%).
CSRS (Civil Service Retirement System)
- Applies to employees hired before 1984.
- Typically offers a higher multiplier (1.5% or more).
- Employees under CSRS do not pay into Social Security.

1. What is a High-3 average salary?
It’s the average of your highest-paid consecutive 36 months in federal service, typically near the end of your career.

Anyone hired after 1984 is automatically enrolled in FERS unless they chose to stay in CSRS during the transition.
3. Who qualifies for CSRS?
Federal employees hired before 1984, who did not switch to FERS, remain under CSRS.
4. What’s the difference in the annuity multiplier for FERS?
Under FERS, if you retire at 62 or older with 20+ years, your multiplier is 1.1%. Otherwise, it’s 1.0%.
5. How does age affect my FERS retirement annuity?
If you’re under 62 or have fewer than 20 years of service, you receive a smaller multiplier (1.0%).
