FERS Retirement Guide for Federal Employees
The Federal Employees Retirement System (FERS) goal was to provide federal workers with a retirement system that balances guaranteed income, savings, and Social Security benefits.
It is often described as a “three-legged stool” because it relies on three separate sources of retirement income: a pension, Social Security, and the Thrift Savings Plan (TSP).
Retirement Eligibility Rules
FERS eligibility depends on age and years of service. The following table outlines common scenarios:
*Minimum Retirement Age (MRA) ranges from 55 to 57, depending on birth year.
Retiring at MRA with 10–29 years of service usually triggers a 5% reduction per year under age 62 unless specific exemptions apply.
How to Calculate Your FERS Pension
Calculating your FERS pension may seem complicated at first, but it’s straightforward once you understand the formula and the factors that go into it.
Step 1: Determine Your High‑3 Average Salary
Your High‑3 is the average of your highest-paid 36 consecutive months of basic federal pay. This includes:
- Basic pay
- Locality pay
- Certain other pay adjustments
If your highest-paid 36 months are $95,000, $100,000, and $105,000, the average is calculated as:
Step 2: Calculate Total Creditable Service
Add up all years and months of service that count toward retirement:
- Full-time federal service
- Part-time service (prorated)
- Purchased military service
- Unused sick leave (converted to full-time years)
Here is an example:
Step 3: Determine the Correct Multiplier
The FERS formula uses a multiplier that depends on your retirement age and years of service:
Step 4: Apply the Pension Formula
- High-3 = $100,000
- Service = 20 years
- Multiplier = 1.1% (retiring at 62+)
Step 5: Convert to Monthly Pension
Step 6: Adjust for Optional Factors (If Applicable)
How Your FERS Pension Is Paid
Once eligible and separated from service:
- The pension is paid monthly for life.
- Cost-of-living adjustments (COLAs) may be applied annually.
- Provides stable, predictable income compared to lump-sum payouts.
