The FERS Supplement (also called the Special Retirement Supplement, or SRS) is a temporary benefit that can significantly boost income for federal retirees before Social Security begins.
It is designed to bridge the gap between your retirement date and age 62.

What Is the FERS Supplement?
The FERS Supplement is an additional monthly payment paid to certain FERS retirees until age 62, when Social Security becomes available.
It roughly represents the Social Security benefit you earned during your federal career.
Who Qualifies?
You generally qualify if you retire with an immediate, unreduced FERS annuity, such as:
- MRA + 30 years
- Age 60 with 20 years
- Certain early retirement (VERA) cases
You usually do NOT qualify if:
- You retire under MRA+10 (unless postponed properly)
- You take a deferred retirement
- You leave federal service before eligibility
When Does It Start and Stop?
- Starts: When your FERS pension begins
- Stops: At age 62, regardless of whether you claim Social Security
How Is the FERS Supplement Calculated?
A common estimate:
(Years of FERS Service ÷ 40) × Age-62 Social Security Estimate
Example Calculation
- Estimated SS at 62: $2,000/month
- FERS service: 30 years
30 ÷ 40 = 0.75
0.75 × $2,000 = $1,500/month
Earnings Test
The supplement is subject to an earnings limit before age 62.
If you work and exceed the limit, your supplement may be reduced.
Timeline Impact
Example:
- 57: Pension + Supplement
- 62: Supplement ends
- 62+: Social Security begins
This is a major income transition point.
5 Common Mistakes
- Assuming everyone qualifies
- Forgetting it ends at 62
- Not planning for income drop
- Ignoring earnings limits
- Not modeling Social Security
TSP Strategy Impact
The supplement can reduce early withdrawals from TSP.
But once it ends, you may need to:
- Increase withdrawals
- Start Social Security
What to Do Next
Compare:
- With vs without supplement
- Income at 57 vs 62
- TSP needs
