FERS Annuity Supplement Guide
Are you thinking about retiring under Federal Employees Retirement System (FERS) soon — and wondering how you’ll get paid until you hit Social Security age? The FERS annuity supplement can help thousands of hardworking federal and postal employees like you stay financially safe during that gap.
Here’s a friendly, straightforward guide to everything you need to know about the FERS annuity supplement — what it is, who qualifies, how it’s calculated, and what to watch out for.
What is the FERS Annuity Supplement?
The FERS annuity supplement is a temporary benefit from Office of Personnel Management (OPM). It acts like a “bridge” for FERS retirees who leave federal service before they become eligible for Social Security benefits at age 62.
In other words: if you retire early, you’ll start getting your regular FERS annuity. The supplement adds extra monthly income until you turn 62 — when Social Security kicks in.
You don’t need to file a separate form. When you apply for retirement, OPM checks automatically whether you’re eligible for the supplement and adds it to your check.
Who Qualifies for the Supplement?
You get the supplement only if you’re under FERS (not under the older CSRS plan) and you retire early — before age 62.
Here are typical ways to qualify:
-
Retire at your Minimum Retirement Age (MRA) plus at least 30 years of service, or
-
Retire at age 60 with at least 20 years of service.
-
Some under special provisions — like law enforcement, firefighting, or certain hazardous-duty jobs — may also qualify under earlier rules.
Things that usually disqualify you: a “deferred retirement,” disability retirement, or retiring under the “MRA + 10” rule.
How the Supplement Gets Calculated
OPM estimates what your Social Security benefit would be at age 62 (assuming 40 years of covered work). Then the supplement is proportional to how many years you actually worked under FERS.
A rough formula often used:
For example: say your projected Social Security benefit at 62 is $20,000 per year, and you have 20 years of FERS service — then your supplement would be roughly $10,000 annually.
When you get monthly payments, that annual amount gets divided monthly.
How Long You Get It — And When It Ends
You receive the supplement every month until whichever happens first:
-
The month before you first become eligible for Social Security, or
-
The last month you turn 62.
Once you hit 62 and start Social Security, the supplement stops. There’s no overlap.
Why This Matters — Pros and Trade‑offs
The FERS supplement gives you soft landing if you retire early. It gives income where otherwise there would be none until 62.
But it isn’t perfect. For example:
-
The supplement does not grow with inflation — no cost‑of‑living adjustments (COLAs).
-
If you return to work or earn outside income after retirement, you may trigger an “earnings test.” Earning above a certain threshold can reduce — possibly wipe out — your supplement.
-
If you have at least 20 years of service and can work until 62, delaying retirement may yield a permanently higher FERS pension than combining a lower pension + supplement.
So, whether the supplement makes sense depends on your age, service years, financial needs, and desire (or need) to keep working.
Common Questions FERS Retirees Ask
Do I need to apply for it separately?
No — OPM automatically determines your eligibility when you apply for retirement.
Can I get Social Security and the supplement at the same time?
No. Once you hit age 62 and start Social Security, the supplement ends.
Does the supplement rise with inflation or COLAs?
No — unlike your main FERS pension, the supplement does not get cost‑of‑living adjustments.
What happens if I earn money after retirement?
OPM uses an “earnings test.” In recent years the exempt amount is updated annually. For every $2 you earn over the exempt threshold, your supplement is reduced by $1 — possibly to zero.
Should You Count on the Supplement? Smart Planning Tips
If you plan to retire early under FERS, treat the supplement as helpful — but not guaranteed income forever. Here’s how to make smart decisions:
-
Estimate early. Before you retire, check your Social Security projection (on SSA.gov) and calculate your likely supplement using the formula above.
-
Plan for earnings carefully. If you expect to work or have side income after retirement, project how that could reduce your supplement.
-
Compare to waiting until 62. If you can stay until 62 (especially with 20+ years of service), compare your monthly FERS pension with and without supplement — factoring in COLAs and potential pension bump.
-
Use it as a bridge, not a crutch. View the supplement as a short-term bridge to full retirement income, not a lifetime safety net.
What FERS & Postal Employees Should Do Now
If you’re covered by FERS and considering retirement, take these steps:
-
Log on to your Social Security account (SSA.gov) and get your age‑62 benefit estimate.
-
Plug in your years of FERS service into the supplement formula to project monthly benefit under the supplement.
-
Compare that with your basic FERS pension (and potential pension growth if you wait until 62).
-
If you expect to earn after retirement, estimate the earnings test effect.
-
Decide whether retiring early with supplement or staying till 62 makes sense.

Final Thought
The FERS annuity supplement can offer real help — especially if you retire before 62 and want predictable income until Social Security begins. But it isn’t permanent. It doesn’t grow with inflation, and it depends on your service years and future earnings.
If you plan carefully — understand your Social Security projection, estimate how supplement and pension compare, and account for income after retirement — you can make a solid, smart decision for your future.
Don’t guess. Calculate. Then make your move with confidence.
