The average federal pension: what FERS actually pays
“What does the average federal pension pay?” is one of the most-asked questions by feds and the public alike — and the honest answer surprises people in both directions. The average FERS annuity is about $2,126 a month, far less than the legendary CSRS checks of $5,000+. But that comparison is misleading: FERS was designed to be smaller because it’s only one leg of a three-legged stool that also includes Social Security and the TSP. This guide breaks down the real numbers, the formula behind them, what the typical retiree looks like, and how to read your own pension in context — with a calculator to estimate yours against the average.
1. The headline number
Per OPM data analyzed by the Congressional Research Service, the average monthly annuity for FERS retirees is about $2,126; for CSRS retirees it’s about $5,447 — a gap of roughly $3,300 a month. New FERS retirees in a recent year averaged closer to $1,982/month. Those are averages; your own number depends entirely on your salary and years of service.
A $2,126 average pension sounds alarming next to a $5,447 CSRS check — but it’s comparing a third of one retirement system to the whole of another. FERS retirees also collect Social Security and draw on a matched TSP. The pension is built to be smaller on purpose.
2. Why FERS is smaller than CSRS
CSRS (closed to new entrants in 1984) was a single, large stand-alone pension — but CSRS employees generally earn no Social Security from their federal work and got no TSP match. FERS replaced that with a three-part design:
| System | Pension | Social Security | TSP match |
|---|---|---|---|
| CSRS | Large (~2% / yr) | No (from fed service) | None |
| FERS | Smaller (1–1.1% / yr) | Yes | Up to 5% |
So the smaller FERS annuity isn’t a worse deal — it’s a different structure. Today ~98% of current federal employees are under FERS; CSRS is fading out.
3. The formula
The basic FERS annuity is straightforward:
If you retire at 62+ with 20+ years → 1.1% instead of 1%
Your high-3 is the highest average basic pay over any three consecutive years (usually your last three). The 1.1% “kicker” for retiring at 62+ with 20+ years is a ~10% boost — one reason staying to 62 can pay off. Unused sick leave adds to your service time in the computation. See the full mechanics in FERS pension calculation.
4. The average retiree
What does the typical federal retiree actually look like? Per OPM, the average civilian who retired recently was about 62 years old with roughly 25 years of service. Run that through the formula: 25 years × 1% = 25% of high-3. On a $90,000 high-3, that’s about $22,500/year, or ~$1,875/month — right in line with the new-retiree average. The retirees pulling $5,000+ pensions are overwhelmingly long-service CSRS holders (averaging 40+ years) or special-provision retirees with enhanced formulas.
5. Estimate your annuity
Enter your high-3, your years of service, and your planned retirement age. The calculator applies the right multiplier (including the 1.1% kicker) and compares your estimate to the FERS average.

6. The three-legged stool
FERS only makes sense as part of a whole:
- Leg 1 — the annuity (~$2,126 average): the guaranteed, COLA-adjusted base.
- Leg 2 — Social Security (~$2,000/month average): FERS employees pay in and collect it.
- Leg 3 — the TSP: with the 5% match, a full-career saver can build a balance that throws off more than the pension itself. (The median FERS TSP balance is modest, ~$50K, but disciplined savers reach far higher.)
Stack all three and a FERS retiree can land near the same total income as a CSRS retiree — the pension just looks smaller on its own line.
7. The replacement-rate reality
The pension replaces roughly 1% of your high-3 per year of service — so 25 years ≈ 25%, 30 years ≈ 30%, 40 years ≈ 40%. Most planners target 70–80% income replacement in retirement, which is exactly why FERS leans on Social Security and the TSP to fill the rest. If you’re relying on the annuity alone, the math won’t reach a comfortable replacement rate; see how much you need to retire.
8. The diet-COLA drag
One reason the FERS pension loses ground to CSRS over time is the FERS “diet COLA”: when CPI-W runs 2–3%, FERS retirees get a flat 2.0% instead of the full CPI that CSRS and Social Security receive. For 2026 that was 2.0% for FERS vs. 2.8% for CSRS/SS. Most FERS retirees under 62 get no COLA at all until 62 (with disability/survivor/special-provision exceptions). Over a 25-year retirement, that 0.8-point annual lag compounds into a meaningful purchasing-power gap — the gap the proposed Equal COLA Act aims to close.
9. Frequently asked questions
What is the average federal pension?
According to OPM data analyzed by the Congressional Research Service, the average monthly annuity for workers who retired under FERS was about $2,126, while the average for the older CSRS system was about $5,447. New FERS retirees in a recent year averaged closer to $1,982 a month, having retired around age 63 with roughly 24 years of service. The gap between FERS and CSRS is by design: FERS pays a smaller pension because FERS employees also earn Social Security and receive employer matching in the Thrift Savings Plan, whereas CSRS was a stand-alone pension with no Social Security from federal service and no TSP match.
How is the FERS pension calculated?
The basic FERS annuity equals 1 percent of your high-3 average salary multiplied by your years of creditable service. The high-3 is the highest average basic pay over any three consecutive years, usually your final three. If you retire at age 62 or later with at least 20 years of service, the multiplier rises to 1.1 percent instead of 1 percent, a roughly 10 percent boost to the pension. So 30 years of service generally yields about 30 percent of your high-3 (or 33 percent at the 1.1 percent rate). Unused sick leave adds to your service time in the computation but cannot be used to meet eligibility.
Why is the FERS pension so much smaller than CSRS?
It was deliberately designed that way. CSRS, which closed to new entrants in 1984, was a single large pension, and CSRS employees generally do not earn Social Security from their federal work and got no government TSP match. FERS replaced it with a three-part structure: a smaller defined-benefit annuity, Social Security, and a Thrift Savings Plan with up to 5 percent agency matching. The smaller FERS annuity is only one leg of three. When you add a FERS retiree's Social Security and TSP withdrawals, total retirement income can be comparable, but the pension portion alone looks far smaller than a CSRS check.
What percentage of my salary will the FERS pension replace?
The FERS annuity alone replaces a relatively modest share of pre-retirement pay, roughly 1 percent of your high-3 for each year of service. A 25-year career replaces about 25 percent of your high-3, and a 30-year career about 30 percent (or 33 percent if you qualify for the 1.1 percent multiplier at 62 with 20-plus years). That's why FERS is meant to be combined with Social Security and the TSP. Most planners target roughly 70 to 80 percent income replacement in retirement, and for FERS employees the pension is designed to be one of three legs reaching that goal, not the whole stool.
Does the FERS pension get a cost-of-living adjustment?
Yes, but a reduced one known as the diet COLA. When inflation as measured by the CPI-W runs between 2 and 3 percent, FERS retirees receive a flat 2.0 percent, less than the full CPI that CSRS and Social Security receive. For 2026 that meant a 2.0 percent FERS COLA versus 2.8 percent for CSRS and Social Security. In addition, most FERS retirees under age 62 do not receive any COLA at all until they reach 62, with exceptions for disability, survivor, and special-provision retirees. Over a long retirement, the diet COLA lag compounds and erodes purchasing power relative to CSRS.
