Federal Pension Value
Price your FERS or CSRS annuity as a lump sum in today’s dollars. Uses the statutory cost-of-living rules, the OPM Board of Actuaries assumptions and SSA life tables, and shows what the same income would cost to buy.

Gross, before the survivor reduction and before tax. If you do not know it, run the FERS or CSRS calculator first.
CSRS gets the whole index increase. FERS gets a trimmed one under 5 U.S.C. 8462(b), which is why the same dollar annuity is worth less under FERS.
SSA publishes separate columns. Your federal annuity itself is not priced by sex.
Default is 20.29 years from the SSA Period Life Table, 2023 (2026 Trustees Report). Edit it if you want to plan to a specific age.
Defaults are the OPM Board of Actuaries assumptions used to value the Civil Service Retirement and Disability Fund: 4 percent interest and 2.4 percent inflation. For a market rate instead, the 20-year Treasury was 5.67 percent on 2026-10-02.
| Discount rate | Present value | Change |
|---|---|---|
| 3.0% | $766,857 | +$63,974 |
| 4.0% (yours) | $702,883 | no change |
| 5.0% | $646,744 | -$56,139 |
| Modeled | Not modeled |
|---|---|
| The FERS cost-of-living brackets in 8462(b)(1), including the behaviour at exactly 3 percent | Year-to-year variation in inflation. One constant assumption is applied to every year |
| The under-62 suppression in 8462(c)(3), with the special provision exceptions as a toggle | The month-by-month proration of the first year’s adjustment under 8462(c)(1) |
| The full index increase for CSRS under 8340(b) | The rounding of each monthly installment down to the dollar under 8462(d) |
| The survivor reductions in 8419(a) for FERS and 8339(j)(4) for CSRS | The value of the survivor annuity itself. This prices the retiree’s own stream only |
| A yearly payment stream valued as an annuity-due, so the first year is not discounted | Monthly discounting. Federal annuities pay monthly and adjust once a year, and annual steps track that within about 1 percent |
| SSA period life table defaults, with interpolation between published ages flagged in the form | Future mortality improvement, joint life expectancy, and your own health |
| A sensitivity table one point either side of your discount rate | Tax. The annuity is taxable income and the present value shown is pre-tax |
Precision limit: a present value is only as good as its assumptions, and reasonable people pick different ones. Treat the sensitivity table as the real answer and the single headline figure as its midpoint. The life expectancy default is a period table, which reads short for someone retiring today and biases the value low.
The diet cost-of-living rule is the whole story
Two retirees, same salary, same years, same age. One is CSRS and one is FERS. The CSRS annuity is worth noticeably more per dollar of payment, and the reason is one sentence of statute. CSRS gets the whole index increase. FERS gets the lesser of the increase or 2 percent when prices rise 3 percent or less, and the increase minus a point when they rise faster.
OPM's actuaries put a number on the gap. Their long-term assumption is 2.40 percent inflation and a 1.92 percent FERS adjustment, and they say in the report that the second figure is 80 percent of the first. Over a 25-year retirement, losing a fifth of your inflation protection every year compounds into a materially smaller stream.
Retiring before 62 costs more than the age reduction
A regular FERS retiree who leaves at 57 gets no cost-of-living increase until 62. Five frozen years do not sound severe, but they lower the base that every later increase builds on, so the loss never gets made up. Tick the special provision box on the form and the same inputs produce a visibly larger present value, which is the cleanest way to see what those five years are worth.
What the pension is worth against what it would cost
The purchase price shown next to the present value comes from published commercial payout rates, and it is deliberately unflattering to the insurer. Those contracts pay a flat amount forever, with no inflation protection, and they charge women more because they live longer. Your federal annuity rises with prices and is priced the same for everyone. If replacing a level annuity already costs that much, replacing an indexed one costs more.
