FERS pension after 20 years, by high-3 and starting age
20 years at 1% replaces 20% of your high-3, or 22.0% at 62 and later at 1.1%. Monthly amounts before tax for someone born in 1970 or later (MRA 57); a cut marks the MRA+10 reduction for starting before 62.
| High-3 salary | At 57 (MRA) | At 60 | At 62 |
|---|---|---|---|
| $60,000 | $750 (25% cut) | $1,000 | $1,100 |
| $75,000 | $938 (25% cut) | $1,250 | $1,375 |
| $90,000 | $1,125 (25% cut) | $1,500 | $1,650 |
| $110,000 | $1,375 (25% cut) | $1,833 | $2,017 |
| $130,000 | $1,625 (25% cut) | $2,167 | $2,383 |
When you can retire with 20 years
With 20 years you can retire at 60 on an unreduced annuity with the FERS supplement until 62, or at your Minimum Retirement Age (57 if born 1970 or later) with a 5% cut for each year under 62. At 62 the multiplier rises to 1.1%.
Your Minimum Retirement Age depends on the year you were born, from 55 for people born before 1948 to 57 for 1970 and later:
| Born | MRA |
|---|---|
| 1952 | 55 and 10 months |
| 1953 to 1964 | 56 |
| 1965 | 56 and 2 months |
| 1966 | 56 and 4 months |
| 1967 | 56 and 6 months |
| 1968 | 56 and 8 months |
| 1969 | 56 and 10 months |
| 1970 or later | 57 |
The FERS supplement with 20 years
Retiring unreduced before 62 (at 60) adds the FERS supplement until 62: your Social Security estimate at 62 times 20 / 40. On a $2,000 estimate that is $1,000 a month, so $2,500 in all until 62. It is cut $1 for every $2 you earn above Social Security’s annual limit, and it stops at 62, when Social Security can start.
If you leave federal service with 20 years
Leaving before you are eligible to retire gives a deferred annuity: $1,500 a month from 62 on a $90,000 high-3. It always uses 1%, even at 62 with 20 years, does not count unused sick leave and pays no supplement. With 20 years it can also start at your MRA, cut 5% for each year under 62. Taking a refund of your contributions instead gives up the annuity.
After the survivor annuity
A married retiree takes a 50% survivor annuity unless the spouse consents to less. It costs 10% of the annuity and a 25% survivor annuity costs 5%. At 60 on a $90,000 high-3:
- No survivor annuity: $1,500 a month.
- 25% survivor annuity: $1,425 a month.
- 50% survivor annuity: $1,350 a month.
Regular FERS annuities get cost-of-living increases from 62. The annuity is taxed as ordinary income except the part that returns your contributions, and many states exempt some or all of it: see retirement taxes by state.

$90,000 × 20 years × 1% is $18,000 a year: $18,000 a year. Immediate annuity, not reduced for age. Cost-of-living increases start at 62.
Your MRA is 57. Add this annuity to the monthly retirement income calculator.
