USPS Retirement Date Calculator
USPS career employees retire under FERS. Enter your birth date and postal service start date to get your minimum retirement age and your earliest date under each FERS eligibility combination — the same official rules as other federal employees.
How it's calculated
Postal career employees are covered by FERS, so this tool uses the FERS rules: your birth year sets your minimum retirement age (MRA, 55–57), and each of the four combinations needs both its age and its service — the date shown is whichever comes later. MRA + 10 years gives a reduced annuity; the other three are unreduced.
Dates only — no annuity amounts. FERS MRA, explained.
Examples
Born 15 March 1980, postal service started 1 June 2005 (FERS; MRA 57 years):
| Combination | Earliest date |
|---|---|
| MRA with 30 years of service | 15 March 2037 (Sunday) |
| Age 60 with 20 years of service | 15 March 2040 (Thursday) |
| Age 62 with 5 years of service | 15 March 2042 (Saturday) |
| MRA with 10 years of service (reduced) | 15 March 2037 (Sunday) |
USPS retirement: what to know
- You're FERS. Since 1984, postal career employees have been under the Federal Employees Retirement System — the same eligibility rules as other federal workers, applied here.
- Hired before 1984? You may be under CSRS instead, a separate system this tool doesn't cover.
- Part-time and non-career time can affect creditable service. Use your creditable service start date — your HR or personnel records have it.
- Special provisions (law enforcement-style roles within USPS, e.g. postal inspectors in covered positions) use different rules and aren't covered here.

Frequently asked questions
Do postal workers really use FERS?
Yes — career USPS employees hired from 1984 onward are covered by FERS, the same system as other federal employees. That's why the eligibility dates here match the FERS calculator.
What service start date should I enter?
Your creditable-service start date — usually your career appointment date. Non-career time (casual, TE, early RCA stints) generally doesn't count unless you bought it back. Check your personnel records if unsure.
I'm a rural carrier / city carrier — any difference?
Not for the eligibility dates: craft doesn't change the FERS age-and-service combinations. What differs is how your annuity is computed — a benefits question this site doesn't touch.
What does "reduced" mean for MRA + 10?
The annuity is permanently reduced for each month you're under 62 when it starts. Postponing the start date to 62 can avoid the reduction.
Does this cover CSRS?
No. CSRS covers employees hired before 1 January 1984 and has its own rules. If that's you, OPM's CSRS materials are the right source.
