Look up your FERS Minimum Retirement Age by birth year and see the calendar date you reach it.

Minimum Retirement Age, defined: The MRA is the earliest age at which a FERS employee can retire on an immediate annuity — provided they also meet a service requirement. It ranges from 55 (born before 1948) to 57 (born 1970 or later). MRA is a gate, not a benefit: what it opens depends entirely on your years of service.

Who This Article Is For

• FERS employees who aren't sure whether their MRA is 56-and-change or 57
• Feds in the 1965–1969 birth years, where the MRA moves in 2-month steps and online answers are usually wrong
• Employees planning around MRA+10 vs. MRA+30 and the very different retirements they produce
• Anyone who has conflated MRA with Social Security age, TSP withdrawal age, or Medicare age (they're four different numbers)
• Federal couples comparing timelines when spouses have different birth years

1. The MRA Table: Find Your Birth Year

The MRA was designed to drift upward alongside Social Security's full retirement age. The exact schedule:

Reference table from OPM regulations. MRA is determined by your birth year. Confirm your specific MRA with OPM or your agency HR office.

Most of today's workforce lands on the bottom row: born 1970 or later → MRA is exactly 57. The 1965–1969 cohort — now in their late 50s and actively planning — are the ones who need the precise month. Born in August 1967? Your MRA is 56 years 6 months, reached in February 2024. The MRA Finder computes the calendar date from your date of birth.

Note what the MRA is not tied to: your hire date, your years of service, or your agency. Birth year only. (Special-category employees — law enforcement, firefighters, air traffic controllers — have their own earlier retirement thresholds at 50/20 or any-age/25 that don't run through the MRA at all.)

2. What Reaching MRA Actually Unlocks

MRA is one input to a two-part test: age + service. Here's the full FERS immediate-retirement eligibility map, with MRA rows highlighted in context:

Read that table top-to-bottom and the MRA's real meaning emerges:

• MRA+30 is the headline event. Full career, full annuity, and the FERS Supplement bridging you to 62. For a born-1970-or-later fed hired at 27 or earlier, age 57 is the first day full retirement is possible.
• MRA+10 is the emergency exit, not the plan. It works — the annuity is immediate — but the 5%-per-year reduction is permanent, and there's no supplement. The smarter use of MRA+10 is often the postponed variant, which shrinks the penalty and preserves FEHB; that decision has its own trade-offs, covered in our Deferred vs. Postponed guide.
• MRA with fewer than 10 years unlocks nothing immediate. You'd be looking at a deferred annuity at 62 like any other separated employee with 5+ years.

One more quiet role the MRA plays: if you separate mid-career with 30+ years, your deferred annuity can begin — unreduced — at your MRA rather than 62.

3. The Four Ages People Confuse with the MRA

Federal retirement planning involves at least four different "magic ages," and mixing them up is the most common planning error we see:

The TSP row deserves emphasis because it cuts the other way: if you work until your MRA (57) and then retire, your TSP is immediately accessible without penalty — the IRS age-55 separation rule is already satisfied. Feds sometimes assume TSP is locked until 59½ regardless; for retirees who separate at 55 or later, it isn't.

4. Worked Timeline: Born 1970, Hired at 25

Illustrative example. One birth year, one hire date, standard (non-special-category) coverage. Your milestones shift with your own dates — the FedHorizon Timeline maps them from your actual inputs. Not financial advice.

Notice the decision compression at 62: the supplement cliff, the Social Security claim decision, and the 1.1%-multiplier question ("is working to exactly 62 worth 10% more pension?") all land in the same year. That's why our retire-at-57-vs-62 analysis treats those two ages as the pivotal comparison for most FERS careers.

5. Common MRA Mistakes

1. Rounding 56-and-months to 56. For the 1965–1969 cohort, retiring even one month before the true MRA date means you haven't met MRA+30 or MRA+10 at all — the retirement category simply isn't available yet.
2. Treating MRA as sufficient by itself. MRA with 8 years of service is just an age. The service prong (10 or 30 years) does equal work.
3. Using MRA+10 casually. The 5%/year reduction is permanent and the supplement is forfeited. It's a real option with real costs — model it before relying on it.
4. Forgetting sick leave doesn't help eligibility. Unused sick leave adds to your annuity computation, never to the service years used for the MRA+30 or MRA+10 tests.
5. Planning TSP access around 59½. If you retire at your MRA (55+), the age-55 separation rule already applies — no need to bridge to 59½.

Frequently Asked Questions

What is the FERS Minimum Retirement Age? Between 55 and 57 depending on birth year: 55 for those born before 1948, 56 for 1953–1964, 57 for 1970 and later, with 2-month gradations in the transition years (1948–1952 and 1965–1969).

What is the MRA if I was born in 1970 or later? Exactly 57. This covers the large majority of the current federal workforce.

Born 1965–1969 — what's my MRA? 56 plus 2 months for each year after 1964: 1965 → 56y2m, 1966 → 56y4m, 1967 → 56y6m, 1968 → 56y8m, 1969 → 56y10m.

Can I retire at my MRA? Only with enough service: 30+ years gives an immediate unreduced annuity plus the FERS Supplement; 10–29 years gives an immediate but reduced (MRA+10) annuity. Fewer than 10 years — no immediate retirement.

What is MRA+10? The provision letting you retire at your MRA with 10–29 years of service, at a 5%-per-year-under-62 reduction. The reduction can be shrunk or eliminated by postponing the annuity start date.

Does reaching MRA get me the FERS Supplement? Only if you retire under MRA+30 (or 60/20). MRA+10 retirees never receive the supplement, and it ends for everyone at 62.

Is the MRA the same as Social Security retirement age? No. The MRA (55–57) governs FERS eligibility only. Social Security has its own ages: 62 earliest, 67 full retirement age for those born 1960+, 70 for maximum delayed credits.

Can I access my TSP at my MRA? If you separate at your MRA, yes — anyone separating from service in or after the year they turn 55 can withdraw TSP without the 10% early-withdrawal penalty (age 50 or 25 years of service for special-category employees under SECURE 2.0 rules).

Does military or bought-back service count toward MRA+30? Bought-back military service counts toward the 30-year service requirement, yes — see the military buyback guide. Your MRA itself never changes; only the service side of the test moves.

The Bottom Line

The MRA is the most misquoted number in federal retirement, and it's a simple table lookup: 57 for anyone born 1970 or later, a birth-month calculation for the transition cohorts. Its meaning is just as crisp — a gate that opens onto a full unreduced retirement if you bring 30 years to it, a costly-but-real early exit if you bring 10, and nothing at all by itself. Find your exact date, put your service years next to it, and the shape of your earliest possible retirement stops being folklore and becomes arithmetic.
