If you've ever asked "when can I retire?" and gotten a different answer every time, it's because there isn't one. Unlike the private sector, where 65 or 67 is the default, FERS gives federal employees several doors to retirement — each defined by a specific combination of age and years of service. Walk through the right one and you get an immediate, unreduced annuity. Walk through the wrong one and you can forfeit 5% a year for the rest of your life. So the real question isn't "what age" — it's "which combination, and what does each one cost or pay?"
Your Minimum Retirement Age (MRA)
Everything starts with your MRA — the earliest age you can retire with an immediate annuity. It's set entirely by the year you were born, and it falls between 55 and 57. For most of today's workforce — anyone born in 1970 or later — it's a clean 57.
| Birth year | Minimum Retirement Age |
|---|---|
| Before 1948 | 55 |
| 1948–1952 | 55, plus 2 months per year |
| 1953–1964 | 56 |
| 1965–1969 | 56, plus 2 months per year |
| 1970 and later | 57 |
Reaching your MRA is necessary, but it isn't enough on its own. You also need a qualifying amount of service. That's where the four doors come in.
The four doors to an immediate retirement
To leave federal service and start your annuity right away, you have to meet one of these age-and-service combinations:
- MRA + 30 years — full, unreduced annuity, plus the FERS Supplement until age 62.
- Age 60 + 20 years — full, unreduced annuity, plus the FERS Supplement.
- Age 62 + 5 years — full, unreduced annuity (no supplement, because you're already eligible for Social Security).
- MRA + 10 years — you can leave immediately, but the annuity is reduced, and there's no supplement.
MRA + 30 — the early, unreduced door
This is the one most career federal employees aim for. If you reach your MRA with 30 years of creditable service, you can retire with a full annuity — no early-retirement penalty — and you'll receive the FERS Special Retirement Supplement to bridge your income until 62. For someone who started young, this can mean walking out the door at 57 with a full benefit.
Age 60 + 20 — full benefit a little later
If you don't have 30 years, reaching age 60 with 20 years still gives you a full, unreduced annuity and the supplement. This is the natural path for people who entered federal service mid-career.
Age 62 + 5 — the minimum door
Only 5 years of creditable service are needed to retire at 62 or later with a full annuity. There's no supplement here — at 62 you're already eligible for Social Security itself — but there's a different upside, covered below: the 1.1% multiplier.
MRA + 10 — the door with a toll
If you reach your MRA with at least 10 but fewer than 30 years, you can retire immediately under the MRA+10 provision. The catch: your annuity is reduced by 5% for every year you are under age 62. Retire at 57 under MRA+10 and that's a 25% permanent cut. There's also no FERS Supplement on this path.
Watch Out
MRA+10 is the most misunderstood category in FERS. People hear "I can retire at my MRA with 10 years" and assume it's a full benefit. It isn't — the 5%-per-year reduction is permanent, and it applies for the rest of your life, not just until 62.
Pro Tip
There's a way to dodge the MRA+10 reduction: postpone the start of your annuity. You separate from service at your MRA, but you delay drawing the annuity until a later age — which shrinks or eliminates the penalty. You can also keep your FEHB health coverage by paying premiums during the gap, then have it resume when the annuity begins. The math is worth running before you set a date.
The 1.1% multiplier: why age 62 can pay more
Your FERS pension is built from a simple formula:
The FERS pension formula
High-3 average salary × years of service × multiplier = annual pension
Your high-3 is the average of your highest 36 consecutive months of basic pay.
That multiplier is normally 1.0%. But if you retire at age 62 or later with at least 20 years of service, it jumps to 1.1% — a roughly 10% larger pension for the exact same career. Sometimes working a few extra months to land on the right side of that line is worth far more than it looks.
Retire at 60 with 30 years — $100,000 high-3
$100,000 × 30 × 1.0% = $30,000 / year
Full, unreduced — but the standard 1.0% multiplier.
Retire at 62 with 30 years — $100,000 high-3
$100,000 × 30 × 1.1% = $33,000 / year
Same service, $3,000 more every year — for life.
Special provisions: who can leave earlier
Some federal employees play by an earlier clock. Law enforcement officers (LEOs), firefighters, and air traffic controllers (ATCs) can retire at age 50 with 20 years of covered service, or at any age with 25 years. They also earn under an enhanced formula, and their FERS Supplement isn't touched by the earnings test until they reach their MRA — a meaningful break if they take a second career.
Separately, during a major reorganization or reduction in force, an agency may offer Voluntary Early Retirement (VERA), which opens the door at age 50 with 20 years, or any age with 25 — though an early-out annuity can come with its own reductions and trade-offs.
Federal Employee Note
The FERS Supplement that comes with the early doors (MRA+30 and 60+20) remains in effect for 2026. A 2025 proposal to eliminate it for future retirees passed the House but was removed by the Senate, so it did not become law. It's worth watching, since similar proposals can resurface — but as of now, nothing changes your eligibility.
Your date decides more than "when"
Choosing a retirement date isn't just picking a day on the calendar — it ripples through your entire benefit. It sets your pension multiplier (1.0% vs 1.1%), decides whether you receive the FERS Supplement, locks in your high-3, and even determines how your unused sick leave converts into extra service credit in the annuity formula. Two people with identical careers can end up with noticeably different incomes purely because of the dates they chose.
That's why the smartest move is to model it before you commit. The Stone Rose FERS Retirement Calculator shows your eligibility and your projected pension side by side, and it's the backbone of The Federal Employee's Financial Playbook — which walks through the timing decisions, FERS, TSP, FEHB, and Medicare coordination in plain language, written by someone who's navigated the system firsthand.
Frequently asked questions
What is the FERS Minimum Retirement Age (MRA)?
The earliest age you can retire with an immediate annuity. It's set by your birth year and ranges from 55 to 57 — anyone born in 1970 or later has an MRA of 57. Reaching it doesn't guarantee a full benefit; you also need enough years of service.
When can a federal employee retire with full, unreduced benefits?
At your MRA with 30 years, at age 60 with 20 years, or at age 62 with 5 years. Meeting any one of these three combinations avoids the early-retirement reduction.
Can I retire at my MRA with less than 30 years?
Yes — through MRA+10, if you have at least 10 years. But your annuity is reduced 5% for every year you're under 62, and it's permanent. You can avoid the cut by postponing your annuity start date. MRA+10 retirements don't receive the FERS Supplement.
What's the earliest a federal employee can retire?
For most, it's your MRA (55–57) with at least 10 years, though MRA+10 is reduced. Special-category employees — LEO, firefighter, ATC — can go at age 50 with 20 years, or any age with 25. VERA can also open the door at 50 with 20 or any age with 25 during a reorganization.
Does my retirement age affect my pension amount?
Yes. Your pension is high-3 × years × multiplier. The multiplier is 1.0%, but rises to 1.1% if you retire at 62+ with 20+ years — about 10% more for the same service. Retiring earlier also means fewer years in the formula.
