FERS minimum retirement age

The Minimum Retirement Age (MRA) is the earliest age at which a FERS employee can retire and receive an immediate annuity. It is set by statute and depends solely on your birth year — not your years of service, pay grade, or agency.

MRA is distinct from Social Security's early retirement age (62) and from Medicare eligibility (65). It is purely a FERS concept that governs when you can separate from federal service and begin receiving your FERS pension.

Reaching your MRA does not automatically mean you should retire. Whether it makes sense to retire at MRA depends on your years of service, the pension reduction rules that apply, what you would lose in benefits, and what you would gain in time. This guide walks through each scenario.

MRA was introduced when FERS replaced CSRS in 1987. Under the old CSRS system, employees could retire at age 55 with 30 years of service or at any age with 30 years if under certain early-out authorities. FERS tightened these rules and created a sliding-scale MRA to reflect longer average career lengths.

Your MRA is determined entirely by your birth year. The table below shows every birth year cohort and the corresponding MRA:

The most common MRA for the current active federal workforce is 57 (anyone born in 1970 or later). Employees born between 1953 and 1964 have an MRA of exactly 56. The transitional cohorts (1948–1952 and 1965–1969) have fractional MRAs that add months beyond the whole number.

Example: If you were born in March 1975, your MRA is 57. You reach your MRA in March 2032. If you have 30 or more years of service at that point, you can retire with full benefits. If you have 10–29 years, you can retire with a reduced pension.

FERS has three primary retirement pathways. MRA is central to two of them:

The MRA+30 pathway is typically the most valuable option for employees who can reach it: no pension reduction, the annuity supplement (which approximates Social Security until 62), and continued FEHB coverage. For an employee born in 1975 with an MRA of 57, reaching MRA+30 requires starting federal service by age 27.

The Age 60+20 pathway is a powerful option for mid-career entrants who joined the federal government after age 40. At age 60 with 20 years of service, you qualify for the same full benefit as MRA+30 — including the supplement and FEHB.

The Age 62+5 pathway gives you the highest pension multiplier (1.1% vs. 1.0%) if you have at least 20 years of service at 62. It does not include the annuity supplement (which ends at 62 for MRA+30 retirees anyway).

MRA+10 allows you to retire at your MRA (as early as 56 or 57 for most current employees) with as few as 10 years of creditable service. The catch: your pension is reduced by 5% for every year you are under age 62 at the time you start collecting.

The reduction is calculated as: (62 − your age at retirement start) × 5%.

This reduction is permanent. It does not phase out when you turn 62 — it stays for the rest of your life. COLA adjustments (which begin at 62 for FERS retirees) apply to the already-reduced amount.

MRA+10 retirees do not qualify for the FERS Annuity Supplement. They also must have met the 5-year FEHB enrollment rule to keep federal health insurance in retirement. For most employees, the combination of no supplement and a 25–30% pension cut makes MRA+10 an option of last resort — useful primarily for those who genuinely need to leave federal service at MRA but cannot yet reach the 30-year threshold.

A little-known option within MRA+10 is postponed retirement. Instead of starting your annuity immediately when you separate, you can leave federal service at MRA and defer the start of your annuity to a later date — reducing or eliminating the 5%/year penalty.

How it works: You separate from federal service at your MRA. You do not submit a retirement application right away. Instead, you notify OPM of your deferred start date. Your annuity starts later — and is reduced only for the years you are under 62 when it starts, not for the years between separation and annuity start.

Example: You have an MRA of 57 and 15 years of service. If you start your annuity at 57, you take a 25% reduction. If you postpone to age 60, you take a 10% reduction. If you postpone to age 62, you take no reduction at all.

The FEHB gap: This is the major trade-off of postponed retirement. If you delay your annuity start date, your FEHB coverage is suspended during the gap. You cannot keep FEHB from your retirement date to your annuity start date — you would need to find alternative health coverage (ACA Marketplace, COBRA via TCC, or a spouse's plan) for that period. When your annuity does start, FEHB reinstates — but you must have already met the 5-year enrollment rule at the time you separated.

Postponed retirement makes most sense for employees who have private-sector income or a spouse's insurance to bridge the gap, and who want to minimize the long-term pension reduction.

Retiring under MRA+30 — reaching your MRA with at least 30 years of creditable service — is the most advantageous early retirement scenario in FERS. You receive:

• An immediate, unreduced pension at the full 1.0% multiplier (or 1.1% if you reach this milestone at age 62 or older)
• FEHB in retirement — the government health insurance subsidy continues for life
• The FERS Annuity Supplement — an additional monthly payment that approximates Social Security until you turn 62
• COLA adjustments beginning at age 62

For an employee born in 1975 (MRA 57), reaching MRA+30 requires 30 years of creditable service by age 57. That means starting federal service — with no breaks — by age 27. Military buyback can count toward the 30 years if the military service deposit is paid.

What "30 years of creditable service" includes: civilian FERS service, military service with a paid deposit, prior federal civilian service under CSRS or another retirement system (if not refunded), and sick leave balances at retirement (which are added to your service total for pension calculation purposes, though not for retirement eligibility).

The annuity supplement at MRA+30 can be substantial. Using the formula (Estimated Social Security at 62 × FERS years ÷ 40), a 30-year retiree with an estimated $24,000/year Social Security benefit at 62 would receive a supplement of $18,000/year — that's $1,500/month in additional income from retirement to age 62.

The choice between retiring at MRA (say, 57) versus waiting until 62 is one of the most significant financial decisions in FERS planning. Both ages can lead to an unreduced pension — if you have the service time — but the outcomes differ in several important ways:

In this example, retiring at 57 gives you 5 more years of retirement and the supplement, but a lower pension. Retiring at 62 gives you a substantially higher pension for a shorter period. The lifetime break-even depends on how long you live, your discount rate, and what the supplement is worth to you.

Use the retirement timing calculator to model your specific numbers. It calculates the total lifetime pension value at every possible retirement age and year, so you can see exactly where the crossover point is for your situation.

Certain federal employees in physically demanding or hazardous jobs are classified as "special category" or "enhanced FERS" employees and have different retirement eligibility rules. These include:

• Law Enforcement Officers (LEOs) — federal agents, Border Patrol, DEA, FBI, ATF, and similar
• Firefighters — federal civilian firefighters
• Air Traffic Controllers (ATCs)
• Nuclear materials couriers
• Capitol Police, Supreme Court Police
• Customs and Border Protection Officers (CBPOs)

Standard special category retirement: Age 50 with 20 years of covered service, or at any age with 25 years of covered service. No MRA requirement.

Pension multiplier: 1.7% per year for the first 20 years of covered service, 1.0% for additional years. This is significantly more generous than the standard FERS 1.0% multiplier.

Mandatory separation: Many special category employees face mandatory retirement ages — typically 57 for LEOs and firefighters, 56 for ATCs. These are not optional; federal law requires separation at those ages.

If you are a special category employee, the MRA tables in this guide do not apply to you in the same way. Your agency's HR office and the applicable statute govern your specific retirement eligibility.

Finding your MRA is straightforward — look up your birth year in the table above. What requires more careful research is your Service Computation Date (SCD), which is the date used to calculate your years of creditable service.

Your SCD is printed on your most recent SF-50 (Notification of Personnel Action) in Box 31. It may differ from your actual hire date for several reasons:

• Military service buyback: If you have active duty military service and paid the deposit, your SCD is adjusted backward to credit that time.
• Prior federal civilian service: Previous periods of federal employment may be counted if the service was not refunded.
• Part-time service: Part-time service is credited at the actual hours worked, which can reduce your effective service credit.
• Non-deduction service: Some older federal service performed before FERS without retirement contributions may be credited at a reduced rate.

Request an unofficial service computation estimate from your agency's HR office or review your SF-50 history in your eOPF (electronic Official Personnel File). For an official count, contact OPM or request a retirement estimate through your agency's HR system.

Once you know your SCD and your MRA birth year, enter both into the FERS estimator to see your retirement income projections for every possible departure year — including the exact age at which you reach each milestone.
