FERS Minimum Retirement Age Chart: Eligibility by Birth Year

Your MRA Depends on When You Were Born

Under the Federal Employees Retirement System, you don't automatically qualify for retirement at a fixed age the way Social Security works. Your Minimum Retirement Age (MRA) is set by your birth year, and it determines the earliest point at which certain retirement pathways open to you.

Here's the complete chart:

For the majority of federal employees approaching retirement today (born between 1953 and 1970), the MRA falls between 56 and 57. The exact month matters when you're planning your separation date — retiring one month before reaching your MRA changes which benefit pathways are available.

The Three Paths to an Immediate Unreduced Annuity

Your MRA alone doesn't determine eligibility. FERS retirement works on age-plus-service combinations. There are three paths to an immediate annuity with no age-related reduction:

Path 1: MRA + 30 Years of Service

Reach your MRA with at least 30 years of creditable service, and you qualify for an immediate, unreduced annuity. You also qualify for the Special Retirement Supplement (SRS), which bridges the gap between your FERS annuity and Social Security eligibility at age 62.

This is the most common path for career federal employees who entered service in their mid-to-late twenties.

Path 2: Age 60 + 20 Years of Service

If you reach age 60 with at least 20 years of creditable service, you qualify for an immediate, unreduced annuity and the SRS. Your MRA is irrelevant in this scenario — age 60 is the threshold regardless of your birth year.

This path works well for employees who entered federal service later in their careers — perhaps after military service, private sector work, or a mid-career switch.

Path 3: Age 62 + 5 Years of Service

At age 62, you need only five years of creditable service for an immediate, unreduced annuity. This is the minimum-service pathway and comes with a bonus: if you have 20 or more years of service at age 62, your annuity accrual factor increases from 1.0% to 1.1% per year.

The SRS does not apply at age 62 or later — by that point, you're eligible for actual Social Security benefits, which the supplement was designed to approximate.

The MRA+10 Option and Its Cost

There's a fourth path that gets less attention: reaching your MRA with at least 10 years of service (but fewer than 30). This qualifies you for an immediate annuity, but it comes with a permanent reduction of 5% for each year you're under age 62 at the time payments begin.

For a 56-year-old with an MRA of 56 and 15 years of service, that's a 30% permanent reduction (6 years × 5%). On an annuity that would otherwise be $1,500 per month, the reduction cuts it to $1,050 — for life.

Postponing to Avoid the Penalty

You can avoid or reduce the MRA+10 penalty by separating from service at your MRA but delaying the start of your annuity payments. This is called a "postponed retirement":

• Postpone until age 60 with 20 years of service: The reduction is eliminated entirely, and you can reinstate FEHB and FEGLI coverage when payments begin (provided you met the five-year enrollment requirement at separation).
• Postpone until age 62: The reduction is eliminated entirely regardless of years of service.

The trade-off is clear: you give up years of annuity income in exchange for a higher monthly payment for the rest of your life. Whether postponement makes financial sense depends on your other income sources, health insurance options during the gap, and how long you expect to receive the annuity.

Deferred Retirement Is Different

A deferred retirement applies to employees who leave federal service before reaching their MRA. They can claim an annuity later (at age 62 with 5 years of service, or at their MRA with 10+ years), but deferred retirees are permanently ineligible to reinstate FEHB and FEGLI coverage. Postponed retirement preserves that eligibility; deferred does not. The distinction matters enormously for health insurance planning.

Calculate Your Annuity

The basic FERS annuity formula is:

1.0% × High-3 Average Salary × Years of Creditable Service

If you retire at age 62 or later with 20+ years of service, the multiplier increases to 1.1%. The high-3 is your highest average basic pay over any three consecutive years — usually the last three years of service for most employees.

Unused sick leave also counts toward creditable service for the annuity calculation (though not for retirement eligibility). Every 2,087 hours of sick leave equals one year of additional creditable service in the formula.

Put Your Numbers Together

The FERS Retirement Application Guide includes an eligibility verification worksheet and an annuity estimation walkthrough that takes you through the exact calculation using your service computation date, high-3 salary, and sick leave balance.
