Understanding FERS Retirement Eligibility: MRA, MRA+10, and 60/20

One of the most common questions federal employees ask is: when am I eligible to retire? The answer depends on your age, years of creditable service, and which FERS eligibility path you qualify for.

This guide breaks down the three main paths to an immediate FERS retirement — and what each one means for your pension, supplement, and overall financial picture.

The three main eligibility paths

FERS offers three primary paths to an immediate (unreduced) retirement. Each has different age and service requirements, and each affects your benefits differently.

1. MRA + 30 years of service

This is the earliest path to a full, unreduced FERS pension. Your minimum retirement age (MRA) depends on your birth year:

• Born before 1948: MRA is 55
• Born 1948–1952: MRA increases by 2 months per year (55 and 2 months through 55 and 10 months)
• Born 1953–1964: MRA is 56
• Born 1965–1969: MRA increases by 2 months per year
• Born 1970 or later: MRA is 57

With MRA + 30 years, you receive your full pension with no reduction, and you are eligible for the FERS supplement (which bridges the gap until Social Security kicks in).

2. Age 60 + 20 years of service

If you reach age 60 with at least 20 years of creditable service, you can retire with an unreduced pension. This is straightforward — no MRA lookup needed.

One important difference: at age 60, you are not eligible for the FERS supplement. The supplement is only available to those who retire at MRA with 30+ years of service (or under certain involuntary/early retirement provisions).

3. MRA + 10 years of service (reduced pension)

This is the earliest you can retire voluntarily under FERS, but it comes with a permanent pension reduction: 5% per year (5/12% per month) for each year you are under age 62.

For example, if your MRA is 57 and you retire at 57 with 15 years of service, your pension is permanently reduced by 25% (5 years × 5%). That reduction never goes away — it applies for the rest of your life.

You are also not eligible for the FERS supplement under MRA+10.

How this connects to your planning

Eligibility is just the starting point. The real question is whether the income picture works — what your pension, supplement, TSP withdrawals, Social Security, and taxes actually look like month to month after you stop working.

That is exactly what FERSCalc is built to help you figure out. You can open the calculator and compare different retirement dates side by side to see how timing affects your projected cash flow.

Special cases

The rules above cover standard FERS employees. There are additional provisions for:

• 6C special-category employees (law enforcement officers, firefighters, air traffic controllers): eligible at age 50 with 20 years of covered service, or at any age with 25 years
• VERA (Voluntary Early Retirement Authority): available during agency restructuring, allowing retirement at age 50 with 20 years, or any age with 25 years
• Disability retirement: separate eligibility rules requiring 18 months of service
• Deferred retirement: if you leave federal service before meeting age requirements but have at least 5 years of creditable service

FERSCalc currently supports standard FERS tiers and 6C special-category retirement. For other special cases, consult your HR office or benefits specialist.
