What Does FRA Mean in Social Security: Full Retirement Age

In Social Security, FRA stands for Full Retirement Age: the age at which you qualify for 100% of your retirement benefit, known as your Primary Insurance Amount. Claim before that age and your monthly check is permanently reduced. Wait past it and your check permanently grows, up to age 70. FRA also sets the baseline for spousal and survivor benefits, controls whether wages from work reduce your payments, and marks the point where Social Security Disability Insurance converts to retirement.

Your Primary Insurance Amount is calculated from your 35 highest-earning years, adjusted for wage inflation and run through a tiered formula.¹ At FRA, that figure is what lands in your account each month, with no early-claiming haircut and no delayed-claiming bonus.

Your FRA Depends on the Year You Were Born

FRA isn’t a single age for everyone. It phases up from 66 to 67 based on birth year:²

1943–1954: age 66
1955: 66 and 2 months
1956: 66 and 4 months
1957: 66 and 6 months
1958: 66 and 8 months
1959: 66 and 10 months
1960 or later: age 67

Anyone still making a claiming decision in 2026 who was born in 1960 or later has an FRA of 67. That’s the number most current retirees are working with.

Claiming Before Your FRA

You can start retirement benefits as early as age 62, but every month you claim before FRA cuts your monthly payment permanently.³ The reduction doesn’t disappear later. It sticks for life, with only annual cost-of-living adjustments applied on top.

The formula runs on two tiers. For each of the first 36 months before your FRA, your benefit drops by five-ninths of 1%. For any month beyond those 36, the rate is five-twelfths of 1%.³ Someone with an FRA of 67 who files at 62 is claiming 60 months early. That works out to a 30% reduction. A $2,000 full benefit becomes $1,400.⁴

Claiming After Your FRA

Wait past FRA and your benefit grows through delayed retirement credits. For anyone born in 1943 or later, that’s two-thirds of 1% for each month you delay, or 8% a year.⁵ Credits stop at age 70. Waiting past 70 gains you nothing.

A worker with an FRA of 67 who delays to 70 picks up three full years of credits, a 24% increase over the Primary Insurance Amount. On a $2,000 PIA, that’s $2,480 a month for life.⁶

If you’ve already passed your FRA when you file, you can request up to six months of retroactive benefits paid as a lump sum. Doing so shifts your effective start date back by that many months, which means slightly fewer delayed credits going forward.⁵ Retroactive benefits aren’t available before FRA.

Working While Collecting Before FRA

If you claim early and keep working, wages above a set limit trigger the retirement earnings test. This catches a lot of early filers off guard.

In 2026, if you’re under FRA for the whole year, you can earn up to $24,480 with no impact. Above that, Social Security withholds $1 for every $2 you earn over the limit. In the year you reach FRA, the limit for the months before your birthday jumps to $65,160, and the withholding rate drops to $1 for every $3 over the limit.⁷ Once you actually hit your FRA month, the earnings test ends. You can earn any amount with no reduction.

Money withheld under the earnings test isn’t lost. When you reach FRA, Social Security recalculates your benefit to credit you for the withheld months, and your ongoing payment goes up.⁸ It isn’t a dollar-for-dollar refund, but it does recover the withholding over time. Social Security also reviews your earnings each year and raises your benefit if a recent year of wages replaces a lower one in your top 35.⁹

How FRA Shapes Spousal Benefits

FRA also sets the maximum for benefits claimed on a spouse’s record. The full spousal benefit is 50% of the primary worker’s PIA, and you only get that full amount by waiting until your own FRA to claim it.¹⁰

Early spousal claiming uses a slightly steeper reduction than retirement benefits. The first 36 months before FRA reduce the spousal benefit by 25/36 of 1% per month, and any additional months cost 5/12 of 1% per month.¹⁰ For someone with an FRA of 67, filing for spousal benefits at 62 drops the payment by 35%, leaving 32.5% of the worker’s PIA rather than 50%.³

If you turned 62 on or after January 2, 2016, deemed filing applies. When you file for either your own retirement benefit or a spousal benefit, Social Security treats it as a filing for both and pays you the higher of the two.¹¹ The older strategy of claiming spousal only while letting your own benefit grow with delayed credits is no longer available to most people.

How FRA Shapes Survivor Benefits

Survivor benefits use their own FRA, which falls between 66 and 67 depending on the survivor’s birth year. At that age, a surviving spouse receives 100% of the deceased worker’s benefit. The earliest you can claim survivor benefits is age 60, or 50 with a disability, and claiming at 60 reduces the amount to between 71% and 99% of the worker’s benefit.¹²¹³

Survivor and retirement benefits stay separate. A surviving spouse can take a reduced survivor benefit at 60 and later switch to their own retirement benefit if it grows larger, or start with their own retirement benefit and switch to a survivor benefit later. Timing matters more for survivors with their own significant work history.

Disability Benefits Convert at FRA

If you’re receiving Social Security Disability Insurance when you reach FRA, your payments convert automatically to retirement benefits. The monthly amount stays the same.¹⁴ You don’t need to file a separate retirement application, and you can’t collect both at once on the same earnings record.¹⁵

SSDI is calculated as if the recipient were already at FRA, so disability recipients don’t face the early-claiming reduction that voluntary early retirees do. The conversion at FRA is a label change, not a financial one.

FRA Is Not the Same as Medicare Age

Medicare eligibility starts at 65, but FRA for anyone born in 1960 or later is 67. Those two ages don’t move together. If you’re already collecting Social Security when you turn 65, Medicare generally enrolls you automatically in Part A and Part B.¹⁶

If you’re delaying Social Security past 65, no one enrolls you in Medicare automatically. You have to sign up during your Initial Enrollment Period around your 65th birthday.³ Missing that window can trigger a Part B late enrollment penalty that permanently raises your premiums. If you have creditable coverage through a current employer, you can delay Part B without penalty and enroll during a Special Enrollment Period after that coverage ends.¹⁷
