Learn How Full Retirement Age Affects Social Security

What Full Retirement Age Means and Why It Matters

Full Retirement Age (FRA) is the age at which the Social Security Administration considers you to have reached the point where you can receive your complete benefit amount. This age is not the same for everyone. The year you were born determines when your FRA occurs. Understanding this concept is important because it directly affects how much money you will receive each month from Social Security.

The Social Security Administration uses FRA to calculate your Primary Insurance Amount (PIA), which is the monthly payment you receive. If you claim benefits before reaching FRA, your monthly payment will be reduced. If you delay claiming until after FRA, your monthly payment will increase. This means the timing of when you claim benefits can significantly impact your lifetime earnings from Social Security.

Congress established different FRAs for different birth years. For people born in 1943 through 1954, FRA is age 66. For those born between 1955 and 1959, FRA increases gradually from age 66 and 2 months to age 66 and 10 months. For people born in 1960 and later, FRA is age 67. These changes were made through legislation passed in 1983 to help adjust for increasing life expectancy.

FRA differs from the earliest age you can claim Social Security benefits. You may claim benefits as early as age 62, but doing so before reaching FRA means accepting a permanently reduced payment. The reduction can be as much as 30 percent for someone born in 1943 or later who claims at age 62 instead of waiting for FRA.

Practical takeaway: Find your birth year in your Social Security statement or the SSA.gov website to determine your specific FRA. Write down this number, as you will reference it when making decisions about when to begin receiving benefits.

How Birth Year Determines Your Full Retirement Age

Your Full Retirement Age is determined entirely by the year you were born. The Social Security Administration created a schedule that gradually increases FRA over time. This schedule was implemented to reflect increases in average life expectancy and to help ensure the long-term financial stability of the Social Security system.

For those born between 1943 and 1954, Full Retirement Age is 66. This was the standard retirement age for many decades. If you were born in any year during this range, you will reach FRA at age 66, regardless of whether you were born in January or December of 1943, or any other year in that span.

For those born in 1955, FRA is 66 and 2 months. The increase continues with each subsequent birth year:

• Born in 1956: FRA is 66 and 4 months
• Born in 1957: FRA is 66 and 6 months
• Born in 1958: FRA is 66 and 8 months
• Born in 1959: FRA is 66 and 10 months
• Born in 1960 or later: FRA is 67

If you were born on January 1st of any year, you are technically considered to have been born in the previous year for Social Security purposes. This is an important exception to remember when determining your FRA. For example, if you were born on January 1, 1943, the SSA considers your birth year to be 1942, which means your FRA would actually be 65 and 8 months, not 66.

The gradual increase in FRA was intentional policy. Rather than changing FRA suddenly for all future retirees, lawmakers chose to phase in the increase over a 22-year period. This allowed workers time to plan and adjust their retirement strategies. Workers born in different years have had different amounts of time to prepare for their individual FRA.

Practical takeaway: Locate your official birth year in your Social Security statement or visit ssa.gov to confirm your exact FRA. If you were born on January 1st, verify whether the SSA lists your birth year as the year you were born or the previous year, as this affects your FRA calculation.

The Impact of Claiming Before Full Retirement Age

If you claim Social Security benefits before reaching your Full Retirement Age, your monthly payment will be permanently reduced. The reduction is not temporary—it applies to every payment you receive for the rest of your life. The earlier you claim relative to your FRA, the larger the reduction will be.

For someone with a FRA of 67 who claims at age 62, the reduction is approximately 30 percent. This means if your full benefit at FRA would be $1,000 per month, claiming five years early would reduce it to about $700 per month. If you live for many years in retirement, this reduced payment adds up to a significant lifetime difference.

The Social Security Administration uses a specific formula to calculate reductions for early claiming. The reduction is not the same percentage for every year you claim early. The first three years of early claiming result in a reduction of 6.67 percent per year (or 0.556 percent per month). Any years beyond three years of early claiming result in a reduction of 5 percent per year (or about 0.417 percent per month). This means the reduction per year decreases slightly the earlier you claim.

Even if you claim early, you still cannot receive benefits before age 62. This is the earliest age the Social Security Administration allows. Some people may have circumstances that make early claiming appealing—such as health concerns, job loss, or immediate financial need. However, the permanent reduction in monthly benefits is an important trade-off to understand.

People who claim before FRA and continue working may also face earnings limits. For 2024, if you are under FRA and earning over $23,400 per year, the SSA will reduce your benefits by $1 for every $2 you earn above that limit. This earnings test stops once you reach FRA in the calendar year you turn FRA. These reductions end permanently once you reach your FRA, even if you are still working.

Practical takeaway: If you are considering claiming before FRA, calculate your projected lifetime benefits by comparing early claiming scenarios with waiting until FRA. The Social Security Administration provides a benefit calculator on its website that you can use to explore different claiming ages and see the monthly and lifetime payment differences.

The Advantage of Delaying Benefits Past Full Retirement Age

When you delay claiming Social Security benefits past your Full Retirement Age, your monthly benefit amount increases. This increase is called the Delayed Retirement Credit (DRC). For every month you delay claiming after reaching FRA, your benefit grows by approximately 0.667 percent (or 8 percent per year). This increase continues until you reach age 70, after which further delays no longer increase your benefit.

The financial advantage of delaying can be substantial. If your FRA is 67 and your full benefit is $1,000 per month, waiting until age 70 to claim would increase your monthly payment to approximately $1,240. Over the course of a long retirement, this difference compounds significantly. Someone who receives higher monthly payments starting at age 70 may receive more total lifetime benefits than someone who claimed at 67, even though they started receiving payments later.

The decision to delay depends partly on life expectancy. Actuarial research shows that people who live longer than average (into their mid-80s or beyond) generally receive more total lifetime benefits if they delay claiming. However, people who pass away before age 82 or 83 may receive more total benefits if they claim earlier. No one can predict exactly how long they will live, which makes this decision uncertain for everyone.

Delaying also benefits your household and family members who may receive benefits based on your record. If you are married, your spouse may receive a higher spousal benefit based on your increased Primary Insurance Amount. If you have minor children or disabled adult children, they may also receive higher child benefits. Similarly, if you pass away, your surviving spouse and children would receive higher survivor benefits if you delayed claiming and increased your benefit amount.

There are no earnings limits once you reach your FRA. This means you can continue working and earning any amount of income without any reduction to your Social Security benefits. This makes FRA a significant milestone—once you reach it, you can claim benefits and continue working without any financial penalty from the Social Security Administration.
