Social Security Full Retirement Age by Birth Year

Full Retirement Age, or FRA, is the age at which Social Security retirement benefits are paid at their standard, unreduced level. In 2026, the answer to "what is my Full Retirement Age?" depends entirely on the year of birth. For anyone born in 1960 or later, FRA is 67. For workers born between 1955 and 1959, FRA falls between 66 and 67, increasing in two-month steps by birth year. For workers born from 1943 through 1954, FRA is 66.

Birth year is the only thing that determines FRA. The year a person retires, the year benefits are claimed, or the year a person stops working has no bearing on it. Two people both turning 66 in 2026 may have different Full Retirement Ages depending on which year they were born. This is why questions about retirement age by birth year, Social Security at age 66, and Social Security at age 67 are among the most common queries in retirement planning today.

FRA matters because it is the reference point Social Security uses to calculate every retirement benefit. Claiming before FRA produces a permanent reduction; claiming after FRA, up to age 70, produces a permanent monthly benefit increase (known as delayed retirement credits) of 8 percent per year. This guide explains the FRA chart, walks through the specific ages by birth year, and shows how FRA fits into the broader claiming-age framework that governs Social Security retirement benefits in 2026.

Key Takeaways

• Full Retirement Age (FRA) is the age at which Social Security retirement benefits are paid at their standard level, with no reduction for early claiming and no increase from delayed retirement credits.
• For workers born in 1960 or later, FRA is 67. This is the permanent FRA under current Social Security law.
• For workers born between 1955 and 1959, FRA falls between 66 and 67, increasing in two-month steps: 66 and 2 months (1955), 66 and 4 months (1956), 66 and 6 months (1957), 66 and 8 months (1958), and 66 and 10 months (1959).
• For workers born from 1943 through 1954, FRA is 66.
• Claiming at age 62, the earliest possible age, permanently reduces the monthly benefit by 30 percent below the Primary Insurance Amount for workers whose FRA is 67.
• Claiming after FRA produces monthly benefit increases of 8 percent per year, up to a maximum of 24 percent above the FRA benefit at age 70. These increases are called delayed retirement credits, and they stop accruing at age 70.
• For workers with maximum-taxable earnings across 35 years, the SSA-published 2026 maximum monthly benefits are $2,969 at age 62, $4,207 at FRA (67), and $5,181 at age 70.
• FRA determines when the Social Security earnings test no longer applies. In 2026, workers under FRA who earn above $24,480 have $1 in benefits withheld for every $2 over the limit. In the year FRA is reached, the limit rises to $65,160 with $1 withheld for every $3 over.
• Benefits withheld under the earnings test may be partially or fully recovered through an adjusted benefit rate at FRA, but recovery is not guaranteed.
• FRA is not the same as Medicare eligibility. Medicare generally begins at age 65 regardless of FRA or Social Security claiming status.
• FRA affects spousal and survivor benefit calculations because both are tied to the worker's benefit amount at FRA, not the actual amount claimed.
• Cost-of-living adjustments apply each year regardless of claiming age. The 2026 Social Security cost-of-living adjustment is 2.8 percent.
• FRA is a reference point for calculating benefits, not a requirement to stop working or start claiming benefits.

Full Retirement Age by Birth Year: Official SSA Chart

The Social Security Administration publishes the official Full Retirement Age chart at ssa.gov/benefits/retirement/planner/ageincrease.html. The chart below shows FRA by birth year under current law in 2026.

A small technical detail in SSA's rules: workers born on January 1 of any year are treated as if they were born in the previous year for FRA purposes, which can shift their FRA by two months. For the very large majority of workers, the chart above applies directly.

What Is Full Retirement Age for Social Security

Full Retirement Age (FRA) is the age at which a worker becomes eligible to receive 100 percent of their Primary Insurance Amount, the benefit calculated from their lifetime earnings record. At FRA, there is no reduction for claiming early and no increase from delayed retirement credits. The Primary Insurance Amount is the reference point Social Security uses to calculate every retirement benefit, including spousal benefits and survivor benefits paid to family members.

FRA is not a requirement to stop working or to start claiming benefits. It is a calculation reference. Workers can claim retirement benefits as early as age 62, at FRA, or as late as age 70, and benefits are adjusted based on the number of months between the claiming age and FRA. Claiming before FRA reduces the monthly benefit permanently. Claiming after FRA increases the monthly benefit permanently, up to age 70. After age 70, no further increases apply.

Claiming Age Comparison: 62 vs 67 vs 70

The table below shows how benefit amounts change at each of the three main claiming ages for workers whose FRA is 67. The percentage relationships are rule-based and apply to any worker, regardless of earnings level. The dollar figures are the SSA-published 2026 maximum monthly benefits for workers with maximum-taxable earnings across 35 working years.

The 30 percent reduction at age 62 and the 24 percent increase at age 70 are exact under current SSA rules for the FRA-67 cohort, not approximate. Although age 67 carries no reduction from the Primary Insurance Amount and is therefore the "full" benefit, claiming at 67 still produces a monthly benefit roughly 19 percent below the maximum available at age 70.

How Full Retirement Age Fits Into Social Security Benefit Calculations

Social Security benefits are calculated using a worker's 35 highest years of indexed earnings, which produce the Average Indexed Monthly Earnings, or AIME. The AIME is applied to a progressive benefit formula to produce the Primary Insurance Amount, or PIA, the benefit payable at Full Retirement Age. When benefits are claimed before FRA, a permanent reduction is applied to the PIA. When benefits are claimed after FRA, monthly benefit increases (delayed retirement credits) are added to the PIA at 8 percent per year up to age 70.

Because the PIA depends on earnings history and the claiming-age adjustment depends on FRA, two workers with identical earnings can receive very different monthly benefits depending on their birth year. A worker born in 1958 who claims at 64 is claiming 32 months before their FRA of 66 and 8 months, while a worker born in 1962 who claims at 64 is claiming 36 months before their FRA of 67. The reduction percentages differ, which is why birth year is central to understanding any claiming decision.

Why Full Retirement Age Depends on Your Birth Year

Full Retirement Age depends on birth year because the 1983 Social Security Amendments raised the retirement age gradually, rather than all at once. Before the 1983 Amendments, FRA was 65 for all workers. The Amendments phased in an increase to 67, beginning with workers born in 1938 and reaching the final FRA of 67 for workers born in 1960 or later. The phase-in is now complete, which is why FRA remains 67 for everyone born in 1960 or later under current law in 2026.

For workers born between 1955 and 1959, FRA falls in the middle of the phase-in and increases in two-month steps by birth year. The two-month step explains why FRA values for these cohorts are not whole numbers. Someone born in 1958 has an FRA of 66 and 8 months, not 66 and a half or 67. These details matter because early-claiming reductions and delayed retirement credits are measured in months, not years.

Full Retirement Age Chart Explained

The chart at the top of this article maps every relevant birth year to its FRA. Three patterns are worth noting. First, the 1943-to-1954 cohort all share an FRA of 66, regardless of where in that range they were born. Second, the 1955-to-1959 cohort is the transition zone, where each birth year adds two months. Third, every worker born in 1960 or later has an FRA of 67, with no further phase-in scheduled under current law.

The chart does not reflect when someone plans to retire. It reflects when Social Security considers a person to have reached FRA for benefit calculation purposes. Once FRA is reached, the standard benefit amount applies, the earnings test no longer applies, and the worker can earn any amount from continued work without affecting their Social Security benefit.

Full Retirement Age for Common Birth Years

Many searches focus on specific birth years because FRA changes in small increments across certain cohorts. A worker born in 1958 reaches FRA at 66 years and 8 months. A worker born in 1959 reaches FRA at 66 years and 10 months. A worker born in 1960 reaches FRA at 67. A worker born in 1962 reaches FRA at 67. The 1955-to-1959 increments come from the original 1983 phase-in design, and the 1960-or-later FRA of 67 is now the permanent rule.

This structure also explains why questions comparing Social Security at age 66 vs 67 continue to appear. The correct answer depends entirely on year of birth, not on general retirement norms or assumptions about when people typically stop working.

Is Full Retirement Age 66 or 67?

The question of whether FRA is 66 or 67 has a clear answer that depends on birth year. For workers born in 1954 or earlier, FRA is 66. For workers born between 1955 and 1959, FRA is between 66 and 67, increasing in two-month steps as shown in the chart above. For workers born in 1960 or later, FRA is 67.

This distinction matters because Social Security uses FRA as a calculation reference. Two people may both be 66 years old in 2026, but only one may have reached FRA. The other may still be months away. Understanding which cohort a worker falls into prevents incorrect assumptions about benefit amounts, work rules, and the timing of when the earnings test stops applying.

What Happens If You Retire Before Full Retirement Age

Retiring or claiming benefits before FRA produces permanent changes to Social Security benefits. Early claiming is allowed at any age from 62 onward, but it comes with reductions that last for life. These reductions are calculated based on the number of months between the claiming age and FRA.

Early claiming also interacts with work rules. In 2026, workers who claim benefits before FRA and continue working may be subject to the Social Security earnings test, which can result in benefit payments being withheld if earnings exceed certain limits.

Early Retirement at 62 and Reduced Benefits

Age 62 is the earliest age at which retirement benefits can begin. Claiming at this age produces the largest reduction. For a worker whose FRA is 67, claiming at age 62 produces a permanent 30 percent reduction below the Primary Insurance Amount. Applied to the SSA-published 2026 maximum benefit figures, this is the difference between $4,207 at FRA and $2,969 at age 62. Smaller reductions apply at each age between 62 and FRA. For FRA-67 workers, the reductions are 25 percent at age 63, 20 percent at age 64, 13.33 percent at age 65, and 6.67 percent at age 66.

The exact reduction at age 62 also depends on birth year, because workers in earlier birth-year cohorts had a closer FRA and therefore a smaller reduction at 62. The Social Security Administration publishes the following age-62 reductions by birth year:

SSA publishes the detailed reduction percentages at each early-claiming age, along with worked dollar examples for both retirement benefits and spousal benefits, at ssa.gov/benefits/retirement/planner/agereduction.html.

Working Before Full Retirement Age and Earnings Limits

In 2026, workers under FRA face an annual earnings limit of $24,480. Earnings above that level cause $1 in benefits to be withheld for every $2 over the limit. In the year a worker reaches FRA, a higher limit of $65,160 applies to earnings in the months before reaching FRA, with $1 withheld for every $3 over. Starting with the month a worker reaches FRA, the earnings test no longer applies, regardless of earnings.

Benefits withheld under the earnings test are not refunded as a lump sum. At FRA, the Social Security Administration recalculates the worker's benefit, crediting the months in which benefits were withheld and producing a higher monthly benefit going forward. Whether this recovery is full, partial, or limited depends on how long the worker lives after the recomputation and on the amount withheld. Recovery is not guaranteed.

What Happens If You Claim After Full Retirement Age

Claiming benefits after FRA produces a permanent monthly benefit increase (known as delayed retirement credits) of 8 percent per year up to age 70. For a worker with an FRA of 67 who delays all the way to age 70, this produces a total increase of 24 percent above the Primary Insurance Amount. Applied to the SSA-published 2026 maximum benefit figures, this is the difference between $4,207 at FRA and $5,181 at age 70, an additional $974 per month, or $11,688 per year, paid for life.

FRA determines when these increases begin. A worker with an FRA of 67 begins earning monthly benefit increases at age 67. A worker with an FRA of 66 and 8 months begins earning them at 66 and 8 months. Increases stop accruing at age 70, so there is no benefit to waiting beyond that age. The higher monthly benefit achieved at age 70 becomes the base amount for future cost-of-living adjustments, which means each subsequent COLA is calculated on the larger number and compounds across the remaining years of retirement.

How to Find Your Exact Full Retirement Age

Finding the exact FRA does not require guesswork. It can be determined from birth year using the chart above or through official SSA tools.

Using Birth Year to Determine FRA

The Social Security Administration publishes the official FRA chart by birth year. Workers can identify their year of birth and read FRA directly from the chart. The FRA value stays the same regardless of when benefits are eventually claimed. This information can also be confirmed through a personal My Social Security account, which displays benefit estimates calculated using the worker's specific FRA.

Using Optimization Tools Instead of Guessing

Free Social Security calculators can confirm FRA and show how it fits into benefit timing at a high level. Their limitations are that they typically rely on assumed future earnings, evaluate one claiming age at a time, and do not coordinate retirement, spousal, and survivor benefits across a household.

Sophisticated Social Security optimization software addresses these gaps. Maximize My Social Security runs hundreds of thousands of claiming combinations against a household's verified earnings data and identifies the specific filing strategy that produces the highest lifetime benefits under current Social Security rules. It covers retirement, spousal, survivor, divorcee, child, and disability benefits, applies all current rules including the Social Security Fairness Act of 2025, deeming rules, family maximum, the earnings test, and delayed retirement credits, and produces step-by-step filing instructions with the exact dates and actions for each person involved.

How Full Retirement Age Fits Into a Broader Claiming Strategy

FRA is a reference point, not a recommendation or a requirement. Claiming decisions usually involve additional factors such as spousal benefits, survivor benefits, work plans, taxes, longevity expectations, and the availability of other retirement income.

For married households, FRA affects how spousal and survivor benefits are calculated. The spousal benefit is tied to the primary worker's benefit amount at FRA, not the actual amount claimed. The survivor benefit is generally the higher of the two spouses' actual benefits at the time of death, so claiming decisions made by the higher earner directly affect the eventual survivor benefit. For workers with longer life expectancy, the timing of benefits relative to FRA shapes income later in retirement. These interactions make claiming decisions household-specific rather than rule-of-thumb decisions.
