Look up the standard full retirement age for U.S. Social Security worker retirement benefits by birth year. Full retirement age is a benefit reference point; it is different from when you can afford to stop work or qualify for another program.

Before you enter your numbers
Enter your actual birth year. If your birthday is January 1, verify SSA’s special birth-date treatment before relying on a year-only result. The tool provides a general worker-retirement schedule and does not determine your insured status.
- Birth year
Formula and calculation method
The schedule moves from age 65 for older cohorts through two-month increments, reaches 66 for births from 1943 through 1954, then rises again to 67 for births in 1960 or later. The page also identifies common earliest claiming at 62 and the end of delayed credits at 70.
Worked example
A person born in 1958 has a standard full retirement age of 66 years and eight months. A person born in 1962 has a standard full retirement age of 67. Neither result is a requirement to remain employed until that date.
How to interpret the result
The result panel reports full retirement age, earliest common retirement-benefit claiming age and latest delayed-credit age.
Early worker-retirement benefits are generally reduced relative to full-retirement-age benefits. Survivor benefits have their own age schedule, and disability eligibility follows different rules. This lookup does not calculate any payment or advise when to claim.
Why full retirement age depends on birth year
Full retirement age rises gradually from 65 for older birth cohorts to 67 for people born in 1960 or later. The calculator reproduces the month-by-month transition for birth years 1938 through 1959 instead of rounding everyone to a whole age.
Full retirement age is not the earliest claiming age. Retirement benefits can generally begin at 62, while delayed retirement credits can continue to age 70.
Use the lookup as a reference date
Full retirement age determines the reference amount for an unreduced worker retirement benefit. It does not establish whether you have enough covered work, what your earnings-based amount is, or whether an earlier application is suitable. Those questions require different records and calculations.
Write down the exact month when comparing benefit start dates. A year-only age can hide several months of reductions or credits. The result is expressed in years and months, but the input does not include a complete date of birth; verify the precise date through SSA.
Do not confuse full retirement age with the earliest claiming age
Full retirement age is the reference age used for an unreduced retirement benefit under the standard schedule; it is not the only age at which benefits can begin. Claiming earlier can reduce a worker benefit, while delaying can increase it up to the applicable limit.
Use the age lookup as a rule reference, then use the Social Security Calculator to compare estimated monthly benefits at different claiming ages. For filing, verify the date and benefit amount in your SSA record.
Use The Result In The Next Calculation
Once you identify full retirement age, use the Social Security calculator to compare an early or delayed claiming age. The age lookup does not estimate a dollar benefit, so keep the two questions separate.

Social Security Retirement Age Calculator FAQs
Is full retirement age the same as Medicare eligibility age?+
No. They concern different programs. Do not delay checking health-coverage enrollment requirements simply because Social Security full retirement age is later.
Where can I check the assumptions behind this result?+
Check the formula and limitations sections on the Social Security Retirement Age Calculator page for the assumptions specific to this tool. The methodology page explains conventions shared across calculators, and SSA: retirement age schedule is the reference for any time-sensitive statutory or product rule mentioned here.
What does the Social Security Retirement Age Calculator result include?+
The result focuses on full retirement age, earliest common retirement-benefit claiming age and latest delayed-credit age. It is calculated from the inputs shown on this page rather than from live account, market or government data. Read the formula and limitations section before transferring the result into another planning tool.
What should I change when testing another Social Security Retirement Age Calculator scenario?+
Change one major assumption at a time so you can see what drives the result. Useful inputs to test include Birth year. Use a conservative case alongside your central estimate rather than relying on only the most favorable combination.
Can the Social Security Retirement Age Calculator replace an official statement or professional advice?+
No. It is a planning calculator. Full retirement age affects benefit calculations but does not require you to stop working at that age. Use official statements and current rules when an exact legal, tax, pension or account figure is required.
