Social Security Retirement Benefit Calculator
Find your Full Retirement Age and see how claiming early or delaying changes your monthly Social Security benefit.
This tool applies official SSA claiming-age adjustment rules to a benefit estimate you provide. It does not calculate your benefit from your earnings history - get that figure from your Social Security Statement at ssa.gov/myaccount.

How Claiming Age Affects Your Benefit
Social Security is designed to be roughly "actuarially neutral" - claim early and you get smaller payments for more years; delay and you get larger payments for fewer years. Claiming before your Full Retirement Age permanently reduces your benefit; claiming after it earns delayed retirement credits until age 70, after which there is no further increase.

Frequently Asked Questions
Full Retirement Age is the age at which you can claim 100% of your Social Security retirement benefit, with no early-claiming reduction. It depends on your birth year: FRA is 66 for people born 1943-1954, and gradually rises in two-month steps to 67 for anyone born in 1960 or later.
Claiming at 62, the earliest possible age, permanently reduces your benefit. If your FRA is 67, claiming at 62 (60 months early) reduces your benefit to about 70% of your full amount. The reduction is 5/9 of 1% per month for the first 36 months early, and 5/12 of 1% per month for any additional months beyond that.
For each month you delay claiming past your FRA, up to age 70, you earn a delayed retirement credit of 2/3 of 1% - equivalent to 8% per year. Delaying from FRA to age 70 increases your benefit by 24-32% depending on your FRA, but there is no additional benefit to delaying past age 70.
Your personalised estimate is on your Social Security Statement, available anytime at ssa.gov/myaccount. It is based on your actual lifetime earnings record, which is why this calculator asks you to enter that figure rather than estimating it from a single salary input.
There is no single right answer - it depends on your health, life expectancy, other retirement income, and whether you plan to keep working. Claiming early gives you more years of smaller payments; delaying gives fewer years of larger payments. The lifetime total comparison in this tool can help illustrate the trade-off for a given life expectancy, but is not personalised financial advice.
