Social Security retirement benefits: Definition, Formula and Example
U.S. Social Security retirement benefits are monthly benefits based on a worker’s covered earnings record, eligibility and claiming age.
Scope: U.S. Social Security worker retirement benefits; the numerical factor applies to people born in 1960 or later.
Other names and related labels: U.S. Social Security; Full retirement age.
How it works
Full retirement age varies by birth year. Claiming a worker benefit early reduces the amount relative to full retirement age, while delayed retirement credits can increase it up to age 70. Spousal and survivor benefits follow different rules, and work before full retirement age can affect payments.
Illustrative worker benefit = full-retirement-age benefit × applicable claiming-age factor
The earnings-based benefit must first be established. A claiming factor alone does not calculate eligibility or the complete earnings record.
A hypothetical $2,000 full-retirement-age benefit
For a worker born in 1960 or later, full retirement age is 67.
- SSA’s age-62 worker factor is 70% for this birth cohort.
- Early monthly benefit: $2,000 × 70% = $1,400.
The illustrated age-62 worker benefit is $1,400 a month, before other adjustments.

A later benefit is not automatically the best personal choice
Lifetime comparisons depend on longevity, household benefits, work, tax and the value of earlier payments. The calculator is an estimate and does not replace the SSA earnings record or benefit determination.
