Social Security lets you claim your benefit anywhere from age 62 to 70, and the age you choose permanently changes your monthly amount. The rules behind that adjustment are set by law and haven't changed in decades — this calculator applies those rules directly to a benefit estimate you provide.
Full Retirement Age (FRA) Depends on Birth Year
FRA is 66 for anyone born 1943–1954, then rises gradually by birth year until it reaches 67 for anyone born in 1960 or later. This is the age at which you receive 100% of your Primary Insurance Amount (PIA) — the benefit calculated from your lifetime earnings record.
Claiming Early: The Reduction
Reduction = 5/9 of 1% per month for the first 36 months early, then 5/12 of 1% per additional month
Claiming at 62 with an FRA of 67 — the maximum possible gap — results in a permanent reduction of about 30%. The reduction is smaller the closer you claim to FRA.
Delaying Past FRA: The Increase
Increase = 2/3 of 1% per month (8% per year), stopping at age 70
Delaying from FRA to 70 increases the benefit by roughly 24% (at FRA 67) to 32% (at FRA 66), depending on birth year. Delayed retirement credits stop accruing at 70 — there's no additional benefit to waiting past that age.
Why "Breakeven Age" Matters More Than the Headline Number
A larger monthly check from delaying doesn't automatically mean more total money — it depends on how long benefits are collected. The breakeven age is the point where cumulative benefits from delaying catch up to and surpass cumulative benefits from claiming early, purely as arithmetic — it says nothing about your actual life expectancy, just when the crossover happens mathematically.
💡 This calculator estimates the claiming-age adjustment only. Your actual Primary Insurance Amount depends on your full earnings history and is available on your Social Security statement at ssa.gov — start there for the input number, then use this to compare claiming ages.
