Use your official FRA estimate
The calculator starts with the monthly benefit shown for full retirement age rather than attempting to reconstruct indexed lifetime earnings.
US retirement-benefit claiming analysis
Compare every claiming age from 62 through 70
Start with the benefit estimate from your Social Security statement, then compare permanent age adjustments, COLA, longevity, taxes, present value, cumulative benefits, and invested after-tax payments.
Plan with context
Claiming age changes the monthly benefit permanently.
The best financial age depends on the benefit shown in your official statement, full retirement age, longevity, household needs, survivor considerations, taxes, and what earlier payments would be used for.
Early claiming reduces each month
Benefits claimed before full retirement age are permanently reduced using Social Security’s monthly adjustment formula.
Delay credits stop at 70
For people born in 1943 or later, delayed retirement credits increase the benefit by 8% per year after FRA, but no further credit accrues after age 70.
Longevity moves the crossover
Earlier claims create more checks; later claims create larger checks. Longer planning ages generally give the higher delayed benefit more time to recover missed payments.
Spouses require household analysis
A higher earner’s delayed benefit may affect a future survivor benefit. This individual model does not optimize two coordinated claiming records.
Working and taxes add rules
Earnings before FRA may withhold benefits, while other retirement income may make part of Social Security taxable. Both require tax-specific analysis.
Included
Birth-year FRA, official early and delayed factors, ages 62–70, statement benefit, COLA, tax assumption, inflation discounting, investment return, lifetime totals, chart, and comparison table.
Not included
Earnings-record calculation, earnings test, spouse, survivor, disability, family maximum, Medicare premiums, benefit taxation formula, future law changes, or withheld-benefit recalculation.
Use it well
Sign in to my Social Security for the starting estimate, compare several planning ages, consider survivor needs, and verify the chosen filing month with SSA.
