Claiming between 62 and 70 changes your monthly check by roughly 77% — permanently. Model every claim age against your birth year, life expectancy and cost-of-living assumptions to find the breakeven point and the highest present-value choice.
Your assumptions
Monthly benefit by claim age
Percentage of your $3,000 full retirement age benefit, applying SSA early-claim reductions and 8% per year of delayed retirement credits.
Cumulative benefits: claiming at 62 vs. 70
Total nominal dollars collected by each age, including cost-of-living increases. Where the lines cross is your breakeven.

How Social Security claim age changes your benefit
Your primary insurance amount is what you receive at full retirement age — 67 for someone born in 1965. Claiming earlier cuts the benefit by 5/9 of 1% per month for the first 36 early months and 5/12 of 1% per month beyond that, so claiming at 62 with an FRA of 67 costs 30% permanently. Waiting past FRA adds delayed retirement credits of 8% per year until age 70, and cost-of-living adjustments compound on top of whichever base you lock in.
Reading the breakeven age
The early claimer banks checks for years before the later claimer starts. The later claimer's larger monthly amount slowly erases that head start; the age where cumulative totals cross is the breakeven — typically the late seventies to early eighties. Live past it and delaying wins; die before it and claiming early wins. Because that risk is asymmetric — running out of money late in life hurts far more than leaving a smaller estate — delaying often functions as inflation-adjusted longevity insurance.
The tax angle most calculators miss
Claim timing is really a tax decision. Every year you delay is a year of low taxable income you can fill with Roth conversions at 12% or 22% instead of facing RMDs at 24%+ later. Model the whole picture in the full retirement plan, or start with the Roth IRA growth calculator.
