How it works

Benefit is calculated from your top-35 earning years, indexed for inflation, to produce AIME (Average Indexed Monthly Earnings). PIA (Primary Insurance Amount) applies a progressive bend-point formula. Claiming at 62 reduces benefits by up to 30%; delaying to 70 increases by 8%/year after full retirement age. Break-even for delayed claiming is typically around age 80. Spousal and survivor benefits have separate rules.
