When Should You Claim Social Security?
Claiming at 62 gives you benefits earlier but permanently reduces them by up to 30%. Waiting until 70 increases your benefit by 8% per year beyond your Full Retirement Age (67 for those born after 1960). The break-even age — when the higher delayed benefit surpasses the cumulative value of early payments — is typically around age 82.
This calculator uses the SSA's Primary Insurance Amount (PIA) formula with 2026 bend points. For a precise estimate, request your Social Security Statement at ssa.gov.
🔬 Methodology & Accuracy
Formula: Average annual indexed earnings are divided by 12 to estimate AIME. The 2026 SSA PIA bend-point formula is applied, then early or delayed claiming adjustments are estimated around full retirement age 67.
