The decision of when to claim Social Security is one of the most consequential retirement choices you will make — yet most Americans claim early, leaving significant money on the table. In 2026, with the 2.8% COLA increase in effect, the monthly benefit at 70 is roughly 77% higher than at 62 for the same earnings record.
Social Security calculates your Primary Insurance Amount (PIA) based on your 35 highest-earning years, indexed for inflation. The PIA is what you receive if you claim at your Full Retirement Age (FRA).
FRA is 67 for anyone born in 1960 or later (the majority of current near-retirees). Claiming before 67 permanently reduces your benefit; claiming after 67 permanently increases it via Delayed Retirement Credits.
The break-even age is when the cumulative lifetime benefits from waiting equal the cumulative benefits from claiming earlier. Most calculations assume no investment returns on early benefits (for simplicity):
Break-even for claiming at 70 vs. 62: approximately age 80-82. Break-even for claiming at 70 vs. 67: approximately age 82-83. If you expect to live beyond the break-even age, delaying pays off. If not, claiming early makes more financial sense.
For married couples, Social Security planning is more complex. A spouse with a lower earnings record can receive up to 50% of the higher earner's PIA — but only if the primary earner has already filed.
Common optimal strategy for a high-income couple: the lower-earning spouse claims early (at 62 or FRA), generating income while the higher earner delays to 70. When the higher earner claims at 70, the survivor benefit (which the surviving spouse receives when one partner dies) is maximized — protecting the longer-lived partner.
When one spouse dies, the surviving spouse receives the higher of their own benefit or their deceased spouse's benefit. This means the higher-earning spouse's claiming decision becomes a survivor benefit decision.
A husband with a $3,400/month benefit at 70 vs. $1,938/month at 62 is also making a decision about his wife's survivor benefit if she outlives him. The difference of $1,462/month for potentially 15-20 years of widowhood can total $263,000–$350,000 in additional lifetime benefits for the survivor.
Up to 85% of Social Security benefits are taxable if your "combined income" (AGI + nontaxable interest + 50% of SS benefits) exceeds $34,000 (single) or $44,000 (MFJ). For retirees with significant investment income, this affects the real after-tax benefit of claiming at different ages.
Roth IRA conversions before claiming Social Security can reduce combined income in retirement, potentially keeping SS benefits below the taxation threshold — a powerful strategy for the right circumstances.
