When to claim, how it's calculated, and the 8%-per-year return on delaying.

How your benefit is calculated

Your Social Security benefit is based on your highest 35 years of earnings, adjusted for wage inflation. If you worked fewer than 35 years, zeroes fill the gaps — meaning one more year of work in your 60s can replace a zero from your teens and increase your benefit. Your Primary Insurance Amount (PIA) is calculated at Full Retirement Age — 67 for most pre-retirees today.

When to claim — 62, 67, or 70?

Claiming at 62 permanently reduces your benefit by ~30%. Claiming at 70 permanently increases it by 24% above FRA. For every year you delay past FRA, you get an 8% credit — a guaranteed, inflation-adjusted return that's hard to beat with any investment. For most married couples, the higher earner should delay to 70 if possible, because that benefit also becomes the survivor benefit.

Spousal, survivor, and earnings test

A non-working or lower-earning spouse can claim up to 50% of the higher earner's FRA benefit. When one spouse dies, the survivor keeps the larger of the two benefits — which is why maximizing the high earner's benefit matters. If you claim before FRA and keep working, the earnings test temporarily reduces your benefit if wages exceed the annual limit (~$23,400 in 2026).

Key takeaways
  • Benefit is based on your highest 35 years, adjusted for wage inflation.
  • Delaying from 62 to 70 increases monthly benefits by ~76%.
  • For married couples, the higher earner typically benefits most from delaying.
  • Survivor benefits = larger of the two — another reason to maximize the higher earner.
  • The earnings test only matters if you claim early and keep working.
The part most people miss

Delaying Social Security is functionally the best annuity money can buy — inflation-adjusted, credit-risk-free, and backed by the US Treasury. No commercial annuity offers the same terms. For healthy retirees, delaying to 70 is often worth far more than any portfolio strategy.
