Claim Social Security at 62 or 70? The Break-Even Math
You can claim Social Security anywhere from 62 to 70, and the monthly check changes dramatically with the date: claim at 62 and you get 70% of your full benefit — permanently. Wait until 70 and you get 124%, permanently. Same earnings record, a 77% larger check, decided entirely by when you file.
The three checkpoints
Say your full-retirement-age (67) benefit is $2,000/month:
- Claim at 62: $1,400/month — reduced ~6% per year of early claiming.
- Claim at 67 (FRA): $2,000/month.
- Claim at 70: $2,480/month — delayed credits add 8% per year past FRA. (Past 70 there's no benefit to waiting.)
The break-even
Claiming early means more years of checks; claiming late means bigger ones. The crossover lands around age 80: live to exactly 80 and the strategies roughly tie. Die sooner and 62 won; live longer and 70 wins by a widening margin. On that $2,000 benefit, living to 90 makes the lifetime totals $487,200 (claimed at 62) vs. $624,960 (claimed at 70) — a $138,000 gap.
The better frame: it's longevity insurance
Optimizing "expected lifetime dollars" misses what the benefit is for. The financial risk isn't dying early — expenses stop then too. The risk is outliving your portfolio. Delaying to 70 buys a 24%-larger, inflation-adjusted, government-guaranteed check for life, priced far cheaper than any private annuity. A 62-year-old today has roughly even odds of reaching 80 (women better than even), and it's precisely the long-lived scenarios where the bigger check saves you.
Who should claim early anyway
- Health or family history says so. A genuinely shortened horizon flips the math — that's what the break-even is for.
- You need the money. Claiming at 62 beats liquidating investments in a down market or carrying high-interest debt.
- Lower-earning spouses, sometimes. A common couples' strategy: the lower earner claims early for cash flow while the higher earner delays to 70 — because the survivor keeps the larger of the two checks. Delaying the bigger benefit protects whoever lives longest.
- Still working before FRA? The earnings test withholds benefits above ~$23k of wages — usually better to wait until you've actually stopped.
The bridge strategy
Retiring at 62 doesn't mean claiming at 62. FIRE retirees often spend from the portfolio (or run a conversion ladder in those low-income years) and let the benefit grow — the portfolio funds a "bridge" to 70, then the maxed check reduces what the portfolio must produce forever after.

Frequently asked questions
- Should I take Social Security at 62 or 70?
- Claiming at 62 pays 70% of your full benefit permanently; 70 pays 124%. The lifetime break-even is around age 80, so delay if you are healthy and can fund the gap — the larger check is cheap longevity insurance. Claim early if health or cash flow says otherwise.
- What is the Social Security break-even age?
- Roughly 80. Live to exactly 80 and claiming at 62 versus 70 yields about the same lifetime total; beyond that, delaying wins by a growing margin — about $138,000 more by 90 on a $2,000 full benefit.
- How much does Social Security grow if I delay?
- Benefits are reduced about 6% per year before full retirement age and grow 8% per year after it until 70. Claiming at 70 instead of 62 makes the monthly check 77% larger, inflation-adjusted for life.
