Social Security claim age: 62 vs 67 vs 70, with worked numbers
How much does waiting actually pay? Three workers, identical earnings histories, three claim ages. The gap is bigger than most people expect.

You can claim Social Security as early as 62 or as late as 70. The difference between those two choices, for an average earner, is roughly 76% more monthly income for life — and most retirees still claim early.
Here's the math, walked through with real 2026 numbers, and the situations where each choice is defensible.
The three claim ages, side by side
Take a worker with a Primary Insurance Amount (PIA) of $2,000/month at full retirement age (FRA) of 67. The Social Security Administration applies a fixed schedule of adjustments:
- Claim at 62: monthly benefit is reduced by 30% → $1,400/month.
- Claim at 67: full benefit → $2,000/month.
- Claim at 70: monthly benefit is increased by 24% → $2,480/month.
The 70-year-old gets 77% more per month than the 62-year-old — for life. Both get COLA adjustments each year. Both get spousal and survivor benefits computed off their own benefit amount. To see the exact months these ages fall on for your birth date, alongside Medicare and RMD deadlines, use the free retirement milestones tool.
"But I get more years of payments!"
This is the most common defense of claiming at 62: you get 5 to 8 extra years of checks. Doesn't that make up for the smaller monthly amount?
Let's run the numbers. Cumulative lifetime payments, ignoring COLA for simplicity:
| Claim age | Monthly | Total by age 75 | Total by age 85 | Total by age 90 |
|---|---|---|---|---|
| 62 | $1,400 | $218,400 | $386,400 | $470,400 |
| 67 | $2,000 | $192,000 | $432,000 | $552,000 |
| 70 | $2,480 | $148,800 | $446,400 | $595,200 |
The crossover ages are roughly 78 (62 vs 67) and 82 (67 vs 70). If you live to 85, claiming at 70 puts you ahead by $76,800 over claiming at 62. If you live to 90, the gap widens to $124,800. To run the same comparison with your own birth year and benefit, use the free Social Security break-even calculator.
The mortality question
The honest counter-argument: the average 62-year-old American man has a life expectancy of about 21 more years (to age 83). The average 62-year-old American woman, about 24 more years (to age 86). So roughly half of single men should be indifferent between claiming at 62 and at 70 on a pure lifetime-dollars basis.
Two things change that math:
- Couples. When the higher earner dies, the surviving spouse gets the higher of their own benefit or the deceased's benefit, for life. Delaying the higher earner's claim raises the survivor benefit too — often by decades.
- Longevity tail risk. Running out of money at 90 is a much worse outcome than "losing" a few thousand dollars to claiming late. Social Security is a lifetime annuity that the federal government can't deliver less of without an act of Congress. Buying more of it by waiting is uniquely valuable insurance.
When 62 is defensible
- You have a serious health condition that materially shortens your life expectancy.
- You need the cash to avoid liquidating retirement investments at a bad time — e.g., 2009. Tapping Social Security early to avoid selling stocks at the bottom can preserve more wealth than the higher monthly amount would have generated.
- You're the lower earner in a couple and your spouse is delaying. Couples' claiming strategies often have the lower earner claim at 62 and the higher earner delay to 70.
Notably absent from that list: fear of a benefit cut. If the projected 2032 Social Security shortfall happens, it would reduce every check proportionally no matter when you claimed — so claiming early to "beat the cut" doesn't dodge it, it just locks in a permanent reduction to hedge an uncertain one.
When 70 is defensible
- You expect to live long. Family longevity, healthy lifestyle, female single household — all push toward 70.
- You're the higher earner in a couple. Delaying raises the survivor benefit — the larger check is the one the surviving spouse keeps for life.
- You can afford to bridge the gap with savings or part-time work. Every year you delay is a 6-8% guaranteed increase in your annual benefit — better than any bond.
The Yearfold approach
The Social Security tab on Yearfold's results page values every claim age from 62 to 70: each month's benefit weighted by the chance of being alive to receive it (SSA's 2023 period life table), in today's dollars, at a 1%, 2% or 3% real discount rate. There isn't one right answer — the age with the highest expected value moves with the rate. For a 60-year-old with a $2,000 benefit at full retirement age, it's 69 at 1%, 68 at 2% and 66 at 3%. The tab shows that range, the trade-off, and what happens if you die at 75 or live to 100.
For couples, the free tab counts the spousal benefit but not survivor benefits, which usually favor the higher earner claiming later; the Couples tier's Social Security timing page counts them. The calculator itself runs your plan at the claim ages you choose — each partner on their own age — so you can see how they move your success probability.
