How break-even is worked out
Claiming earlier gives you a head start: every month between the two ages is a check the later claimer doesn't get. After that, the later claimer gets a bigger check every month. Divide the head start by the monthly difference and you have the number of months it takes to catch up. With a return above 0%, the early checks are assumed to be invested, which pushes the crossing later.
Typical break-even ages (full retirement age 67)
| Comparison | Benefit ratio | Break-even |
|---|
| 62 vs 67 | 70% → 100% | about 78 and 8 months |
| 62 vs 70 | 70% → 124% | about 80 and 4 months |
| 67 vs 70 | 100% → 124% | about 82 and 6 months |
For context, SSA's period life table puts the average remaining life expectancy of a 65-year-old at close to 20 years, and one of a married couple at 65 has a good chance of reaching 90. See the full picture of every claiming age in the Social Security calculator.
Questions people ask
What is the Social Security break-even age?
It is the age at which the total received by claiming later catches up with the total received by claiming earlier. For 62 versus 67 it is typically about 78 or 79; for 67 versus 70 it is about 82 or 83.
Does investing early benefits change the break-even?
Yes. If you would invest the early checks and earn a real return, the break-even moves later. Enter a return above 0% to see the effect. At 0% the comparison is simple cumulative dollars.
Should I claim at the break-even age I expect to outlive?
If you expect to live beyond the break-even age, the later claim pays more in total. Many planners treat Social Security as longevity insurance: the risk that matters is running short at 90, not collecting less if you die at 75.
Are the figures before tax?
Yes. Up to 85% of benefits can be taxable depending on your other income, and the same share applies whichever age you claim, so the break-even age barely changes.
