What it computes
Claiming Social Security early gives smaller checks for more years; waiting gives bigger checks for fewer. The break-even age is when the running total from the later claim first overtakes the earlier one. The calculator applies SSA’s early-claiming reduction and delayed retirement credits[1][3] to your benefit at full retirement age, using the full retirement age for your birth year[2], and finds the crossover month by month.
Worked example
Someone born in 1962 has a full retirement age of 67. With a benefit of $2,000 a month at that age, claiming at 62 pays $1,400 a month (70% of it) and claiming at 70 pays $2,480 (124%). Ignoring investment returns, the break-even points are:
| Compare | Monthly checks | Break-even age |
|---|---|---|
| 62 vs 67 | $1,400 vs $2,000 | 78 years, 8 months |
| 67 vs 70 | $2,000 vs $2,480 | 82 years, 6 months |
| 62 vs 70 | $1,400 vs $2,480 | 80 years, 5 months |
If you expect to live past the break-even age, the later claim pays more in total. A positive return on invested early checks pushes every break-even age later.
What it ignores
- Spousal and survivor benefits. In a couple, the higher earner’s claim age sets the survivor’s check.
- Income tax on benefits, which depends on your other income.
- The earnings test for claims before full retirement age while still working.
- Cost-of-living adjustments, which apply regardless of claiming age[4], so every figure is in today’s dollars.
