Social Security Breakeven Calculator
Crossover age for 62 vs 70 claiming.
What it does
Claiming early pays now but less monthly for life, while waiting skips eight years of checks for larger ones after. Breakeven is the age where waiting pulls even: total lifetime benefits match on both paths. Living past it favors patience.
The tool above divides skipped checks by the monthly gap. With $1,500 at 62 and $2,640 at 70, $144,000.00 skipped meets $1,140.00 more monthly at 126.3 months past 70, or age 80.5 years. A $2,000 versus $3,520 pair gives the same 80.5 because the ratio matches.
Money timing, health, work, and taxes all bend the simple age. Discounting future dollars pushes breakeven later, working past 62 trims early checks through the earnings test, and spousal plus survivor benefits rewrite household math entirely.
This page compares two fixed amounts undiscounted. It does not model COLAs, taxes, earnings tests, or survivor options. Use it as a starting frame before the full filing rules.
How to use
- Enter the age 62 monthly benefit.
- Enter the age 70 monthly benefit above it.
- Read breakeven age first.
- Read the skipped total.
- Read the monthly gap.
- Weigh health and taxes beside the age.
Formula
- b62
- Monthly benefit if claimed at 62, in dollars.
- b70
- Monthly benefit if claimed at 70, above b62.
- skipped
- 96 skipped checks from 62 to 70.
Undiscounted breakeven between two fixed monthly amounts with eight bridging years. At age 70 benefit at or below age 62 there is no crossover. Inflation adjustments and taxes sit outside this line.
Worked example
Example: $1,500 at 62 vs $2,640 at 70
Defaults: $1,500 at 62 with $2,640 at 70, no taxes or spousal rules. Eight bridging years.
- Inputs: $1,500 at 62 with $2,640 at 70.
- Skipped: 1500 times 96 is $144,000.00 skipped.
- Gap: 2640 minus 1500 is $1,140.00 more monthly.
- Months: 144000 / 1140 is 126.3.
- Age: 70 plus 126.3 / 12 is 80.5 years. Tool shows the same.

Questions
How is breakeven figured?
Skipped 62 to 70 benefits / monthly gap past 70. Here 126.3 months to age 80.5 years.
What does the age mean?
Living past it favors waiting; earlier favors claiming. Here 80.5 years.
Why 96 months skipped?
Eight years times 12. Skipped months always 96 here.
Is this the full claiming choice?
No. Taxes, earnings test, spousal and survivor rules all shift the true call.
Does health change the answer?
Yes. Health, work plans, and discounting move it more than rounding.
Does full retirement age matter?
No. Full retirement age varies by birth year; 62 to 70 spans the window either way.
