Best total by 88: claim at70

Understanding this calculator

Claiming age is one of the few retirement decisions with a published rulebook. Claim before your full retirement age and your check shrinks by a fixed formula; wait past it and delayed-retirement credits add 8% per year until 70. The catch: a smaller check claimed earlier is collected for more years. Which choice wins depends mostly on how long you live — which nobody knows.

That's why this calculator shows break-even ages. If you expect to live well past the break-even, waiting tends to pay more in total; if health or family history points the other way, claiming earlier can be reasonable. Married couples have extra angles — the larger earner's benefit becomes the survivor benefit, which often argues for the higher earner waiting.

Treat the output as a framing tool, not an answer. Your real benefit depends on your earnings record — pull your statement at ssa.gov before deciding anything.

Assumptions and methodology

  • Inputs use your estimated benefit at full retirement age (FRA) from your Social Security statement.
  • Early-claiming reduction: 5/9 of 1% per month for the first 36 months before FRA, then 5/12 of 1% per month beyond that.
  • Delayed credits: 2/3 of 1% per month (8%/year) between FRA and 70.
  • Results default to today's dollars; the optional COLA setting compounds benefits annually once claiming starts.
  • Earnings tests, taxation of benefits, spousal/survivor optimization, and future law changes are not modeled.

Common questions

Where do I find my FRA benefit estimate?

Create or open your my Social Security account at ssa.gov and check your statement. Use the amount shown at your full retirement age.

Is waiting until 70 always best?

No. Waiting maximizes the monthly check and total dollars if you live long enough — typically into your early 80s — but claiming earlier can make sense for shorter life expectancy, immediate cash needs, or coordinating spousal benefits.

Are these my real benefit amounts?

They're educational estimates from the standard reduction and credit formulas applied to the FRA amount you enter. Confirm actual figures with the Social Security Administration.
