Social Security Claiming Age Calculator

Claim early or wait? The real math

Social Security is one of the few "decisions" most people make once, on autopilot — and it's worth tens of thousands of dollars over a lifetime. The core trade: claim early and get a smaller check for more years, or claim late and get a bigger check for fewer years. Which wins depends almost entirely on how long you live.

How your benefit changes by age

Assuming your Full Retirement Age (FRA) is 67:

• Claim at 62: about 70% of your FRA benefit (reduced ~30%).
• Claim at 67 (FRA): 100% of your benefit — the baseline.
• Claim at 70: about 124% (delayed retirement credits of 8%/yr after FRA).

The reductions/credits accrue monthly, so these are the landmark points; in between, the benefit changes proportionally.

The break-even age — the whole decision

Cross the break-even age and waiting wins. Using the standard factors, the catch-up points are roughly:

• 62 vs 67: breaks even around age 78.
• 62 vs 70: breaks even around age 80.
• 67 vs 70: breaks even around age 82.

If your health or family history suggests you'll live past those ages, delaying generally nets more. If not, claiming earlier often makes sense — and for many, the real answer is "not 62, but not 70 either."

What the tool deliberately ignores

• Spousal & survivor benefits — these are significant for married couples and can push the optimal age differently.
• The earnings test — if you work while collecting before FRA, benefits may be temporarily reduced.
• Taxes on benefits — a portion can be taxable depending on your other income.

For these, the best move is to check your actual benefit at ssa.gov (your personal benefit estimate) and consult a planner if you're married.

Methodology & sources

Uses the standard monthly reduction factor (5/9% for the first 36 months, 5/12% thereafter) and 8%/yr delayed retirement credit, assuming FRA 67. Defaults are illustrative; your real benefit comes from SSA. COLA is applied after the claim age.
