Social Security Timing: Should You Claim at 62, 67, or 70?

The claiming-age decision can swing lifetime benefits by six figures. Here is the math behind early vs. delayed claiming — and the factors the break-even calculators leave out.

The basic math

Your full retirement age (FRA) is 67 for anyone born in 1960 or later. Claiming earlier or later permanently changes your monthly check:

Claim at 62: benefit reduced about 30% below your FRA amount
Claim at 67 (FRA): 100% of your earned benefit
Claim at 70: benefit increased 24% above FRA (8% per year of delay)

The spread from 62 to 70 is roughly 77% — a $2,000 FRA benefit becomes about $1,400 at 62 or $2,480 at 70, inflation-adjusted for life.

The break-even view (and its limits)

Simple break-even math says delaying from 62 to 70 pays off if you live past roughly age 80–82. With average life expectancy for a 65-year-old already in the mid-80s — and joint life expectancy for a couple even longer — delay wins on paper more often than not.

But break-even analysis ignores several things that matter.

Factors beyond break-even

Survivor benefits. When one spouse dies, the survivor keeps the larger of the two benefits. Delaying the higher earner's claim is effectively longevity insurance for the surviving spouse — often the strongest argument for waiting until 70.
The earnings test. If you claim before FRA and keep working, benefits are temporarily withheld above an annual earnings limit. Withheld amounts are restored later, but it complicates early claiming while employed.
Taxes. Up to 85% of benefits become taxable as other income rises. Delaying benefits while spending from IRAs (or doing Roth conversions) in your 60s can shrink both future RMDs and the tax on your eventual benefits.
Portfolio pressure. Delaying means your savings carry the load from 62–70. Whether that improves or worsens plan survival depends on your balances and market returns — this is testable with a Monte Carlo simulation.
Health and family longevity. A serious health condition legitimately tilts the math toward claiming earlier.

Common couple strategies

Higher earner delays to 70; lower earner claims earlier. Maximizes the survivor benefit while providing income sooner.
Both delay when other assets can bridge the gap and longevity runs in the family.
Spousal benefits (up to 50% of the worker's FRA amount) require the worker to have filed — timing interacts, so model it rather than guessing.

The bottom line

There is no universal right age — there is a right age for your plan. The decision interacts with withdrawals, Roth conversions, taxes, and survivor protection, which is why it belongs inside a full year-by-year projection rather than a standalone calculator.
