• The common break-even framing treats Social Security as an investment to be maximized against life expectancy, but its economic function is insurance against outliving savings.
• Delaying buys a larger stream of inflation-indexed lifetime income, similar to an inflation-indexed annuity.
• For couples, delaying the higher earner's benefit primarily buys survivor protection, which the individual break-even calculation ignores.
The Social Security claiming decision is commonly framed as a single question: at what age does the larger delayed benefit recover the checks forgone by waiting? A worker who claims at 62 receives 70% of the benefit payable at a full retirement age of 67; delaying to 70 raises it to 124% through delayed-retirement credits of 8% per year.1 Cumulative benefits from the two paths cross near age 80 undiscounted, and closer to 84 when discounted at current real yields. That crossover is the "break-even age."2 The rule is a wager on longevity: delay only if a retiree expects to live past it.
The framing is intuitive and easily quantified, and it influences behavior: experimental evidence shows that presenting the decision as a break-even calculation encourages earlier claiming.3 Not every early claim reflects the frame; some reflect job loss, poor health, or an immediate need for income. But where the frame is doing the work, it is the wrong ruler.
Social Security's economic function is longevity insurance: protection against outliving a household's assets. The break-even test weighs every outcome equally, but the outcome that matters most is a long life the retiree cannot self-fund. Delaying converts portfolio dollars into a larger stream of inflation-indexed income that lasts for life, which is similar to buying an inflation-indexed annuity.4
The Couples Blind Spot
The break-even calculation treats the claimant in isolation. For couples, the higher earner's benefit continues as the survivor benefit for the longer-lived spouse. A surviving spouse claiming at or after full retirement age receives the greater of the benefit the deceased was receiving or 82.5% of the deceased's PIA.5 At the first death, the household also loses the smaller of its two checks, so income contracts when the survivor is most exposed. Claiming early therefore also permanently lowers the floor the survivor lives on.
This doesn’t mean early claiming is a mistake in every scenario, only that break-even reasoning answers the wrong question. What matters is not whether a retiree beats an actuarial crossover, but how to insure against a long life that outlasts its assets. Measured that way, the answer shifts toward delay for many households, and more so for couples.

2 Source: SS&C ALPS Advisors Research, based on SSA benefit rules for a worker with a full retirement age of 67, comparing claiming at 62 with claiming at 70. Cumulative benefits cross at about age 80.3 undiscounted and about 83.6 when discounted at a 2.6% real rate, approximating the 10-year Treasury Inflation-Indexed Security yield of 2.63% as of 09/22/2026 (Federal Reserve Bank of St. Louis. (n.d.). Market yield on U.S. Treasury securities at 10-year constant maturity, quoted on an investment basis, inflation-indexed [DFII10] [Data set]. FRED). Excludes mortality, taxes, and spousal benefits. Research finding delay actuarially advantageous for a large subset of retirees shows the largest gains at low real rates (Shoven & Slavov, note 7). Higher real yields raise the cost of the checks forgone, but do not change the need to insure against a long life.
