Her grandmother just turned 103. Her mother is 84 and still drives. Her aunts made it into their late 90s. She is 65, healthy, recently retired, and staring at a Social Security statement that offers her a check today or a larger one later. Her instinct is to take it while she can.
That expectation usually arrives framed as a question: when do I break even? The most-quoted answer lands somewhere around age 82 or 83 for someone choosing between full retirement age (FRA) and 70. For a woman whose family routinely lives past 95, that framing hides the actual risk she faces.
Why break-even is the wrong question for her
For someone born in 1960 or later, FRA is 67. Claiming at age 62 permanently cuts the benefit by roughly 30%. Waiting past 67 earns delayed retirement credits of about 8% per year, so a benefit claimed at 70 lands near 124% of the full retirement age amount. Cost-of-living adjustments (COLAs) then compound on that larger base. The 2026 COLA is 2.8%.
If her FRA benefit would be $2,500 a month, claiming at 62 drops it to roughly $1,750. Waiting until age 70 pushes it to about $3,100. That gap of more than $1,300 a month lasts the rest of her life, and every future COLA scales off the larger number.
The standard break-even argument says take the smaller check sooner, invest the difference, and you come out ahead if you die before 82 or 83. But if she lives to 98 like her aunts, every month past the break-even age is pure gain, and the gain is inflation-adjusted income she cannot outlive.
Social Security works best as insurance against living a very long time. The danger worth insuring against is outliving her money at 92.
What conditional longevity actually means
People who reach 65 in good health have a meaningful chance of reaching their late 80s or 90s, and a small but real share reach 100. Social Security’s actuarial tables show remaining life expectancy at 65 sitting near 20.5 years on average, and that average buries enormous variation. A healthy 65-year-old with multiple relatives in their 90s sits well above the average. She is in the long tail, and that tail is where guaranteed lifetime income earns its keep.
No private investment product replicates this combination: a check that arrives every month until death, adjusted each year for inflation, backed by the federal government. A bond portfolio yielding roughly 4.5% on 10-year Treasuries can be drained. Social Security cannot, the latest shortfall notwithstanding.
How the rest of her picture has to cooperate
Delaying only works if she can bridge the gap. That usually means drawing from savings, working part-time, or both, between the ages of 65 and 70. For a married higher earner, the survivor benefit a spouse inherits is based on what the deceased was receiving, so delaying lifts the floor for a potentially long-lived widow or widower.
Tax planning matters too. The years between retirement and 70 are often the lowest-income years of a retiree’s life, which makes them useful for Roth conversions or realizing capital gains at lower rates before required minimum distributions (RMDs) and a larger Social Security check arrive together.
What she should actually weigh
Two dynamics deserve the most careful look before she decides:
- Family longevity and personal health. Multiple relatives in their 90s, no major chronic conditions, and a clean medical history all point toward the longevity-insurance case. A recent serious diagnosis, single status with no survivor to protect, or short family lifespans point the other way, and claiming earlier becomes reasonable.
- Whether she can afford to wait. If drawing down savings for five years would leave her anxious or undercapitalized, the math on paper does not matter. The decision has to be livable day to day.
The mistake hardest to undo is locking in a permanently smaller check at 62 and then living to 95. Waiting and dying at 72 costs her nothing she will feel. Pulling a benefit estimate from the Social Security Administration and modeling both scenarios side by side is an afternoon’s work and the only way to see her own numbers clearly. Every family is different, and a small detail in her health or finances can tip the answer.
