The age-62-versus-70 debate is endless among retirees. Claim Social Security at 62 and you lock in more years of checks plus a hedge against dying young. Wait until 70 and your monthly benefit grows by roughly 77%, with every future cost-of-living bump layered on top of a bigger base.
But are we looking at this wrong? Maybe the more important number is the size of the gap between what you spend and what guaranteed income covers, before you even touch your portfolio.
Call it the income gap. The average U.S. household spent about $78,535 in 2024. Retiree budgets typically run lower, so for a hypothetical case, let’s assume a household needs $60,000 a year to live comfortably. Compare two Social Security choices for the same person:
- Claim at 62: roughly $1,800 a month, or $21,600 a year. Gap to fill from savings: about $38,400.
- Claim at 70: roughly $3,200 a month, or $38,400 a year. Gap to fill from savings: about $21,600.
On a $600,000 portfolio, the first scenario forces a withdrawal rate above 6%. The second sits near 3.5%. That is the number number that matters. A 6% draw from a balanced portfolio has a meaningful chance of running dry by the mid-80s. A 3.5% draw sits close to what planners consider durable across a 30-year retirement.
Delayed Claiming as Longevity Insurance
Each year you wait past full retirement age adds roughly 8% to your benefit until 70. Think of it as the price of an inflation-protected annuity that pays for as long as you live, funded by Uncle Sam. The 2.8% cost-of-living adjustment for 2026 compounds on the larger base you locked in by waiting.
Compare that to alternatives available today. The 10-year Treasury yields about 4.6%, and its coupon payments do not rise with inflation. Few private annuities match Social Security’s combination of an 8% delayed credit and an annual COLA layered onto a larger base.
The trade-off is real. Claiming at 62 instead of 70 means eight extra years of checks. Break-even typically lands in the early 80s. Claiming early may make sense if you have a serious health issue, a family history of shorter lifespans, or a spouse who will benefit more from your early filing. If you expect to live into your late 80s or 90s, or your spouse is younger and will inherit your record as a survivor, waiting usually wins.
If you can bridge the gap by working part-time, drawing from taxable accounts first, or using Roth conversions to smooth taxes, waiting effectively converts a chunk of your portfolio into a lifetime, inflation-adjusted paycheck. But if bridging it would exhaust your savings, claiming earlier may be the only realistic path.
Run your own numbers before locking in a choice. Small changes in life expectancy or spending can shift the answer noticeably.
What to Actually Focus On
Work backward from two figures: your realistic annual spending and your realistic longevity. Then ask which claiming age produces a withdrawal rate you can still live with if you reach 90.
The mistake hardest to undo is claiming early to preserve a portfolio you did not actually need to preserve, then watching inflation eat the smaller check for 25 years. On the other hand, waiting until 70 while draining savings you will need for medical costs, hurts nearly as much. The right age is whichever one closes your income gap without forcing an unsustainable draw from what you have saved. A short session with a fee-only planner to run a Social Security timing analysis on your actual numbers is usually money well spent.
