Social Security at 62 vs 67 vs 70: The Real Math

·9 min read

When to claim Social Security is the single biggest financial decision most people make in retirement, and it's largely irreversible. Claim at 62 and your monthly check is permanently smaller. Wait until 70 and it's dramatically larger. The difference over a lifetime can run into the hundreds of thousands of dollars. Here's the actual math, without the sales pitch.

Your Full Retirement Age Is the Anchor

Everything is measured against your Full Retirement Age (FRA). For anyone born in 1960 or later, FRA is 67. At FRA you receive 100% of your calculated benefit. Claim earlier and it's reduced; claim later and it grows. You can start as early as 62 or wait as late as 70 — there's no benefit to waiting past 70.

Claiming at 62: The Cost of Going Early

Claiming at 62 — the earliest age — permanently reduces your benefit to roughly 70% of your full amount if your FRA is 67. That reduction doesn't go away when you hit 67; it lasts for life. About a third of people still claim at 62, often out of necessity. It can be the right call if you have serious health concerns, no other income, or you're out of work and have no better option. But it's the most expensive choice over a long retirement.

Waiting to 70: The 8% Raise

For every year you delay claiming past your FRA, your benefit grows by about 8% per year until 70 — these are called delayed retirement credits. Wait from 67 to 70 and your monthly benefit is roughly 24% higher than your full amount, and about 76% higher than if you'd claimed at 62. That larger check is also the base for future cost-of-living adjustments, so the gap compounds over time.

The Break-Even Question

The trade-off is simple to state: claim early and you get smaller checks for more years; wait and you get larger checks for fewer years. The 'break-even age' — where waiting overtakes claiming early in total dollars received — typically lands somewhere in the late 70s to early 80s. If you expect to live past that, waiting usually wins on total lifetime benefits. If you don't, claiming earlier may come out ahead. Your health and family longevity matter enormously here.

It Is Not Purely About the Math

Longevity insurance is the other side of this. A larger Social Security check is guaranteed, inflation-adjusted income you cannot outlive — which is exactly what protects you if you live into your 90s and other savings run thin. For married couples there's an added wrinkle: the higher earner's decision also sets the survivor benefit their spouse may live on for years. Delaying the higher earner's benefit often protects the surviving spouse.

Bottom Line

There's no universally 'right' age — but there is a right answer for your situation. If you're healthy, expect a long life, and can afford to wait, delaying toward 70 buys you the largest guaranteed lifetime income. If your health is poor or you have no other way to pay the bills, claiming earlier can be reasonable. Run your own numbers at ssa.gov, and if you're married, decide as a couple.
