Claim at 62 vs 67 vs 70: the permanent trade-off

For anyone born in 1960 or later, full retirement age is 67. Claiming at 62 cuts your benefit by 30% for life; waiting until 70 raises it by 24%. The same earnings record can therefore produce checks that differ by hundreds of dollars a month, forever.

The percentages (full retirement age 67)

With a full retirement age of 67, the adjustment works like this. Claim at 62 and you receive 70% of your PIA. At 63: 75%. At 64: 80%. At 65: about 86.7%. At 66: about 93.3%. At 67: 100%. After full retirement age, delayed retirement credits add 8% a year: 108% at 68, 116% at 69, and 124% at 70. There is no advantage to waiting past 70 — credits stop there.

The early reduction is not a flat 5% a year. It is 5/9 of 1% for each of the first 36 months before full retirement age, and 5/12 of 1% for each additional month, up to 60 months early. That is how 60 months early adds up to exactly 30%.

Take a PIA of $2,000. Claiming at 62 gives $1,400 a month. At 67 it gives $2,000. At 70 it gives $2,480. The gap between the earliest and latest claim is $1,080 a month, every month, for the rest of your life, with COLAs applied to whichever base you locked in.

Break-even illustrations (not advice)

These illustrations ignore COLAs, taxes, and investment returns; they simply compare cumulative checks. They are arithmetic, not a recommendation — your health, other income, and need for the money matter more than any break-even age.

Claim at 62 vs 67, PIA $2,000. The early claimer collects $1,400 a month for the 60 months before age 67: a head start of $84,000. From 67 on, the later claimer gets $600 a month more. Dividing $84,000 by $600 gives 140 months, or about 11 years and 8 months — a break-even age of roughly 78 and 8 months. Live longer than that and the later claim wins on total checks; live shorter and the early claim wins.

Claim at 62 vs 70, PIA $2,000. The early claimer collects $1,400 a month for 96 months: a head start of $134,400. From 70 on, the later claimer gets $1,080 a month more. Break-even is about 124 months after 70, or roughly age 80 and 4 months.

Two things these illustrations leave out cut in opposite directions. COLAs compound on a bigger base for later claimers, which pulls break-even earlier. But money collected early can be spent or saved, which pulls it later. Neither effect changes the core fact: claiming early is a bet on a shorter life, and claiming late is longevity insurance.

Why the decision is permanent

With one narrow exception, you cannot undo a claiming decision. Within 12 months of starting benefits you may withdraw your application and repay everything received, then reapply later — but you may only do this once in your lifetime. After that window, the age you claimed at is the age your benefit is based on, permanently.

This permanence is why the survivor angle matters so much for couples. A higher earner who claims early does not just cut their own check; if they die first, their surviving spouse generally steps up to the deceased's actual benefit, including any delayed credits — or the lack of them. The claiming-age guide and the survivor guide should be read together.

When claiming early can still make sense

Claiming at 62 is not always a mistake. It can be the right call if you need the income and have no better source, if your health suggests a shorter life expectancy, or if claiming lets a spouse or child collect on your record sooner. It is also sometimes forced by a job loss. The error is not claiming early; the error is claiming early without knowing it costs 30%, permanently.

Similarly, waiting until 70 is not automatically wise. It requires other income to live on for up to eight years, and it pays off only if you live well past the break-even age. For a single person with no survivor to protect and a modest life expectancy, 67 or even 62 can be the better total outcome.

A practical way to decide

Start with your PIA from your my Social Security statement, then write down the three numbers: 70%, 100%, and 124% of it. Compare each against your actual monthly expenses and other income. Then ask two questions: how long do I need this money to last, and who else depends on it after me? The answers to those two questions, not a break-even chart, should drive the decision.
