When to claim Social Security

You can start Social Security retirement benefits in any month from age 62 to 70, and the month you pick sets your check for life. Claim at 62 with a full retirement age of 67 and you receive 70 percent of the benefit your earnings record has produced ¹. Wait until 70 and you receive 124 percent, with every future cost-of-living adjustment compounding on the larger base ².

That spread, a gap of roughly 77 percent between the smallest and largest version of the same benefit, is why claiming age gets so much attention. There is no answer that fits everyone. Health, savings, work plans, and a spouse's benefit all pull on the decision, and the question is less "which age wins on average" than "which risks do you most need to cover." This article lays out the arithmetic first, then the ways of thinking about it, then the coordination questions for couples and workers, and finally the errors that show up over and over.

What each claiming age pays#

Benefits shrink by five-ninths of 1 percent for each of the first 36 months you claim before full retirement age, and five-twelfths of 1 percent for each month beyond 36 ¹. Waiting past full retirement age earns delayed retirement credits of two-thirds of 1 percent per month, 8 percent per year, until they stop at 70 ². For anyone born in 1960 or later, full retirement age is 67; the schedule for earlier birth years appears in retirement age.

Two clarifications save a lot of confusion. First, these adjustments are actuarial, not a reward or penalty: the system aims to pay similar lifetime totals to a person with average longevity no matter when they claim. Second, claiming and retiring are separate decisions. You can stop working at 62 and claim at 67, living on savings in between, or keep working at 64 while collecting, subject to the earnings test below.

Break-even math and its limits#

The classic way to compare ages is to find the break-even point. Take the $2,000 example. Claiming at 62 pays $1,400 a month, so by age 67 you have collected $84,000 that the patient claimant has not. Waiting to 67 pays $600 more each month, and $84,000 divided by $600 is 140 months: the two paths hold even money just before age 79. Run the same numbers for 67 versus 70 and the break-even lands around age 82 and a half. Live longer than the break-even age and the later claim wins; die sooner and the earlier claim did.

Break-even analysis is a fine sanity check and a poor master. It usually ignores that COLAs compound on the bigger benefit, that benefits can be taxed differently at different income levels, and that money claimed early could be invested, points that can shift the crossover a year or two in either direction. The deeper problem is that it treats your lifespan as a number you can plan around. You get one draw from that distribution, not the average. A decision that "wins" if you die at 75 offers no comfort in the years after 90, which is exactly when savings tend to be thinnest.

The longevity insurance view#

Many retirement researchers frame the choice differently: Social Security is the cheapest longevity insurance most people can buy. The Social Security Administration's own publication puts a 65-year-old man's average life expectancy at about 84 and a 65-year-old woman's at about 87, and about one in three 65-year-olds will live to at least 90 ³. For a married couple, the odds that at least one spouse reaches 90 approach a coin flip.

Each year you delay costs twelve months of checks and buys an income stream 5 to 8 percent larger that lasts as long as you do and rises with inflation. Buying an equivalent inflation-adjusted lifetime annuity from an insurer generally costs more, when it is available at all. People with enough savings sometimes build a "bridge": spending deliberately from a 401(k) or IRA between retiring and claiming, in effect converting a slice of the portfolio into a larger guaranteed benefit. How that fits into a drawdown plan is part of retirement withdrawal strategies.

The insurance logic reverses for some people. A serious illness or a family history of short lifespans weakens the case for waiting, since the extra dollars arrive in years you are less likely to see. So does simple necessity: if there are no savings to bridge the gap and work is not an option, claiming early is not a mistake, it is the plan working as designed. And retirees who feel real distress watching a portfolio fund every grocery run sometimes value the early check for reasons a spreadsheet does not capture.

Claiming as a couple#

For married couples, the most important number is usually the higher earner's benefit, because it outlives the marriage. When one spouse dies, the survivor keeps the larger of the two checks and loses the smaller; the survivor benefit can equal 100 percent of what the deceased spouse was receiving, including delayed credits ⁴. A higher earner who waits until 70 is therefore buying insurance on two lives, and the payoff lasts until the second death. The lower earner's claiming age, by contrast, mostly affects the years both are alive, which is why analysts often describe the common pattern of the lower earner claiming earlier and the higher earner waiting.

Spousal benefits follow different rules than retirement benefits. A spouse can receive up to 50 percent of the worker's full-retirement-age amount, reduced if claimed before the spouse's own full retirement age, and spousal benefits earn no delayed credits, so there is nothing gained by waiting past full retirement age for a spousal-only amount ⁵. Under the deemed filing rules that have applied to everyone born after January 1, 1954, filing for either retirement or spousal benefits is treated as filing for both, which closed the old tactic of collecting a spousal benefit while your own grew ⁵.

Survivors kept their flexibility. Widows and widowers can claim a survivor benefit as early as 60, at 71.5 percent of the deceased worker's amount, and switch to their own retirement benefit later, or claim their own reduced benefit first and switch to the unreduced survivor amount at full retirement age ⁴. Divorced spouses who were married at least ten years and have not remarried can claim on an ex's record under the spousal rules, without affecting the ex's benefits.

If you keep working#

Claiming before full retirement age while still working brings the retirement earnings test into play. In 2026, $1 in benefits is withheld for every $2 you earn above $24,480; in the calendar year you reach full retirement age a gentler version applies, $1 for every $3 above $65,160, counting only earnings in the months before the month you reach that age ⁶. Only wages and self-employment earnings count; pensions, IRA withdrawals, and investment income do not ⁷.

The earnings test looks like a tax and mostly is not. At full retirement age, your benefit is recalculated to give credit for the months that were withheld, so much of the money comes back as a permanently higher check ⁷. Still, the combination of a reduced early benefit and withheld checks means people who plan to keep earning above the limits often gain little from claiming early. The mechanics, including the special monthly rule for the first year, are covered in working while receiving Social Security. Note that Medicare runs on its own schedule: eligibility begins at 65 whether or not you have claimed, and delaying Social Security is not a reason to delay Medicare enrollment.

Earnings can also raise a benefit directly. Benefits are refigured annually, so a strong earnings year late in a career can displace a low year in your top 35 and nudge the check upward, whatever your claiming age.

Mistakes that come up again and again#

Claiming at 62 by default. Sixty-two is the earliest age, not a deadline, and the reduction is permanent. The choice deserves the same attention as any other decision involving hundreds of thousands of lifetime dollars, and it is one piece of a larger retirement plan, not a reflex.

Ignoring the survivor consequence. A higher earner who claims at 62 is not just shrinking their own check; they are setting the ceiling on what a surviving spouse may live on for decades ⁴.

Claiming early because of trust fund headlines. The trustees project the retirement fund's reserves run short in the early 2030s, which would trim scheduled benefits if Congress did nothing. Locking in a 30 percent reduction today to hedge a smaller, hypothetical future cut is a trade worth calculating rather than assuming; the solvency picture is laid out in the main Social Security article.

Quitting work, or refusing to claim, because of the earnings test. Withheld benefits are largely restored at full retirement age, so the test should shape the timing calculation, not end it ⁷.

Planning around strategies that no longer exist. A 2015 law ended "file and suspend," and the spousal-then-switch restricted application closed to everyone born after January 1, 1954 ⁵. Claims that a clever filing trick can still unlock both benefits at once are a red flag, sometimes for outdated advice and sometimes for a sales pitch.

Not checking the earnings record. Your benefit is computed from your recorded earnings, and a missing year quietly shrinks it. A my Social Security account at ssa.gov shows the record and lets you flag errors, and how benefits interact with your tax return is covered in taxes in retirement.

Waiting past 70. Delayed credits stop at 70, so later claiming only forfeits checks ².

Note: There is a limited do-over. Within 12 months of approval you can withdraw your application, repay everything received (including any Medicare premiums withheld), and reset as if you never claimed; the Social Security Administration allows this once per lifetime. After full retirement age, you can instead suspend payments and earn delayed credits until 70 without repaying anything ⁸.
