The age at which a retiree can collect a full, unreduced Social Security benefit has finished a slow climb that lawmakers set in motion decades ago. For everyone born in 1960 or later, that age is now 67 — not the 65 that still lives in many people’s minds, and not the 66 that applied to a slightly older group. The two-year gap between the old assumption and the current rule may sound small, but it reshapes nearly every decision about when to claim, and getting it wrong can cost a household for the rest of a retirement.
What full retirement age means
Full retirement age is the point at which a worker becomes entitled to 100 percent of the benefit their earnings record has earned. Claim before that age and the monthly payment is permanently reduced; wait beyond it and the payment grows. Because it sits at the center of the claiming decision, the exact age matters, and it is no longer a single number for everyone. It rose in stages tied to the year a person was born, the final step of a change enacted in the early 1980s to shore up the program’s finances.
For anyone born in 1960 or later, full retirement age is 67. People born in the late 1950s fall on the last rungs of the phase-in, with full retirement ages stepping up through 66 and into 67, as laid out in the Social Security Administration’s age-reduction schedule. That same schedule sets the earliest possible claiming age at 62, and it spells out how steep a price early claiming carries for those whose full retirement age is now 67.

The cost of claiming at 62
The earliest claim carries the steepest permanent discount. For a worker whose full retirement age is 67, claiming at 62 cuts the monthly benefit by about 30 percent, and that reduction lasts for life rather than lifting once full retirement age passes. In plain dollars, a benefit that would be $2,000 a month at full retirement age falls to roughly $1,400 a month for someone who claims at the first opportunity. The check arrives five years sooner, but it is permanently smaller, and the gap compounds across every year of a retirement that may run two or three decades.
That trade is not automatically a mistake. A retiree in poor health, or one who simply needs the income, may be right to claim early and take more years of smaller checks. The point is that the reduction is a deliberate, permanent price, not a temporary discount — and many people still anchored to the idea of retiring at 65 do not realize that 65 now means claiming two full years before their unreduced benefit is available.
The reward for waiting past 67
The rule works in the other direction, too. Delaying a claim past full retirement age earns delayed retirement credits, which the Social Security Administration values at about 8 percent for each year a worker waits, up to age 70. For someone with a full retirement age of 67, holding off until 70 adds roughly 24 percent to the monthly benefit for life. The credits stop accumulating at 70, so there is no reason to delay a claim beyond that age; waiting longer only forgoes payments without buying any further increase.
In dollars, the effect is easy to picture. That same $2,000 full-retirement benefit grows to roughly $2,480 a month for a worker who holds off until 70 — about $480 more every month, for life, than the full-retirement amount, and more than $1,000 above the reduced check an early claimant locks in at 62. Because delayed credits, like the early-claiming reduction, are permanent, that larger payment continues for as long as the retiree lives, and it also lifts the benefit that will rise each year with the program’s cost-of-living adjustment.
Why the higher age changes the math
Put the two ends together and the spread is dramatic. The same worker could take a permanently reduced benefit at 62 or a permanently enlarged one at 70, and the monthly check for that person can differ by well over 70 percent between the earliest and latest claiming ages. That is not a minor tuning decision; it is one of the largest financial choices most retirees will ever make, and it is made once, largely irreversibly.
The right answer depends on the individual. Life expectancy, whether a spouse will depend on the record, other sources of income, and whether a person is still working all feed into the decision. What the shift to 67 changes is the baseline everyone is working from. Advice built around a 65 retirement age, or rules of thumb inherited from a parent’s generation, now start from the wrong number, and starting from the wrong number tilts the whole calculation.
Ultimately the choice turns on how long the benefit will be collected. Claiming early means more checks, each one smaller; waiting means fewer checks, each one larger. A person who lives well into their 80s or 90s generally comes out ahead by waiting, while someone who claims early and lives a shorter retirement may collect more in total. Because no one knows their own timeline in advance, the decision is less a prediction than a choice about which risk a household would rather carry — running short late in life, or leaving some benefits unclaimed early on.
What it means for planning
The first step for anyone approaching retirement is simply to confirm their own full retirement age, because every other figure — the reduction for claiming early, the credit for waiting, the size of a spouse’s or survivor’s benefit — is measured from it. A worker who knows that number can weigh a smaller check starting sooner against a larger check starting later with clear eyes, rather than defaulting to an age that no longer means what it once did. For a decision this large and this permanent, that single piece of information is worth getting exactly right before any paperwork is filed.
