Filing for Social Security at 62, the earliest age most workers can, permanently trims the monthly benefit by about 30 percent for anyone whose full retirement age is 67. That reduction is not a temporary penalty that reverses once full retirement age arrives; it holds for the rest of the retiree’s life and follows into a surviving spouse’s check. Waiting works in the opposite direction, adding roughly 8 percent a year up to age 70. Deciding when to file is among the largest financial choices a retiree makes, and it cannot be undone after the first few months.
Why Age 62 Costs Nearly a Third of the Full Benefit
Social Security sets a full retirement age at which a worker collects 100 percent of the benefit earned, and for everyone born in 1960 or later that age is 67. Claiming before then reduces the check by a fixed amount for each month of early filing. The formula subtracts five-ninths of one percent for each of the first 36 months claimed early and five-twelfths of one percent for every month beyond that.
Running that math over the full 60 months between 62 and a full retirement age of 67 produces a reduction of about 30 percent. A worker entitled to $2,000 at 67 would collect roughly $1,400 by filing at 62, a difference of about $600 every month for as long as benefits are paid. Because the reduction is baked into the benefit permanently, the smaller figure becomes the base that all future cost-of-living adjustments build on, widening the gap in dollar terms over time.
The exact reduction depends on the birth year that sets a worker’s full retirement age. People born before 1960 have a slightly earlier full retirement age and a somewhat smaller reduction at 62, while the 30 percent figure applies to the large group now reaching retirement with a full retirement age of exactly 67. Anyone unsure of the figure can find their personal reduction on a Social Security benefit estimate.

The Reward for Waiting Past Full Retirement Age
The reduction for filing early has a mirror image on the other side of full retirement age. Every year a worker delays past 67, up to age 70, Social Security adds delayed retirement credits worth 8 percent a year. Holding out to 70 lifts the benefit to 124 percent of the full retirement amount, and there is no reason to wait beyond 70 because the credits stop accruing at that point.
Stacking the two ends together shows the full range. A benefit worth $1,400 at 62 becomes about $2,480 at 70 for the same worker — a monthly figure roughly 77 percent larger, driven entirely by the timing of the claim rather than any change in earnings. That spread is why the claiming decision carries more weight than almost any other single choice a retiree controls, and why financial planners spend so much time on it.
In practice, a large share of workers still claim at or near 62, often out of necessity or uncertainty about how long they will live. Surveys of new beneficiaries show early claiming remains common even as full retirement age has risen, which means many retirees lock in the roughly 30 percent reduction without fully weighing the alternative. Recognizing that the figure is permanent, compounds through every future cost-of-living adjustment, and shapes a survivor’s benefit is what turns the claiming age from a default into a deliberate choice. For a worker who can bridge a few years with savings or part-time income, even delaying from 62 to full retirement age erases the reduction entirely and restores the full benefit for life.
When Claiming Early Still Makes Sense
A permanently smaller check is not automatically the wrong choice. A retiree in poor health or with a family history of shorter lifespans may collect more total dollars by starting at 62, since the break-even age where waiting pulls ahead typically falls somewhere in a person’s late seventies or early eighties. Someone who has already stopped working and has no other income bridge may simply need the money now, regardless of the long-run math.
Continuing to work while claiming early carries its own cost. Before full retirement age, the Social Security earnings test withholds one dollar of benefits for every two dollars earned above an annual limit, though the withheld amounts are restored later through a higher recalculated benefit. A retiree who files at 62 but keeps a paycheck can see much of the early benefit temporarily held back, blunting the appeal of claiming while still employed.
The decision reaches beyond one person’s checkbook. Because a survivor benefit is based on what the higher-earning spouse was receiving, an early claim by that spouse permanently lowers the amount a widow or widower can later collect. For married couples, the question is rarely just when one person wants to retire, but which claiming ages leave the household — and the survivor who outlives the other — with the most secure income for the longest stretch.
