Claim Social Security at 62, the earliest age allowed, and the agency locks your check in at 70 percent of what you would have received at your full retirement age of 67. Not for a few years. Seventy percent, for as long as you live.
Plenty of people do not get a clean choice in the matter. A layoff in your late fifties, a health scare, a spouse who already needs care at home. Sometimes 62 is simply the year the math has to work, and that does not make the decision wrong.
Most of the regret that shows up later has nothing to do with the number on that first deposit. It shows up in six other places nobody mentions at the time you sign the paperwork.
The reduction is permanent, not temporary
If you were born in 1960 or later, your full retirement age is 67. Start your benefit at 62 and Social Security pays 70 percent of your full retirement age amount instead of 100 percent. There is no recalculation built in. Nothing adjusts that percentage back upward once you reach 67 simply because you wish you had waited.
The average retired worker received $2,071 a month in January 2026, after that year's cost of living increase. Apply the 62-year-old's 70 percent factor to that same figure and the monthly check drops to roughly $1,450, a gap of about $621 every single month. Stretch that gap across twenty or thirty years of retirement and the lifetime difference runs well into six figures for plenty of households.
Your own numbers will land somewhere else depending on your earnings history, but the 70 percent factor itself does not change. It applies the same way to a $1,200 benefit as it does to a $3,500 one, and it follows you for the rest of your life.
Working before full retirement age triggers withholding
A lot of people claim at 62 planning to keep working part time on the side. Social Security allows that, but only up to a point. Earn more than $24,480 in 2026 while collecting benefits before full retirement age, and the agency withholds $1 in benefits for every $2 you earn above that limit.
Someone who picks up part time consulting work and earns $40,000 in a year while collecting reduced benefits would clear about $15,520 over that limit. Half of that, roughly $7,760, gets withheld from their Social Security payments for the year, stacked directly on top of the permanent reduction already built into their check from claiming early.
That withheld money is not gone forever. Once you reach full retirement age, Social Security recalculates your benefit to credit you for the months payments were withheld, which raises your check somewhat going forward. But there is no lump sum refund, and the math rarely makes up for the income you actually needed in the years you were short on cash.
A paycheck can also make your benefit taxable
The earnings test is not the only cost of working after you claim, and it is not the same cost. If your combined income, your adjusted gross income plus half your Social Security benefit, tops $25,000 as a single filer or $32,000 filing jointly, the IRS can tax up to 85 percent of your benefit. That is a separate hit, calculated by the IRS, not Social Security, and it applies on top of whatever the earnings test already withheld.
Those thresholds were set in 1983 and 1993 and have never been adjusted for inflation. A paycheck, a pension, or even interest income from savings can push you over the line easily, especially since the formula already counts half of your Social Security benefit toward the total before anything else is added. Plenty of people who claim at 62 assuming a tax-free check end up paying federal income tax on a chunk of it the very first year, simply because they were still earning ordinary income at the same time.
This has nothing to do with whether your benefit gets withheld and later credited back at full retirement age. Taxed income is gone, the same as any other line on your return.
Your survivors inherit the smaller number
Claiming early does not stop at your own check. It follows you after you die. Social Security caps a surviving spouse's benefit using what is known as the widow limit, the greater of 82.5 percent of your full retirement age benefit or the reduced amount you were actually receiving at the time of your death. Claim at 62, and that smaller, reduced amount becomes the ceiling your surviving spouse lives under for the rest of their own life, in most cases.
This is worth separating from a living spouse's own spousal benefit, which works differently. A spouse who is still alive and collecting on your record can get up to 50 percent of your full retirement age amount if they wait until their own full retirement age, or as little as 32.5 percent if they claim at 62, and that percentage is governed by the spouse's own age, not yours. The widow limit only comes into play once you are gone.
This is the piece people skip past fastest when they are deciding at 62, because the effect lands on someone else's check, years or decades down the road. By the time it matters, the original decision is long settled and impossible to revisit.
Your future raises shrink along with everything else
Social Security benefits increased by 2.8 percent in 2026, the latest cost of living adjustment tied to inflation. That adjustment is a percentage, not a flat dollar amount, which means the dollar value of your raise is calculated directly off whatever your monthly check already is.
A retiree collecting the 2026 average benefit of $2,071 a month gained about $58 from that year's adjustment. Someone collecting 70 percent of that same figure, the result of having claimed at 62, gained only about $41 from the identical 2.8 percent increase. That $17 gap repeats every single year a cost of living adjustment is issued, compounding on an already smaller base for the rest of that person's life.
The permanent reduction is one cost. The smaller raises stacked on top of it for decades afterward are a second, separate cost, and they rarely get mentioned in the same conversation.
Claiming early is a bet against your own longevity
The reduction built into claiming at 62 is designed to be roughly neutral over an average lifespan. Live to the average life expectancy for your birth year, and the smaller monthly checks for more years should add up to about the same lifetime total as larger checks for fewer years. The bet only works in your favor if you die close to that average, or earlier.
Social Security's own consumer guidance points out that married couples at age 65 today have at least a 50/50 chance one spouse will live past 90, and that one out of every three 65-year-olds will reach at least 90. Those are not fringe odds. They describe a meaningful share of the people reading this.
Claim at 62 assuming you will not see your mid eighties, and live well past them instead, and the smaller checks you locked in keep costing you for decades longer than the math behind that decision ever accounted for. Nobody plans to be wrong about their own life expectancy. Plenty of people are.
You only get 12 months to change your mind
Social Security gives early claimants a narrow window to reverse course. You can withdraw your application within 12 months of when your benefits began, but only once in your lifetime, and only after repaying every dollar you and your family received, including any amount withheld for Medicare premiums.
Miss that window, and the choice is permanent. The only other lever available is voluntarily suspending your payments once you reach full retirement age, which earns delayed retirement credits from that point forward. That adds to your already reduced benefit. It does not erase the cut you took for claiming early in the first place.
Twelve months sounds like plenty of runway when you are signing up at 62. For most people, the realization that the decision actually mattered does not arrive until well after that window has already closed, often once a job offer comes through, a spouse's situation changes, or a second look at the math makes the original timing feel rushed.
