Every year you wait between 62 and 70, your monthly check gets bigger. Whether waiting pays off for you depends on how long you live, what you'd do with the money in the meantime, and a few things no calculator can see. Start with the numbers, then read what's below them.

Your monthly benefit at each claiming age
How the three strategies compare over time
Fixed assumption: a 2.5% annual cost-of-living adjustment on every claiming age, in line with the SSA's long-range assumption and recent COLAs.
This is an educational illustration, not a projection of your actual Social Security benefit or a recommendation about when to claim. Get your real estimate at ssa.gov and talk to your advisor and tax professional before deciding. This tool assumes a full retirement age of 67 and a 2.5% annual cost-of-living adjustment applied to every claiming age, so dollar figures are future dollars, not today's purchasing power. It does not include taxes or the earnings test, and the assumed return is a comparison yardstick, not a forecast. Everything is calculated in your browser. Nothing you enter is sent or stored anywhere.
The math above treats claiming age as a numbers problem. For most of the retirees I sit down with, it isn't only that. Here's what else belongs in the decision.
If you claim before your full retirement age and keep earning a paycheck, Social Security withholds part of your benefit once your earnings pass the annual limit. You get that money back later through a recalculated benefit, but the check you were counting on shrinks now. If you're still earning a solid income, claiming early often accomplishes very little.
A bigger check at 70 is worth nothing if the years between 62 and 70 are lean and stressful. If claiming early is the difference between covering your life and draining accounts you'd rather leave alone, that belongs in the decision. The goal is a claiming age that fits your income picture, not the one that wins on a spreadsheet.
The breakeven age above is the whole tradeoff in one number. Live well past it and waiting was the better call. If your health or your family history suggests you may not, claiming earlier can be the sound choice, whatever the chart says. Nobody knows their own number. You can still make a thoughtful guess.
When one spouse dies, the survivor keeps the larger of the two benefits. That means the higher earner's claiming age sets the check that whichever of you lives longer will receive, possibly for decades. Even when the higher earner's own breakeven looks unappealing, waiting can make sense as protection for a surviving spouse.
Depending on your other income, up to 85% of your Social Security benefit can be subject to federal income tax. The timing of your claim interacts with withdrawals from retirement accounts, and coordinating the two can change what you actually keep. This is worth mapping out with your tax professional before you file.
Social Security is one of the few income sources you can't outlive that also adjusts for inflation every year. A larger starting benefit means every future cost-of-living adjustment is applied to a bigger base. The chart above builds this in with a 2.5% annual COLA on every strategy, and a later start means each year's raise lands on a bigger check. If most of your other income comes from savings, that built-in protection carries extra weight.
A dollar that arrives at 62 gets eight more years to do something for you than a dollar that arrives at 70. It could grow in an account, pay down a debt, or spare you from spending your own savings. The slider is the price you put on that head start, what an economist would call the opportunity cost of waiting.
To keep the comparison fair, the tool credits every check, at every claiming age, with growth at your chosen rate from the month it lands. That's a comparison device, not a prediction. Few people invest their Social Security checks, and nothing here assumes you would. Crediting the growth is simply the cleanest way to measure what eight years of that money compounding, versus not, costs you.
At higher assumed rates, the chart can show claiming at 62 staying ahead for a very long time, sometimes past any reasonable lifespan. That result is correct, and it deserves a caveat. The increase you get by waiting is set by law. It arrives whether markets rise or fall, and it lasts as long as you do. An assumed return is just that: assumed, and comparing the two means weighing a certain outcome against an uncertain one.
Two things the slider glosses over, worth being upfront about rather than treated as settled:
Taxes. Every dollar here is pre-tax, and retirement dollars aren't taxed alike. No more than 85% of a Social Security check is taxable, while a Traditional IRA withdrawal is ordinary income to the last dollar. The tool treats them as apples to apples, and in practice they aren't quite.
One smooth rate. Markets don't deliver a steady 6% a year, and the math here pretends they do. The higher the rate you set, the more the early-claiming case depends on strong returns showing up year after year without a rough stretch. The raise for waiting is written into the benefit formula instead.
Questions about how this fits your situation? That's exactly what a first call is for.
Not automatically. Claiming at 62 fits people who need the income now, have health reasons to doubt a long retirement, or have a spouse whose larger benefit will carry the household later. It becomes a mistake when it's chosen by default, without weighing longevity, taxes, and survivor benefits first. The sections above walk through each of those.
It's the age where the cumulative value of waiting overtakes the cumulative value of claiming early. Live past it and delaying paid off; fall short and the early claim won. This calculator also lets you credit early checks with investment growth, which pushes the breakeven age later than most calculators show.
Because a dollar that arrives at 62 has eight more years to be useful than a dollar that arrives at 70. Most calculators ignore that head start and compare raw totals. This one credits every check with growth from the month it lands, so claiming early gets fair credit for time. Set the return to 0% to see the plain comparison.
It can, in a lasting way. When one spouse dies, the survivor keeps the larger of the two checks, so the higher earner's claiming age sets the benefit the surviving spouse may receive for decades. For married couples, that protection often outweighs either person's individual breakeven math.
It can be. Depending on your other income, up to 85% of your benefit may be subject to federal income tax, and withdrawals from retirement accounts feed the formula that decides how much. Coordinating your claiming age with those withdrawals is a conversation for you, your advisor, and your tax professional together.
Almost always. Everything is handled virtually, so where you live is rarely a barrier. The only exception is a handful of states where I'm not registered yet, and if that's you, I'll tell you on our first call.

Claiming age is one piece of a retirement income plan. A short call is enough to see whether the rest of yours holds together.
