Social Security Break-Even Calculator

The most expensive guessing game in retirement

You get one decision, it’s permanent, and it can swing your lifetime income by well over $100,000. Claim Social Security at 62 and the checks start now but they’re smaller forever. Wait until 70 and every check is dramatically bigger, but you’ve given up eight years of payments to get there. There’s no do-over. Once you file, the amount is essentially locked in for life (cost-of-living adjustments aside).

That’s exactly what the calculator above sorts out. Punch in your estimated monthly benefit at 62 and at 70, straight from your my Social Security statement at SSA.gov, and it finds your break-even age: the age where waiting finally pulls ahead in total dollars collected.

What you actually get at 62, 67, and 70

For anyone born in 1960 or later, full retirement age (FRA) is 67. Your benefit at that age is called your primary insurance amount, and everything else is measured against it.

• Claim at 62: about 70% of your full benefit. The reduction is permanent and it stings. It stays with you for every check you’ll ever receive.
• Claim at 67 (FRA): 100%. No reduction, no bonus. This is also the age where the earnings test disappears, which matters if you’re still working.
• Claim at 70: about 124% of your full benefit. Each year you wait past FRA earns delayed retirement credits of roughly 8%, up to age 70. After 70 there’s no reason to wait, the credits stop.

Put dollars on it. With a $2,000 monthly benefit at FRA, that’s $1,400 at 62, $2,000 at 67, or $2,480 at 70. The age-70 check is 77% bigger than the age-62 check, every single month, for the rest of your life. Over a 20-year retirement that gap can easily exceed $100,000 in total benefits.

Let’s do the break-even math by hand

The idea is simple. Claiming early gives you a head start. Claiming late gives you bigger checks. The break-even age is where the bigger checks finally catch up with the head start.

Take the $2,000 FRA example. Claim at 62 and you collect $1,400 a month for the 96 months between 62 and 70. That’s $134,400 banked before the late claimer sees a dime. But from 70 on, the late claimer gets $1,080 more every month ($2,480 minus $1,400). Divide the head start by the monthly advantage: $134,400 ÷ $1,080 ≈ 124 months, or about 10.4 years. Add that to 70 and you get a break-even age of roughly 80.4.

The same arithmetic gives about 78 to 79 for 62 vs 67, and about 82 to 83 for 67 vs 70. Notice something useful: because cost-of-living adjustments apply as a percentage to every claiming age, COLAs don’t meaningfully move these crossover ages. The 2026 COLA was 2.8%, and it lifts the early and late checks proportionally, so the break-even math holds in today’s dollars either way.

Live past your break-even age and delaying wins. Die before it and claiming early wins. That’s the whole game, and the only input nobody can give you is how long you’ll live.

How the calculator works

The calculator runs the same comparison on your numbers instead of round examples. Enter your monthly benefit estimates at 62 and 70 (your SSA statement shows all three ages), optionally add a COLA assumption, and it computes cumulative lifetime totals at several ages plus your exact break-even point.

A few honest limitations. It compares single-person, cumulative dollars, before taxes. It doesn’t model spousal or survivor benefits, the taxation of benefits (up to 85% can be taxable depending on income), or the earnings test that withholds benefits if you claim before FRA while still working. For 2026, the earnings test withholds $1 for every $2 earned above $24,480 before FRA. Withheld benefits aren’t lost, SSA recalculates your payment at FRA, but claiming at 62 while earning a full salary rarely makes sense. Married couples should think especially hard about the survivor angle, which the next section covers.

The one factor that beats the break-even math

If you’re married, the higher earner’s claiming decision does double duty. A surviving spouse inherits the deceased spouse’s actual benefit, including all those delayed retirement credits. So the higher earner waiting until 70 doesn’t just raise their own check, it sets the survivor benefit the other spouse may live on for a decade or more.

Example: the higher earner’s FRA benefit is $3,000. Delay to 70 and it’s $3,720 a month. If the lower-earning spouse claimed $1,200 at 67, then when the higher earner passes, the survivor’s benefit steps up to $3,720. That single decision can be worth more than the entire break-even calculation for the higher earner’s own lifetime. For couples, the higher earner delaying is often the most powerful move on the board, even if that earner personally dies before break-even.

Spousal benefits while both spouses are alive work differently: a spouse can claim up to 50% of the other spouse’s FRA benefit (not the delayed amount). Worth knowing, but it’s the survivor benefit where delaying really pays.

When claiming early is the right call

Delaying isn’t for everyone, and the break-even framing can make it sound like waiting is always smarter. It isn’t. Claim early when your health or family history suggests a shorter life expectancy, when you need the income now and have no bridge savings, or when you’re the lower-earning spouse and the higher earner is the one delaying. There’s also a tax-planning angle some retirees use: claim early or delay strategically to create low-income years for Roth conversions before RMDs begin at 73. If you want to see what those forced withdrawals will look like when they do start, the RMD calculator lays out the amounts year by year. That’s genuinely sophisticated planning and worth discussing with a tax professional, because the interaction with Medicare premiums and benefit taxation gets complicated fast.

One more thing people get wrong: Dave Ramsey famously advises claiming at 62 and investing the difference. The math can work if you actually invest every dollar at a solid return and never touch it. In practice, almost nobody does. Be honest about which person you are before banking on that version.

Who this is for, and what to do next

This calculator is for anyone within about ten years of claiming who wants the trade-off in dollars instead of slogans. Pull your real estimates from your my Social Security account first, guesses make the output meaningless. Then run your numbers, note your break-even age, and weigh it against your health, your spouse’s situation, and whether you have savings to bridge the gap years.

If the decision feels close, that’s normal. It means the math isn’t deciding for you, and that’s fine. The math was never supposed to. It just tells you the price of each choice so you can make it with your eyes open. And if your employer is also offering you a pension-or-lump-sum choice, run that through the pension vs lump sum calculator as well, because a guaranteed monthly pension changes how much you need Social Security to cover.
