For most retirees, Social Security is the single largest source of guaranteed lifetime income they'll ever have. Yet the majority of Americans claim it without ever running the numbers — and that decision can cost them hundreds of thousands of dollars over the course of their retirement.
Here's what you need to know before you press the button.
How Your Benefit Is Calculated
Social Security doesn't just look at your last few paychecks. It looks at your 35 highest-earning years, adjusts them for wage growth, and averages them out to produce your Average Indexed Monthly Earnings, or AIME. That figure is then run through a formula to produce your Primary Insurance Amount — your PIA — which is the benefit you'd receive at your Full Retirement Age.
One important detail: if you worked fewer than 35 years, Social Security fills in the missing years with zeros. Time taken off to raise children, care for a family member, or start a business can pull your average down significantly. Understanding this number is the starting point for every claiming decision.
The Claiming Age Decision: 62 vs. 67 vs. 70
Here's where the stakes get real. Using a PIA of $2,800 per month as an example, here's what happens at each claiming age. Claim at 62 — the earliest possible age — and your benefit is permanently reduced by about 30%, dropping to roughly $1,960 per month. Claim at your Full Retirement Age of 67 and you receive the full $2,800. Wait until 70 and delayed retirement credits of 8% per year push your benefit to approximately $3,470 per month — for life.
That's a difference of more than $1,500 a month between the earliest and latest claiming ages. Over a 20-year retirement, that gap exceeds $360,000 in lifetime income. Too many people claim at 62 out of habit or fear without ever modeling what waiting would actually mean for their financial picture.
Spousal and Survivor Benefits — The Couples Piece
For married couples, Social Security has an additional layer that's often overlooked. A spouse can claim a benefit worth up to 50% of the higher earner's PIA — even with little or no work history of their own. Using the same $2,800 example, a non-working spouse could be entitled to up to $1,400 per month at their Full Retirement Age.
Survivor benefits add another dimension. When one spouse passes away, the surviving spouse receives the higher of the two benefits — not both combined. That means the higher earner's claiming decision doesn't just affect their own check. It sets the floor for what their spouse will receive, potentially for decades. Delaying to 70 can be as much about protecting a surviving spouse as maximizing your own income.
The Earnings Test and Tax Considerations
If you claim Social Security before your Full Retirement Age while still working, the earnings test applies. For every $2 you earn over the annual limit, Social Security withholds $1 in benefits. The withheld amount is eventually returned once you reach FRA — but the timing matters, and it can affect your overall strategy.
Taxation is another surprise for many retirees. Depending on your total income, up to 85% of your Social Security benefit can be subject to federal income tax. Withdrawals from traditional IRAs count toward the provisional income calculation that triggers this tax — but qualified Roth IRA withdrawals do not. The order in which you draw from your accounts in retirement can directly affect how much of your Social Security gets taxed.
The Break-Even Question
Delaying clearly produces a larger monthly benefit. But the real question is whether you'll live long enough to come out ahead. In a typical scenario, the break-even point between claiming at 62 versus 70 falls somewhere around age 80 to 81. If you're in good health with family longevity on your side, delaying often wins. If you have health concerns, claiming earlier can be the right call.
There is no universal right answer — which is exactly why this decision deserves a personalized analysis, not a guess.
