If you were born in 1960 or later, your full retirement age is 67. Take Social Security at 62 and you accept roughly a 30% cut to your monthly benefit, permanently. That cut drives most of what you hear about waiting.

Here's the spread in real numbers. Say your full retirement age benefit is $1,800 a month. At 62 it becomes $1,260 a month. Wait until 70 and it climbs to $2,232 a month. That's close to a thousand dollars a month between the earliest and the latest filing date.

The break-even math says that if you file at 62 instead of 67, the person who waited pulls ahead in total dollars collected somewhere around age 78 or 79. The Social Security Administration removed its break-even calculator from its website, because too many people were using it in isolation and making poor filing decisions with it. The chart ignores cost of living adjustments, spousal benefits, taxes, and investment returns. It's a starting point. Here are seven reasons the ending can look different.

Two reasons that come down to necessity

The first is health. If your health is already poor, or your family history points to a shorter lifespan, the whole calculation shifts toward taking benefits as soon as you can. The Social Security Administration's actuarial tables put average life expectancy for someone who has already reached 62 at age 84. That's an average. If your parents died in their sixties, or you're managing a chronic condition, or longevity just doesn't run in your family, your number may look nothing like 84. Moving that assumption by three years is enough to flip the answer. You don't need a terminal diagnosis for this to apply, only an honest read on your own health. You can't spend money you never received.

The second is losing the ability to work. A 2024 MassMutual survey put the average retirement age in the US at 62, and for a lot of those people 62 was never the plan. Layoffs, age discrimination, the physical demands of a job, and industry changes push people out of the workforce early. If you're 62 and out of work, burning through savings to hold out for a bigger check can do more long-term damage than accepting the reduction now. Social Security was designed as a safety net. If the work available to you pays less than what you were making, the benefit can bridge that gap and leave your retirement accounts alone.

Filing early can keep your retirement accounts invested

Take Social Security at 62, use it to cover living expenses, and you can leave more of your 401(k) and IRA money invested instead of drawing it down. Every year you don't pull from those accounts is another year of compounding.

The case for waiting is an 8% increase for every year you delay past full retirement age, essentially a guaranteed, inflation-adjusted return. If your portfolio averages more than that, the math can favor filing early and letting the investments ride. Vanguard published a study in 2025 finding that for people with little to no risk of outliving their assets, claiming at 62 produced higher median wealth through their mid to late eighties.

Be careful how far you take this. There's advice circulating that says to file at 62 and put the whole check into the stock market. Market returns aren't guaranteed, and sequence of returns risk, where the market drops the year you retire or right after, is very real. The point is leaving the investments you already hold in place and giving them more time to grow.

Married couples decide this together

If you're the lower-earning spouse, filing at 62 brings income into the household while the higher earner delays. Spousal benefits can provide up to 50% of the higher earner's full retirement age benefit. When there's a wide earnings gap, the lower earner's own benefit probably won't exceed that 50% even after delaying, so waiting buys them almost nothing. Filing early puts money in the household now and lets the high earner push toward 70, which maximizes their benefit and the eventual survivor benefit.

The survivor piece is one of the strongest arguments for filing early. If the higher earner has a serious health condition and may not live a long time, the lower-earning spouse filing early becomes an easy call. When the higher earner passes away, the survivor switches to the larger survivor benefit, which can be up to 100% of what the deceased spouse was receiving. Skip the early filing in that situation and you spend years collecting nothing while your spouse is alive. That money is simply gone. This takes some honest and uncomfortable conversations about health, and it can be worth tens of thousands of dollars over a lifetime.

Early filing as a market contingency

If you're retired, drawing down your portfolio, and the market takes a serious dive, filing early can be a lifesaver. Think back to 2008, or the dot-com crash in 2001. Selling stocks in those years meant locking in losses of 40% or 50% and doing permanent damage to a portfolio. Turning on Social Security during a downturn buys your investments time to recover without forcing you to sell into the drop.

None of this has to be your plan going in. You can retire intending to delay until 67 or 70 and keep filing at 62 in your back pocket as a contingency. If the market falls 40% the year you turn 63, having that option available could save your retirement.

The low-income window before RMDs

There's a stretch in early retirement, after you stop working and before required minimum distributions begin around 73 or 75, when your income is unusually low. If you have little coming in now and expect more later from a pension, annuity payments, or RMDs, filing during that window can mean paying little or even no tax on your benefits. Up to 85% of Social Security can be taxed depending on your combined income, so where the benefit lands in your income picture matters.

That same window is the ideal time for Roth conversions. You can use the benefit to cover monthly living expenses while you convert 401(k) or traditional IRA money into a Roth and pay little or nothing on the conversion. Once RMDs start and your income climbs, the window closes for good. What matters is how much you keep after taxes.

What the comment sections leave out

Read the comments under any Social Security video and you'll see people telling you to take it at 62. For plenty of them, that was the right call. The people who waited until 67 or 70 rarely show up to say so. Filing at 62 isn't automatically right for everyone, and neither is filing at 70. It depends on your health, your savings, your spouse's situation, your taxes, and what you want retirement to look like.

Set up a my Social Security account at ssa.gov and look at your projected benefit at 62, 67, and 70. If you're married, run the numbers as a couple. Time and health in your sixties have real value that never shows up on a spreadsheet, so use the math and an honest look at your own life, and don't decide on either one alone.
