When to claim Social Security, if you stop work early

Social Security is one of the few incomes that lasts for life and rises with inflation. When you start it is your choice, any month from 62 to 70, and it's hard to undo later.

People who reach FIRE often stop work long before 62. That changes the picture in two ways: your benefit may be smaller than you'd guess, and your savings can carry you while you wait.

This is general education, not advice. Social Security rules have details this page can't cover. Check your own record and numbers at SSA.gov, and talk to a licensed professional before you decide.

The three ages that matter

• 62: the earliest. You can start as early as 62, but the check is smaller for life. For anyone born in 1960 or later, starting at 62 pays about 30% less than waiting for full retirement age (SSA).
• 67: full retirement age. For anyone born in 1960 or later, this is the age when you get your full benefit, the amount SSA calls your primary insurance amount (SSA).
• 70: the most you can get. Each year you wait past full retirement age adds 8% to your benefit. The increases stop at 70 (SSA).

So the same work record can pay about 70% at 62, 100% at 67 and 124% at 70. Each year's cost-of-living increase is added on top, whichever age you choose. For 2026 it was 2.8% (SSA).

What stopping early does to your benefit

Two rules matter most for early retirees.

You need 40 credits to qualify. You earn up to four a year. In 2026, each $1,890 of earnings counts as one credit, so $7,560 earns all four (SSA). That's about ten years of work. Extra credits don't raise your benefit.

Your benefit is based on your highest 35 years. SSA adjusts each year's earnings for wage growth, then averages your top 35 years (SSA). If you worked fewer than 35 years, the missing years count as zero.

That sounds harsh, but the formula softens it. It replaces 90% of the first slice of your average earnings, 32% of the next slice, and 15% above that (SSA). Your first dollars of earnings count the most.

A worked example

Take someone whose pay, adjusted for wage growth, was $70,000 every year they worked. Using SSA's 2026 formula, their full benefit at 67 would be about:

• 35 years of work: $2,612 a month
• 25 years of work: $2,079 a month
• 20 years of work: $1,812 a month

Twenty years of work earns about 69% of the 35-year benefit. Stopping 15 years early costs less than you might fear.

For the 20-year worker, starting at 62 would pay about $1,268 a month, and waiting until 70 about $2,247.

Worked out with the 2026 bend points ($1,286 and $7,749) and SSA's rounding. These figures are in today's dollars and leave out future law changes. Real records are messier, so treat this as a sketch.

Your own estimate is a better starting point than any example. A free my Social Security account shows your earnings record and estimates at 62, at full retirement age and at 70. Check the earnings record too: a missing year counts as zero.

The case for starting earlier

• Your health or family history suggests a shorter life. Waiting only pays off if you live long enough to collect the bigger checks.
• You need the income. If the choice is between claiming at 62 and selling investments in a bad year, or taking on debt, an earlier start can be the calmer path.
• You're single, with no one relying on your benefit after you. Waiting helps a surviving spouse most (see below).

A simple way to compare: someone who starts at 62 collects five years of smaller checks before someone who waits until 67 gets their first check. Counting dollars only, the person who waited catches up at about 78 and 8 months. Comparing 67 with 70, the catch-up comes at about 82 and a half. (Our arithmetic from SSA's percentages. It leaves out taxes and investment returns, and both people get the same yearly increases.)

The case for waiting

• You might live a long time. A bigger check that lasts for life and keeps up with inflation protects you most if you live into your 90s. SSA has a life expectancy calculator that gives a rough average for your age and sex.
• You're married, and you're the higher earner. A widow or widower who waits until their own full retirement age can receive up to 100% of their late spouse's benefit (SSA). When the higher earner waits, the survivor's check is bigger too, possibly for decades.
• Your savings can bridge the gap. Many early retirees spend more from savings in their 60s so they can start Social Security later. In effect, they're using savings to buy a bigger lifetime income.

If you're married

A spouse can receive up to 50% of the worker's full benefit, if the spouse waits until their own full retirement age. Starting a spouse's benefit at 62 cuts it to 32.5% of the worker's full benefit (SSA). You generally need to have been married at least a year. An ex-spouse can qualify after 10 years of marriage (SSA).

If one of you earned much more, the two claiming ages work together. A common pattern is for the lower earner to start earlier and the higher earner to wait, but every couple's numbers are different. Talking to your partner about FIRE has more on planning together.

If you'll still earn some money

If you start benefits before full retirement age and keep working, the earnings test can hold back part of your check. In 2026, SSA holds back $1 for every $2 you earn above $24,480. In the year you reach full retirement age, it's $1 for every $3 above $65,160, counting only the months before the month you reach it (SSA). Only pay from work and self-employment counts. Pensions, annuities, interest and investment income don't (SSA).

The money isn't lost. Once you reach full retirement age, SSA raises your check to make up for the months it held back (SSA). Still, if you plan to earn a little in early retirement, it's worth knowing before you claim.

Taxes

Part of your benefit can be taxable, depending on your other income (IRS). Once your income, plus half your benefit, passes $25,000 (single) or $32,000 (married, filing jointly), up to 50% of your benefit counts as taxable income. Above $34,000 or $44,000, up to 85% does. These thresholds aren't adjusted for inflation (2026 Trustees Report summary).

How you draw on your accounts in your 60s affects this. Which account do you spend first? walks through the order.

Public servants with a pension

The Social Security Fairness Act ended two rules, the Windfall Elimination Provision and the Government Pension Offset. Starting with benefits for January 2024, they no longer reduce benefits for people with a pension from work that didn't pay into Social Security (SSA). If you held off applying because of those rules, SSA says you may need to file an application.

Most state and local workers, about 72%, pay into Social Security and were never affected (SSA). FIRE on a public servant salary covers pensions in more depth.

What about the trust fund?

The 2026 Trustees Report projects that the combined Social Security trust funds can pay full benefits until the third quarter of 2034. After that, incoming taxes would still cover about 83% of scheduled benefits, unless Congress changes the law (SSA).

Some people plan with a lower figure, such as 80% of their estimate, to leave room for change. That's a planning cushion, not a prediction.

Medicare is a separate clock

Medicare usually starts at 65, whenever you claim Social Security. Enrollment is automatic only if you start Social Security at least 4 months before you turn 65. Otherwise, you sign up yourself (Medicare.gov). SSA advises applying within three months of turning 65, or Part B and Part D may cost more (SSA). Different rules can apply if you're covered through a current job. Medicare in plain English explains the parts.

Questions to ask yourself

1. What does my own estimate say at 62, 67 and 70?
2. How long did my parents and grandparents live, and how is my health?
3. If I'm married, which of us earned more, and who is likely to live longer?
4. Can my savings comfortably cover the years before I claim?
5. Will I still be earning money before full retirement age?

There's no single right age. Some people claim at 62 and sleep well. Others wait until 70 because a bigger lifetime check gives them peace of mind. Both are reasonable choices.
