One of the most consequential retirement choices is when to start Social Security, anywhere from age 62 to 70. The decision permanently sets your monthly benefit and can swing your lifetime income by tens of thousands of dollars. Weighing the trade-offs helps you claim at the age that fits your health, finances, and family.

The mechanics of claiming early or late

Claiming before your full retirement age reduces your benefit by up to 30 percent for someone whose full age is 67 and who claims at 62. Waiting past full retirement age earns delayed retirement credits of about 8 percent per year until age 70, when the benefit maxes out. For a full retirement age of 67, that means a benefit at 70 roughly 24 percent larger than at 67 and about 77 percent larger than at 62. There is no additional increase for waiting beyond 70.

The break-even framework

Claiming early gives you smaller checks sooner, while delaying gives larger checks later, and the break-even age is where the totals cross. For many people the break-even falls in the late 70s or early 80s, so living beyond that favors having delayed. This makes the decision partly a bet on longevity and family health history. Because the larger benefit is also inflation-adjusted, delaying provides valuable insurance against outliving your money.

The earnings test before full retirement age

If you claim before full retirement age and keep working, the earnings test temporarily withholds some benefits once your wages exceed an annual limit, which was 23,400 dollars in 2025. The withheld amount is not truly lost, because your benefit is recalculated upward once you reach full retirement age. Still, working while collecting an early benefit can make claiming early far less attractive. The test disappears entirely once you reach full retirement age.

Coordinating with a spouse

For married couples, the higher earner's claiming age also sets the survivor benefit, so delaying can protect a surviving spouse for life. A common strategy has the higher earner delay to 70 while the lower earner claims earlier to provide some income. Health, other savings, and each spouse's life expectancy all factor into the plan. Viewing the decision as a household one, rather than two separate choices, usually leads to better outcomes.

Someone with a full-retirement-age benefit of 2,000 dollars a month would receive about 1,400 dollars if they claim at 62 but roughly 2,480 dollars if they wait until 70. Over a long retirement, that larger inflation-adjusted check can add up to substantially more lifetime income.

Key takeaways

  • Claiming at 62 can cut your benefit by up to 30 percent versus your full retirement age.
  • Delaying past full retirement age adds about 8 percent per year until 70.
  • Break-even ages often land in the late 70s or early 80s, making longevity central.
  • For couples, the higher earner's claim age sets the survivor benefit for life.

Common mistakes

FAQ

Is it always better to wait until 70?

No. Delaying rewards longevity, but poor health, an urgent need for income, or being the lower earner in a couple can make claiming earlier the right call.

Can I change my mind after claiming?

You can withdraw an application within 12 months by repaying benefits, or suspend benefits at full retirement age to earn delayed credits again.
