The average benefit for people aged 70 is $2,274.68 per month as of December 2025, according to the Social Security Administration (SSA). Age 70 is the finish line for Social Security growth because credits stop accruing once you reach your 70th birthday. While you're free to wait longer to claim, there's no financial incentive to doing so.

Waiting past full retirement age (FRA) lets you earn delayed retirement credits. If your FRA is 67, these credits add 8% to your benefit for every year you delay. This mechanic allows patient claimants to max out delayed retirement credits once they reach age 70.

The average retirement benefit at 70 reflects everyone who is 70 now, including those who claimed earlier. It's a blend of people who waited and those who claimed as early as age 62. Here's how the average breaks down by gender as of December 2025:

The average check for 70-year-old men is $2,529.62, while the average among women is $2,024.08, a gap of $505.54 per month. A 2.8% cost-of-living adjustment (COLA) took effect in 2026, which adds about $64 a month on top of that average.

How delaying Social Security affects your checks

Delaying until age 70 is often a fit for those in good health or with family longevity. If you live an average lifespan, you tend to receive roughly the same total regardless of when you claim. Most people reach the break-even point around age 82 to 83.

According to the SSA, a 65-year-old man is expected to live about 18 more years, while a woman of the same age is expected to live about 21 more years. The SSA calculates your benefit using an average of your monthly wages across your 35 highest-earning years.

Earlier wages are adjusted for inflation and run through the primary insurance amount (PIA) formula. FRA ranges from 66 to 67, depending on your birth year, and it's 67 for everyone born in 1960 or later.

If your FRA is 67, you earn a maximum 24% delayed retirement credit at age 70. For those with an FRA of 66, the maximum increase is 32%. This larger benefit also provides a higher survivor benefit for your spouse after you pass away, as that benefit is worth up to 100% of the amount you were receiving or eligible for at the time of your death.

Social Security was designed to replace only 40% of your pre-retirement income. Most retirees need significantly more than that to cover their costs, and the age-70 benefit covers about 44% of typical senior spending. This leaves a gap to be filled by savings or other income.

Your actual check depends on your work history and claiming age, but age 70 serves as the absolute ceiling for your monthly benefit growth.

Waiting to claim Social Security until 70 isn't always the best move

Claiming Social Security at 70 may get you the largest lifetime benefit if you expect to live into your mid-80s or beyond. But those with shorter life expectancies might get a larger lifetime benefit by applying earlier, possibly as soon as they become eligible for checks at age 62.

Claiming Social Security earlier can also make sense if you cannot afford to pay for your retirement expenses on your own until age 70. If you have a health issue, you're forced to retire early to care for a sick family member, or you simply don't have a lot in personal savings, you might prefer to apply earlier, even if it means settling for a smaller lifetime benefit.

Married individuals whose spouse has significantly outearned them often don't gain much by waiting to apply for benefits, either. In that case, claiming as soon as they become eligible could be the better move. Their Social Security checks will give the household some income, allowing their spouse to delay their own benefit application until they qualify for larger checks. Then, when the higher-earning spouse applies for Social Security, the lower-earning spouse can switch to a spousal benefit if that's worth more than their own retirement benefit.
