The 2027 Social Security COLA Is Official. Here’s the Average Benefit at Every Age From 62 to 70.

It’s official. On Oct. 14, 2026, the Social Security Administration (SSA) announced a 3.6% cost-of-living adjustment (COLA) for every Social Security beneficiary effective in January 2027. This represents the largest increase in benefits since 2023.

How much extra money does a 3.6% adjustment provide? It depends on your current benefit, which, in turn, depends in large part on your age.

How the 3.6% Social Security COLA was calculated

The Social Security COLA is based on inflation. In particular, SSA uses an inflation metric called the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).

Note that the CPI-W doesn’t always exactly match the inflation number you might see in news reports. That’s because the CPI-W is based only on the expenditures of households where more than half of the household income comes from clerical or wage occupations and at least one of the household’s earners was employed for at least 37 weeks during the previous 12 months. The CPI-W population makes up around 30% of the total U.S. population.

SSA calculates the percentage difference between the CPI-W for the third quarter of the current year and the previous year, if any. The agency then rounds the result to the nearest 0.1% to get the final COLA amount.

The average benefit at every age — before and after the COLA

SSA publishes the average Social Security benefit by age twice per year, in June and December. The most recent data from the agency is from June 2026. The table below shows the latest average Social Security benefit by age, along with the impact that a 3.6% COLA will have on the benefit:

You probably noticed that the benefits both before and after the 3.6% COLA increase as age rises. One reason is that individuals who claim Social Security benefits before their full retirement age, which is now 67 for everyone, incur an early retirement penalty. Also, waiting to claim Social Security benefits after your full retirement age increases the amount you receive.

However, the averages in the table don’t just reflect those who retired at the ages shown. Social Security benefits also increase at older ages because people have received more COLAs over time.

Next year’s 3.6% COLA will boost the Social Security benefits of the average 62-year-old by $52.25 per month, or $627 for the full year. The average 70-year-old, on the other hand, will receive a benefit increase of $81.54 per month, or $978.48 for the year.

Two caveats

You can easily calculate how much extra money to expect in January with the 3.6% Social Security COLA. Simply multiply your current benefit amount by 0.036 to see how much the adjustment will increase your check. You can also multiply your current benefit by 1.036 to see what your new benefit will be next year.

However, you don’t have to do any calculations if you’re willing to wait a little while. SSA will send personalized notices in December with your exact 2027 benefit amount. Those notices from SSA will also include details on how much will be withheld for Medicare premiums.

There are also two caveats with the 2027 Social Security COLA. First, it might not be enough to fully offset seniors’ increased costs. Second, the extra money won’t arrive in time to cover the higher expenses seniors are already incurring.

Shannon Benton, executive director of The Senior Citizens League, summed it up by stating, “When inflation spikes due to a geopolitical event like the Iran war, seniors pay the price. Prices go up today, but benefits stay the same for months due to an outdated COLA methodology. Working people can request a raise or seek a higher-paying position, but seniors have to make lifestyle cuts or drain their savings until the next COLA.”

In short, the 2027 Social Security COLA is the biggest in years. But it might be too low and too late for many retirees.
