Social Security's 2027 COLA Is 3.6% - Here's How Much the Average Check Is Going Up

Social Security is one of the most heavily relied upon senior benefits today. There are many older Americans who live on Social Security alone, or whose benefits cover the majority of their living expenses. That's what makes Social Security's cost-of-living adjustments, or COLAs, so important.

Each year, Social Security benefits are eligible for a COLA automatically. The purpose of COLAs is to ensure that benefits are able to keep pace with inflation.

The Social Security Administration just announced an official 3.6% COLA for 2027, and here's what it means for the average benefit.

The average Social Security check could rise by about $75

A 3.6% Social Security COLA could add a significant amount of money to some people's retirement paychecks. The average monthly Social Security benefit today collected by retirees is about $2,088. So a 3.6% COLA results in a monthly boost of roughly $75. On an annual basis, that's an extra $900 a year for the typical beneficiary.

Of course, the exact amount of money your Social Security check rises in 2027 will depend on what your monthly benefit looks like. If you receive $2,500 a month, for example, you can expect a boost of $90. If your benefit is only $1,800, you can expect about $65 more per month.

How Social Security COLAs are calculated

Social Security COLAs are calculated based on changes to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) during the third quarter of the year. When there's a rise in the CPI-W, Social Security benefits go up.

There's no such thing as a negative COLA, though. If the CPI-W shows a decrease in annual inflation during the third quarter of the year, benefits simply stay where they are.

Why it may be too soon to calculate your raise in full

Now that the 2027 Social Security COLA is official, you may be gearing up to apply that 3.6% raise to your monthly check and see how much your benefits will increase. But it may be too soon to run that calculation if you're on Medicare.

Seniors who are enrolled in Medicare and Social Security at the same time pay for Part B out of their monthly benefits. If there's an increase in the cost of Part B, it automatically eats into your COLA.

In 2026, the cost of Medicare Part B increased by $17.90 per month. We don't know how much the cost of Part B will increase in 2027, as that information has not yet been released.

But let's say the cost of Part B increases by $10 next year. You'll need to then deduct that $10 from whatever amount your COLA would've otherwise given you. If you collect the average Social Security benefit and would've been looking at a $75 raise, a $10 Medicare increase would leave you with $65 more per month instead.

What your Social Security COLA will and will not do for your finances

It's important to have realistic expectations for your upcoming Social Security COLA. While a 3.6% raise may sound nice, one thing to remember is that COLAs are simply designed to match inflation. They're not supposed to improve your financial situation as a whole.

Furthermore, COLAs are based on previous inflation data. If inflation rises at a faster rate than 3.6% in 2027, your Social Security checks could lose buying power even with a generous raise. It's important to recognize this going into the new year so you know what to expect.

Also, if costs don't rise right away in 2027, you may have an opportunity to put some or even all of your 3.6% COLA into savings for a rainy day. That's worth doing in case inflation picks up during the year, or you end up facing a surprise bill.

Bottom line

Social Security may be a big part of your retirement plan. And you may be relieved to know that your benefits should be getting a sizable boost in the new year.

But it's important to realize that your 3.6% COLA could be whittled down by Medicare Part B hikes and higher costs in the new year. So if you're having trouble making ends meet on Social Security right now, you may want to take steps to improve your financial picture rather than rely on your COLA to do all of the heavy lifting.

Working part-time in 2027 could put a lot more money in your pocket each month than the raise your COLA gives you. And if you're unable to work, you could instead try trimming expenses or even moving to a part of the country where your Social Security checks can go further. These choices could help you get to a better place financially if you're living mostly or solely on Social Security today.
