2027 Social Security COLA: Early Estimate Points to 3.8%

Seniors watching their Social Security checks have an early read on next year's raise, and it is running higher than this year's. The Senior Citizens League, a nonpartisan advocacy group that tracks the cost-of-living adjustment month by month, now estimates the 2027 COLA at 3.8 percent as of its mid-June 2026 update. That would be a full percentage point above the 2.8 percent increase that took effect in January 2026.

One important caveat up front: 3.8 percent is an estimate, not the real number. The official 2027 COLA does not exist yet and will not until the Social Security Administration announces it in October 2026. The sections below explain where that estimate comes from and what a raise this size would mean for your budget once the real number lands.

What the estimate says right now

The Senior Citizens League publishes a running COLA forecast and revises it every month as new inflation data comes in. Its latest estimate is 3.8 percent, nudged down from 3.9 percent in May 2026. Because the forecast moves with inflation through the summer, treat it as a best current guess rather than a promise. It will change again before the real number is set.

What pushed the 2027 estimate above this year's 2.8 percent is a pickup in inflation during 2026. The most recent inflation report available, for May 2026, showed the index that drives the COLA, called CPI-W, up 4.4 percent from a year earlier. When prices reaccelerate, the projected COLA rises with them.

When the official number comes out

By law, the COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W, published by the Bureau of Labor Statistics. Social Security compares the average of that index for July, August, and September against the same three months a year earlier. The size of that change is the COLA.

That measurement window for 2027 only just opened; July 2026 is the first of the three months that count. The Social Security Administration typically announces the final figure in mid-October, effective with January checks. So the official 2027 COLA is still months away, and any number you see before then, including 3.8 percent, is a projection.

What a 3.8 percent raise would mean in dollars

The average retired worker collected $2,071 a month at the start of 2026, after the 2.8 percent raise added about $56. If the 3.8 percent estimate holds, the math looks like this.

Your own increase depends on your own benefit, since the COLA is a percentage. A larger check gets a larger dollar raise, and a smaller check gets a smaller one.

The catch: Medicare could eat into it

A COLA is not quite the raise it looks like, because most retirees have their Medicare Part B premium pulled straight out of their Social Security check. When that premium rises, it reduces the net increase you actually see.

The standard Part B premium is $202.90 a month in 2026. The Medicare Trustees, in their June 2026 report, projected the 2027 premium at about $209.50, an increase of roughly $6.60 a month. That projection is not final either; Medicare announces the official 2027 premium in November 2026, and it has often come in higher than the Trustees estimate. If money is tight, it is worth checking whether you qualify for Medicare Savings Programs and Extra Help, which can cover that Part B premium entirely.

Why many seniors say the raise still is not enough

Even a 3.8 percent COLA would leave a lot of retirees feeling behind, and the data backs them up. The Senior Citizens League's 2026 research found that Social Security benefits have lost about 13.7 percent of their buying power since 2016. Looking back further, COLAs since 2000 have raised benefits by roughly 64 percent, while the costs seniors actually face have climbed about 130 percent, close to double.

Part of the reason is how the COLA is measured. CPI-W tracks the spending of working-age wage earners, not retirees, who spend more of their money on health care and housing, two categories that tend to rise faster. An experimental index built around older adults, called CPI-E, usually runs higher than CPI-W, which is why some advocates want the COLA switched to it.

What you should do now

There is nothing to sign up for; the COLA is applied automatically. The practical steps are simple: watch for the official announcement in October 2026, do not budget around the 3.8 percent estimate as if it were locked in, and if you are stretched, look into the benefit programs that reduce Medicare and everyday costs. A raise you have not seen yet is not money you can count on.
