The 2027 Social Security Cost-of-Living Adjustment (COLA) is *projected* at 3.8%, but that number is a forecast, not a final figure. It comes from The Senior Citizens League, an advocacy group, and not from the Social Security Administration (SSA), which will not set the official rate until October 2026. A COLA is the annual raise that keeps Social Security benefits roughly in step with inflation. If the 3.8% estimate holds, it would top the 2026 raise by a full percentage point—but several other analysts predict a smaller number, so treat 3.8% as one plausible scenario, not a promise.

What the 3.8% number actually means
The 3.8% figure is a July 2026 prediction, published as inflation data rolled in. According to ConsumerAffairs reporting on the TSCL estimate, a 3.8% raise would lift the average retiree benefit by about $77 a month—from roughly $2,026 to $2,103.
That estimate is not an official determination. The SSA sets the real COLA using a specific inflation measure, and no forecast can lock in the result before the underlying data is final. Use the projection for planning ranges, not for budgeting exact dollars.
How the COLA is calculated
The COLA is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a government measure of prices paid by working households. Per the SSA, the adjustment equals the percent change in the CPI-W from the third quarter (July–September) of one year to the same quarter the next.
The U.S. Bureau of Labor Statistics calculates the CPI-W monthly. Because the 2027 COLA depends on July, August, and September 2026 data, the number can shift right up until those final readings arrive.
Why forecasts disagree
The 3.8% projection is not a consensus. As CNBC reported, estimates ran as high as 4.7% in June 2026 before inflation cooled and pushed projections down. Other groups land lower than TSCL.
AARP projects about 3.6%, per its 2027 COLA estimate page, while independent analyst Mary Johnson estimates 3.7%. The gap between forecasts is small, but it shows how sensitive the final figure is to a few months of data. For context, the official 2026 COLA is 2.8%. A 3.8% raise would be the largest since 2023.
When the official number arrives and who it affects
SSA is expected to announce the official 2027 COLA on October 14, 2026, with the change taking effect in January 2027 payments, according to CNBC Select. Until then, every published rate is an estimate.
The adjustment reaches a wide group. It applies to the roughly 75 million Americans who receive Social Security and Supplemental Security Income (SSI), including retirees, disabled workers, and survivors.
A higher COLA is not the same as a bigger raise
It helps to read a large COLA cautiously. A higher adjustment signals higher inflation—not stronger buying power.
TSCL notes that Social Security benefits have lost purchasing power over the years even as COLAs have been paid. Two factors can quietly shrink your net raise: To plan realistically before October, you can:.
- Rising Medicare Part B premiums, which are often deducted directly from benefits, can offset part of the increase.
- General price growth may outpace the categories that matter most to older households, such as housing and medical care.
- Treat 3.6%–3.8% as a planning range, not a fixed figure.
- Wait for the official SSA announcement before adjusting a fixed budget.
- Check the SSA official COLA information page for the confirmed rate and effective date.
