The 2027 Social Security COLA Is Announced October 14. Forecasters Expect the Biggest Raise in Four Years.
The Social Security Administration will announce the 2027 cost-of-living adjustment (COLA) on Wednesday, October 14, 2026, after the Bureau of Labor Statistics publishes September's inflation data. Forecasters expect an increase of between 3.4% and 3.6%, which would be the largest in about four years, up from 2.8% for 2026.
At AARP's projection of 3.6%, the average retired worker's monthly benefit would rise by about $75. The new amount takes effect with January 2027 payments.
Social Security beneficiaries will find out on Wednesday, October 14, 2026 how much their checks will rise next year. That is when the Social Security Administration is scheduled to announce the 2027 cost-of-living adjustment, shortly after the Bureau of Labor Statistics releases September's inflation figures.
Forecasters broadly agree on the range. AARP, publishing a COLA forecast for the first time, projects 3.6%. The Senior Citizens League expects 3.5%, down a tenth of a point from its previous estimate, and the Committee for a Responsible Federal Budget estimates 3.4%. Any of those would be a clear step up from the 2.8% increase beneficiaries received for 2026, and the largest adjustment in about four years.
What it means in dollars
Using its 3.6% projection, AARP estimates the average retired worker's benefit of about $2,086 a month would rise by roughly $75. The average surviving spouse, receiving about $1,933, would get around $70 more, and the average worker on Social Security Disability Insurance, receiving about $1,635, would get around $59 more. For comparison, the 2026 COLA raised the average retiree's benefit by about $56, from $2,015 to $2,071.
Why it can't be announced sooner
The adjustment is calculated by formula. It compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) in July, August, and September with the same months a year earlier. Two of those three months are already known; in August, the CPI-W was up 3.5% year over year. September's reading is the last piece, which is why forecasters are confident about the range but not the exact figure.
"Unless prices change dramatically in September, we're confident that the COLA will be in the mid-3 percent range," said Rich Johnson of the AARP Public Policy Institute. Tyler Bond of the National Academy of Social Insurance said the 2027 adjustment "will be particularly important" for older Americans.
What to watch
The increase will apply starting with January 2027 payments. Beneficiaries should also watch for the 2027 Medicare Part B premium, announced separately, since it is usually deducted directly from Social Security checks and can absorb part of any raise. We will update this story with the official COLA once it is announced on October 14.
Why It Matters
The COLA is the single annual adjustment that keeps Social Security benefits in line with prices, and for many of the tens of millions of Americans who receive them, it determines whether their income keeps pace with the cost of groceries, rent, and medicine. A raise in the mid-3% range would be a meaningful step up from this year's 2.8%, reflecting inflation that has run higher in 2026.
"Unless prices change dramatically in September, we're confident that the COLA will be in the mid-3 percent range," said Rich Johnson, vice president for financial security at the AARP Public Policy Institute.

Technical Analysis
The COLA formula is set by law. It compares the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for July, August, and September with the same three months a year earlier, and the percentage increase, rounded to the nearest tenth of a percent, becomes the next year's COLA. That is why the official figure can't be announced until September's inflation data is out.
Most of the data is already in. The Bureau of Labor Statistics reported on September 11 that the CPI-W rose 3.5% in August from a year earlier. Forecasters' estimates for September, including projections from the Federal Reserve Bank of Cleveland that AARP used, point to a final figure between 3.4% and 3.6%.
Historical Context
Automatic annual COLAs began in 1975. The largest was 14.3% in 1980, during a period of very high inflation. Between 2001 and 2025 the COLA averaged about 2.6%, and there was no increase at all in 2010, 2011, and 2016, when inflation was flat. More recently, a 1.3% COLA in 2021 left beneficiaries behind as prices surged, before 5.9% in 2022 and 8.7% in 2023 helped them catch up.
Risks
- The official figure depends on September CPI-W data, which could come in above or below forecasts.
- A larger COLA can be partly offset by higher Medicare Part B premiums, which are usually deducted directly from Social Security payments; the 2027 premium is announced separately.
- A COLA tracks average inflation for wage earners, so retirees whose costs rise faster, such as for healthcare or housing, may still lose ground.
Key Takeaways
- The SSA announces the 2027 COLA on Wednesday, October 14, 2026.
- Forecasts range from 3.4% to 3.6%, up from 2.8% in 2026 and the largest in about four years.
- At 3.6%, the average retiree would get about $75 more per month starting in January 2027.
- The COLA is based on the change in CPI-W for July to September compared with a year earlier.
- Higher Medicare Part B premiums could absorb part of the increase for many beneficiaries.
