More than 71 million Social Security beneficiaries are waiting on one number. On Wednesday, Oct. 14, the Bureau of Labor Statistics releases the September inflation report. That is the final piece needed to set the 2027 cost-of-living adjustment (COLA), the annual raise meant to keep benefits in step with rising prices.
Early projections suggest it will be a big one.
What the estimates say
After the August inflation data came out, two independent trackers, The Senior Citizens League and Social Security and Medicare policy analyst Mary Johnson, both set their 2027 COLA forecast at 3.5%. If that holds, it would be the sixth-largest raise since 1993. These are estimates. The Social Security Administration announces the official figure.
What a 3.5% raise means in dollars
Say your current benefit is $2,000 a month. A 3.5% COLA adds about $70 a month, or $840 a year. Your own increase depends on your benefit. A bigger raise isn’t automatically good news, though. It exists because prices rose, so much of it goes to costs you already face.
Why the raise is so large
Two forces are behind it, according to the source analysis:
1. Energy prices and trade policy. Disruption around the Strait of Hormuz has driven fuel costs sharply higher. Annual inflation reached a three-year high of 4.2% in May. Tariffs also played a part. The Supreme Court struck down the earlier round in February 2026, but those tariffs had already pushed prices up, and a new round of global tariffs began in July.
2. The AI infrastructure build-out. This one is new. In June, the Federal Reserve began describing the AI data center boom as inflationary. Strong demand and ongoing shortages of GPUs, memory and storage have raised hardware prices, and those increases reach consumers through laptops, phones and other devices. The source expects this pressure to continue.
What to watch on Oct. 14
- The September CPI-W reading. The COLA is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), so that is the figure to watch.
- The official COLA announcement. If it differs from 3.5%, the dollar amounts above change.
- Medicare Part B premiums. These are deducted from many checks and can take back part of the raise.
