Social Security 2027 COLA set to be announced October 14

The Social Security Administration will announce the 2027 cost-of-living adjustment on October 14, 2026, following the release of September inflation data from the Bureau of Labor Statistics. The announcement will reveal the percentage increase Social Security beneficiaries will receive starting in January 2027.

Current estimates suggest the 2027 COLA will range from 3.6% to 3.8%, a significant increase from the 2.8% adjustment announced for 2026. Recent forecasts from the Senior Citizens League project the increase at 3.6%, while other analyses estimate 3.8%, which would boost the average benefit by approximately $74 per month.

How COLA Is Determined

The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly known as the CPI-W. The Social Security Administration compares the average CPI-W for July, August, and September of the prior year with the same three-month average from the current year to determine the percentage increase.

Since 1983, this third-quarter inflation measure has been the standard for calculating annual adjustments to Social Security benefits. The October 14 announcement date is set because it coincides with the Bureau of Labor Statistics’ release of September CPI-W data, the final piece needed to complete the third-quarter calculation.

The 2027 COLA will represent a meaningful boost for the roughly 71 million Social Security beneficiaries in the United States, though the exact amount remains uncertain until the final inflation figures are released in mid-October. Beneficiaries can expect notification of the specific adjustment amount and its impact on their monthly payments shortly after the official announcement.
