The Social Security Administration will announce the 2027 cost-of-living adjustment on October 14, 2026, revealing how much benefits will increase for nearly 71 million beneficiaries next year. The COLA announcement comes as current estimates project a 3.6% increase, marking a significant jump from the 2.8% adjustment beneficiaries received for 2026.
The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as the CPI-W, a measure tracked by the U.S. Bureau of Labor Statistics. The Social Security Administration compares the average CPI-W from July, August, and September of the prior year with the same three months of the current year to determine the percentage increase.
According to projections from The Senior Citizens League and other analysts, a 3.6% adjustment would increase the average retired worker’s monthly benefit by approximately $75, raising it from about $2,086 to roughly $2,161 at the start of 2027. This would represent the largest boost since 2023, when beneficiaries received an 8.7% increase tied to the peak inflation period.
The timing of the October announcement follows the pattern established for COLA releases. Last year, the Social Security Administration announced the 2026 COLA of 2.8% on October 24, 2025, which took effect in January 2026. The annual October announcement allows the agency to finalize benefit amounts before the new rates begin in January.
Analysts have noted that while a 3.6% COLA provides meaningful relief, it still lags behind actual inflation experienced by seniors. In 2026, the 2.8% increase fell short of the 3.4% annual inflation rate, meaning beneficiaries’ purchasing power declined despite the adjustment. This gap between COLA and overall inflation remains a concern for retirees managing fixed incomes.

The 2027 COLA announcement also comes amid broader Social Security 2027 changes including higher earnings limits and credit updates, which will take effect the same year. Additionally, the retirement age reaches 67 for those born in 1960 or later in 2027, reflecting long-term adjustments to the program’s structure.
