Social Security beneficiaries can expect a 3.8 percent cost-of-living adjustment in 2027, up from the 2.8 percent increase that took effect in January 2026, according to recent forecasts from the Social Security Administration and independent analysts.
The Social Security Administration calculates its annual COLA by comparing the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from the third quarter of one year to the same period in the following year. The 3.8 percent projection for 2027 reflects cooling inflation in recent months, with the estimate holding steady at 3.8% as inflation cools.

The Senior Citizens League and AARP, which regularly release COLA forecasts, both project the 3.8 percent figure based on the most recent inflation data. For a typical retiree receiving an average monthly benefit, this adjustment would translate to an increase of approximately $74 per month, according to estimates adding $74 monthly to benefits.
The 3.8 percent adjustment would rank as the third-largest COLA since 1977, following the record 8.7 percent increase in 2023, which came as inflation surged. The COLA has fluctuated significantly in recent years: 3.2 percent in 2024, 2.5 percent in 2025, and the current 2.8 percent for 2026. Over the past decade, the average COLA has been approximately 2.6 percent.

The official 2027 COLA will not be announced until October 2026, when the Social Security Administration releases the final figure based on third-quarter inflation data. Benefits with the new COLA will begin in January 2027. The estimate of 3.8 percent reflects the most current economic conditions, though inflation trends over the coming months could shift the final number slightly.
