The projected 2027 Social Security Cost-of-Living Adjustment (COLA) is 3.6 percent based on recent Consumer Price Index data.

"Stubbornly hot inflation in August could push up the 2027 cost-of-living adjustment for Social Security recipients, according to a new estimate from AARP. The 2027 COLA is now projected at 3.6%, based on the August Consumer Price Index figures released on Wednesday, according to the advocacy group. AARP had forecast a 3.5% increase a month ago.Other groups are forecasting a slightly lower COLA, with the Senior Citizens League, an advocacy group for older Americans, projecting a 3.5% adjustment, down from its prior estimate of 3.6%.A benefit increase of 3.6% would represent the biggest annual adjustment in Social Security payments since 2023."

"Heading: Why It Matters Before Friday's August inflation report, the Senior Citizens League projected a 3.6 percent COLA for 2027, down from its earlier forecasts of 3.8 percent in June and July. The group said its August projection was based on July's 3.4 percent annual increase in the CPI-W."
