Independent Social Security and Medicare analyst Mary Johnson predicts that U.S. Social Security recipients will receive a 3.4% cost-of-living adjustment (COLA) in 2027, which would be the largest increase in four years. Other forecasters, such as the Senior Citizens League and AARP, predict even higher increases, at 3.6% and 3.5% respectively. For a retiree receiving an average of $2,085 per month, a 3.4% adjustment would mean an increase of approximately $71 per month. The final COLA will be determined based on inflation data from August and September, with the Social Security Administration expected to announce the official figure in October.
