Social Security recipients could see a 2027 cost-of-living adjustment between 3.6% and 3.8%, adding roughly $73 to $75 per month to the average retiree’s benefits as inflation cools, according to new projections from major seniors’ organizations and independent analysts.
The Senior Citizens League (TSCL), a nonpartisan advocacy group for older adults, projects the 2027 COLA will be 3.8%, unchanged from its forecast last month. If that estimate holds, the average monthly benefit would rise from $1,937.53 to $2,011.15—an increase of $73.62, according to TSCL’s July 14, 2026 announcement.
AARP, in its first-ever early COLA forecast, projects a slightly lower 3.6% adjustment. That would increase the average retired worker’s benefit by about $75 per month, based on current inflation trends and Federal Reserve projections for the remainder of the third quarter.
Independent Social Security and Medicare analyst Mary Johnson has lowered her 2027 COLA estimate to 3.7%, down from her 4.7% forecast issued last month. The revision reflects cooling inflation after the consumer price index fell 0.4% in June—the first monthly decline since May 2020—driven largely by falling gas prices.
The COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), a measure of price changes for food, energy, medical care, and other goods and services. The Social Security Administration bases the annual adjustment on how much the CPI-W changes in the third quarter (July, August, and September) compared to the same three months the previous year. The official 2027 COLA will be announced on October 14, 2026, after the Bureau of Labor Statistics releases September inflation data, and the increase will take effect with benefits paid in January 2027.
The 2027 projections represent a significant increase over the 2.8% COLA that took effect in January 2026, which added about $56 per month to the average retired worker’s benefit. Over the past 20 years, the average COLA has been 2.6%, according to TSCL.
However, uncertainty remains. Johnson cautioned that inflation trends could shift, particularly given ongoing tensions in the Middle East that could affect oil prices. “With renewed tensions with Iran in the Strait of Hormuz affecting oil prices, it is unclear whether this drop in inflation will be sustained,” she said. “Consumers looking for prices to go down may not feel that has happened yet.”
For many older Americans, the COLA carries outsized importance because Social Security is often their only source of inflation-protected income. Rich Johnson, vice president for financial security at the AARP Public Policy Institute, noted that reliable COLA information allows retirees to plan their budgets. “Family budgets have been under increasing pressure because of rising prices,” he said. “The sooner that we can give them reliable information as to how much their benefits might increase next year, the sooner they can start planning.”
Experts also highlighted that inflation has hit older Americans particularly hard in areas where they have little flexibility. Indivar Dutta-Gupta, a distinguished visiting fellow with the National Academy of Social Insurance, observed that “older Americans are feeling inflation most acutely in groceries, energy, housing and health care—areas where those on fixed incomes have little room to adjust to and absorb costs.”
