The annual COLA is designed to help Social Security recipients keep pace with rising consumer prices. While the official adjustment will not be announced until later this year, recent inflation trends have become a central factor in updated projections for 2027.
Social Security benefits are adjusted each year based on inflation measured through the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). According to the Social Security Administration, the adjustment is determined by comparing average CPI-W readings during the third quarter of one year with those from the same period a year earlier.
For 2026, beneficiaries received a 2.8% COLA because CPI-W inflation increased by 2.8% during the third quarter of 2025. The latest estimate from The Senior Citizens League (TSCL) places the 2027 COLA at 3.8%, which would be one percentage point higher than the current year’s adjustment.
Inflation Trends Are Driving Higher COLA Expectations
Recent inflation data has contributed to expectations that the 2027 COLA could exceed the latest TSCL forecast. According to reports, CPI-W inflation fell to 2.2% in January before accelerating in subsequent months. CPI-W inflation reached 3.3% in March, 3.9% in April, and 4.4% in May. These increases were linked to rising energy prices associated with conflict involving Iran and disruptions affecting oil supplies and transportation routes.
According to the International Energy Agency, the conflict has resulted in what was described as the largest oil supply disruption in history. Supply chain bottlenecks and damaged infrastructure may continue to affect prices through the summer months.
A forecasting model from the Federal Reserve Bank of Cleveland shows the broader Consumer Price Index increasing 6.7% during the second quarter. While the CPI is not identical to the CPI-W used for Social Security calculations.
The report states that if CPI-W inflation remained at May’s level of 4.4% through the third quarter, Social Security benefits would receive a 4.4% COLA. Independent Social Security and Medicare policy analyst Mary Johnson, formerly affiliated with TSCL, recently increased her forecast to 4.7%. According to Johnson, there is “a considerable likelihood” that the estimate could move higher as additional inflation data becomes available.
What Different COLA Scenarios Could Mean for Beneficiaries
The official 2027 COLA is expected to be announced after third-quarter inflation data becomes available. The Bureau of Labor Statistics is scheduled to publish its September inflation report on October 14, and the Social Security Administration is expected to announce the adjustment on the same day. Different COLA outcomes would affect average monthly benefits. For retired workers receiving an average benefit of $2,081 today, a 3.8% COLA would raise that amount to $2,160 per month. A 4.7% COLA would increase the average monthly benefit to $2,179.
Under the 3.8% scenario, the average retired worker would receive an additional $79 per month, or $948 over a full year. Under the 4.7% scenario cited in the report, the increase would be $98 per month, totaling $1,176 annually. Similar increases are shown for spouses, survivors, and disabled workers receiving Social Security benefits.
