How big could the 2027 COLA be? Early predictions give Social Security clues

Social Security recipients started 2026 with average monthly checks going above $2,000 for the first time, after a 2.8% cost-of-living adjustment (COLA). Even though 2026 has just begun, seniors and advocacy groups are already focused on how big the 2027 COLA might be.

Early prediction points to a smaller increase in 2027. The Senior Citizens League (TSCL), a bipartisan senior advocacy group, predicts the 2027 COLA could be around 2.5%, which would be lower than the 2026 increase.

How COLA is calculated

The Social Security Administration calculates COLA using changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) from July to September of the current year. The CPI-W data used for COLA calculations is produced by the Bureau of Labor Statistics, according to federal guidelines. Using the same formula, TSCL estimates a 2.5% COLA would add roughly $50 a month to the average Social Security check.


Cost-of-living adjustments are designed to help seniors keep up with rising prices, especially during periods of inflation. TSCL says COLA increases often lag behind actual costs for housing, health care, utilities, and other daily needs. TSCL notes that even with payments above $2,000, many retirees still struggle to cover basic expenses like rent, electricity, and medical bills.

A large number of Social Security recipients live on fixed incomes and rely almost entirely on their monthly benefits, according to senior advocacy groups. Because their income does not change, beneficiaries depend heavily on annual COLA increases to stay financially stable as prices rise, MassLive reported.

Medicare cuts into COLA

The 2.8% COLA in 2026 added about $56 per month on average, but much of that increase was offset by higher Medicare costs, according to MassLive. Medicare Part B premiums are usually deducted automatically, meaning many seniors never fully see their COLA increase.

Medicare Part B premiums rose by nearly 10% this year, marking one of the largest single-year dollar increases in the program’s history, according to CNN. Advocacy groups say early estimates help retirees prepare for future income changes, even though the final 2027 COLA will not be announced until later.
