Approximately 70 million Americans receiving traditional Social Security, disability, and survivor benefits will learn their official 2027 cost-of-living adjustment (COLA) on Oct. 14 at 8:30 a.m. ET. The Social Security Administration plans to release the final adjustment figure immediately following the Bureau of Labor Statistics’ publication of the September Consumer Price Index (CPI) data. This annual adjustment relies on comparing the average Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) across July, August, and September against the matching third-quarter period from the previous year. Years marked by elevated consumer price pressures generally produce higher COLA updates as essential household expenses for food, fuel, and healthcare climb.
Advocacy organization The Senior Citizen League projects the 2027 COLA at 3.5%, marking the highest annual raise in four years. If September inflation statistics keep this baseline intact, a 3.5% adjustment would represent the largest COLA expansion since 2023. This projected 3.5% boost exceeds the 2.8% adjustment implemented in 2026 as well as the 2.5% increase granted in 2025. Under a 3.5% bump, the average monthly Social Security benefit would rise by $67.90, lifting typical payouts from $1,940.08 to $2,007.98. However, final calculations remain subject to change depending on the Bureau of Labor Statistics’ upcoming September inflation dataset.
Meanwhile, surging healthcare costs threaten to consume a significant portion of the incoming COLA increase for retirees. The latest Medicare Trustees Report projects that standard Medicare Part B monthly premiums will rise to $209.50 in 2027. This projected rate reflects a $6.60 monthly escalation over the current standard Part B premium of $202.90. Because Medicare Part B premiums are automatically withheld from monthly Social Security payments, higher premium costs directly diminish net benefit checks.
Beyond monthly premiums, annual out-of-pocket medical liabilities are also set to climb in 2027. The standard Medicare Part B annual deductible is projected to increase from $283 to approximately $292. Concurrently, costs connected to Medicare Part D prescription drug coverage are scheduled to expand. Standard Part D deductibles are expected to rise from $615 to $700, while maximum annual out-of-pocket thresholds will move from $2,100 to $2,400.
