Social Security’s cost-of-living adjustment for 2027 is projected at 3.6%, according to the Senior Citizens League, marking a slight decline from the 3.8% forecast issued a month earlier as inflation has cooled in recent weeks.
The adjustment would translate to roughly $75 more per month for the average retiree, raising the typical benefit from about $2,071 to approximately $2,146 starting in January 2027. Despite the downward revision, a 3.6% increase would still represent the largest annual Social Security COLA since 2023’s 8.7% bump.
Both the Senior Citizens League and AARP lowered their 2027 COLA forecasts following the July Consumer Price Index report released Wednesday, which showed inflation easing to 3.4% annually from 3.5% in June. The revised projections arrive as the Social Security Administration prepares to announce the official 2027 adjustment in October, after September’s inflation data becomes available.
Social Security’s COLA is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), specifically the average of that index for the third quarter—July, August, and September—compared to the same quarter the prior year. This methodology has drawn criticism from advocates who argue it doesn’t capture the actual inflation that seniors experience on essentials like healthcare, housing, and groceries.
The Senior Citizens League has long pushed for Congress to adopt the Consumer Price Index for the Elderly (CPI-E), which tracks spending patterns of Americans 62 and older. The organization notes that 89% of seniors surveyed in June said the 2026 COLA of 2.8% left their benefits short of the inflation they actually faced. Shannon Benton, the League’s executive director, stated in a press release that “inflation’s volatility” has complicated this year’s forecasts, though the organization’s model is designed to avoid “chasing every spike and dip.”
The 3.6% projection, if realized, would exceed the 2.8% adjustment that took effect in January 2026. Compared to prior years, a 3.6% COLA ranks well above recent adjustments: the 2025 COLA was 2.5%, the 2024 COLA was 3.2%, and the 2022 COLA was 5.9%. The 2023 adjustment of 8.7% remains the highest in recent memory, driven by the elevated inflation that followed the pandemic.
The formal announcement will come on October 14, 2026, after the Social Security Administration receives the final September inflation data. Until then, the forecast remains subject to change, as additional monthly CPI reports could shift the projection in either direction.
