2027 Social Security Cost-of-Living Adjustment Projected at 3.6%
9/8/2026, 11:52:50 PM
Forecast Overview
The nonpartisan advocacy group Senior Citizens League (TSCL) has revised its projection for the 2027 Social Security cost-of-living adjustment (COLA) to 3.6%. This figure is 0.8 percentage points higher than the 2.8% COLA applied in 2026 and would represent the largest annual increase since 2023.
Context and Methodology
Social Security COLAs are tied to the CPI-W, a Consumer Price Index subset that reflects the spending patterns of urban wage earners. Critics contend that CPI-W understates inflation experienced by retirees because it gives less weight to housing and medical expenses. They point to the CPI-E, which tracks spending by individuals aged 62 and older and has historically run about 0.7 percentage points above CPI-W over the past three years. If CPI-E inflation continues to match CPI-W through September, 2027 could be the first year since 2023 that Social Security benefits at least maintain purchasing power.
Projected Benefit Impact
Using the TSCL-based 3.6% increase, the average monthly benefit for retired workers would rise by roughly $75. TSCL’s illustrative figures show a pre-adjustment average of $2,086 and a post-adjustment average of $2,161. A separate analysis from 247WallSt cites an average benefit of $2,071 and a projected increase to about $2,146. Independent analyst Mary Johnson forecasts a 3.4% COLA, while AARP’s estimate is 3.5%.
Official Timeline
The Social Security Administration has scheduled the official announcement of the 2027 COLA for October 14, after the September CPI report is released. Until that date, the TSCL projection and other forecasts remain estimates.
Conflicting Reports & Gaps
The two benefit-impact calculations differ by roughly $15 in the baseline amount and $15 in the projected post-adjustment figure, reflecting variations in the underlying data sources. No source provides a definitive final COLA figure, and the impact on specific beneficiary groups (spouses, survivors, disabled workers) is not detailed beyond the average retiree estimate.
