Social Security’s 2027 cost-of-living adjustment will use July–September 2026 inflation data, which may be outdated when it takes effect in January. The Motley Fool says the CPI-W measure, rising costs and deductions could leave retirees’ buying power unchanged or lower.
The Social Security Administration bases COLAs on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). The Senior Citizens League says that measure misses older Americans’ spending patterns and wants Congress to adopt a seniors-focused index such as CPI-E; it says CPI-E inflation has regularly run 0.2 percentage points above CPI-W.
Housing, health care, utilities, insurance and in-home assistance may rise faster than the COLA. The article says Medicare premiums rise each year and are deducted directly from Social Security checks; higher benefits may also make a greater share of Social Security taxable or lead to income-related monthly adjustment amount (IRMAA) surcharges. It suggests treating COLAs as partial income maintenance rather than a true raise.
