Social Security's annual cost-of-living adjustment took effect on California beneficiaries' checks in January 2026, and the announcement of what 2027's adjustment will be is roughly six weeks out. Whether those yearly adjustments keep pace with what it actually costs to live in this state is a legitimate question, and the answer involves a few moving parts that catch a lot of recipients off guard.

How COLA Gets Calculated
The Social Security Administration determines each year's adjustment by measuring the percentage change in the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, from the third quarter of one year to the third quarter of the next. The SSA announces the following year's adjustment each October after the Bureau of Labor Statistics finishes compiling that data, and it takes effect with January payments.
