Early Look at 2026 Cost-Of-Living Adjustments and Maximum Contribution Base

by Calculated Risk on 8/12/2025 12:03:00 PM

The BLS reported earlier today:

The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) increased 2.5 percent over the last 12 months to an index level of 316.349 (1982-84=100). For the month, the index increased 0.1 percent prior to seasonal adjustment.

CPI-W is the index that is used to calculate the Cost-Of-Living Adjustments (COLA). The calculation dates have changed over time (see Cost-of-Living Adjustments), but the current calculation uses the average CPI-W for the three months in Q3 (July, August, September) and compares to the average for the highest previous average of Q3 months. Note: this is not the headline CPI-U and is not seasonally adjusted (NSA).

• In 2024, the Q3 average of CPI-W was 308.729.

The 2024 Q3 average was the highest Q3 average, so we only have to compare Q3 this year to last year.

This graph shows CPI-W since January 2000. The red lines are the Q3 average of CPI-W for each year.

Note: The year labeled is for the calculation, and the adjustment is effective for December of that year (received by beneficiaries in January of the following year).

CPI-W was up 2.5% year-over-year in July (down from 2.6% YoY in June), and although this is early – we need the data for July, August and September – my early guess is COLA will probably be close to 3% this year, up from 2.5% in 2025.
