CPI and COLAs



The BLS reported this morning: "The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) increased 4.1 percent over the last 12 months to an index level of 222.686 (1982-84=100)."CPI-W is the index that is used to calculate the Cost-Of-Living Adjustments (COLA). Here is an explanation ...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 not seasonally adjusted.
