Early Look at 2019 Cost-Of-Living Adjustments and Maximum Contribution Base

The BLS reported this morning:

The Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) increased 3.2 percent over the last 12 months to an index level of 246.155 (1982-84=100). For the month, the index was unchanged 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 2017, the Q3 average of CPI-W was 239.668.

Last year was the highest Q3 average, so we 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 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 3.2% year-over-year in July, and although this is very early – we need the data for August and September – my current guess is COLA will probably be close to 3% this year, the largest annual increase since 2012.

Contribution and Benefit Base

The contribution base will be adjusted using the National Average Wage Index. This is based on a one year lag. The National Average Wage Index is not available for 2017 yet, but wages probably increased again in 2017. If wages increased the average of the last three years, then the contribution base next year will increase to around $132,000 in 2019, from the current $128,400.

Remember – this is an early look. What matters is average CPI-W for all three months in Q3 (July, August and September).
