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.

This graph shows CPI-W since January 2000. The red lines are the Q3 average of CPI-W for each year.
• In 2008, the Q3 average of CPI-W was 215.495. In the previous year, 2007, the average in Q3 of CPI-W was 203.596. That gave an increase of 5.8% for COLA for 2009.
• In 2009, the Q3 average of CPI-W was 211.013. That was a decline of 2.1% from 2008, however, by law, the adjustment is never negative so the benefits remained the same in 2010.
• In 2010, the Q3 average of CPI-W was 214.136. That was an increase of 1.5% from 2009, however the average was still below the Q3 average in 2008, so the adjustment was zero.
• CPI-W in July 2011 was 222.686. This is above the Q3 2008 average, although we still have to wait for the August and September CPI-W. CPI-W could be very volatile over the next couple of months, but if the current level holds, COLA would be around 3.3% for next year (the current 222.686 divided by the Q3 2008 level of 215.495).
This is still early - and gasoline prices are falling - but it appears that COLA will increase this year.
Contribution and Benefit Base
The law prohibits an increase in the contribution and benefit base if COLA is not greater than zero. However if the there is even a small increase in COLA, 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 2010 yet, but wages probably didn't increase much from 2009. If wages increased back to the 2008 level in 2010, and COLA is positive (seems likely right now), then the contribution base next year will be increased to around $109,000 to $110,000 from the current $106,800.
Remember - this is an early look and is only for one month in Q3. What matters is average CPI-W during Q3 (July, August and September).
NOTE on CPI-chained: There has been some discussion of switching from CPI-W to CPI-chained for COLA. This will not happen this year, but could impact future Cost-of-living adjustments, see: Cost of Living and CPI-Chained
