With the release of the CPI report this morning, we now know the Cost of Living Adjustment (COLA), and the contribution base for 2015.

Currently CPI-W is the index that is used to calculate the Cost-Of-Living Adjustments (COLA). Here is a discussion from Social Security on the current calculation (1.7% increase) and a list of previous Cost-of-Living Adjustments. Note: this is not the headline CPI-U.

The contribution and benefit base will be $118,500 in 2015.

The National Average Wage Index increased to $44,888.16 in 2013, up 1.28% from $44,321.67 in 2012 (used to calculated contribution base).  A very small increase ...

SPECIAL 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 happen in the future, and the switch would impact future Cost-of-living adjustments, see: Cost of Living and CPI-Chained.

If CPI-chained was used instead of CPI-W, the COLA increase would be 1.6% instead of 1.7%. CPI-chained would have minimal impact on any one year, but would reduce benefits over time.
