- The last year in which a COLA became effective was 2008. Therefore the law requires that we use the average CPI-W for the third quarter of 2008 as the base from which we measure the increase (if any) in the average CPI-W. The base average is 215.495, as shown in the table below.
- Also shown in the table below, the average CPI-W for the third quarter of 2010 is 214.136. Because there is no increase in the CPI-W from the third quarter of 2008 through the third quarter of 2010, there is no COLA for December 2010.
|Third quarter total||646.486||642.409|
|Average (rounded to the nearest 0.001)||215.495||214.136|

With oil prices the past three months about half their peak value, CPI is slowly catching up but still below the 2008 calculation. The good news for seniors is they benefited from a higher SS payment than they would have received if the 2009 COLA was set a few months later after the price of oil crashed to $35 at the end of 2008.
