Compare % difference 2 columns in a PT

[dji]

Hi
I have an Excel 2010 Pivot table .
I want to compare the % difference between customer sales in 2009 and 2008.
I have 3 columns at present Customer name ,Sales 2009 and Sales 2008. I would like a fourth column to show the % difference .Can someone assist me by outlining the process to do this. Much appreciated
