Using Calculated Field to Express % Change in Pivot Table Columns

Hey Y'all,

I think this is relatively straight forward but I can't get my head around. I have a pivot table expressing values for three different months. What I'd like to have is a calculated column in the pivot table that compares one month to another and provides me a % difference.

I realize I could do this by hand, but I'd rather have the Pivot table formula work to make this happen quickly.

I've attached an example workbook for reference.

Thanks for your help.

Thank you. This solved my question.
