Difference between two columns in a pivot table

[planner1234567]

Hi all,

Hoping someone can help me with an issue I'm having with pivot tables. I have an example below. I have a pivot table with two columns that are "Show values as...% of column total". I'd like to find the difference between those two columns without having to do a calculation outside of the pivot table. Is there anyway I can do this within the pivot table?

E.g in column F, the difference between d4 and e4 would be -1%.

Any idea??

Thank you in advance.

It looks like you are just needing to add a column "F" and put a formula in that column subtracting Column"E" from Column "D"....?
