Assume that I have a Pivot Table that looks as follows:

Jan-08 Feb-08 Mar-08 Apr-08 Total
Client 1 10,000 11,000 8,000 14,000 43,000
Client 2 0 2,000 500 100 2,600
Client 3 5,000 4,500 0 0 9,500
Client 4 15,000 15,000 13,000 8,000 51,000
Client 5 3,500 5,000 7,500 9,000 25,000
33,500 37,500 29,000 31,100 131,100


I would like to have the Pivot table to produce results like this:

Jan-08 Feb-08 Mar-08 Apr-08 Total
Client 1 10,000 11,000 8,000 14,000 43,000
% of Prior
Month 110.00% 72.73% 175.00%
% of Current
Month 29.33% 27.59% 45.02%
Client 2 0 2,000 500 100 2,600
% of Prior
Month #DIV/0! 25.00% 20.00%
% of Current
Month 5.33% 1.72% 0.32%
Client 3 5,000 4,500 0 0 9,500
% of Prior
Month 90.00% 0.00% #DIV/0!
% of Current
Month 12.00% 0.00% 0.00%
Client 4 15,000 15,000 13,000 8,000 51,000
% of Prior
Month 100.00% 86.67% 61.54%
% of Current
Month 40.00% 44.83% 25.72%
Client 5 3,500 5,000 7,500 9,000 25,000
% of Prior
Month 142.86% 150.00% 120.00%
% of Current
Month 13.33% 25.86% 28.94%
33,500 37,500 29,000 31,100 131,100

For Client 2 for Feb-08 the % of Prior Month should be 100%. For Client 3
for Apr-08 the % of Prior Month should be 0%.

I don't know how to get the new rows to calculate inside the pivot table. I
think that Calculated Fields would be used but I can't seem to figure how to
do it after reading some books that I have.

Any help would be greatly appreciated.

This calculates % of prior month.
No Calculated Field or formula needed.
