In Excel 2010 I wish to input a Pivot Table to create a value that is "% running total / estimate at that point of time". I can create a "running total", but I'm not able to divide it correctly with the "estimate at that point of time". The value much preferably be calculated within the Pivot Table and no changes to the input data format is allowed.
The example demonstrates better than words. The field I need help with creating in the Pivot Table is marked with ** ** ** ** ** ** ** **.
I've created a worksheet with the example: https://www.dropbox.com/s/4a2f66n6uxfikte/11649309%20Example%20pivot-table-running-total-percentage-of-an-absolute-value.xlsx
Thanks in advance.
Input Table
Input data is in the following format - no changes are allowed. For each month I have number of hours spent in that month and the estimate for the entire project at that point of time (not just for the month).
Month Hours spent Estimate
01-2012 1 50
02-2012 10 50
03-2012 5 60
04-2012 35 60
The Pivot Table I wish to create
** ** ** ** ** ** ** **
Month Hours spent Estimate % Hrs/Estimate
(running total) (How do I create this?)
01-2012 1 50 2%
02-2012 11 50 22%
03-2012 16 60 27%
04-2012 51 60 85%
