Pivot Calculated formula: SUM(Field1)/AVG(Field2)

Question

I\'ve a simple table with some amount and interval in sec by date and product name.

Month | Product | Amount | Interval in sec
------------------------------         


        

Answer 1

You need to refer to the pivot table data in your formula, something like this:

=GETPIVOTDATA("Sum of Amount",$A$3,"Product","A")/GETPIVOTDATA("Average of Interval",$A$3,"Product","A")

Edit: From your spreadsheet: To add your desired column to Pivot Table A:

K5=GETPIVOTDATA("Sum of Amount",$H$2,"Month",DATE(2012,5,1),"Product","Prod A")/GETPIVOTDATA("Average of Interval",$H$2,"Month",DATE(2012,5,1),"Product","Prod A")
K6=GETPIVOTDATA("Sum of Amount",$H$2,"Month",DATE(2012,5,1),"Product","Prod B")/GETPIVOTDATA("Average of Interval",$H$2,"Month",DATE(2012,5,1),"Product","Prod B")
K7=GETPIVOTDATA("Sum of Amount",$H$2,"Month",DATE(2012,5,1),"Product","Prod C")/GETPIVOTDATA("Average of Interval",$H$2,"Month",DATE(2012,5,1),"Product","Prod C")

You can also produce the column by adding an extra column to the original data table of: Amount/Sec for each individual entry then when you pivot all the data the product of that column will be your desired result.

Edit (2):

The formulas above are cell formulas not pivot table formulas which can't use references sorry I didn't make that clear. I am looking into a pivot table calculation formula but for now the above as a column alongside your pivot table should produce what you need.
