I would like to know how to add a weighted average in my pivot table. In fact, I need to do the following calculation: SUM(col1 * col2)/SUM(col2)
.
I tried to do it by using the calculated field option but when I enter my formula, I just have the following result as an output: SUM((col1 * col2)/col2)
which is equal to SUM(col1)
.
You will need 1 calculated field, and 1 helper column
Helper Column
col3=col1*col2
Calculated field:
CF=Col3/Col1
If you try to do the helper column as a calculated field, it will sum col1
and col2
, then multiply them together which results in a meaningless answer
