# Calculated Field to divide amount by total and multiple by number

1. ## Calculated Field to divide amount by total and multiple by number

Hi,

I know I might need to put this formula outside of the pivot table after trying different ways but does anyone know of a way I can insert a calculated field to divide a number by the Grand Total and then multiple by a figure:
For example:

Name: Amount: Formula:
A £10 (=£10/£37)*£5 = £1.35
B £5 (=£5/£37) * £5 = £0.67
C £3 etc
D £8 etc
E £11 etc.......
Grand Total £37

Thanks

As you are using the 365 version of Excel you could use Power Pivot.
1. Convert A1:B6 into a table
2. Add the table to the Data Model and then add a column (Total) populated using: =sum(Table1[Amount])
4. Produce a pivot table from the data model put Category in the Rows area then Amount and Formula in the Values area.
Note that Formula is formatted through the Data Model.
