Aggregate Month End Percentages

[Anonymous]

Say I have the following table:

Measure A        Measure B      Month

5                           10                 Jan

3                           30                 Jan

6                           10                 Feb

3                            5                  Feb

40                          50                Mar

What I need to do through DAX is this -

Get (A/B)% for each month: So Jan is (8/40)*100%, Feb is (9/15)*100% and Mar is 40/50*100%

Once I get Jan as 20%, Feb as 60% and March as 80% I need to average these three values --> (20+60+80)/3 = 53.33

How can I do this in dax ?

Hi,

I assume measure A and measure B are columns.

Please check the below picture and the attached pbix file.

Expected result measure: =
VAR _newtable =
    ADDCOLUMNS (
        VALUES ( Data[Month] ),
        "@sumcolumnA", CALCULATE ( SUM ( Data[Measure A] ) ),
        "@sumcolumnB", CALCULATE ( SUM ( Data[Measure B] ) )
    )
RETURN
    AVERAGEX ( _newtable, [@sumcolumnA] / [@sumcolumnB] ) * 100
