Need help to calculate simple average as grand total

[Anonymous]

Hi,

I need help on calculating simple average as grand total. Like example below, I want grand total to be (17%+50%+67%+30%) divided by 4 projects = 41%. I do not want ($7 divided by $21 = 33%). How do I put this as a measure?

P/S 'Return (%)' = 'Revenue ($)' divided by 'Expense ($)'

Hi az38,

As Return% in itself is a measure, there is no such option to "Average" it when I right click.

@Anonymous Please try below measure

Measure = AVERAGEX('Table',DIVIDE('Table'[Revenue],'Table'[Expense],0))

Hello @Anonymous ,

I tried using your formula but it returns the below. I would like Simple Average % to appear as 7.355% [(7.71% +7.00%)/2]. Any idea?

Hi @Anonymous ,

I have uploaded the pbix with the sample dataset for your reference below.

The part that I need to figure out is on the measure for Simple Average %. The simple average % at project levels are correctly displayed in the visual table (they should be the same as return % at project level). However, the grand total for simple average % is incorrect. I would like to show it as sum of simple average % at project level when filters are applied in visual table; divided by count of projects when filters are applied in visual table. Example would be like snapshot below.

@Anonymous Please use below measure 

Simple Average = 
VAR _ratio = DIVIDE(SUM(data1[Revenue]),SUM(data1[Expenses]))
VAR _table = SUMMARIZE(data1,data1[Department Description],data1[Project],"total",DIVIDE(SUM(data1[Revenue]),SUM(data1[Expenses])))
RETURN IF(HASONEVALUE(data1[Project]),_ratio,AVERAGEX(_table,[total]))
