## DAX. How to create a three step Percent calculation

Hello,

I'm trying to replicate a calculation I normaly do in an Excel Pivot.

I can't do it in the raw data because any combination of the number will be off.

I'm new to PowerBi, so looking for any advice.

It's a basic calculation for measuring online advertising revenue called eCPM.

The calculation in Excel is (Revenue/Impressions)*1000 and then formatted to Average.

Below is the exact calculation by my labels in an excel pivot.

=('Estimated revenue (\$)' /'Ad impressions' )*1000

This has to be done in the Pivot, because the raw data set in Excel totals the eCPMs instead of averaging them, which inflates the number when doing multiple dates. For example, the \$11.52 would be \$16.13 if I didn't average the calculation on Excel Pivot.

I currently have the data uploaded from my Desktop in table into PowerBI Desktop.

## Re: DAX. How to create a three step Percent calculation

Could you please share a dummy sample? We need to write the DAX formula with data and its structure. The formula could be like this:

```eCPM =
AVERAGEX (
SUMMARIZE (
'table1',
'table1'[Device categories],
'table1'[Date],
"ecpm", 'table1'[Estimated revenue (\$)] / 'table1'[Ad impressions]
* 1000
),
[ecpm]
)```

Best Regards,

Dale

Sure, attached is a dummie example data set. Below is a screen showing the results I'm trying to replicate. The one in yellow (\$28.64) is the correct number, which is a pivot table calculated field. The one in orange (\$34.53) is calculated in Excel and then brought into the Pivot. You can see how they don't align when they are totalled. Both are set as Averages in the pivot.
