## Divide sum of one column by the count of another

Hi,

I have a column LoS which is in number format with a sum total. The other column, ID, is a Count of text values.

Is it possible to divide LoS by ID?

Sure - you can do this as a DAX measurement.  Unless I'm misunderstanding your post, it should be simple as:

`Measure = LoS / ID`

And if you're worried about the possibility that 'ID' will be zero, you want to account for the divide-by-zero case with:

`Measure = DIVIDE(LoS, ID, 0)`

However, if you need the aggregations (sum of LoS, count of ID) done in the measurement:

`Measure = DIVIDE( SUM(LoS), COUNT(ID), 0 )`

And alternately, if the ID is text values, you can use COUNTROWS(ID) instead.

So make sure you click the "New Measure" button on the modelling tab.

or right click the table name and choose "New Measure" and add the above code by @malagari

`Measure = DIVIDE( SUM(LoS), COUNT(ID), 0 )`

Thanks alot. What I was doing wrong was I had the result to display in a KPI visual rather than a Card so I thought LoS / ID wasn't correct.

Thanks again.
