Ratio between two tables

[mj29109]

Hi

This is my first post and question, hope someone helps me to resolve my query.

I have two different tables, Table1 (Employee Separations) and Table2 (Headcount). I have imported both tables in Power BI desktop.

In excel I can simply divide the separations with headcount to find the Attrition rate, but here in power BI. I am unable to calculate these things. I want the following result mentioned in last highlighted column.

Hi @mj29109,

In case you had 2 tables (Headcount(Month,Headcount) & Separation(Month,Separation)):

• In Modeling, choose new table by expression:

Data = SUMMARIZE( NATURALINNERJOIN(Headcount,Separations),Headcount[Month],Headcount[Headcount],Separations[Separations])

• Create calculated column for attrition ( this could be achieved by calculated measure as well )

Attrition (%) = DIVIDE(Data[Separations],Data[Headcount])

If this works for you please accept it as solution and also like to give KUDOS.

Best regards

You can create a Measure:

Attrition = Sum(Separations[Separations])/SUM(HeadCount[HeadCount])

And use it in a table visual

Thank you Vvelarde it worked for me... 🙂 i was just missing a single bracket to close the first argument....

This is the simple example what i want to do... first i want to calculate the table 1(Separations) Names, then table2(headcount) Names. once i get the result like 5 separations and 5 headcounts. then i would like to make a ratio of 5 / 5 = 1.

i am unable to sum because i am counting a areas, so can i use divide measue with count/CountA?

Also I would like to add on top of what @Vvelarde mentioned that there is relationship between botht those tables on a common field.

There is only "month" is common in both tables. can i make a relationship with the help of months?
