Weighted Average by Customer and Product

Hi all, 

 

Sorry if this has been answered elsewhere, but looking for some hopefully easy help. I am new to Power BI having extensive knowledge in QlikSense. I know the logic around how this should be done (AGGR in QS) but am not finding the right/best way in DAX to handle.

 

Basically I would like to have the weighted average cost by customer and by product. A sample table and expected results are below. I'd like to pull this value in a whisker table with just one dot per customer and product - doing a straight average of Cost is misleading.

 

One small caveat - in the source data, there are different amount of rows per "cost per unit" per Customer as this is actually distribution customers, meaning Customer A might have 10 end-customers who buy through them at $1.00, 5 customers who buy through them at $0.80, etc. So we have to be careful about summing up Unit Cost and likely should use average/distinct instead.

 

I'm sure this is a mix of sumx, calculate, evaluate, etc but proving fruitless so far. Below is a table that I hope comes through ok.

 

Thank you for your help!

This is a measure but could also be a calculated column
