Average for all customers

I'm needing some help crafting a DAX expression.

 

We have a customer service ticketing program, and I'm trying to compare the number of tickets generated for each customer over the last year, compared to the average over the last year for all customers. So my per customer calculation is:

CallCount LY = CALCULATE( [CallCount], DATESBETWEEN( Table1[Date], MAX(Calls[DateOpen])-365, MAX(Calls[DateOpen] ) ) )

 

But I'm having trouble generating the expression to find the average for all customers. Could you help me out with that one?
