Average of monthly percentage change

Hi,

 

I need the average of a monthly percentage change.

What I need to do is : SUM ([monthly %  change]) / DISTINCTCOUNT (calendar[year-month]) )

The issue I am facing is that I calculated the monthly percentage change with a measure. And I cannot SUM a measure.

 

I have following columns

shop_id   date   customers   
AAA   2020/11/1   5000   
AAA   2020/11/2   3000   
AAA   2020/12/1   4000   
AAA   2020/12/2   1000   

I calculated the following measures to get the monthly percentage change:

 

1. total = SUM(table[customers])

2. total_LM = CALCULATE([total], PREVIOUSMONTH(calendar[date]))

3.monthly % change = DIVIDE( [total], [total_LM]), BLANK())-1

 

shop_id   year-month   total   monthly % change  (measure) 
AAA   2020/ 11   8000   +20 %
AAA   2020/ 12   5000   -37.5 %    
AAA   2021/ 1   6000   +20 %   
AAA   2021/ 2   5000   -16.67 %    

 

I want to calculate SUM (monthly % change) / DISTINCTCOUNT (year-month) to get the average, so:

-14.17 / 4 = -3.54

 

Can anybody help me with this?

@nabe , Try like

averageX(values(Date[Month Year]),[monthly % change])

@amitchandak sorry , thanks for pointing this out. I edited the post.

I know how to calculate the monthly distinctcount,

 

but I don't know how to get the average of the monthly percentage change.

I thought I need to SUM all the monthly changes and divide by month.

@nabe , Try like

averageX(values(Date[Month Year]),[monthly % change])

@amitchandak 

sorry, I tried your proposed measure again and I think it works.

 

average= AVERAGEX(VALUES('calendar'[year/month]),[monthly % change])
 
Thank you very much for your help!

@amitchandak 

thanks, I tried the measure you were proposing, but it doesn't give me the correct result.

 

I created a test pbx. file. Kindly see the link below.
