Cohort Analysis average

TheProv — Mon, 17 Jul 2023 14:26:02 GMT

Hi, I am analyzing a subscription service and I am trying to determine the average for the cohort analysis I have implemented.
I have a subscriptions table that looks as follows:

I determined the join month of a user in another table and generated the following measure:

Customers in cohort % = VAR CurrentMonthAfter = SELECTEDVALUE('Cohort Analisys'[Value]) VAR CurrentFirstOrderMonth = SELECTEDVALUE('Users'' Revenues & Active Months'[Join month]) VAR _EOMonth = EOMONTH(CurrentFirstOrderMonth, CurrentMonthAfter) Return DIVIDE( Calculate( DISTINCTCOUNT('subscriptions'[user_id]), Filter( 'subscriptions', 'subscriptions'[created_at] < _EOMonth && ('subscriptions'[ends_at] = BLANK() || 'subscriptions'[ends_at] > _EOMonth) && _EOMonth < TODAY() ) ), DISTINCTCOUNT('subscriptions'[user_id]) )

Now, the end result is something like this:

Now, instead of having the join month to build the rows, I'd love to have a single row with the average for the first, second, third month and so on.

Had trouble interpreting other's solution as I'm not a DAX pro.
Thanks in advance for anyone spending time on this!

Hi TheProv ,

To calculate the average for each month after the join month, you can create a new measure that calculates the average of the "Customers in cohort %" measure for each month. Here's a DAX measure that should help you achieve this:

Average Customers in Cohort % = VAR MaxMonthAfter = MAX('Cohort Analisys'[Value]) VAR Result = AVERAGEX( FILTER( ALL('Cohort Analisys'[Value]), 'Cohort Analisys'[Value] <= MaxMonthAfter ), CALCULATE( [Customers in cohort %], ALLEXCEPT('Users'' Revenues & Active Months', 'Users'' Revenues & Active Months'[Join month]) ) ) RETURN Result

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.
