calculating churn

Hi mazwro ,

Thanks for the reply from MattAllington .

Please try:

Create a calculated column that considers a customer churned if they have not made a purchase within the past 12 months of the maximum date in the data set.

IsChurned =
var PY = CALCULATE(
MAX('Table'[order_YM]),
DATESINPERIOD(
'Table'[OrderDate],
MAX('Table'[OrderDate]),
-12,MONTH)
)
RETURN
IF(PY = BLANK(),"Churned", "Active")

Create a measure to calculate the number of churned customers:

Count =
CALCULATE(
COUNTROWS('Table'),
'Table'[IsChurned] = "Churned",
ALLEXCEPT('Table', 'Table'[order_YM])
)

If the problem is not solved successfully, I would be grateful if you could provide me with the pbix file or sample data.
