I have an issurance data where i have to check for persistency. I need help on how many people bought the policy throughout the 3 months period or how many people cancelled their policy after one momth. How can i formulate persistency on power bi?

@Anonymous , on the way, is I create a month year column and do count distinct month year for rolling three month data. So if If you get 3 it means they got for all three months.

Canceled in next month, check for next month based on cancellation date , You need to  join purchase and cancel both to same date table and the use userelationship and time intelligence 

example

Rolling 3 = CALCULATE(distinctcount(Table[Month Year]),DATESINPERIOD('Date'[Date],max('Date'[Date]),-3,MONTH))

Rolling 3 = CALCULATE(distinctcount(Table[Month Year]),DATESINPERIOD('Date'[Date],eomonth(max('Date'[Date]),0),-3,MONTH))

Purcahse in last three months /Customer id or policy id(if same policy)

Example of this month next month

MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD('Date'[Date]))
next MTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESMTD(dateadd('Date'[Date],1,MONTH)))

next month Sales = CALCULATE(SUM(Sales[Sales Amount]),nextmonth('Date'[Date]))
