How do you calculate the rolling average per week/month?

Hi mdbuzzer ,

1.Create three calculated columns.

weeknum = WEEKNUM([Date],2)

Average = CALCULATE(AVERAGE('Table'[Value]),ALLEXCEPT('Table','Table'[weeknum]))

week = WEEKDAY([Date],2)

2.Create a new table and create a relationship with main table.

Table 2 = FILTER('Table',[week]=3)

3.Create a calculated column in the new table.

Rolling average = CALCULATE(SUM('Table 2'[Average]),FILTER(ALL('Table 2'),[Date]<=EARLIER('Table 2'[Date])))

4.The result is as follows.

You can check more details from here.
