How to get monthly average value using Dax?

[heejinyune]

Hi Community! 

I want to get average value in the past month. 

Anyone knows how to do this using Dax?

For example, I have a database like this:

Let's assume today date is 2022/11/09. So for the past month average value should be A124, A125, A126 models average duration. 

the answer will be 432 + 322 + 100 / 3 = 854 = 284.5 

Anyone know how to implement this average value during the past 1 month?

Thank you so much for your help! 

Thanks,

Jean

Hi @heejinyune ,

Please try:

Measure = CALCULATE(AVERAGE('Table'[Model Built Duration [Mins]]]),FILTER('Table',[Model Built Date]>=EDATE(TODAY(),-1)&&[Model Built Date]<=TODAY()))

Note: today is 2022/11/14, so the average is :(322+100)/2 = 211

Final output:

@heejinyune Try:

Measure =
  VAR __Date = MAX('Table'[Date])
  VAR __Year = YEAR(__Date)
  VAR __Month = MONTH(__Date)
  VAR __Table = FILTER(ALL('Table'),YEAR([Date]) = __Year && MONTH([Date]) = __Month)
  VAR __Return = AVERAGEX(__Table,[Model Built Duration [Mins])
RETURN
  __Return
