Attrition Rate for last 12 months

Hi experts,

 

I'm trying to calculate the attrition rate for the last 12 month period.

 

So far I have the following table:

To calculate the YTD i used:

 

Overall Attrition Rate YTD =
TOTALYTD([Overall Attrition Rate], 'dimDate'[Date])
 
How can I filter that so it calculates for the last 12 months?
 
Best,
Soph

Nailed it!
 
Rolling 12M Overall Attrition Rate =
VAR __NrOfRollingMonths = 12
VAR __CurrentDate = MAX ( 'dimDate'[Date] )
VAR __RollingMonths =
    FILTER (
        ALL ( 'dimDate' ),
        'dimDate'[Date] > EDATE ( __CurrentDate, - __NrOfRollingMonths )
            && 'dimDate'[Date] <= __CurrentDate
    )
RETURN
    CALCULATE ( [Overall Attrition Rate], __RollingMonths )
