How about this DAX formula

var nbrMonths = YEARFRAC(startDate, endDate) * 12
var result    = DIVIDE(something, nbrMonths, 0)

    I was having an issue where I was using the DateDiff function in DAX and it was producing a rounded down number of months 

     

    Ie, if a transacted occurred on the 1st of Jan, 2023 and today is the 7th of July, 2023 the result returned for a DATEDIFF between the values was 6 months even though, technically, its 6 and a bit months. 

     

    For my logic, 6 and a bit months needed to be rounded up to 7 months

     

    I tried rounding functions on the DATEDIFF function but the realized it wouldn't work as a DATEDIFF doesn't produce a decimal

     

    Using your function produced the decimal and allowed the round function to work 

     

    This is my end expression for reference:

    Months Since Last Transacted = 
VAR LastTransacted = 
IF(
    ISBLANK(PTStock_Data[LAST_DEM_DATE]) && 
	ISBLANK(PTStock_Data[Last_Invoiced_Datetime]), 
    PTStock_Data[CREATION_DATE],
    IF(
        ISBLANK(PTStock_Data[LAST_DEM_DATE]) && 
		NOT(ISBLANK(PTStock_Data[Last_Invoiced_Datetime])),
        PTStock_Data[Last_Invoiced_Datetime], 
        PTStock_Data[LAST_DEM_DATE]
    )    
)
VAR MonthsSinceTransacted = 
ROUNDUP( YEARFRAC( LastTransacted, TODAY() ) *12, 0 )

RETURN
MonthsSinceTransacted
