Hi,

Create a Calendar Table with calculated column formulas for Year, Month name and Month number.  Sort the Month name by the Month number.  Create a relationship (Many to One and Single) from the Date column of your Data Table to the Date column of the Calendar Table.  Create a slicer of Year (from the Calendar Table) and select 2022.  Write these measures:

Total = sum(Data[Sale])

Average sales till end of previous month = averagex(summarize(calculatetable(calendar,datesbetween(calendar[date],min(calendar[date]),eomonth(today(),-1))),calendar[year],calendar[month name],"ABCD",[Total]),[abcd])

Hope this helps.

@dakins ,  Try a measure like

YTD Today =
var _min = eomonth(today(),-1*month(today()))+1
var _max = if(today() = eomonth( today(),0),eomonth( today(),0),eomonth(today(),-1))
return
CALCULATE(AverageX(values('Date'[Date]) ,[Net]), FILTER('Date','Date'[Date] >=_min && 'Date'[Date] <= _max))
