Hi @sjpbi ,

Please follow the steps below to try it out:

1.Create a date table

DateTable = CALENDAR(MIN(YourTable[Date]), MAX(YourTable[Date]))

2.Add columns year and month

Year = YEAR(DateTable[Date])
Month = FORMAT(DateTable[Date], "MMM")

3.Create a relationship between the Date column in your data table and the Date column in your date table.

4.Create a Measure for Monthly Average

MonthlyAverage = AVERAGEX(
    SUMMARIZE(
        YourTable,
        DateTable[Year],
        DateTable[Month],
        "MonthlySum", SUM(YourTable[Value])
    ),
    [MonthlySum]
)
