How to calculate monthly average

I have a Date column and I need to calculate the average value for each month by repeating that value for every day of that month.

Example,

DateValueAverage
1/1/2021 150100
1/2/2021 100100
1/20/2021 50100
2/5/2021 300200
2/10/2021 100200

Add the following column:

 

Avg = 
var __my = FORMAT(Table[Date],"mmyy") return
CALCULATE(
    AVERAGE(Table[Value]),
    FILTER(
        Table,
        format(Table[Date],"mmyy") = __my)
)
