creating a monthly average column

[JaviGoldstein]

I am trying to create a monthly average column for an exchange rate table.   Here is a screenshot of the the table structure:

What would be the best way to calculate a monthly average rate per combo in the table?   Thx!

Hi @JaviGoldstein ,

Please try to create a new column with below dax formula:

Column =
VAR cur_combo = [Combo]
VAR cur_date = [Date]
VAR cur_year =
    YEAR ( cur_date )
VAR cur_month =
    MONTH ( cur_date )
VAR tmp =
    FILTER (
        'Table',
        [Combo] = cur_combo
            && YEAR ( [Date] ) = cur_year
            && MONTH ( [Date] ) = cur_month
    )
RETURN
    AVERAGEX ( tmp, [Rate] )

Please refer the attached .pbix file.
