Price Benchmarking - Weighted Average

I am looking for some assistance to create a measure that results in a weighted average price for products that share a common variable - in this case, products that share a common age.

 

The weighted average should take into account not only the prices of all products with the same age, but also the ‘brand rankings’.

  • 70% bias towards rank 1 prices
  • 15% rank 2 prices
  • 15% rank 3 prices

To illustrate what I am seeking, please see the example below:

As you can see, not all product ages have price examples from each of the brand ranks - the measure would need to be able to handle this.

 

I am unsure if this is something to tackle within the Excel file, or if we can achieve it in PowerBI. To assist, please see the following links for the Excel file and my attempts at a Power BI model.

Can anyone help please? Thanks in advance.

    Hi, this measure should do it. Just add it to your table visualisation

     

    Weighted Avg =
VAR SelectedAge =
    SELECTEDVALUE ( 'All Price Points'[Age] )
RETURN
    CALCULATE (
        DIVIDE (
            SUMX (
                'All Price Points',
                SWITCH ( RELATED ( 'BRAND RANKINGS'[Brand Rank] ), 1, 0.7, 2, 0.15, 3, 0.15 ) * 'All Price Points'[Price]
            ),
            SUMX (
                'All Price Points',
                SWITCH ( RELATED ( 'BRAND RANKINGS'[Brand Rank] ), 1, 0.7, 2, 0.15, 3, 0.15 )
            )
        ),
        ALL ( 'All Price Points' ),
        'All Price Points'[Age] = SelectedAge
    )
