## DAX: Weighted Average Prices From Two Tables

Hi all,

I'd like to calculate the Weighted Average Retail Price which was derived from the 'Sales' and 'Price' tables.  My data model is like:

• a 'Product' table and a 'Date' table which contains one to many relationship with the 'Sales' and 'Price' Tables
• Weighted Average Retail Price = Summation of ('Sales'[Total Unit Sold] * 'Price'[Retail Price]) / Sum('Sales'[Total Unit Sold])

 Product Table - ProductID

 Date Table - Date

 Sales Table - ProductID- Date- Unit Sold

 Price Table - ProductID- Price Scrapped Date- Retail Price

Can anyone help with this?  Thanks in advance.

You may refer to the measure below.

``````Measure =
DIVIDE (
SUMX ( 'Table', 'Table'[Qty Sold] * 'Table'[Retail Price] ),
SUM ( 'Table'[Qty Sold] )
)
``````

@Anonymous , try Like

``sumx(summarize('Product Table','Product Table'[ProductID],"_sum",sum('Sales'[Total Unit Sold]), "_avg",average('Price'[Retail Price])),divide(([_sum]*[_avg]),[_sum]))``

Thanks amitchandak, I tried the formula but it only returns an Average instead of Weighted Average :(...

Here's one example of Week 13.

• Weighted Average Retail Price = \$168.32 <-- this is the desired result for Week 13
• In Excel formula = SUMPRODUCT(Retail Price, Qty Sold) / SUM(Qty Sold)
• Average Retail Price = \$171.70

 WeekDate Retail Price Qty Sold 3/24/2019 \$162.99 0 3/25/2019 \$162.99 1 3/26/2019 \$162.99 2 3/27/2019 \$162.99 2 3/28/2019 \$159.99 0 3/29/2019 \$194.99 1 3/30/2019 \$194.99 0

Thanks again for the help.
