Monthly product performance since launch date

Sorry i am going to try to elaborate better 

I have Two table in my model, calendar date and sales

I am trying to create a table that will show all the product and then the sales the first month, second etc.. but then for all of the product on a normalised way ( For the month)  as in the table below

the goal is to be able to quickly see which product  had the best launch, is doing better, comparing product that have similarities

I hope this can help to understand why i am trying to do 🙂 

Thank  you in advance
