Calculating Total individual product sales?


Under Earnings, you can’t break down sales based on the product (which is strange).

The only way I can seem to see total sales is in my portfolio where it lists out the following:
Purchases: xxx (xxx p/month)
Item sales: $xxx ($xxx p/month)
Support sales: $xxx ($xxx p/month)

Does this take into account refunds, and fees? Or is this GROSS before refunds and fees? I am trying to find out how much after commissions and refunds a product has made in sales.

Thanks in advance.
