Incorrect profit calculation in "Calculated price"

Under heading "Calculated price" the amount of profit excluding VAT is displayed which is incorrect. Your system calculates variable fee over VAT exclusive amount, but it should be taken over VAT inclusive amount. Suppose I sell a product for 169.99 euros, then variable fee is 15% over 169.99 costs. This is how I have always calculated my profit. Amazon itself also indicates it on their website:

"Selling partners pay a referral fee on each item sold. For all products, Amazon deducts the applicable referral fee percentage calculated on the total sales price. The total sales price is the total amount paid by the buyer, including the item price and any delivery or gift wrapping charges."
