Why the actual profit of my sold product is different from the initial profit?

Designers can set the profit rate when uploading artworks or in Product Management page, and the profit rate is a fixed number if you do not change it. But the actual sale prices will be affected by price fluctuation of blank product, usage of coupon code or bulk discount. The profit formula 
Actual Profits=Actual Sale Prices * Profit Rate
leads to the conclusion that, when sale price changes, your actual profit will change either.
