Why profit can fall faster than the selling price
Product, packaging and shipping costs often stay the same when you lower a price. This comparison holds your entered costs and charged shipping fixed, then recalculates tax and eBay fees at the discounted item price.
Example: reducing a $100 item to $85 cuts the price by 15%. With 6% buyer tax, $40 product cost and $5 shipping cost, profit falls from $40.18 to $27.35. Volume, ad attribution and return rates are not predicted.
