Online Selling Calculators
Selling online looks simple until fees, shipping, ads, and returns each take a slice of every order. These calculators show profit per unit and per month so a busy shop does not turn out to be a broke one.
Margin is the number to watch. A thin margin leaves no room for a bad month.
