Calculate margins, marketplace fees, shipping costs, and break-even points.
Margins, marketplace fees, shipping costs, and break-even points are the real numbers behind whether a product is actually profitable to sell -- and they're easy to get wrong by estimating instead of calculating, especially shipping, where box dimensions matter as much as weight. These tools exist to make those numbers concrete before pricing decisions are made, not after.
