This free tool lets you calculate real profit per product on a marketplace before you create a listing. You'll see exactly how fees, shipping, and overheads affect your bottom line - so you don't list products that lose money.

Add your cost price, shipping costs, and any other overheads you want to account for.
Enter the price you plan to list at.
