Why reseller fees destroy margins

Most new resellers eyeball a 30 % markup and call it profit — then wonder why their bank account isn't growing. Platform selling fees alone can swallow 8–15 % of your sale price before shipping, payment processing, taxes, and your cost of goods. This calculator surfaces every charge so you know your true net margin on every flip.
