Why sellers use fee calculators
Every marketplace and payment platform takes a cut, and the headline percentage rarely tells the whole story. A sale can carry a final value fee, a listing fee, a fixed per-order fee, payment processing, and optional promotion or ads costs, all before you subtract what the item cost you. These calculators pull those pieces together so you can see your true net proceeds and profit margin in seconds, and price with confidence.
Each tool is updated for 2026 US rates, works on any device, and lets you edit every rate so you can match your exact plan, category or account type. Nothing is stored and there's no sign-up.

Do the tools include processing fees?
Yes, where the platform charges processing it's built into the profit figure.
Are the 2026 rates exact?
They're typical US rates for planning and are editable in every calculator. Always confirm current rates in your seller dashboard.
