Seller Profit Calculator

Most margin calculators stop at sale price minus cost. Seller Profit Calculator goes further. It helps online sellers calculate real profit after the costs that actually affect every sale: marketplace fees, delivery charges, sales tax, product cost and margin. Use it before you list, re-list, accept an offer, or reprice an item so you know what you are likely to keep. Designed for independent sellers, resellers, makers and small product businesses, our app helps you model selling prices quickly without having to remember formulas or rebuild the same calculation every time. KEY FEATURES • Calculate real profit after selling fees • Include delivery charges, sales tax and product cost • Model marketplace and platform fees • Save inventory items for faster repricing • Remodel prices without re-entering everything • Compare different selling scenarios • Calculate margin, markup and net profit • Useful for eBay, Amazon, Etsy, Shopify and other selling platforms • Built for quick pricing decisions on iPhone WHY IT IS DIFFERENT Free margin calculators are fine for simple sums. But selling online is rarely that simple. A profitable-looking item can become unprofitable once selling fees, delivery, tax and other costs are included. Seller Profit Calculator helps you see the real number before you commit to a price. SAVE INVENTORY. REPRICE FASTER. If you sell the same item more than once, you should not have to type the same product cost, delivery assumptions and fee details every time. Save inventory items in the app and remodel prices when costs, fees or selling platforms change. BUILT FOR SELLERS Use it when sourcing stock, preparing listings, checking marketplace fees, testing price changes or deciding whether an item is worth selling on a particular platform. Whether you sell through eBay, Amazon, Etsy, Shopify or another platform, Seller Profit Calculator helps you price with more confidence. IMPORTANT: Not affiliated with eBay, Amazon, Etsy or Shopify. Platform names are used only to describe configurable fee modelling in our app.
