Know your real profit per sale on any marketplace. Enter your sale price, costs, and your platform's fees — and see your net profit, margin, and return on cost before you commit to a price.
Estimate only — enter your own platform's real fee rates; defaults are illustrative, not any specific marketplace's exact fees. Excludes ad spend, returns, and storage/FBA fees unless you include them above.
On any marketplace, three things stand between the sale price and what you keep: the platform's percentage fee, fixed per-order fees, and your own product and shipping costs. Miss any of them and a "profitable" price quietly loses money:
This calculator subtracts all of them to show the profit you actually pocket, your margin, and your return on the cash you tied up in the item.
Margin (profit ÷ price) tells you how much of each sale you keep. ROI (profit ÷ what you spent to stock and ship it) tells you how hard your money is working. Both matter: a high margin on a slow, cash-heavy item can be worse than a thinner margin that turns over fast.
Take your sale price, subtract the marketplace's percentage fee and any fixed per-order fees to get your payout, then subtract your product and shipping costs. What's left is profit. This calculator does it and also shows margin and ROI so you can price with confidence.
It varies by model, but many sellers aim for 20–40% net margin after all fees and costs. Below ~15% leaves little room for ads, returns, and mistakes. Use the calculator to check a price before you list it.
Yes — enter your platform's own fee percentage and fixed fees. For Etsy specifically, our Etsy fee calculator builds in Etsy's exact 2026 rates for you.
