Marketplace Fee & Profit Calculator
Enter your product cost, selling price and pick your platform — see your exact profit after eBay, Etsy, Amazon FBA, Shopify or Stripe fees.
Adjust the inputs — results update instantly.
Marketplace fees eat into your profits more than most sellers realize. eBay charges 13.25% plus a fixed fee. Etsy stacks a transaction fee, payment processing fee, and listing fee. Amazon FBA adds fulfillment costs on top of referral fees. Without calculating these upfront, you can easily think you are making money while actually losing it.
This calculator gives you the exact profit, margin, and ROI for any product on any major platform — so you never get surprised after the sale.
How it works
Enter your product cost (what you paid for it), your selling price, and any shipping cost passed to the customer. Select your selling platform and country. The calculator applies the exact current fee structure for each platform and shows you your net profit, profit margin percentage, and ROI.
The break-even price shows the minimum you must charge to avoid losing money. The doughnut chart visualizes how your selling price is split between product cost, platform fees, and profit.
