Estimate your real marketplace profit after platform fees, payment processing, shipping, product cost, ads, and returns. Use the result to price products, compare fee pressure, and protect margin before listing.
Enter your product selling price, unit cost, combined marketplace and payment fee rate, and the total variable costs you expect for shipping, ads, and returns.
The calculator estimates net profit, margin, fee burden, break-even price, and a practical seller health score.
A higher net profit and margin means the listing can absorb marketplace fees without depending on volume alone. Low margin means pricing, shipping, or advertising needs adjustment before scaling.
This estimate is best used before listing a product or when comparing marketplaces with different fee structures.
If a product sells for $80, costs $35, has an 18% combined fee rate, and $14 of shipping, advertising, and return cost, estimated profit is $16.60 and margin is about 20.75%.
Subtract product cost, marketplace fees, payment fees, shipping, ads, and expected return cost from the selling price. The remaining amount is your estimated net profit per sale.
Marketplace fees reduce margin directly because they are usually charged as a percentage of the sale price. Higher fee rates require higher pricing or lower costs to maintain profit.
Start with product cost, shipping, ads, and target profit, then gross up for the marketplace and payment fee rate. This calculator gives a break-even reference.
The more profitable channel depends on referral fees, fulfillment costs, ads, shipping, and return rates. Compare net margin rather than only the platform fee percentage.
Improve bundle size, reduce returns, lower paid promotion waste, negotiate shipping costs, and choose the marketplace where your category fee and buyer intent are strongest.
