What is this tool?

Estimates your real net profit after marketplace fees (Amazon, Etsy, eBay, or Shopify), letting you enter your actual current fee rate since these fees are tiered and change over time.

How to use it

Choose your marketplace, enter your selling price, cost, and current fee percentage, and your net profit and margin after fees are calculated.

Check your marketplace's current published fee schedule for your specific product category before relying on the default starting percentage — fees frequently vary by category, not just by platform. Return rate here is a simplified estimate (it reduces expected profit proportionally) rather than an exact model of platform-specific return/restocking rules, which vary.
