Marketplace Fee Calculator

About this calculator

Online marketplaces like Etsy, eBay and many others typically charge sellers a combination of a percentage fee (a cut of the sale price) and a flat fixed fee per transaction or listing, and your net payout is the sale price minus both. Because the fixed fee doesn’t scale with price, it eats a much larger share of a cheap item’s revenue than an expensive one, which is why the effective fee rate (total fees ÷ sale price) varies by price point even on a marketplace with a single stated percentage.

Sellers use this math to price items so they still turn a profit after fees, and to compare which marketplace or listing tier actually nets more money for a given item — the platform with the lower headline percentage isn’t always the better deal once fixed fees are included. This calculator takes your sale price, percentage fee, and fixed fee, and returns your net payout, total fee, and effective fee rate.
