Overview
See your real profit after seller fees across 8 resale marketplaces — and which one pays you the most.
Stop guessing what you'll actually make. FlipMargin shows your real profit after seller fees — instantly, right in your browser. COMPARE PLATFORMS SIDE BY SIDE Enter your sale price once and see the major resale marketplaces ranked by what actually lands in your pocket, with a "best" badge on the top result. The same item can pay noticeably more on one platform than another once fees come out — so you'll know where to list before you do. ACCURATE, UP-TO-DATE FEES Many fee calculators still rely on outdated rates. FlipMargin's numbers are checked against each marketplace's official fee policy, and the extension shows the date the rates were last verified so you can trust the result. YOUR TRUE PROFIT, NOT JUST FEES Add your item cost, shipping label cost, and any other expenses to see your real profit and profit margin, with a clear line-by-line breakdown of every fee taken out. PRIVATE BY DESIGN No account required. No tracking, no ads. The numbers you enter stay on your device and never leave your browser. The supported marketplaces are shown in the screenshots above. Whether you sell occasionally or full-time, FlipMargin helps you understand your margins and keep more of every sale.
