No cloud. No login. No server. One HTML file you open in any browser — on a plane, in a warehouse, anywhere. Calculate eBay fees and real profit with zero internet dependency.
Run a quick calculation right here — it works entirely inside this page, with no internet connection, no account, and nothing uploaded. Your numbers stay on your device. Enter a domestic ebay.com or ebay.de sale and watch fees, net profit, and margin update live, exactly like the full offline tool.
Domestic sales only. International destinations, promoted listings, listing upgrades, store/insertion fees, bulk CSV import/export, and auction vs. Buy-It-Now comparison are in the full tool.
