About Listmargin
Free eBay fee and profit calculator that shows what you keep on a sale.
Listmargin works out your eBay final value fees, ad fees, and what you actually keep on a sale. Most fee calculators copy a four-line summary of eBay's rates. This one reads the full published schedule: all 46 category rates, the store subscription tables, and the four categories where crossing a price threshold re-rates the entire sale. It's free, with no signup and no paid tier. There's an embeddable version if you run a blog or a tool site. A weekly monitor re-reads eBay's own fee pages, so when a rate moves the calculator gets corrected instead of drifting out of date.
