Royalties and Selling Fees

Find out what you actually keep from a sale. Enter a price and see the KDP royalty for an eBook or a printed book, or the fees Etsy and Gumroad take from a digital product, plus break-even prices and profit per order. The rates come from the platforms’ own pages and are dated on each tool, because fees change.
