I suspect this will be an ongoing project, comparing the royalties offered by various ebook publishers/distributors.Amazon.com (Kindle): 35% (prices below 2.99) or 70% (2.99-9.99). Subtract at least a penny for delivery fees, and probably around 10 cents.[Have heard from MCA Hogarth that Kindle pays promptly and apparently accurately. They do not, however, yet have a master-page for a book where "all copies sold to date" reside, and all their data is by-book, rather than for all books by the author.]NOTE! Purchases which are not from one of Amazon's dozen or so "approved" countries will use theroyalty, even if you picked 70%!Barnes & Noble (PubIt!): 40% (prices below 2.99) or 65% (2.99-9.99).Bookbrewer: Charges minimum $39.99, sends to ebook stores (iBooks, etc.),takes a 25% cut of what you get from them (40%-45%, depending). You get no ePub file for your own. "Advanced" package doessubmit to ebookstores, but does give you the ePub file.Amazon.com via Bookbrewer: 40%-45% (2.99-9.99)Apple iBooks via Bookbrewer: 40%-45% (2.99-9.99)Barnes & Noble via Bookbrewer: 40%-45% (2.99-9.99)Borders via Bookbrewer: 40%-45% (2.99-9.99)Google Editions via Bookbrewer: 40%-45% (2.99-9.99)Kobo via Bookbrewer: 40%-45% (2.99-9.99)DriveThruFiction.com: "Exclusive publishers receive a 70% royalty on all digital sales and 70% royalty on the margin (sales price - print cost) on all print sales. They also receive more free promotion on the marketplace.Non-exclusive publishers receive a 65% royalty rate."eBookMall.com: 50%. Minimum price $2.98. Has $19.95 listing fee.eBooks.com: only deals with publishers.Fictionwise: "40%, with some subvendor caveats"[Bujold, on the Bujold mailing list. F'wise only takes previously-published authors and wants/wantedebook rights. Fictionwise is also stated to pay on-time and quarterly.]Google: Varies, though "the majority" goes to the publisher (or presumably self-publisher) when selling a book. They also show "relevant ads" alongside the sample pages, and "a majority" of any click-through revenue is "shared" with the publisher/self-publisher. It is a little unclear if Googleoffers to sell the book itself, or if it only links to an author's own buy-this-book web page and/or a third party distributor (such as B&N or Amazon). Generating false click-throughs on the ads, or giving people incentives to visit the page and click the links, can result in Google ditching the book.Kobobooks: "a competitive vendor commission based upon your suggested retail price"Lulu.com: 80%? (hard to figure out without actually publishing a book); may have a 99c fee."Your commission from retail sales is 80% after the retailer takes their share (30%).
