In return the book joins Kindle Unlimited and you earn per page read, plus access to Countdown Deals and free promotions. You cannot sell the eBook anywhere else during that period. Print editions are never affected. ## What KDP Select actually is KDP Select is an opt-in programme. Enrol a Kindle eBook and you agree that, for **90 days**, the digital edition will be sold nowhere but Amazon. Not Apple Books, not Kobo, not Google Play, not Barnes & Noble, and not from your own website. In exchange, the book enters **Kindle Unlimited**, Amazon's subscription library, and you start earning from pages read as well as copies sold. Two things people consistently misunderstand: - **It applies to the eBook only.** Your paperback and hardcover are completely unaffected. Sell them wherever you like. - **It renews automatically.** The 90-day term rolls over unless you turn auto-renewal off. Many authors discover they are still enrolled a year later. ## What you get KDP Select benefits Benefit What it means Kindle Unlimited Subscribers read your book at no extra cost to them; you are paid from a shared fund based on pages read. Higher royalty in some territories Select extends 70% eligibility to markets including Japan, India, Brazil and Mexico, where the standard rate would otherwise be 35%. Kindle Countdown Deals A timed discount with a visible countdown clock, while keeping your 70% royalty rate. Free Book Promotions Up to five days per 90-day term where the book is free: useful for pushing a series starter into readers' hands. The Kindle Unlimited access is the entire point. Everything else is a rounding error. ## What you give up Every other digital retailer on earth. Concretely: - Apple Books: small but meaningful, and disproportionately strong in some nonfiction categories. - Kobo: dominant in Canada, strong across Europe. - Google Play Books: large Android install base. - Barnes & Noble Nook: declining, but not zero. - Library distribution through OverDrive, Hoopla and similar. - Direct sales from your own website, where you would keep close to 100% of the price. **That last one is the one people forget.** If you have an email list, a podcast, or any owned audience, direct eBook sales are the highest-margin revenue in publishing. Select forecloses them entirely for 90 days. ## How Kindle Unlimited pays Kindle Unlimited does not pay you for a borrow. It pays you for **pages read**, measured in Amazon's own normalised page unit (KENP). Each month, Amazon puts a fixed sum into a global fund and divides it across every page read by every KU subscriber, across every book in the programme. Your share is your pages as a proportion of all pages. Which has three consequences that matter: - **The per-page rate floats.** It is not announced in advance and it is not guaranteed. It has historically sat somewhere near half a cent, but it moves, and it moves in response to how many other authors are competing for the same fund. - **Long books earn more per borrow.** A 500-page book read to the end pays roughly five times a 100-page one. - **Only pages actually read count.** A borrow that is abandoned at chapter two pays for chapter one and chapter two. This is a genuine, and uncomfortable, quality signal. ## The maths that decides it Strip away the arguments and the decision is arithmetic. Ask one question: **Would this book earn more from Kindle Unlimited page reads than from sales on every non-Amazon store combined?** Consider a 300-page novel priced at $4.99 on the 70% option, so roughly $3.43 per sale. #### The comparison One sale on Kobo / Apple / Google≈ $3.43 One full KU read-through (~450 KENP)≈ $2.00-$2.50 Select wins ifKU reads > ~1.5× lost sales So Select pays off when Kindle Unlimited generates _substantially more volume_ than the other stores would have. For a debut author with no audience anywhere, that is very likely, because "sales on other stores" is realistically zero, and KU at least offers discovery. For an established author with a following on Kobo and Apple, it is very likely not. The rates in this comparison assume the 70% eBook option. If you are unsure which royalty option you are on, or how the print equivalent works, see [Amazon KDP royalties explained](https://scholars.direct/Articles/how-to-self-publish-a-book-on-amazon/amazon-kdp-royalties-explained/). ## Who Select suits - **Genre fiction read at speed.** Romance, thriller, fantasy, science fiction, cosy mystery. KU subscribers in these categories read voraciously, several books a week, and they overwhelmingly borrow rather than buy. - **Series.** KU readers binge. A reader who borrows book one and reads to the end will very often borrow books two through six the same week. Page reads compound in a way single-title sales never do. - **Debut authors with no audience.** You are giving up sales you were not going to make. KU is a discovery engine, and discovery is the thing you lack. - **Long books.** More pages, more page reads, more revenue per borrow. ## Who should go wide - **Nonfiction.** Readers buy nonfiction and consult it; they rarely read it cover to cover, so page reads underperform badly. A business book bought at $9.99 pays roughly $6.99; the same book skimmed in KU might pay 40 cents. - **Literary fiction.** The audience skews toward buying, and toward the retailers Select locks you out of. - **Anyone with an owned audience.** Email list, newsletter, podcast, professional following. Direct sales at near-100% margin dwarf anything KU will pay you. - **Books aimed at libraries or institutions.** Select removes you from library distribution entirely. - **Authors with existing traction outside Amazon.** If Kobo already sells your work, exclusivity is simply throwing that revenue away. ## The strategy most authors miss Select is a per-title, per-term decision. It is not a philosophy, and you are not obliged to be consistent. Two approaches that work well: **Test it, then decide.** Enrol for one 90-day term. Turn off auto-renewal immediately so you do not forget. At the end, compare your KU page-read income against your realistic estimate of foregone sales elsewhere. Then choose with data instead of opinion. **Split your catalogue.** Put the fast-read genre series in Select. Keep the nonfiction and the flagship title wide. There is no rule requiring a single strategy across every book you own, and pretending there is costs authors money every year. ## How to leave Select You cannot exit mid-term. What you can do, and should do the moment you enrol, is switch **auto-renewal off** in your KDP Bookshelf. The book then leaves Select automatically when the current 90 days expire. Once out, allow a few days for other retailers to list the book, and remember that Kindle Unlimited readers lose access immediately. If you have a KU readership, tell them the book is leaving before it goes. ## Frequently asked questions Is KDP Select worth it? It depends on your genre. For fast-read genre fiction (romance, thriller, fantasy, cosy mystery) Kindle Unlimited readers borrow heavily and page reads can exceed what you would earn from sales on other stores. For nonfiction, literary fiction, and any book with an existing audience that buys rather than borrows, exclusivity usually costs more than it earns. Does KDP Select affect my paperback? No. KDP Select applies only to the Kindle eBook edition. You can sell paperbacks and hardcovers through any channel you like, including your own website and other retailers, while the eBook is enrolled. How long does KDP Select last? Ninety days per term. It renews automatically unless you turn auto-renewal off, which you can do at any point during the term. The book stays in Select until the current term expires. How much does Kindle Unlimited pay per page? There is no fixed rate. Amazon divides a monthly global fund among all pages read, so the per-page rate floats: historically it has hovered around half a cent, but it moves month to month and Amazon does not guarantee it. Can I sell my eBook on my own website while in KDP Select? No. Select requires the digital edition to be exclusive to Amazon for the full 90-day term, and that includes selling or giving away the eBook file from your own site. You can still sell print copies directly. Select is one decision on the pricing screen.
