KDP Select vs going wide for a nonfiction ebook
KDP Select trades your ebook's freedom for Amazon's subscription money and promotion tools. Going wide means selling the ebook in every store that will take it. For a nonfiction author whose book exists to win clients or speaking work, the right answer often has less to do with royalties than with what you need to be allowed to do with the ebook.
What KDP Select is
Most self-published Kindle ebooks go through Kindle Direct Publishing, Amazon's own platform. KDP Select is an optional layer on top. Amazon calls it "a free 90-day program for Kindle eBooks and audiobooks open to all authors regardless of where you live" (KDP Select). Enrolling does three things:
- Subscription. The ebook is added automatically to Amazon's all-you-can-read subscription, and you earn a share of a monthly fund based on pages read.
- Promotions. The ebook becomes eligible for Free Book Promotions and Kindle Countdown Deals.
- Higher royalty in four countries. Enrolled ebooks can earn the 70% royalty on sales to customers in Brazil, Japan, Mexico and India. Outside Select, sales there earn 35% (KDP Terms and Conditions, KDP Select section 2.4).
A note on names. KDP's help pages now call the subscription Kindle+: "When you enroll your eBook or audiobook in KDP Select, it's automatically included in Kindle+." KDP's own Select landing page and the banners on those same help pages still say Kindle Unlimited. Both describe the subscription that enrolled books join, and the payment rules below come from the page titled Royalties in Kindle+.
The exclusivity terms, in Amazon's words
This is the part to read twice. The KDP Select terms say that while the book is enrolled, "you cannot sell or distribute, or give anyone else the right to sell or distribute, your Digital Book (or a book that is substantially similar), in digital format in any territory where you have rights" (KDP Terms). The enrollment page adds that during the 90 days the ebook "can only be distributed through KDP and public libraries," and that you "can continue to distribute print, video, or other formats of your title elsewhere" (KDP Select enrollment).
What that means in practice:
- The ebook cannot also be on Apple Books, Kobo, Google Play, Barnes & Noble or your own website, including as a free download.
- Paperbacks, hardcovers and other non-digital formats are unaffected.
- It renews itself. "Every Kindle eBook and audiobook enrolled in KDP Select is automatically renewed unless you turn off automatic renewal."
- Leaving early is limited. You have "three days from the start of your enrollment period" to cancel; after that the book stays in for the rest of the 90 days (KDP).
How page reads are paid
Subscription reads are not paid per borrow or per copy. They are paid per page, from a pooled fund:
- Your share. Earnings are "determined based on your share of total pages read or listened to by Kindle+ subscribers" (Royalties in Kindle+).
- The rate moves. "The KENP Rate is the total fund amount for a given marketplace divided by the total KENP read in that marketplace for that month." The fund for a month is announced around the 15th of the next one (KENP). KDP publishes no fixed per-page rate.
- Pages are standardized. KENP, the Kindle Edition Normalized Page, counts pages using standard formatting from the start of the book, usually chapter 1, and includes images and charts. A title can earn up to 3,000 KENP per customer.
- First reads only. "You're paid for the first time a subscriber reads or listens to a given page in your book." Rereading earns nothing extra.
For scale, KDP's pages show "Total KDP Select Author Earnings" of $69.3 million for September 2026. That is all enrolled authors combined, and says nothing about what one book will earn.
The per-page model matters for nonfiction. A reader who borrows your book, reads the two chapters they need and stops earns you those pages and no more. A buyer who pays for the ebook earns you the full royalty whether they read it or not.
The two promotions
Each 90-day period lets you run one of two promotions, not both: "You can run either a Free Book Promotion or a Kindle Countdown Deal (KCD) during the 90-day KDP Select enrollment period" (KDP).
| Free Book Promotion | Kindle Countdown Deal | |
|---|---|---|
| What it does | Ebook is free | Ebook is discounted for a limited time |
| How long | Up to 5 days per 90-day period, together or split; unused days do not roll over | Maximum 7 days |
| Where | All KDP marketplaces | Amazon.com and Amazon.co.uk only |
| Royalties | None on free copies | Your selected royalty rate on each sale |
| Conditions | Book enrolled and on sale; schedule at least a day ahead | Enrolled at least 30 days; price $2.99 to $24.99 on Amazon.com and unchanged 30 days before and 14 days after |

A free promotion can put an ebook in many hands at once. Note what it does not give you: nothing on KDP's promotion pages offers you the names or email addresses of the people who download it.
What going wide looks like
Wide means the ebook stays on KDP, without Select, and also goes to other stores, either directly or through an aggregator. Each store's own terms:
| Store or service | Ebook royalty, per its own pages | Subscription or library income |
|---|---|---|
| Apple Books | "70% royalties on all your titles regardless of price point"; "No hidden fees or exclusivity requirements"; paid within 45 days after month end | None stated |
| Kobo Writing Life | 70% of list at $2.99 and up (US); 45% below that | Kobo Plus, opt-in, "no exclusivity required"; paid per minute read; library sales via OverDrive at 50% of your library price |
| Google Play Books | 70% of list price in most supported countries once you accept updated terms; your existing split in 11 listed Asian markets; 52% default if you have not accepted | None stated |
| Barnes & Noble Press | 70% on ebooks; needs an ISBN never used elsewhere | None stated |
| Draft2Digital | The store's royalty, less about 10% of retail price | Sends to library systems including OverDrive, cloudLibrary, Hoopla and BorrowBox, and to Kobo Plus |

Two details worth knowing. Kobo pays Kobo Plus by time, not pages: it divides the month's subscription revenue by total minutes read, and says "the payment rate for authors on KWL is 60%" of that value. And Draft2Digital lists Amazon ebook distribution as "invite only," so most wide authors keep KDP for Amazon and use an aggregator or direct accounts for everything else. How the three main platforms compare on cost and reach is in KDP vs IngramSpark vs Draft2Digital, and Barnes & Noble's ISBN rules are in publishing with Barnes & Noble Press.
Going wide costs you something too: more accounts or an aggregator's share, no Amazon subscription income, and none of Select's promotions.
How to decide for a nonfiction book
Start with what the ebook is for. For many nonfiction authors the book is a way to win clients, talks or a reputation, not a royalty stream, and the right ebook setup follows from that.
| If the main goal is | Lean toward | Why |
|---|---|---|
| Ebook royalties, with readers mostly on Amazon | KDP Select | Subscription page reads plus promotions. Test one 90-day period. |
| Leads: an email list, clients, consulting | Wide, or KDP without Select | Select bars giving the ebook, or a substantially similar book, away in digital form, such as a download in exchange for an email address. |
| Speaking and credibility | Either; it matters less | What counts is that the book exists and reads well; which stores carry the ebook is a minor choice. Print is unaffected by Select. |
| Readers outside the US, or in libraries | Wide | Apple, Kobo, Google Play and library systems reach readers Amazon does not. |
| Bulk orders from a company or association | Either | Bulk orders are usually print. If a buyer wants digital copies, Select would block a direct deal. |
The lead question is where nonfiction authors most often trip. A common plan is to offer the ebook free on your own site in exchange for an email address, so you know who your readers are. Under Select that is the kind of digital distribution the terms rule out. If you want to offer a shorter guide built from the book instead, read the "substantially similar" wording above before you do, and ask KDP if you are unsure.
The book can matter a great deal to a business. For one Scribe author, Melissa Gonzalez, her story on scribemedia.com reports "3x: incoming leads tripled the year after the book." That is one author's result, not a typical one. For how authors use a book to win clients and bulk sales, see how to publish a business book.
There is also a middle path: enroll for one 90-day period around launch to use a promotion, turn off automatic renewal, and go wide when the period ends. Mark the end date; the book stays exclusive until then.
What most people get wrong
- Forgetting it renews. Enrollment rolls over every 90 days unless you switch automatic renewal off.
- Leaving the ebook up elsewhere. Listing it on another store, or as a free PDF on your site, while enrolled breaks the terms.
- Counting on a page rate. There is none. It is set each month from the fund and total reading.
- Thinking free downloads are leads. A free promotion moves copies, but it does not tell you who downloaded them.
- Assuming Select affects print. It does not. Paperbacks and hardcovers can be sold everywhere either way.

Common questions
What is the difference between KDP and KDP Select?
KDP is Amazon's own publishing platform, which most self-published Kindle ebooks use. KDP Select is an optional, free 90-day program inside KDP. In return for making the ebook exclusive to Amazon in digital form, it adds the book to Amazon's reading subscription (called Kindle+ on KDP's help pages and Kindle Unlimited on others), pays you for pages read there, and unlocks Free Book Promotions and Kindle Countdown Deals.
How much does KDP Select cost?
Nothing. KDP describes it as a free 90-day program. The cost is exclusivity: while the ebook is enrolled you cannot sell or distribute it, or a substantially similar book, in digital format anywhere else. Print editions can still be sold everywhere.
How much does Kindle Unlimited pay authors per page?
There is no fixed rate. KDP says the per-page rate is the month's fund for a marketplace divided by all the pages read there that month, so it changes monthly. You are paid only the first time a subscriber reads a given page, and the fund size is announced around the 15th of the following month.
How do KDP Select free promotion days work?
You can make the ebook free for up to five days in each 90-day enrollment period, all at once or split up. You earn no royalties on free copies, unused days do not roll over, and you can run either a free promotion or a Kindle Countdown Deal in a period, not both.
Is KDP Select worth it for authors?
It depends on what the ebook is for. If most readers buy on Amazon and you want subscription income and promotions, it can be. If you want the ebook in Apple Books, Kobo, Google Play and libraries, or want to give digital copies away to build an email list, exclusivity works against you. You can try one 90-day period and turn off automatic renewal.
