KDP Select vs Going Wide: How to Decide

No decision divides indie authors more than this one. KDP Select offers Kindle Unlimited readers and Amazon's promotional tools, at the cost of exclusivity. Going wide offers many stores, libraries and direct sales, at the cost of building an audience across them. There is no universal right answer, but there is a right answer for your books.

What KDP Select actually is

According to Amazon, KDP Select is a free 90-day program for Kindle ebooks. While enrolled:

• Exclusivity: the ebook must be sold only through Amazon. The digital edition can't be on Apple, Kobo, your own website or any other store.
• Kindle Unlimited: subscribers can read your ebook, and you are paid from a monthly fund based on the pages they read.
• Promotions: you can run Kindle Countdown Deals and free book promotion days.
• Renewal: enrollment renews in 90-day terms unless you turn off automatic renewal.

Exclusivity covers the ebook only. Paperbacks, hardcovers and audiobooks can be sold anywhere.

How Kindle Unlimited pays

Each month, Amazon sets a fund for KDP Select authors. Your share depends on how many pages Kindle Unlimited readers read of your books, measured with Amazon's standardized page count. The per-page rate changes monthly and is a fraction of a cent, so income depends on volume: long books, series and fast readers generate the most page reads.

Sales to non-subscribers still pay normal KDP royalties: 70% minus delivery on Amazon.com prices from $2.99 to $12.99, or 35% otherwise.

What going wide means

Going wide means selling your ebook everywhere readers buy: Amazon (outside KDP Select), Apple Books, Kobo, Barnes & Noble, Google Play Books, library platforms, subscription services outside Amazon, and direct stores. You publish directly with each, through an aggregator such as Draft2Digital, or both.

KDP Select vs wide at a glance

Who KDP Select suits

• Authors in Kindle Unlimited-heavy genres, such as romance, thrillers, fantasy and some science fiction.
• Fast releasers, whose new books keep readers moving through a series.
• Long series, where one reader can generate thousands of page reads.
• New authors who want free exposure through Kindle Unlimited readers willing to try unknown names.
• Authors who value simplicity and one dashboard.

Who going wide suits

• Authors with international readers, especially where Kobo, Apple or local stores are strong.
• Authors in genres library readers love, including cosy mysteries, historical fiction and non-fiction.
• Non-fiction and niche authors, whose readers are spread across many stores.
• Authors with a newsletter who want to sell direct at full price.
• Authors worried about concentration risk, who don't want one company controlling their income.
• Authors pricing above $12.99, where Amazon's royalty drops to 35%.

The numbers to check

Before deciding, look at your own data, not other authors' stories. For each book or series, compare:

A worked example

Imagine a series earning $600 a month on Amazon: $400 from Kindle Unlimited page reads and $200 from sales. Going wide gives up the $400 immediately, while sales elsewhere take months to build.

• If wide stores and direct sales reach $400 a month within a year, you break even, with less dependence on Amazon.
• If they reach $150 a month, Select was the better choice for this series.

That is why the gap in the first months matters. Many authors fund the transition by going wide with a series that earns less from page reads, rather than their biggest earner.

How to test without betting everything

1. Pick one series or book.Ideally one with modest Kindle Unlimited income.
2. Turn off auto-renewaland note when the current 90-day term ends.
3. Prepare the wide listingson Apple, Kobo, B&N, Google and a direct store, ready to publish.
4. Publish everywherethe day the term ends.
5. Give it 6 to 12 months.Wide income builds slowly; don't judge after one month.
6. Compare honestlyand decide for your other books.

Making wide work

Authors who succeed wide tend to do a few things consistently:

• Put the first book in a series on promotion to draw readers into the rest.
• Go direct with the stores that sell best, and use their promotional opportunities.
• Build a newsletter so readers follow you rather than a store.
• Sell direct at full price to the readers who know you.
• Be patient. Wide is a long game.

Where BooksOasis fits for wide authors

Once your ebook is out of KDP Select, you can list it anywhere, including BooksOasis. Here, you keep 100% of the ebook price, for a flat plan, and readers can find you on genre shelves and in search.

How Kindle Unlimited readers behave

Kindle Unlimited readers pay a monthly fee and read as much as they like from the catalog. That shapes what works in Select:

• They try unknown authors readily, because it costs them nothing extra.
• They read fast and often binge whole series.
• Many rarely buy books outside Kindle Unlimited, so leaving Select can mean losing them as readers, not just the income.

If your reviews and emails come from readers who mention Kindle Unlimited, that is a strong signal Select is working for you.

Pricing when you go wide

Going wide gives you more pricing freedom. Barnes & Noble Press and Apple pay 70% at almost any price, so premium-priced box sets and non-fiction can earn more there than on Amazon above $12.99. A common wide strategy is a low or free first-in-series ebook to draw readers in, with the rest of the series at full price. Keep prices consistent across stores, since Amazon may match a lower price it finds elsewhere.

Libraries: the wide author's steady income

Through aggregators and some direct retailers, wide ebooks can be bought by libraries and lent to their members. Library income is rarely dramatic, but it tends to be steady, and library readers often go on to buy an author's other books. It is simply unavailable for ebooks in KDP Select.

Box sets and omnibus editions

Box sets are popular in both models. In Select, a long box set can generate many page reads per borrow. Wide, a box set can be priced as a premium bundle at stores without an upper price band. Some authors keep individual books wide and test a box set in Select, since each ebook is a separate title for enrollment.

A hybrid approach

You don't have to choose once for your whole catalog. Many authors run a hybrid:

Switching safely, in either direction

From KDP Select to wide

Turn off automatic renewal, wait for the 90-day term to end, then publish everywhere. Listing elsewhere before the term ends breaks the terms.

From wide to KDP Select

Remove the ebook from every other store first, and make sure it has disappeared, including from aggregators' channels and direct stores. Enroll only when it is exclusive, because Amazon can check.

Common mistakes

• Judging wide after a month. Wide stores need time and promotion.
• Forgetting stray listings. A lingering copy on another store while enrolled breaks exclusivity.
• Moving your best earner first. Test with a smaller series.
• Ignoring print. Print editions can be sold everywhere regardless of Select.
• Not building a newsletter. Without one, wide readers can't follow you from store to store.

In short

KDP Select rewards authors whose readers live in Kindle Unlimited; going wide rewards authors whose readers are spread across stores, countries and libraries. Look at your own numbers, test with one series, give wide time to work, and keep your print editions everywhere. If you go wide, add a full-margin store like BooksOasis for the readers who follow you.
