Kindle Direct Publishing

Kindle Direct Publishing (KDP) is Amazon’s self-publishing service for eBooks, paperbacks, and hardcovers. It suits authors who want to sell books through Amazon and offer print editions without buying inventory in advance. Its appeal is a free publishing route with flexible formats; its limits are print-cost deductions, royalty conditions, and an exclusivity requirement for Kindle eBooks enrolled in KDP Select.

Overview

KDP gives authors a way to publish books for Amazon storefronts while retaining full rights to their work. Paperbacks and hardcovers are printed on demand, so authors do not need to stock copies before orders arrive. Global fulfillment and Expanded Distribution—to bookstores, online retailers, libraries, and academic institutions—make it useful for authors looking beyond a single Amazon storefront, though the service remains centered on books rather than general merchandise.

Its storefronts include Amazon.com, Amazon.ca, Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.it, Amazon.es, Amazon.nl, Amazon.pl, Amazon.se, Amazon.ie, Amazon.com.be, Amazon.co.jp, and Amazon.com.au. That breadth is most relevant to writers whose readers already shop on Amazon.

Key features

Manuscript preparation

KDP accepts eBook manuscripts in DOC, DOCX, KPF, and EPUB, along with HTML, RTF, TXT, and PDF. Kindle Create runs on Windows and Mac and can prepare manuscripts exported from Microsoft Word, Apple Pages, or Google Docs. Design and mockup tools help authors prepare book presentation, while sample chapters and Kindle Instant Book Previews give readers a way to preview work.

Royalties and print-on-demand

eBooks have 35% and 70% royalty options; the 70% rate is limited to certain territories and subject to delivery costs. Print books can earn up to 60% royalties, with printing costs deducted from print royalties when an order ships. The on-demand model avoids advance inventory, but those deductions mean a print sale does not translate directly into the advertised royalty share.

KDP Select

KDP Select is a free 90-day program for Kindle eBooks. It includes Kindle Unlimited and eligibility for Free Book Promotions and Kindle Countdown Deals, which may suit authors seeking those promotional options. The trade-off is strict for the enrolled eBook: during each enrollment period, it must be exclusive to the Kindle Store. Print, video, audio, and other formats may still be distributed elsewhere.

Publishing limits

KDP caps creation and first-time submission at up to two new titles per book format each week, with separate limits for each format. It does not accept magazines, periodicals, calendars, or spiral-bound books, so it is a poor fit for those publication types. KDP recommends two-step verification and a strong, unique Amazon account password; authors can request phone support through the KDP Contact Us Form.

Pricing

KDP’s publishing plan costs free, billed as free to publish. It covers eBooks, paperbacks, and hardcovers, but excludes magazines, periodicals, calendars, and spiral-bound books. Authors do not pay a publishing subscription, though printing costs are deducted from print royalties when an order ships. This makes KDP accessible to authors who want to publish without an upfront platform fee, but the free entry point should not be mistaken for cost-free print fulfillment.

KDP Select also costs nothing and runs for 90 days per enrollment. Its promotional and Kindle Unlimited eligibility may be worth the term for authors willing to keep the Kindle eBook exclusive to Amazon; writers prioritizing broad digital distribution should avoid that commitment.

Platforms

KDP is available on Android, iOS, macOS, web, and Windows. Kindle Create is specifically available for Windows and Mac, with support for manuscripts exported from Word, Pages, and Google Docs.

Who it's for

KDP is a strong fit for independent authors publishing conventional books who want Amazon storefront access, print-on-demand editions, and control of their rights without a publishing fee. It is less suitable for creators producing excluded formats, or for Kindle eBook authors who require simultaneous distribution through competing digital stores while enrolled in KDP Select.

Pros and cons

• Pros: Free-to-publish plans cover eBooks, paperbacks, and hardcovers, lowering the upfront barrier for authors.
• Pros: Print-on-demand avoids buying inventory in advance, and Expanded Distribution can extend print availability beyond Amazon.
• Pros: Authors retain full rights, with manuscript formats and creation tools that accommodate common writing workflows.
• Cons: Print costs come out of print royalties when orders ship, reducing the amount authors keep from each sale.
• Cons: The 70% eBook royalty applies only in certain territories and is subject to delivery costs.
• Cons: KDP Select requires Kindle eBook exclusivity for each 90-day enrollment period, limiting digital distribution choices.
• Cons: Weekly submission caps and excluded publication formats restrict authors with high-volume or nonstandard publishing needs.

Verdict

Choose KDP if you are an independent author who wants Amazon reach, print-on-demand books, and a free publishing entry point while keeping your rights. Its main advantage is a combined route to digital and physical book sales without advance print inventory. Look elsewhere if your format is excluded or if you need a Kindle eBook distributed beyond Amazon during a KDP Select enrollment.
