Amazon KDP for self-publishing is a free platform that lets you publish ebooks, paperbacks, and hardcovers to the world’s largest bookstore. You keep up to 70% royalties on ebook sales, never hold physical inventory, and your book can be live within 72 hours of uploading.
This guide walks you through exactly how Amazon Kindle Direct Publishing works — from creating your account to collecting your first royalty payment.
What is Amazon KDP?
KDP stands for Kindle Direct Publishing. It is Amazon’s self-publishing arm, and it handles three formats: Kindle ebooks, paperback books, and hardcover books. Amazon launched the platform in 2007 alongside the original Kindle device, and it has since become the dominant self-publishing platform worldwide.
The key facts:
- Cost to publish: Free. KDP charges nothing to upload or list your book.
- Print model: Print-on-demand. Amazon prints paperbacks and hardcovers only when a customer orders them, so you carry zero inventory.
- Ebook delivery: Instant. Kindle ebooks deliver wirelessly to any Kindle device or app.
- Royalty options: 35% or 70% for ebooks. Print royalties are calculated after printing costs.
- Global reach: Available in over 45 languages across more than 10 countries through Amazon’s marketplace network.
KDP is not the only way to self-publish, but it controls roughly 70-80% of the global ebook market. If you are publishing one book on one platform, this is the one most authors start with.

How to set up your KDP account
Setting up a KDP account takes about 10 minutes. You need an Amazon account (or you can create one during signup), your bank details for royalty payments, and your tax information.
Step 1: Go to kdp.amazon.com and sign in with your existing Amazon account or create a new one.
Step 2: Complete your tax information. If you are in the United States, KDP will walk you through a W-9 form. International authors complete a tax interview that determines withholding rates based on your country’s tax treaty with the US.
Step 3: Add your bank account for royalty deposits. KDP pays via electronic funds transfer (EFT) in most countries. You can add separate bank accounts for different Amazon marketplaces (US, UK, Germany, etc.) or route everything to one.
Step 4: Set up your author profile. While optional, completing your Amazon Author Central profile adds your photo, bio, and blog to your book listings. This builds credibility with readers browsing your page.
Once your account is active, you can start uploading books immediately.
How to publish your book on KDP
The publishing process has three main sections that KDP walks you through for every title: book details, content upload, and pricing.
Book details
This is where you enter the metadata that helps readers find your book:
- Title and subtitle — Keep your title clear and searchable. Your subtitle is a strong place to include relevant keywords.
- Author name — Your legal name or pen name. You can add contributors (editors, illustrators) here too.
- Description — Up to 4,000 characters. This is your book’s sales pitch on its Amazon listing page. Write it like ad copy, not a synopsis. For tips on optimizing this, read our guide on Amazon keywords for books.
- Keywords — You get seven keyword slots. Each can be a phrase up to 50 characters. Choose terms readers actually search for.
- Categories — Select up to three categories (called Browse Categories). Picking specific subcategories gives you a better shot at appearing on bestseller lists. See our full guide on how to choose Amazon book categories.
Content upload
KDP accepts manuscript files in several formats. For ebooks, the cleanest options are EPUB or DOCX. For paperbacks and hardcovers, you need a print-ready PDF with proper trim size, margins, and bleed settings.
Cover requirements: Your cover must meet minimum resolution requirements (at minimum 1000 pixels on the longest side for ebooks, 300 DPI for print). KDP offers a free Cover Creator tool, but most successful authors invest in professional cover design. A poor cover is the single fastest way to kill your sales.
Interior formatting: Ebooks and print books have different formatting needs. Ebooks reflow text to fit the reader’s screen, so fixed layouts break on smaller devices. Print books need exact page dimensions, proper margins, and page numbers.
After uploading, use KDP’s online previewer to check how your book looks across devices. Fix any formatting issues before publishing — readers notice and mention them in reviews.
Pricing and royalties
KDP offers two royalty structures for ebooks:
| Royalty Plan | Rate | Price Range | File Delivery Cost |
|---|---|---|---|
| 35% royalty | 35% of list price | $0.99–$200.00 | None |
| 70% royalty | 70% of list price | $2.99–$9.99 | Per-MB delivery fee |
Most authors choose the 70% royalty option and price their ebooks between $2.99 and $9.99. The 35% option exists mainly for books priced outside that range.
For paperbacks and hardcovers, your royalty is 60% of the list price minus the printing cost. Printing cost depends on page count, trim size, ink type (black or color), and marketplace. KDP provides a printing cost calculator so you can estimate before setting your price.

Writing your book before you publish
KDP handles the publishing side. But you still need a finished, polished manuscript before you upload anything.
If you are writing nonfiction — a how-to guide, memoir, business book, or authority title — AI writing tools can cut your drafting time significantly without sacrificing quality.
Our Pick — Chapter
Chapter.pub is an AI book writing platform built specifically for nonfiction authors. It helps you outline, draft, and refine a full-length book — not just generate random text. Over 2,147 authors have used it to produce more than 5,000 books.
Best for: Nonfiction authors who want a structured writing process with AI assistance Pricing: $97 one-time Why we built it: Most AI tools generate generic content. Chapter walks you through a real book-writing workflow, from outline to polished manuscript.
If you are writing fiction, the process is different. You can explore AI novel writing tools or write your manuscript in any word processor and export to DOCX or EPUB for KDP upload.
Regardless of how you write, professional editing is non-negotiable. Raw drafts — whether human-written or AI-assisted — need at least one round of developmental editing and one round of copy editing before they are ready for readers.
KDP Select and Kindle Unlimited
When publishing an ebook, KDP asks whether you want to enroll in KDP Select. This is a separate, optional program with trade-offs worth understanding.
What you get with KDP Select:
- Your ebook is included in Kindle Unlimited (KU), Amazon’s subscription reading service. You earn royalties based on pages read, not copies sold.
- Access to promotional tools: Kindle Countdown Deals and Free Book Promotions.
- Higher royalty rates in some international markets (India, Japan, Brazil, Mexico).
What it costs you:
- Exclusivity. Your ebook cannot be sold anywhere else — not on your website, not on Apple Books, not on Kobo. The exclusivity period is 90 days, and it auto-renews unless you opt out.
- Variable income. KU page-read royalties fluctuate monthly based on a shared fund. The per-page rate has ranged from roughly $0.004 to $0.005 in recent years.
KDP Select works best for fiction authors in genres where Kindle Unlimited readership is high — romance, thriller, sci-fi, and fantasy in particular. Nonfiction authors who sell primarily through their own marketing (websites, email lists, courses) often do better going wide across multiple platforms.

ISBNs on Amazon KDP
ISBNs confuse a lot of first-time publishers. Here is what you need to know:
- Ebooks: Amazon assigns a free ASIN (Amazon Standard Identification Number) to every Kindle ebook. You do not need an ISBN for ebooks sold exclusively on Amazon.
- Paperbacks and hardcovers: KDP provides a free ISBN for print books. The publisher of record will be listed as “Independently Published.”
- Your own ISBN: If you want your publishing imprint listed as the publisher, you need to purchase your own ISBN from Bowker (the official US ISBN agency) or your country’s equivalent.
Using KDP’s free ISBN is perfectly fine for most self-published authors. Buying your own makes sense if you are building a publishing brand or plan to distribute through bookstores via IngramSpark alongside your KDP listing.
Amazon’s AI content policy for KDP
If you use AI tools to help write, illustrate, or translate your book, Amazon requires disclosure during the KDP upload process. This is a policy Amazon introduced in 2023 and continues to enforce.
The key distinction:
- AI-generated content (where AI created the content) — requires disclosure
- AI-assisted content (where AI helped you edit, brainstorm, or refine your own writing) — does not require disclosure
Using tools like Chapter.pub, Grammarly, or ProWritingAid falls under AI-assisted and does not trigger disclosure requirements. Generating entire chapters with ChatGPT and publishing them with minimal editing would be considered AI-generated.
For the full breakdown of what is and is not allowed, read our detailed guide on Amazon KDP and AI books rules.
How long does it take to publish on KDP?
Once you click “Publish” in your KDP dashboard, here is the typical timeline:
- Ebooks: 24–72 hours to appear on Amazon
- Paperbacks: 3–5 business days for the listing to go live, plus additional time for the “Look Inside” preview to generate
- Hardcovers: Similar to paperbacks, 3–5 business days
If KDP flags your book for manual review — which happens more often with AI-disclosed content, certain sensitive categories, or books with cover images that need verification — the process can take up to two weeks.
Getting paid: KDP royalty payments
KDP pays royalties approximately 60 days after the end of each month. So books sold in January are paid around the end of March.
Payment methods include:
- Electronic funds transfer (EFT) — Available in most countries. No fees.
- Wire transfer — For marketplaces where EFT is not available. Subject to a per-transfer fee.
- Check — Slowest option. Available as a fallback.
Each Amazon marketplace (US, UK, Germany, France, etc.) has its own payment threshold. For the US marketplace, the minimum is $10 for EFT. You can track your earnings in real time through the KDP dashboard’s reports section.
Common mistakes to avoid
- Publishing without professional editing. Readers leave one-star reviews for typos and formatting errors. Budget for at least copy editing before you hit publish.
- Ignoring your book description. Your description is a sales page. A weak description kills conversions no matter how good your book is. Study successful books in your category and write copy that sells.
- Choosing the wrong categories. Generic categories bury your book. Specific subcategories give you a realistic shot at appearing on Amazon’s bestseller lists. See our category selection guide.
- Skipping the previewer. KDP’s online previewer exists for a reason. Check every page of your print book and test your ebook on multiple device views before publishing.
- Expecting instant sales. Publishing on Amazon is not a marketing strategy. You still need to drive readers to your listing through Amazon ads, email marketing, social media, or book launch strategies.
FAQ
Is Amazon KDP really free?
Yes. There is no cost to create an account, upload your book, or list it for sale. Amazon makes money by taking a percentage of each sale (the inverse of your royalty rate) and by charging printing costs for physical books.
How much money can you make self-publishing on KDP?
Income varies enormously. Some authors earn nothing. Others earn six figures annually. Your earnings depend on your genre, book quality, pricing, marketing effort, and how many titles you publish. Authors who treat publishing as a business and build a backlist of multiple books tend to earn the most. For realistic numbers, see how much do authors make.
Can I publish on other platforms and Amazon at the same time?
Yes, as long as you do not enroll in KDP Select. Without KDP Select, your ebook can be sold simultaneously on Apple Books, Kobo, Barnes & Noble, Google Play, and your own website. Your paperback and hardcover editions are never exclusive to Amazon regardless of KDP Select enrollment.
Do I need a business license to publish on KDP?
No. Individual authors can publish under their personal name or a pen name without a business license. If you plan to publish multiple books and want to operate under a publishing imprint, forming an LLC is common but not required by Amazon.
How do I market my book after publishing?
Publishing is step one. Marketing is everything after. Start with Amazon ads for authors, build an email list, get book reviews on Amazon, and develop a book launch checklist before your publish date. For a complete overview, read our guide on how to market a self-published book.
