KDP (Kindle Direct Publishing) is Amazon’s free self-publishing platform that lets you publish ebooks, paperbacks, and hardcovers to the world’s largest bookstore — with zero upfront cost.
In this guide, you’ll learn:
- How to create your KDP account and publish your first book step by step
- The royalty structures and pricing strategies that maximize your earnings
- How KDP Select, Kindle Unlimited, and Amazon Ads fit into your publishing strategy
Here’s everything you need to know about KDP in 2026.
What Is KDP (Kindle Direct Publishing)?
KDP is Amazon’s self-publishing platform that lets you publish and sell ebooks, paperbacks, and hardcovers directly on Amazon.com and 12+ international Amazon marketplaces. You upload your manuscript, design a cover, set your price, and Amazon handles production, distribution, and payments.
Amazon controls roughly 70% of all US ebook sales. That makes KDP the single most important platform for any self-published author. Over 4 million books were published in 2025, and the majority came through self-publishing platforms — with KDP as the dominant player.
Unlike traditional publishing, you keep creative control over your content, cover, pricing, and marketing. There are no query letters, no agent fees, and no waiting 12-18 months for a release date.
How Much Does KDP Cost?
KDP is completely free to use. There are no setup fees, no listing fees, and no subscription charges. Amazon makes money by taking a percentage of each sale — not by charging you upfront.
Here’s what you pay (or don’t pay) at each stage:
| Stage | Cost |
|---|---|
| Account creation | Free |
| Ebook publishing | Free |
| Paperback publishing | Free (print-on-demand) |
| Hardcover publishing | Free (print-on-demand) |
| ISBN for ebook | Free (Amazon assigns one) |
| ISBN for paperback | Free (Amazon-provided) or bring your own |
| Amazon Ads | Optional — you set your budget |
The only costs you might incur are optional: professional cover design, editing services, or paid advertising. But the platform itself costs nothing.
How to Set Up Your KDP Account
Setting up your KDP account takes about 15 minutes. Here’s the process:
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. Amazon requires tax details before you can publish. US-based authors fill out a W-9. International authors fill out a W-8BEN. KDP walks you through this with an online interview.
Step 3: Set up your payment method. Choose how you want to receive royalties — direct deposit (recommended) or check. You’ll need your bank routing and account numbers.
Step 4: Enter your author/publisher name. This is the name that appears on your books. You can use your real name, a pen name, or a publisher imprint.
Once your account is verified, you can start publishing immediately.
How to Publish a Book on KDP (Step by Step)
Publishing on KDP follows a straightforward three-phase process: create your book details, upload your content, and set your pricing.
Phase 1: Enter Your Book Details
Start by clicking “Create New Title” in your KDP Bookshelf. You’ll choose between ebook, paperback, or hardcover.
Then fill in the metadata:
- Title and subtitle — Include relevant keywords naturally. Your subtitle is prime real estate for discoverability.
- Author name — Your pen name or real name.
- Description — This is your book’s sales pitch. Use all 4,000 characters. Format with bold text and bullet points for scannability.
- Keywords — You get 7 keyword slots. Use specific, searchable phrases — not single words. Check our Amazon keywords guide for strategy.
- Categories — Pick 2-3 categories where your book fits. Niche categories with less competition give you a better shot at ranking.
Phase 2: Upload Your Content
Manuscript format: KDP accepts DOCX, EPUB, KPF (Kindle Create format), and PDF (print only). For ebooks, EPUB or KPF produce the best results. For paperback and hardcover, use a properly formatted PDF.
If you’re writing your book with AI assistance, tools like Chapter can export directly to formats KDP accepts — saving you hours of manual formatting.
Our Pick — Chapter
Chapter’s AI writing platform helps you write, outline, and format your book in one place. Export your finished manuscript directly to KDP-ready formats without wrestling with Word templates or third-party converters.
Best for: Authors who want to write and format their book in a single tool Pricing: $97 one-time (nonfiction) | Varies (fiction) Why we built it: Getting a manuscript from draft to KDP-ready format shouldn’t require three different apps.
Book cover: Your cover is the single most important marketing asset for your book. KDP provides a free Cover Creator tool, but most successful authors invest in a professional cover. Your cover file needs to be a high-resolution PDF or TIFF that meets Amazon’s exact specifications.
Learn more about formatting in our book formatting guide.
Phase 3: Set Your Pricing and Rights
This is where you decide how much you’ll earn per sale.
Territories: Choose whether to sell worldwide or restrict to specific regions. In almost every case, select all territories.
Pricing: Set your list price in each marketplace. Amazon shows you estimated royalties in real time as you adjust the price.
Royalty plan (ebooks only): Choose between the 35% and 70% royalty options — covered in detail in the next section.
Click “Publish” and your book goes live within 72 hours.
KDP Royalty Rates Explained
Understanding KDP’s royalty structure is essential for pricing your book correctly.
Ebook Royalties
You choose between two royalty plans for each ebook:
| Feature | 35% Royalty | 70% Royalty |
|---|---|---|
| Price range | $0.99 – $200 | $2.99 – $9.99 |
| Delivery fee | None | ~$0.15 per MB |
| Territories | All Amazon marketplaces | Select territories only |
| Price matching | Amazon may match lower prices | You control pricing |
The 70% plan is almost always the better choice if your ebook is priced between $2.99 and $9.99. The delivery fee is minimal — typically $0.10 to $0.30 — and your net royalty far exceeds the 35% option.
Example: A $4.99 ebook with a 1MB file earns $3.35 at 70% (after delivery fee) versus $1.75 at 35%.
Paperback and Hardcover Royalties
Print royalties work differently. As of June 2025, Amazon changed the paperback royalty rate from 60% to 50% of list price minus printing costs.
Your royalty = (List price x 50%) - Printing cost
Printing costs depend on page count, ink type (black-and-white vs. color), trim size, and marketplace. A 200-page black-and-white paperback in the US costs approximately $3.25 to print.
Example: A 200-page paperback priced at $14.99 earns: ($14.99 x 0.50) - $3.25 = $4.25 per sale.
Hardcover royalties follow a similar formula but with higher printing costs — typically $7-$10 per book depending on specifications.
For a deeper breakdown, see our book royalties guide.
What Is KDP Select (and Should You Enroll)?
KDP Select is Amazon’s optional exclusivity program for ebooks. When you enroll, your ebook becomes exclusive to Amazon for 90 days — you can’t sell it on Apple Books, Kobo, Barnes & Noble, or any other platform.
What You Get With KDP Select
- Kindle Unlimited access. Your book enters the KU library, where subscribers can read it for free. You earn based on pages read (typically $0.004-$0.005 per page).
- Kindle Countdown Deals. Time-limited promotional pricing that shows a countdown clock and crossed-out original price.
- Free Book Promotions. Make your ebook free for up to 5 days per 90-day enrollment period.
KDP Select: Who Should Enroll
KDP Select works best for:
- New authors building an audience from zero
- Genre fiction authors in romance, thriller, sci-fi, and fantasy — genres where Kindle Unlimited readership is highest
- Authors using rapid-release strategies who publish multiple books per year
KDP Select is less ideal for:
- Nonfiction authors whose readers shop across platforms
- Authors with established audiences on Apple Books or Kobo
- Anyone uncomfortable with platform exclusivity
The enrollment auto-renews every 90 days. You can opt out before each renewal date if exclusivity isn’t working for you.
How to Format Your Manuscript for KDP
Proper formatting prevents rejected uploads, display errors, and negative reviews.
Ebook Formatting
Ebooks are reflowable — the text adjusts to the reader’s screen size and font preferences. Key formatting rules:
- Use heading styles (Heading 1, Heading 2) instead of manually bolding and resizing text
- Don’t use hard page breaks except between chapters
- Embed fonts if using anything beyond standard serif/sans-serif
- Keep images under 5MB each and use JPEG format
- Include a linked table of contents — Amazon requires this for ebooks over 10 pages
Amazon’s free Kindle Create tool converts Word documents to KPF format with professional templates. Kindle Previewer lets you see exactly how your book looks on different Kindle devices before publishing.
Print Formatting (Paperback and Hardcover)
Print books require exact specifications:
- Trim size: Choose from standard options like 5” x 8”, 5.5” x 8.5”, or 6” x 9”. The 6” x 9” trim size is the most popular for nonfiction.
- Margins: KDP has minimum margin requirements that increase with page count. A 300-page book needs at least 0.875” gutter margin.
- Bleed: If your cover or interior has images that extend to the page edge, enable bleed settings (0.125” on each side).
- Resolution: Interior images must be at least 300 DPI for print.
For detailed formatting templates, check our book formatting guide.
KDP Categories and Keywords Strategy
Choosing the right categories and keywords directly impacts your book’s visibility on Amazon.
Categories
Amazon lets you select up to three browse categories (previously two — this expanded in 2024). Pick categories that are:
- Relevant to your book’s actual content
- Specific enough that you can rank on the first page
- Active enough that readers actually browse them
You can request additional categories through Amazon Author Central after publishing. Some authors successfully appear in 8-10 categories.
Keywords
Your 7 keyword slots are crucial for Amazon search visibility. Each slot can hold a phrase up to 50 characters.
Effective keyword strategies:
- Use specific multi-word phrases (“cozy mystery series small town”) instead of single words (“mystery”)
- Include terms readers actually search for — check Amazon’s search autocomplete for ideas
- Don’t repeat words already in your title or subtitle
- Include alternate spellings or related terms your audience might use
For a complete keyword strategy, see our Amazon keywords for books guide.
Amazon Advertising for KDP Books
Amazon Ads (formerly AMS) lets you promote your book directly in Amazon search results and on competitor book pages. It’s a pay-per-click system — you only pay when someone clicks your ad.
Ad Types for KDP Authors
- Sponsored Products: Your book appears in search results and on product pages. This is the most common and effective ad type for books.
- Sponsored Brands: A banner ad featuring your author brand and multiple books. Best for authors with 3+ titles.
- Lock Screen Ads: Appear on Kindle device lock screens. Available for ebooks only.
Getting Started With Amazon Ads
Start with a daily budget of $5-$10 and automatic targeting. Let Amazon’s algorithm find your audience for 7-14 days. Then analyze which keywords and targets are converting, and create manual campaigns focused on your winners.
Most successful KDP authors spend 10-20% of their royalties on advertising, especially during launch periods.
KDP vs. Other Self-Publishing Platforms
KDP dominates the market, but it’s not the only option. Here’s how it compares to the other major platforms:
| Platform | Ebook Royalty | Print Option | Exclusivity Required | Best For |
|---|---|---|---|---|
| Amazon KDP | Up to 70% | Paperback + Hardcover | No (unless KDP Select) | Maximum reach and sales |
| IngramSpark | 40-45% | Paperback + Hardcover | No | Bookstore and library distribution |
| Draft2Digital | Up to 70% | Via partnerships | No | Multi-platform distribution |
| Apple Books | 70% | No | No | Apple ecosystem readers |
| Kobo Writing Life | 70% | No | No | International readers |
Most authors publish on KDP as their primary platform and use a distributor like IngramSpark or Draft2Digital for wider reach. See our full self-publishing platforms comparison for details.
Common KDP Mistakes to Avoid
These are the errors that cost new KDP authors the most time, money, and sales:
- Skipping professional editing. Typos and grammar errors lead to negative reviews. Budget for at least a proofread before publishing.
- Using a low-quality cover. Readers judge books by their covers — literally. A $50 premade cover outperforms a DIY design almost every time.
- Pricing too high or too low. Ebooks under $2.99 earn only 35% royalties. Ebooks over $9.99 also drop to 35%. The sweet spot is $2.99-$6.99 for most genres.
- Ignoring your book description. Your description is a sales page. Write it like ad copy — hook, benefits, social proof, call to action.
- Publishing without a launch strategy. A book without marketing is invisible. Plan your book launch before you hit publish.
- Not tracking your sales. Your KDP Dashboard shows real-time sales, royalties, and page reads. Check it regularly and adjust your strategy based on the data.
How to Write Your Book Faster With AI
One of the biggest barriers to publishing on KDP is actually finishing your manuscript. AI writing tools have made this dramatically faster — especially for nonfiction.
Our Pick — Chapter
Chapter is an AI-powered book writing platform used by 2,147+ authors to create 5,000+ books. It helps you outline, draft, and edit your manuscript in a guided workflow — then export directly to KDP-ready formats. Featured in USA Today and the New York Times.
Best for: First-time authors who need structure and speed Pricing: $97 one-time (nonfiction) | Varies (fiction)
Chapter works particularly well for KDP authors because it combines the writing and formatting steps into one workflow. Instead of writing in Google Docs, formatting in Word, and converting to EPUB separately, you do everything in one place.
Authors using Chapter have reported results including $13,200 from a single book, a $60K launch in 48 hours, and landing speaking gigs for 20,000-person audiences — all from books written and published through KDP.
How Long Does It Take to Publish on KDP?
You can publish a book on KDP in as little as 24-72 hours once your manuscript and cover are ready.
Here’s the typical timeline:
| Stage | Timeline |
|---|---|
| Writing your book | 2 weeks – 12 months (varies widely) |
| Editing and proofreading | 1-4 weeks |
| Cover design | 3-7 days |
| Formatting for KDP | 1-3 days |
| KDP review after upload | 24-72 hours |
The publishing step itself is fast. The bottleneck is almost always the writing and editing phase. Using AI tools like Chapter can compress the writing timeline from months to weeks.
After you click “Publish,” Amazon reviews your book to ensure it meets their content guidelines. Most books go live within 72 hours. Ebooks typically appear faster than print editions.
Can You Make Money With KDP?
Yes — but your results depend on your genre, marketing effort, and how many books you publish.
Here’s a realistic breakdown of what KDP authors earn:
- Most KDP authors earn under $1,000/year. This includes the vast majority of one-book authors who publish without a marketing strategy.
- Active indie authors who publish multiple books, invest in covers and editing, and run Amazon Ads typically earn $1,000-$50,000/year.
- Top-performing indie authors earning six or seven figures usually have 10+ books, a loyal readership, and sophisticated marketing systems.
The self-publishing industry is projected to reach $22 billion by 2026. The opportunity is real — but so is the competition. Success on KDP requires treating your book like a business, not just a creative project.
For more on author earnings, see our how much do authors make guide.
Is It Legal to Publish AI-Written Books on KDP?
Yes, with disclosure requirements. Amazon updated its KDP content guidelines in 2023 to address AI-generated content.
Amazon’s current policy:
- You must disclose if your book content was AI-generated (not just AI-assisted)
- AI-assisted content (where you use AI as a tool but substantially edit and shape the output) is treated the same as traditionally written content
- AI-generated cover images require disclosure
- You’re responsible for all content in your book, regardless of how it was created
The key distinction is between AI-generated (the AI wrote it and you published it as-is) and AI-assisted (you used AI during your process but the final product reflects your creative direction and editing).
