How to Self-Publish on Amazon KDP: The Complete Guide for 2026

I have published over 100 books on Amazon KDP in more than 15 languages. Some flopped. Many sold steadily. A few surprised me completely. Through all of it, one thing became clear: self-publishing on Amazon is not complicated, but doing it well requires knowing which details actually matter and which ones new authors waste weeks obsessing over.

This guide covers everything from setting up your account to scaling a catalog of multiple titles. No theory. No motivational fluff. Just the process that works, built from real experience across fiction and nonfiction in markets around the world.

What Is Amazon KDP and Why Does It Dominate Self-Publishing?

Amazon Kindle Direct Publishing is the largest self-publishing platform in the world. It gives you access to millions of readers in over a dozen marketplaces — Amazon.com, Amazon.co.uk, Amazon.de, Amazon.fr, Amazon.co.jp, and more. You can publish both ebooks and paperbacks at zero upfront cost. Amazon handles printing, fulfillment, and customer service.

The numbers are hard to argue with. Amazon controls roughly 70 to 80 percent of the ebook market and a significant share of print-on-demand paperback sales. When someone decides to buy a book, they overwhelmingly start on Amazon. That is where your book needs to be.

KDP is free to use. There are no setup fees, no inventory costs, and no minimum order quantities. You upload your files, set your price, and Amazon makes your book available within 24 to 72 hours. You earn royalties on every sale, paid monthly, approximately 60 days after the end of each royalty period.

Other platforms exist — IngramSpark, Barnes & Noble Press, Google Play Books, Apple Books — and some are worth using alongside KDP. But if you are publishing your first book, start with KDP. It has the largest audience, the fastest setup, and the most straightforward process.

Setting Up Your KDP Account the Right Way

Go to kdp.amazon.com and sign in with your existing Amazon account, or create a new one. You will need to complete your tax information and provide bank details for royalty payments. A few things to get right from the start.

Tax interview. KDP requires a tax interview before you can publish. If you are in the United States, this is straightforward. If you are outside the US, you will fill out a W-8BEN form. Many countries have tax treaties with the US that reduce withholding on your royalties from 30 percent to a lower rate — sometimes zero. Have your tax identification number ready.

Bank account. KDP can pay you via electronic funds transfer in many currencies. Set up payment for each marketplace you plan to sell in. If you only set up USD payments, your earnings from Amazon.co.uk or Amazon.de will still convert and pay out, but you may lose a few percentage points to conversion. If you use a service like Wise or Payoneer, you can receive payments in local currencies and convert on your own terms.

Author profile. Set up your Author Central profile at author.amazon.com after your first book is live. This is your author page on Amazon — add a bio, photo, and links to your other titles. It builds credibility and helps readers discover more of your work.

Preparing Your Manuscript for KDP

This is where most first-time authors get stuck. They spend weeks trying to get their formatting perfect when the actual requirements are simpler than they expect.

Ebook Formatting

KDP accepts several file formats for ebooks, but the two that matter are EPUB and DOCX. If you have a Word document, KDP can convert it. If you want more control, create an EPUB file using a tool like Calibre (free), Vellum (Mac only, paid), or Atticus (cross-platform, paid).

Key requirements for ebooks:

No fixed page sizes. Ebooks are reflowable — the reader controls font size and screen dimensions. Do not try to replicate a print layout in your ebook.
Use styles, not manual formatting. Heading 1 for chapter titles, Heading 2 for sections, Normal for body text. This creates a working table of contents automatically.
Images must be embedded, not linked. Keep image file sizes reasonable — under 5 MB each, 300 DPI is unnecessary for screens, 150 DPI works fine.
Front matter and back matter. Include a title page, copyright page, and table of contents at minimum. Back matter should include an "Also By" page linking to your other books.

If you are using AI tools to help with production, the speed gains are real. A well-structured workflow can take you from a clean manuscript to a formatted EPUB in under an hour. For a deeper look at how AI fits into book production, tools like those reviewed on AIGradeLab can help you evaluate which ones are worth your time.

Paperback Formatting

Paperback formatting is more specific because you are dealing with a physical object that has exact dimensions.

Trim size. The most common trim sizes on KDP are:

6 × 9 inches — the standard for nonfiction and most fiction. Professional-looking, comfortable to hold.
5.5 × 8.5 inches — works well for shorter books, poetry, and compact nonfiction.
5 × 8 inches — popular for fiction, slightly smaller and lighter.
8.5 × 11 inches — for workbooks, planners, coloring books, and large-format content.

Margins. KDP has minimum margin requirements that vary by page count. A 200-page book needs at least 0.75 inches on the gutter (inside) margin and 0.25 inches on the outside. Thicker books need larger gutter margins — KDP's margin calculator tells you the exact numbers.

Bleed settings. If your interior has images or design elements that extend to the edge of the page, you need bleed — an extra 0.125 inches on the top, bottom, and outside edges. Most text-only books use "no bleed," which simplifies formatting. If you are doing a photo book, coloring book, or heavily designed interior, use bleed.

File format. Submit your paperback interior as a PDF. Use PDF/X-1a or high-quality print settings. Embed all fonts. Convert all colors to CMYK if you are using color printing; grayscale for black-and-white interiors.

Page count. KDP paperbacks must be between 24 and 828 pages. Your page count directly affects your printing cost, which affects your royalty. More on that in the pricing section.

Cover Design: The Most Important Marketing Decision You Will Make

Your cover sells your book. Not your description, not your reviews, not your marketing — your cover. In the fraction of a second a shopper spends scanning search results, your cover either pulls them in or lets them scroll past.

Ebook cover specs: 2,560 × 1,600 pixels (ideal), minimum 1,000 pixels on the shortest side, maximum 10,000 pixels on the longest side. JPEG or TIFF format.

Paperback cover specs: KDP provides a cover calculator that generates a template based on your trim size, page count, and paper type. The template includes the exact spine width. Your cover file must be a PDF with 0.125-inch bleed on all sides.

Design tips from 100+ covers:

Study the top 20 books in your target category. Your cover needs to look like it belongs on that shelf while still standing out.
Typography matters more than imagery for nonfiction. A strong title in the right font, with clear hierarchy, outsells a busy illustration.
For fiction, genre conventions are non-negotiable. Romance readers expect certain visual cues. Thriller readers expect others. Break these conventions and readers will not recognize your book as being for them.
Hire a designer if your budget allows ($100 to $500 for a quality cover). If you are designing yourself, Canva and Book Brush are capable tools, but study professional covers first.
Test your cover at thumbnail size. That is how most people will see it — a tiny image in a search result or a recommendation row.

Writing a Book Description That Actually Sells

Your description is a sales page, not a summary. Most new authors write descriptions that tell the reader what the book is about. Descriptions that sell tell the reader what the book will do for them.

For nonfiction, lead with the problem your reader has, then present your book as the solution. Use bullet points for key takeaways. End with a call to action.

For fiction, create intrigue. Introduce the protagonist, the conflict, and the stakes — but never reveal the resolution. End on a question or a moment of tension that makes the reader need to know what happens next.

Amazon allows basic HTML in book descriptions: <b> for bold, <i> for italic, <br> for line breaks, and <h2> for subheadings (rendered as bold). Use these to break up your description visually. A wall of text performs worse than a structured description every time.

If writing compelling descriptions feels like a different skill than writing books — it is. Having proven templates to follow makes a significant difference. For a deep dive into description frameworks by genre, see our guide on book description templates that convert on Amazon.

Choosing Categories and Keywords: The 7-Field System

This is where most self-published authors leave money on the table. Amazon gives you two category selections and seven keyword fields during the publishing process. These determine where your book appears in Amazon's browsing structure and what search terms trigger your book in results.

The 7 Keyword Fields

Each field accepts up to 50 characters. These are not tags — they are search phrases. Think of them as the queries your ideal reader would type into Amazon's search bar. For a comprehensive strategy on maximizing these fields, read our full guide on KDP keywords strategy to rank #1 on Amazon.

Key principles:

Do not repeat words already in your title or subtitle. Amazon indexes those automatically.
Use all 50 characters in each field. Separate distinct phrases with commas.
Think like your reader, not like an author. They search for problems ("how to stop procrastinating"), not solutions ("productivity framework").
Include related terms and alternate phrasings. If your book is about budgeting, also use "money management," "personal finance," "saving money," and "financial planning."
Avoid competitor names and trademarks. Amazon can suppress your book for using trademarked terms in keywords.

Use tools like Publisher Rocket, KDP Rocket, or free Amazon search autocomplete to research what real readers are searching for. The ToolCraftKit suite also offers utilities for keyword research and analysis that can streamline this process.

Pricing Strategy: Royalties, Sweet Spots, and the Math That Matters

Ebook Pricing

KDP offers two royalty options for ebooks:

35% royalty: Available for books priced between $0.99 and $200.00. No delivery cost deducted.
70% royalty: Available for books priced between $2.99 and $9.99. A delivery cost is deducted based on file size (approximately $0.01 to $0.06 per MB for most books).

The math is clear. A book priced at $4.99 at 70% earns you roughly $3.44 per sale. That same book at $2.98 would only qualify for 35%, earning you $1.04. The $2.99 minimum for the 70% tier is a hard boundary — price below it and your per-sale earning drops dramatically.

Common pricing sweet spots:

$0.99 — launch promotions, short reads under 10,000 words, series starters to build readership
$2.99 to $3.99 — short nonfiction, novellas, fiction in competitive genres
$4.99 to $6.99 — full-length fiction and nonfiction, the highest-volume price range
$7.99 to $9.99 — premium nonfiction, comprehensive guides, established authors with strong brands

Paperback Pricing

Paperback royalties are calculated differently: list price minus printing cost times 60 percent. Your printing cost depends on page count, trim size, ink type (black and white or color), and marketplace.

A 200-page, 6×9, black-and-white paperback costs approximately $3.49 to print on Amazon.com. If you price it at $14.99, your royalty is ($14.99 − $3.49) × 0.60 = $6.90. Price your paperback so the royalty is meaningful, but keep it competitive within your genre. Check what similar books are priced at and stay within that range.

The Publishing Process: Step by Step

Once your files are ready, the actual publishing process takes about 30 minutes.

Log in to kdp.amazon.com and click "Create New Title."
Choose Kindle eBook or Paperback (you will do both separately).
Enter book details: title, subtitle, author name, description, keywords, categories.
Upload your manuscript file and cover file.
Use the previewer. KDP's online previewer shows you how your book will look. Check the first chapter, the table of contents, and any pages with special formatting. For paperbacks, download the PDF proof.
Set your price for each marketplace.
Click publish.

Your ebook typically goes live within 12 to 24 hours. Paperbacks may take 24 to 72 hours and may require an additional review if it is your first title.

Order a proof copy of your paperback before promoting it. The digital preview is useful, but holding the physical book in your hands reveals issues you will not catch on screen — margin feel, cover color accuracy, spine legibility.

Launch Week Strategy: The First 7 Days Matter

Amazon's algorithm pays close attention to a new book's performance in its first week. Strong early sales and engagement signal to the algorithm that your book deserves visibility. Here is a lean launch plan that works.

Days 1-3: Activate your network. Tell everyone who might buy — friends, family, your email list, social media followers. The goal is to concentrate as many sales as possible into a short window. This pushes your book up in the rankings, which triggers Amazon's "also bought" and "customers who viewed" recommendations.

Days 4-5: Reviews. Reach out to your advance readers and ask them to leave honest reviews. You need a minimum of 10 to 15 reviews before most casual browsers will trust your book enough to buy. Do not pay for reviews. Do not trade reviews. Amazon's detection is sophisticated and the penalties are severe.

Days 6-7: Evaluate and adjust. Check your sales dashboard, review your keywords and categories, and look at your book's search ranking for your target terms. If something is not working, adjust your keywords or description.

If you are planning to publish multiple books — and you should, because a series always outsells standalone titles — read our guide on how to plan a book series that sells on Amazon. The launch strategy for Book 2 is significantly different (and easier) than for Book 1.

Marketing Basics: AMS Ads, Social Media, and Building an Email List

Amazon Ads (AMS)

Amazon's advertising platform lets you run sponsored ads that appear in search results and on product pages. You can start with as little as $5 per day. The two main ad types are:

Sponsored Products: Your book appears in search results for specific keywords. You bid on keywords and pay per click.
Lockscreen Ads: Your book appears on Kindle device lock screens. These work best for books with strong covers and broad appeal.

Start with Sponsored Products. Target keywords from your own keyword research, competitor book titles (ASINs), and broad category terms. Set a daily budget of $5 to $10 and let the campaign run for at least two weeks before making major changes. Successful AMS campaigns typically aim for an ACoS (Advertising Cost of Sales) below 70 percent for ebooks.

Social Media and Content Marketing

Social media works for authors, but it is a slow build. The most effective platforms in 2026 for book marketing are TikTok (BookTok), Instagram (Bookstagram), YouTube (BookTube), and Pinterest for nonfiction.

Do not try to be everywhere. Pick one platform where your target readers already gather and show up consistently. Share your writing process, behind-the-scenes content, and genuine engagement with your genre's community. Promotion should be no more than 20 percent of your content.

Email List

Your email list is your single most valuable marketing asset. It is the one channel you own completely — no algorithm changes, no platform risks. Start building it with Book 1 by including a link to a free bonus (a short story, a companion guide, a checklist) in your book's back matter. Use a service like MailerLite, ConvertKit, or Mailchimp to manage your list.

9 Mistakes New Self-Published Authors Make

After watching hundreds of new authors go through this process, the same mistakes come up repeatedly.

Rushing the cover. A mediocre cover costs you more in lost sales than a good designer costs in dollars. Invest here first.

Ignoring keywords. Many authors fill in the seven keyword fields as an afterthought. Those fields directly determine whether your book appears in relevant searches.

Pricing too low or too high. Pricing your ebook at $0.99 permanently signals low value. Pricing your nonfiction at $12.99 on Kindle puts you outside the 70% royalty tier and above most of your competition. Research your genre and price accordingly.

Writing one book and waiting. The single biggest predictor of self-publishing income is catalog size. Authors with 5 to 10 books earn significantly more per title than authors with one, because each book sells the others. Start planning your next book before you launch your first.

Skipping the description. A lazy description is a closed door. Invest the time to write a description that sells — or use proven templates that convert.

Not using categories strategically. Two categories is the default, but you can have up to 10. Contact KDP support after publication and request additional relevant categories.

Expecting overnight success. Most successful self-published authors built their income over 12 to 24 months and multiple titles. Set realistic expectations and focus on building a catalog.

Not tracking finances. Self-publishing income is taxable. Expenses — cover design, editing, software, advertising — are deductible. Track everything from the start. Your future self at tax time will thank you.

Publishing only in English. Amazon operates in over a dozen marketplaces worldwide. If your content translates well, publishing in multiple languages can multiply your reach dramatically. This is one of the most underutilized strategies in self-publishing.

Scaling from One Book to a Publishing Business

The real money in self-publishing comes from building a catalog. Here is what the trajectory typically looks like.

Book 1: You learn the process. Sales are modest. You make mistakes and learn from them. Revenue: $50 to $500 per month after the initial launch period.

Books 2-5: You refine your process, improve your covers and descriptions, and start seeing compound effects. Each new book lifts the sales of your existing titles. Revenue grows to $500 to $2,000 per month.

Books 6-10+: You have systems. Your production is faster, your marketing is more efficient, and you have data to guide your decisions. Revenue can reach $2,000 to $10,000+ per month depending on your genre and marketing investment.

The key is treating it like a business from the beginning. Track your numbers, reinvest a portion of your earnings into better covers and advertising, and publish consistently. A book every one to three months is a sustainable pace for most authors.

If you want to accelerate your production timeline, AI-assisted workflows can significantly reduce the time between idea and published book. The technology has matured to the point where it genuinely helps with research, outlining, and first-draft generation — though your unique voice and expertise must drive the final product. Check AIGradeLab for honest ratings on the AI tools that actually deliver.

Planning a connected series of books is one of the most powerful strategies for building a sustainable self-publishing income. Readers who love Book 1 buy Book 2 immediately, creating a compounding sales effect. See our complete guide on how to plan a book series that sells on Amazon for the frameworks that work.
