How to Self-Publish on Amazon KDP in 2026: Complete Step-by-Step Guide

Amazon Kindle Direct Publishing (KDP) has made self-publishing accessible to anyone with a story to tell or knowledge to share. Publishing costs nothing up front, the top royalty rate is 70%, and most titles go live within 72 hours of hitting publish. Whether you're publishing your first novel, a cookbook, a business guide, or a children's book, this guide walks you through every step of the KDP publishing process.

What you'll learn: Account setup, manuscript formatting, cover requirements, metadata optimization, pricing strategies, and launch marketing. By the end, you'll have everything you need to publish your first book on Amazon.

What is Amazon KDP?

Amazon Kindle Direct Publishing (KDP) is Amazon's self-publishing platform. It allows anyone to publish ebooks and paperbacks for free, reaching millions of Amazon customers worldwide. There are no upfront costs. Amazon makes money by taking a percentage of each sale.

Key benefits of KDP:

• Free to publish: No setup fees, no printing costs for ebooks
• Global reach: Your book becomes available in 13 Amazon marketplaces
• Fast publishing: Books go live within 24-72 hours
• Keep your rights: You retain copyright and can unpublish anytime
• Real-time tracking: Monitor sales and royalties in your dashboard
• Print on demand: Paperbacks printed only when ordered (no inventory)

KDP is ideal for authors who want control over their publishing journey without the gatekeeping of traditional publishers. You set your price, design your cover, and keep up to 70% of royalties.

Step 1: Create Your Amazon KDP Account

If you already have an Amazon account, you can use it to sign in to KDP. If not, you'll create a new account during setup.

To set up your KDP account:

1. Go to kdp.amazon.com
2. Sign in with your Amazon account or create a new one
3. Complete your author/publisher profile
4. Enter your tax information (required before you can publish)
5. Set up your payment method for royalties

Tax information: US authors complete a W-9. International authors complete a W-8BEN. Amazon withholds taxes on royalties from certain countries unless you provide tax treaty documentation. Complete this step early to avoid delays when you're ready to publish.

Payment setup: Add your bank account details for electronic fund transfers. Payments are made approximately 60 days after the end of each month (so January sales are paid in late March). You can also choose payment by check, though this takes longer and may have minimum thresholds.

Step 2: Write and Prepare Your Manuscript

Before you can publish, you need a finished manuscript. This is where most aspiring authors get stuck. The blank page is intimidating, and writing a full book takes time.

Options for creating your manuscript:

• Write it yourself: The traditional approach. Use Word, Google Docs, or Scrivener
• Use AI assistance: Tools like AI book writers can help generate drafts from your ideas
• Hire a ghostwriter: Work with a professional writer to bring your vision to life
• Repurpose existing content: Turn blog posts, courses, or presentations into book format

For non-fiction authors especially, AI-assisted writing can dramatically speed up the process. You provide the expertise, outline, and key points. The AI helps expand them into polished chapters.

Manuscript Formatting Requirements

KDP accepts several file formats for ebooks:

• DOC/DOCX: Microsoft Word format (most common)
• EPUB: Standard ebook format
• KPF: Kindle Create format (recommended for complex layouts)
• HTML, RTF, TXT and PDF: Accepted, but rarely the best choice for a reflowable ebook

One format to stop using: MOBI. Amazon stopped accepting MOBI files for fixed-layout ebooks in March 2025, and Kindle Create's KPF output is the replacement Amazon points authors to. Older guides that tell you to convert to MOBI before uploading are out of date.

Basic formatting rules:

• Use standard fonts (Times New Roman, Arial, Georgia)
• Use Word's heading styles for chapter titles (Heading 1)
• Insert page breaks between chapters (not multiple returns)
• Avoid manual spacing. Use paragraph settings instead
• Include a table of contents using Word's TOC feature
• Keep images at 300 DPI, RGB color mode

For complex books (cookbooks, children's books, heavily illustrated guides), use Kindle Create, Amazon's free formatting tool. It handles layout-intensive content better than Word alone.

If you are publishing a paperback edition, your interior file must be a print-ready PDF with exact trim dimensions and asymmetric gutter margins. See our complete guide to creating a print-ready PDF for KDP paperback for the full specification table and step-by-step export walkthrough.

Step 3: Design Your Book Cover

Your cover is your book's most important marketing asset. On Amazon, buyers see thumbnails first. A professional cover signals quality. An amateur cover signals "skip this."

KDP cover specifications:

• Ebook covers: 1,600 pixels wide by 2,560 pixels tall is Amazon's ideal size, at a height-to-width ratio of at least 1.6:1, in RGB, saved as JPEG or TIFF
• Ebook cover minimum: 625 x 1,000 pixels. Anything smaller is rejected, and anything close to it looks soft on a modern screen
• Paperback covers: Dimensions vary by trim size and page count. Use the KDP cover calculator
• File size: Under 50MB
• Resolution: Amazon recommends 300 PPI source artwork for ebook covers, and 300 DPI is the floor for print interiors

Cover design options:

• AI cover generators: Create professional covers in minutes. Inkfluence AI includes cover generation
• Canva/Book Brush: DIY tools with book cover templates
• Hire a designer: Fiverr, 99designs, or professional cover artists ($50-$500+)
• KDP Cover Creator: Amazon's free tool (basic, but functional)

Cover design tips for 2026:

• Check your genre's bestseller covers for current trends
• Ensure title is readable at thumbnail size
• Use contrasting colors for visibility
• Keep design clean. Cluttered covers fail
• Test on mobile devices (where most browsing happens)

Step 4: Set Up Your Book Details (Metadata)

Metadata is the information Amazon uses to categorize your book and show it to the right readers. Getting this right is critical for discoverability.

Title and Subtitle

Your title should be clear and include relevant keywords where natural. Subtitles are optional for fiction but highly recommended for non-fiction.

Examples:

• Good non-fiction: "Meal Prep Mastery: 75 Easy Recipes for Busy Weeknights"
• Good fiction: "The Last Lighthouse Keeper" (genre signals through cover/category)

Book Description

Your description is your sales pitch. It appears on your book's product page and needs to hook readers, communicate value, and prompt them to buy.

Description best practices:

• Open with a hook that identifies the reader's problem or desire
• For fiction: Set up the conflict without spoilers
• For non-fiction: Promise specific outcomes
• Use HTML formatting (bold, bullets) to improve readability
• End with a call to action
• Keep under 4,000 characters

Use a book description generator to create conversion-optimized descriptions that follow Amazon's best practices.

Keywords (7 Slots)

Amazon gives you 7 keyword fields to help readers find your book. These are invisible to shoppers but power Amazon's search.

Keyword strategy:

• Don't repeat words already in your title
• Use phrases, not single words ("healthy dinner recipes" not just "recipes")
• Include synonyms and related terms
• Add common misspellings your audience might use
• Research what successful competitors target

Our KDP SEO checklist provides a complete keyword optimization strategy.

Categories (3 Selections)

You choose up to 3 categories during publishing. Categories determine where your book appears in Amazon's browse structure and which bestseller lists you can rank on.

This changed, and a lot of guides are still wrong about it. KDP used to give you 2 categories at upload plus an email route to request up to 10 more after publishing. Amazon retired that request process in 2023 and made 3 self-selected categories the hard limit. If a blog post tells you to email KDP support for extra categories, it predates the change and the request will not be actioned.

Category tips:

• Choose the most specific relevant categories. All 3 slots are worth using
• Check category competition (fewer books = easier to rank)
• Your keywords can pull you into some specialised subcategories that are not offered in the category picker, so treat keywords and categories as one exercise
• Look at where successful similar books are categorized

Step 5: Choose Your Pricing and Royalty Rate

KDP offers two royalty options for ebooks:

35% Royalty

• Available up to $200. The minimum depends on file size: $0.99 under 3MB, $1.99 from 3MB to 10MB, $2.99 above 10MB
• No delivery costs deducted
• Available in all Amazon territories

70% Royalty

• Available for prices between $2.99 and $12.99 on Amazon.com, with equivalent bands in the other marketplaces
• Delivery costs deducted at $0.15 per megabyte of file size in the US store
• Available in select territories only. In Brazil, Japan, Mexico and India the 70% rate requires KDP Select enrolment
• Price must be at least 20% below print price

The $12.99 ceiling is new. Amazon raised the top of the 70% band from $9.99 to $12.99 on 7 July 2026, the first increase since the tier was introduced. The $2.99 floor and the 35% tier were left alone. Existing books were not repriced automatically, so if you published before July and your book sits above $9.99 on the 35% option, you can now switch it to 70% provided it meets the other requirements. Any guide still telling you $9.99 is the hard ceiling was written before the change.

Pricing strategy for 2026:

• $0.99-$2.99: Good for reader magnets, short content, or building audience. Note that anything under $2.99 is stuck at 35%
• $2.99-$4.99: Sweet spot for fiction and shorter non-fiction
• $4.99-$9.99: Standard for full-length non-fiction and premium fiction
• $9.99-$12.99: Newly available at 70% since July 2026. Worth testing for long non-fiction, technical guides and box sets
• Above $12.99: Specialty and professional content, and it drops back to the 35% rate

Most authors price between $2.99 and $4.99 to stay competitive inside the 70% band. The wider band means the decision at the top end is now a positioning question rather than a royalty cliff: at $12.99 you still keep 70%, where a year ago you would have dropped to 35%.

KDP Select: Should You Enroll?

KDP Select is an optional program that requires 90-day exclusivity to Amazon. In exchange, you get:

• Kindle Unlimited: Readers with KU subscriptions can read your book free. You earn per page read
• Kindle Owners' Lending Library: Prime members can borrow your book
• Promotional tools: Free book promotions and Countdown deals
• Higher royalties: 70% in additional countries (Brazil, Japan, India, Mexico)

When to enroll: If you're focused on Amazon and want access to KU readers (which can significantly boost page reads). When to skip: If you want to distribute widely on Apple Books, Kobo, Google Play, etc.

Step 6: Upload and Preview Your Book

With your files ready, it's time to upload:

1. Log into your KDP dashboard
2. Click "Create New Title" and select Kindle eBook or Paperback
3. Enter all metadata (title, description, keywords, categories)
4. Upload your manuscript file
5. Upload your cover file
6. Use the Previewer to check formatting on different devices
7. Fix any issues flagged by the quality checker

Common upload issues:

• Image quality warnings: Ensure images are 300 DPI
• File too large: Compress images or reduce quality slightly
• Formatting breaks: Check the preview on Kindle, tablet, and phone views
• Font embedding: Stick to standard fonts to avoid display issues

Step 7: Publish and Go Live

Once you're satisfied with the preview:

1. Choose your territories (typically "All territories")
2. Set your pricing for each marketplace
3. Enroll in KDP Select if desired
4. Click "Publish Your Kindle eBook"

Your book enters Amazon's review queue. Most books go live within 24-72 hours. You'll receive an email confirmation when your book is available.

Note: First-time publishers may experience slightly longer review times. Books with controversial content or that trigger manual review can take up to 5 days.

Step 8: Launch Marketing Strategies

Publishing is just the beginning. Without marketing, your book will be invisible among millions of titles.

Pre-Launch (Before Publishing)

• Build an email list of interested readers
• Set up your Amazon Author Central profile
• Create social media buzz with cover reveals and excerpts
• Reach out to book bloggers and reviewers
• Prepare your launch team (people who'll buy and review on day one)

Launch Week

• Announce to your email list with a direct buy link
• Post on all social channels
• Ask friends and family to purchase and leave honest reviews
• Run a promotional price or free days if in KDP Select
• Monitor your sales rank and celebrate milestones

Ongoing Promotion

• Amazon Ads: Pay-per-click advertising directly on Amazon
• BookBub: Email promotion service (competitive but powerful)
• Social media: Consistent content about your book's topic
• More books: The best marketing is your next book. Series sell better
• Reviews: Encourage readers to leave reviews (critical for visibility)

Common Amazon KDP Mistakes to Avoid

• Skipping editing: Poor grammar and typos lead to bad reviews. Always edit professionally
• Amateur covers: Don't design your own unless you have real design skills
• Wrong categories: Placing your book in overly competitive categories buries it
• Ignoring keywords: Empty keyword fields mean lost discoverability
• Pricing too high: New authors without reviews struggle at premium prices
• No marketing plan: "If I publish it, they will come" is a myth
• Expecting overnight success: Most successful authors have multiple books and years of marketing

Frequently Asked Questions

Is it free to self-publish on Amazon KDP?

Yes, publishing on Amazon KDP is completely free. There are no setup fees, no listing fees, and no costs to make changes. Amazon makes money by taking a percentage of each sale (30% at the 70% royalty tier, 65% at the 35% tier).

How much money can you make self-publishing on Amazon?

The honest answer is that nobody can tell you, and any guide quoting you a typical KDP income is guessing. What is knowable is the per-sale side, because Amazon publishes it: on the 70% option a $4.99 ebook returns $3.49 and a $12.99 ebook returns $9.09, minus a delivery fee of $0.15 per megabyte of file size. Everything after that is copies sold, which turns on niche, cover, keywords, price, reviews and how many books you have out. We build books rather than sell them, so we hold no earnings data of our own and will not invent any. To model your own numbers, use our royalty calculator.

How long does it take for a book to go live on KDP?

Most ebooks go live within 24-72 hours after you click publish. Paperbacks may take slightly longer. During peak periods (like before Christmas) or if your book requires manual review, it could take up to 5 days.

Do I need an ISBN to publish on Amazon KDP?

For ebooks, no. Amazon assigns a free ASIN (Amazon Standard Identification Number) to every Kindle book. For paperbacks, you can use Amazon's free ISBN or purchase and provide your own. Note that Amazon's free ISBN limits distribution to Amazon only.

Can I publish AI-written books on Amazon KDP?

Yes. Amazon has required authors to disclose AI-generated text, images and translations during the publishing process since September 2023, but AI-assisted books are permitted. Read our full breakdown of the Amazon KDP AI disclosure policy for 2026 to understand exactly what you need to disclose. The key is ensuring your content provides genuine value and meets Amazon's quality guidelines. Books that are clearly low-effort AI spam get removed.

What is KDP Select and should I enroll?

KDP Select is an optional program requiring 90-day exclusivity to Amazon. You get access to Kindle Unlimited readers, promotional tools, and higher royalties in some countries. Enroll if you're focused on Amazon. Skip if you want to sell on other platforms like Apple Books or Kobo.

Can I update my book after publishing?

Yes. You can update your manuscript, cover, description, and keywords anytime. Changes typically take 24-48 hours to go live. However, significant content changes may trigger a new review.

How do I get reviews for my book?

Ask readers directly (a request at the end of your book helps), build a launch team of early readers, reach out to book bloggers in your genre, and use Amazon's "Request a Review" button in your sales dashboard. Never pay for reviews or incentivize them, which violates Amazon's terms.
