The Complete Beginners Guide to Self-publishing on Amazon KDP
KDP is free to use, but publishing decisions still affect royalty rate, discoverability and cost.
You’ve written a book. Maybe it took months. Maybe it took years. Either way, you’re now staring at the Amazon KDP dashboard wondering what on earth a BISAC code is, why “metadata” keeps appearing in every forum thread you visit, and whether you genuinely need to understand DPI before you can publish.
The good news: you don’t need to know everything. You need to know the right things, in the right order.
This is the guide to read before any other. It covers the complete self-publishing journey on Amazon Kindle Direct Publishing, from account setup to understanding why a book that’s already live might not be gaining traction. Every topic links out to a dedicated deep-dive article when you’re ready to go further. Bookmark it and work through it at your own pace.
What Amazon KDP Actually Is
Amazon KDP (Kindle Direct Publishing) is Amazon’s self-publishing platform. It lets authors publish eBooks, paperbacks, and hardcovers and sell them directly on Amazon, without a literary agent, a traditional publisher, or a minimum print run. When a reader buys your book, Amazon handles the transaction, prints the physical copy if required, manages fulfillment, and pays your royalties roughly 60 days after the end of the month in which the sale occurred.
There is no upfront cost to publish. Amazon earns its money through a percentage of each sale. This makes KDP a genuinely low-risk entry point for first-time and independent authors. For a detailed explanation of how the platform works mechanically, see our guide to what Amazon KDP is and how it works.
KDP vs traditional publishing
Traditional publishing involves submitting a manuscript to publishers, often through a literary agent, and then moving through acquisition, editing, production and distribution if a deal is made. Timelines and royalty structures vary substantially by publisher and contract.
With KDP, eligible eBooks can earn 35% or 70% royalties and standard print books use 50% or 60% royalty tiers before printing costs. Authors retain control over pricing, cover and publication decisions. Amazon says new titles generally take up to three business days to become live, with some formats and marketplaces taking longer; low-content books can take up to ten business days. The trade-off is that editing, cover design and marketing remain the author’s responsibility. For a fuller comparison, read our KDP vs traditional publishing guide.
Formats: eBook, Paperback, and Hardcover
KDP supports three publishing formats. The right choice depends on your genre, your audience’s reading habits, and your pricing strategy. Most authors publish in at least two formats simultaneously. For a full breakdown of the options, see our guide to what formats you can publish on KDP.
Kindle eBook
eBooks are delivered instantly to any device running the free Kindle app, smartphones, tablets, Kindle e-readers, and computers. There are no printing costs, which means lower overheads and higher royalties. Most new KDP authors begin here. eBooks work particularly well for fiction, business books, and non-fiction titles that don’t rely on complex or heavily illustrated layouts.
Paperback
KDP’s paperback option uses print-on-demand (POD) technology. A copy is printed only when a reader orders it, there is no minimum print run, no stock to hold, and no upfront printing cost. Quality is consistently good, though it varies slightly between Amazon’s printing facilities. For a detailed look at how this works, see our article on KDP print-on-demand explained.
Hardcover
KDP added hardcover publishing in 2021. The process mirrors paperback publishing but hardcovers support higher price points and higher printing costs. They suit gift books, illustrated reference titles, and non-fiction where perceived authority matters. Not all titles are eligible, KDP flags this during setup. For help choosing between the two print formats, read our guide to KDP hardcover vs paperback.
| Format | Royalty | Price for max rate | Best for |
|---|---|---|---|
| Kindle eBook | 70% (minus delivery fee) | $2.99–$12.99 | Fiction, narrative non-fiction, business |
| Kindle eBook | 35% | Below $2.99 / above $12.99 | Permafree lead magnets |
| Paperback | 60% minus print cost | $9.99 or above (US) | All genres; non-fiction particularly |
| Paperback | 50% minus print cost | $9.98 or below (US) | Lower-priced print titles |
| Hardcover | 60% minus print cost | $9.99 or above (US) | Gift books, illustrated titles, prestige non-fiction |
Setting Up Your KDP Account
Go to kdp.amazon.com and sign in with your existing Amazon account or create a new one. Before you can receive royalties, you need to complete your tax information, US authors submit a W-9, non-US authors complete a W-8BEN. Amazon is legally required to collect this before making payments, and the form takes around five minutes. You’ll also need to add a bank account for royalty transfers.
For a step-by-step walkthrough of the full setup, including how to configure your payment settings and tax interview, see our guide to how to set up your KDP account. For non-UK and non-US authors, our guide to KDP for non-US authors covers territory-specific considerations including withholding tax treaties.
Author Central
Once your KDP account is live, set up an author profile at Amazon Author Central. This is a separate system from your KDP dashboard, it’s your public-facing author page, where you manage your biography, author photo, and book list. Readers who click your name on any Amazon product page land here. It’s free, takes 20 minutes to complete properly, and has a measurable effect on how credible and professional your author presence appears. Note that the Author Central interface was unified under the author.amazon.com domain in late 2024; the older authorcentral.amazon.com URL still redirects but the canonical URL is now the shorter one. For full instructions, see our article on how to link your KDP and Author Central accounts.
Preparing Your Manuscript
KDP accepts ebook manuscripts in three formats: EPUB, DOCX (Word), and KPF (the proprietary file produced by Amazon’s free Kindle Create tool). For most authors, uploading a Word document is the most straightforward approach, KDP’s conversion engine handles the transformation to Kindle’s KFX delivery format. Print books are uploaded as PDF, which gives you the most control over the final output. KDP retired its older MOBI format in stages between August 2021 and March 2025, and HTML and RTF are no longer accepted as ebook input formats.
Before you upload, your manuscript must meet KDP’s formatting requirements. The most common issues that cause file rejection or poor rendering are covered in full in our KDP manuscript formatting requirements checklist. The most frequent culprits are:
- Incorrect margins, KDP has minimum margin requirements that vary by format and page count
- Images below 300 DPI in print files, which print poorly and trigger quality warnings
- Headers and footers that conflict with KDP’s automatic page number insertion
- Embedded fonts not licensed for embedding
- Inconsistent heading styles that break automatic table of contents generation
Amazon’s free Kindle Create tool handles most of these issues automatically for straightforward fiction or basic non-fiction. For guides to formatting specific formats, see our articles on how to format a KDP eBook and how to format a KDP paperback. For details of what needs to go at the front and back of your book, read our guide to front and back matter for KDP books.
Is your manuscript ready to publish?
Reader reviews are permanent, and errors discovered after publication are both costly to fix and damaging to your reputation. Before your manuscript goes anywhere near KDP, it needs a professional check. Vappingo’s book manuscript proofreading service pairs you with experienced editors who understand the specific demands of self-published books, catching everything from typos and punctuation errors to inconsistencies in character names, timeline, and formatting. Get it right before it goes live.
Your Book Cover: The Most Important Marketing Asset You Have
Amazon is a visual marketplace. Your cover competes in search results alongside titles produced by professional art directors at major publishing houses. A poor cover signals a poor book, readers make visual judgements in under a second, and no amount of great writing overcomes a cover that looks amateurish in a thumbnail.
KDP accepts ebook cover files as JPEG or TIFF, with minimum dimensions of 625 pixels wide by 1,000 pixels tall and recommended dimensions of 1,600 pixels wide by 2,560 pixels tall, the standard 1.6:1 portrait aspect ratio that scales cleanly across every Amazon display context. The maximum allowed is 10,000 × 10,000 pixels. For paperback and hardcover, you need a full-wrap PDF cover file in CMYK that includes front, spine, and back. For guidance on what works and why, read our articles on what makes a good book cover for Amazon and how to design a book cover for KDP without design skills. If you’re working to a budget, our guide to hiring a book cover designer on a budget covers your options realistically.
When briefing any designer, study the top 20 bestsellers in your specific category on Amazon first. Your cover needs to fit the visual conventions of your genre while standing out within it. A cover that looks like it belongs to a different genre actively suppresses your conversion rate.
Royalties and Pricing
KDP uses different royalty formulas by format, marketplace and list price. For eBooks, the familiar 35% and 70% options remain, but Amazon.com changed the qualifying 70% price band in July 2026: it is now $2.99 to $12.99, subject to the other 70% conditions. At the 70% option Amazon also deducts delivery costs, while the 35% calculation does not use the same delivery-cost deduction.
eBook royalties
Do not choose price solely to reach 70%. A higher or lower list price can make more sense if it improves conversion, positions the book correctly or produces more dollars of royalty per buyer. The right comparison is profit per visitor and total demand, not the percentage in isolation.
Paperback and hardcover royalties
Standard print distribution now uses 50% or 60% of list price depending on the marketplace-specific price threshold, and printing cost is then deducted. Expanded Distribution uses a 40% rate before printing cost. Because trim size, page count, ink and marketplace affect printing cost, use KDP’s calculator for the exact book rather than an old flat 60% assumption.
KDP Select vs Wide Publishing
This is one of the most consequential strategic decisions a KDP author makes. Our dedicated article on KDP Select vs wide publishing covers every angle, but here is the core trade-off.
Enrolling in KDP Select means your eBook is exclusive to Amazon for rolling 90-day periods. In return, your book is included in Kindle Unlimited, Amazon’s subscription service, where you earn a royalty based on pages read from the KDP Select Global Fund. You also gain access to Kindle Countdown Deals and Free Book Promotions. For a detailed guide to running promotions effectively, see our articles on how to use Kindle Countdown Deals and how to run a KDP free promotion effectively.
Wide publishing means distributing your eBook across multiple platforms simultaneously, Apple Books, Kobo, Google Play, and others, using an aggregator like Draft2Digital or uploading to each platform directly. This removes KU income but opens significant additional markets. For a full platform comparison, read our guide to KDP vs IngramSpark vs Draft2Digital.
Keywords: How Readers Find Your Book
Amazon search uses book metadata and shopper behavior to decide which products are relevant to a query. KDP gives publishers seven backend keyword fields, and Amazon recommends short phrases that accurately describe the book rather than vague single words, repeated metadata or misleading terms. The KDP interface enforces its current field limits, so use the live title setup screen rather than relying on an old fixed-character total from a blog post.
Start with phrases that reflect real buyer searches and fit the book precisely. Amazon autocomplete can provide useful language clues, then competitor and market research can help decide which phrases deserve a backend slot. For detailed guidance, see our Amazon KDP keyword research guide and guide to choosing seven backend keywords.
KDP Rank Fuel can carry that research into the same book’s listing workflow, including keyword research, category research, listing generation, listing auditing and optimization, so evidence does not have to be recreated in separate tools.
Categories and BISAC Codes
KDP currently lets publishers choose up to three categories during title setup. Available choices can differ by marketplace and format, and the categories selected in KDP are not identical to every Best Seller Rank category Amazon may display on a live detail page. Amazon also says it may change a book’s categories to maintain a positive customer experience, so category selection should be treated as accurate classification rather than a permanent promise of a particular bestseller list.
Choose the most specific categories that genuinely fit the book and compare the live category structure before publication. Avoid old advice about emailing KDP support to force extra browse-node placements. For the current mechanics, see our guide to how many KDP categories you can choose and our category-selection guide.
Your Book Description: The Hardest 400 Words You’ll Write
After your cover, your book description is your most important conversion asset. A reader who clicks through to your Amazon page has already shown interest, the description’s job is to turn that interest into a purchase. Amazon allows up to 4,000 characters and supports a limited set of HTML tags for formatting. The complete strategy for writing a high-converting description is in our guide to how to write an Amazon book description that actually sells.
For genre-specific guidance, we have dedicated articles on writing descriptions for fiction, non-fiction, romance, thrillers and mystery, and self-help books. If your description is already live and not converting, our article on how to rewrite a failing book description walks through a systematic diagnostic process.
The four principles that apply regardless of genre:
- Lead with your strongest hook. The first two lines appear above the “Read more” fold on mobile. If they don’t compel the reader to continue, nothing below them matters.
- Establish what’s at stake. What does your protagonist stand to lose? What specific problem does your non-fiction book solve, and for exactly whom?
- Build urgency. Fiction descriptions typically close with a cliffhanger question. Non-fiction descriptions close with a clear statement of the transformation the reader will experience.
- End with a direct call to action. “Scroll up and download your copy today” is direct, functional, and consistently effective across categories.
The Publishing Process: Step by Step
Once your manuscript, cover, and metadata are ready, the publishing process itself is straightforward. For a complete step-by-step walkthrough of each screen in the KDP dashboard, see our KDP dashboard walkthrough. Here is the sequence at a high level:
Log in to your KDP account and click “Create a New Title”. Select your format, eBook, Paperback, or Hardcover. If you want all three, you create a separate entry for each, which you then link together as a series if applicable.
Title, subtitle, series information, author name, description, keywords, and categories. This metadata determines discoverability. For a detailed guide to uploading your manuscript correctly, see how to upload your manuscript to KDP.
Upload your manuscript and cover files. KDP generates a preview, use it. Check every chapter and every page on both the eBook and print previewer. What you see here is what your readers will see. For guidance on what to look for, see our article on how to preview your book before publishing.
Review your royalty estimate at your chosen price in each territory before proceeding. Click publish and wait for Amazon’s review, typically 24 to 72 hours. For a full explanation of what happens next, see our article on what happens after you hit publish on KDP.
What to Do in the First 30 Days After Publishing
A new book’s first weeks are useful because they produce the first real evidence about discoverability, clicks, sales, ads and reader response. Amazon does not publish a guaranteed “new-book boost” that authors can model as a fixed ranking window, so launch planning should focus on controllable inputs: accurate metadata, a competitive cover, clear product-page copy, realistic pricing, legitimate early-reader outreach and advertising that generates interpretable search-term data.
Get your first reviews
Reviews can reduce uncertainty for shoppers, especially for an unknown author, but they are only one part of conversion alongside the cover, title, price, description and the match between the book and the search that produced the visit. Build reviews through legitimate, terms-compliant methods rather than treating a review count as an algorithmic threshold. See our guide to getting reviews as a new author and our article on using ARC copies on Amazon.
Start your Amazon advertising
Amazon Advertising, accessible through the Amazon Ads console, is the most direct way to drive targeted traffic to your book page. Even a small daily budget generates data about which search terms are converting, which you can use to refine your organic keyword strategy. Our beginner’s guide to Amazon Ads for authors covers setup, targeting, and bidding strategy from scratch.
If Your Book Isn’t Selling: What to Check
A book that isn’t selling is not necessarily a bad book. More often it’s a discoverability or conversion problem, something in the metadata, cover, description, or pricing is creating friction. Our dedicated guide on why your book isn’t selling on Amazon and how to fix it walks through a full diagnostic. Start with this checklist:
- Cover: Does it look competitive against the top 20 books in your specific category? Get honest feedback from readers in your genre, not friends and family.
- Keywords: Have you used all seven keyword fields? Are you targeting search phrases readers actually use, or generic single words with no specificity?
- Categories: Are you using all three category slots in each format you publish in? Are you in appropriate categories with realistic competition levels rather than ones too broad to rank in?
- Description: Does your opening sentence compel a reader to continue? Does the description close with a call to action? Is it using HTML formatting for readability?
- Price: Are you priced competitively for your category, format, and page count? Read our article on how your book’s price affects sales on Amazon.
- Reviews: Do you have enough reviews for a reader to feel confident buying from an author they don’t yet know?
- Amazon Best Seller Rank: Understanding your BSR and what it means is covered in our guide to what the Amazon Best Seller Rank is and how to improve it.
Tools That Make KDP Publishing Easier
The KDP dashboard covers the basics, but authors who treat this as a serious publishing endeavour use additional tools to work more efficiently and make better-informed decisions. Our full roundup of the best tools for Amazon KDP authors covers the complete landscape, including free and paid options across every stage of the publishing process.
Carry the research into the book you are publishing
KDP Rank Fuel connects keyword, competitor and category research with listing creation, auditing and optimization, so evidence gathered for a book can feed the next publishing decision instead of being recreated from scratch. The platform also includes advertising workflows for authors who want to turn that research into campaign planning.
Beyond KDP Rank Fuel, the tools most consistently useful across the publishing process are listed below. The right choice depends on which stage of publishing needs help.
- Amazon Author Central: Free. Manages your public author profile and links all your titles. Set it up before your first book goes live.
- Kindle Create: Free. Amazon’s own formatting tool. Sufficient for straightforward fiction and basic non-fiction.
- Atticus: Paid. Cross-platform book formatting for both eBook and print output. Produces professional results without requiring design skills.
- Draft2Digital: Free to use (percentage of sales). Handles wide distribution to Apple Books, Kobo, Barnes & Noble, and others from a single upload.
- BookBub: A major promotional platform for discounted and free eBook promotions. Featured Deals are selective, so treat them as one option within a wider launch and promotion plan. Our guide to how to use BookBub to boost Amazon sales covers the strategy.
Errors discovered after publication are permanent.
The most effective investment you can make in your book’s long-term performance is publishing it in the best possible condition. Vappingo’s manuscript editing service and book manuscript proofreading service are both designed for authors preparing work for self-publication, whether you need a full developmental edit, a copy edit for clarity and consistency, or a final proofread before you upload. Your readers will notice the difference. One-star reviews citing errors are the most preventable problem in self-publishing.

Current KDP Rules to Recheck
Amazon changes KDP pricing, metadata and distribution rules, so this guide has been checked against current KDP Help rather than relying on older self-publishing conventions. Recheck the relevant help page before making a decision that affects a live title. The most useful official references for the topics covered here are:
- eBook royalty options and list-price requirements
- print royalty and printing-cost calculations
- book details, keywords and categories
- book description and formatting rules
Where a decision affects a live book, check the help page again before publishing. Marketplace thresholds and eligibility details are more important than memorizing an old rule from a blog post.
Frequently Asked Questions
Do KDP rules change often enough to recheck before publishing?
Yes. Royalty thresholds, file rules, metadata guidance and feature eligibility do change. Use current KDP Help for the final decision, especially when pricing or changing metadata on a live book.
Should I optimize for Amazon or for readers first?
Both matter, but they do different jobs. Metadata helps the right shoppers discover and understand the book, while reader-facing copy has to make a credible case for the click and purchase. Do not damage clarity by forcing keywords into persuasive copy.
How should I decide what to change first on an underperforming book?
Start with evidence. Check whether the book is being found for relevant searches, whether the cover and title earn the click, whether the description communicates value, and whether price and reviews create a competitive offer. KDP Rank Fuel is designed to connect those research and listing decisions rather than treating them as unrelated tools.
Can I change metadata after publication?
Many fields can be updated, but some book details are restricted after publication and changes can take time to appear. Make deliberate changes, keep a record of what changed and avoid judging the result before the update has propagated.
When should I get professional editorial help?
If the manuscript, description or publishing copy is difficult to assess objectively, a qualified editor can identify clarity, structure and language problems before marketing spend amplifies them. Vappingo offers book editing and professional proofreading for authors who want a human editorial review.
