If you've searched Amazon how to publish a book, you're likely staring at a manuscript—or an idea—and trying to figure out whether KDP is as straightforward as it's advertised. The short answer: the platform itself is accessible, but the decisions around formatting, metadata, ISBNs, and pricing require more precision than the "upload and go" framing suggests. This guide covers every meaningful step, the actual royalty math, and the production choices that determine whether your book competes or gets buried.
Kindle Direct Publishing (KDP) is Amazon's self-publishing arm, handling both digital eBooks and print-on-demand (POD) paperbacks and hardcovers. It's the dominant self-publishing platform in the US market. According to Publishers Weekly, Amazon controls the vast majority of the self-published eBook market in the United States, making KDP the logical starting point for most independent authors. But knowing how the platform works—and what separates books that find readers from those that don't—is where genuine preparation matters.
KDP is Amazon's free self-publishing platform where authors upload manuscript files and cover designs, set metadata and pricing, and receive royalties on each sale. There are no listing fees; Amazon recoups its costs as a percentage of each sale. You retain copyright to your work throughout.
KDP handles two distinct product types under one dashboard:
KDP is separate from Amazon Publishing, which is Amazon's traditional publishing imprint (with imprints like Thomas & Mercer and Montlake). Amazon Publishing acquires manuscripts, pays advances, and handles production—authors do not self-submit there the same way. If you're uploading your own book, you're using KDP.
Authors can enroll eBooks in KDP Select, which provides access to Kindle Unlimited (KU) and Kindle Owners' Lending Library in exchange for 90-day exclusivity to Amazon. KU pays a per-page-read rate drawn from a global pool—historically around $0.004–$0.005 per page read, though the exact rate fluctuates monthly. Authors not in KDP Select can distribute eBooks through aggregators like Draft2Digital or Smashwords to reach Apple Books, Kobo, Barnes & Noble, and other retailers simultaneously.
Publishing on KDP involves six discrete stages. Each one has decisions that affect discoverability, earnings, and long-term sales—so it's worth understanding what you're choosing at each step.
Go to kdp.amazon.com and sign in with an existing Amazon account or create a new one. You'll need to complete your tax information (W-9 for US authors, W-8BEN for international) and banking details before any royalties are disbursed. Amazon pays approximately 60 days after the end of the month in which sales occur, once you reach the payment threshold (typically $100 by check, $10 by direct deposit).
Metadata is not an afterthought—it is how Amazon's algorithm decides who sees your book. Fill in:
For KDP eBooks, Amazon assigns a proprietary ASIN (Amazon Standard Identification Number) at no cost—no ISBN is required for the Kindle edition. For print books, you have two options:
Authors serious about library sales or wanting their book listed in the Library of Congress catalog should secure a Preassigned Control Number (PCN) from the Library of Congress before the book is printed—this requires a publisher account and your own ISBN. Libraries rely on records from the Library of Congress and services like NetGalley for acquisition decisions, so this infrastructure matters if the library market is part of your strategy.
KDP accepts several file formats for interior content:
| File Type | Best For | Notes |
|---|---|---|
| DOCX (Microsoft Word) | eBook, simple print layouts | KDP converts automatically; complex formatting may shift |
| EPUB | eBook | Most control over digital formatting; preferred by experienced authors |
| Print books | Required for print; must match exact trim-size and bleed specs | |
| KPF (Kindle Create) | eBook | Amazon's own tool; good for beginners, limited customization |
Cover files must meet specific resolution requirements (at least 300 DPI for print; at least 1000px on the shortest side for eBook). KDP offers a free Cover Creator tool, but covers built with it are instantly recognizable as amateur productions. A professionally designed cover is one of the highest-ROI investments a self-published author can make—readers absolutely judge books by their covers, and the thumbnail on Amazon is your primary advertisement.
KDP's royalty tiers create a natural pricing constraint for eBooks: to earn 70%, your list price must fall between $2.99 and $9.99. Books outside this range earn 35%. For most nonfiction, a $9.99 eBook price is defensible and maximizes revenue per unit at the 70% tier. For fiction, genre conventions often push prices lower, especially for debut authors building an audience.
For print, KDP calculates a minimum price based on the per-page printing cost. The printing cost for a black-and-white 6×9 paperback is roughly $0.85 fixed + $0.012 per page for the US market. A 300-page paperback therefore costs approximately $4.45 to print; to earn any royalty, you must price above that threshold. KDP provides a real-time royalty calculator in the pricing dashboard.
After submitting, KDP reviews the book for content policy compliance. This typically takes 24–72 hours. Once approved, the listing goes live on Amazon.com and other Amazon marketplaces you've selected. Print copies become available for order immediately through POD; no inventory risk, no warehouse fees.
Post-publication, authors can track sales through the KDP dashboard. Sales rank data on the book's Amazon listing is updated hourly. For broader market context, NPD BookScan tracks print sales across major US retail channels—but access to BookScan data requires a subscription or publisher account. KDP's dashboard does not integrate BookScan; authors see only their own KDP sales.
KDP charges no upfront publishing fees. The real costs of self-publishing on Amazon are the production costs you incur before uploading: editing, cover design, formatting, and optionally, marketing. These are optional but significantly affect commercial outcomes.
Here is a realistic cost breakdown for a professionally produced self-published book:
| Service | DIY Option | Professional Range (Market) |
|---|---|---|
| Developmental Editing | Beta readers / writing groups | $1,000–$5,000+ |
| Copyediting / Proofreading | Grammar tools (Grammarly, ProWritingAid) | $300–$1,500 |
| Cover Design | KDP Cover Creator (free) | $300–$1,500 |
| Interior Formatting | Kindle Create / Atticus (free–$147) | $150–$500 |
| ISBN (own imprint) | Free KDP ISBN | $125–$295 (Bowker) |
| Ghostwriting (if needed) | N/A | Custom quote (book a call) |
| Total (realistic professional) | ~$0 platform fees | $2,000–$10,000+ production |
If writing the manuscript itself is the barrier—whether due to time, expertise, or the gap between what you know and what you can articulate on the page—professional ghostwriting handles the content before the KDP steps even begin. Dictate's ghostwriting services are built specifically for this: you provide the knowledge, voice, and direction; a professional writer produces the manuscript. For a broader look at all the paths and associated costs of bringing a book to market, see How to Publish a Book: Paths, Costs & Real Steps.
KDP eBook royalties are 35% or 70% of the list price, depending on the pricing tier. Print royalties are 60% of the list price minus the printing cost. Authors receive these royalties for each sale; there are no ongoing fees, no annual charges, and no minimum sales requirements.
A few concrete examples of what this looks like in practice:
These numbers clarify why many self-published authors focus on eBooks for margin and use print as a credibility vehicle rather than a primary revenue source—though for nonfiction, print often outsells digital.
According to the Authors Guild's author income surveys, median author income from writing remains modest, and self-published authors' earnings vary enormously based on genre, catalog size, marketing investment, and audience development. Authors with multiple books in a series, an email list, and active marketing consistently outperform those who upload once and wait.

The mechanical steps of KDP are genuinely learnable in an afternoon. The difference between a book that sells and one that stagnates comes down to four factors that have nothing to do with the upload process itself.
Readers leave reviews, and reviews compound. A book with structural problems—weak argument flow in nonfiction, pacing issues in fiction, unclear prose throughout—will accumulate negative feedback that suppresses the algorithm over time. No amount of metadata optimization rescues a book that doesn't deliver on its premise. Professional editing, and for many authors professional writing assistance, is not optional if commercial results matter.
At thumbnail size, your cover competes visually against every other book in its category. Genre-appropriate design conventions are not arbitrary; they are reader signals. A thriller cover that looks like a self-help book loses sales immediately. Study the top 20 covers in your target category before commissioning a designer.
BISAC category selection and KDP keyword phrases determine which browse paths lead to your book. Authors who research keyword demand—using tools like Publisher Rocket or simply analyzing Amazon's own autocomplete suggestions—consistently outperform those who guess. Two of your seven keyword slots should reflect exactly how readers search, not industry terminology.
Amazon's algorithm weights sales velocity in the first 30–90 days heavily. A coordinated launch—with an advance reader copy (ARC) program to generate reviews before or at launch, email list activation, and potentially a limited-time price promotion—outperforms a quiet upload. Services like NetGalley facilitate ARC distribution to verified readers and librarians, which is particularly valuable for nonfiction seeking early credibility signals.
For authors who want to understand the full production cost picture before making decisions, How Much Will It Cost to Publish a Book: Fees Explained provides a comprehensive fee-by-fee breakdown across publishing paths.
Publishing on KDP itself is free—Amazon charges no listing or setup fees. The costs authors incur are production costs: editing, cover design, and formatting, which can range from near zero (fully DIY) to $5,000–$10,000 or more for professional production. KDP recoups its platform costs as a percentage of each sale rather than upfront fees.
At a 70% royalty on a $9.99 eBook, you earn roughly $6.99 per sale. To reach $100,000, you'd need approximately 14,300 sales. At a 35% royalty on a $4.99 eBook (~$1.75/sale), you'd need about 57,000 sales. Most authors who reach six-figure income from self-publishing do so through multiple titles, series momentum, and combining eBook, print, and audiobook formats rather than a single title.
The technical barrier to publishing on KDP is low—any author can upload a manuscript and cover file and have a live listing within a few days. The harder challenge is producing a book that competes quality-wise in your genre and then marketing it effectively. Amazon's content guidelines are the only gate; there is no editorial submission or acceptance process.
Per-sale earnings depend on format and price. A $9.99 eBook at the 70% tier earns approximately $6.99. A $14.99 paperback on a 300-page book earns approximately $4.50–$5.00 after printing costs. KDP Unlimited pays per page read, typically in the range of fractions of a cent per page—so a 300-page book fully read earns roughly $1.20–$1.50 from a KU reader at historical rates. Actual income is a function of how many copies sell, not just per-unit math.
Yes—you need a completed, formatted manuscript before uploading to KDP, but there's no requirement that you wrote it personally. Many professionals and executives work with ghostwriters to develop their manuscript before self-publishing. Dictate's ghostwriting services handle the writing process from concept through final manuscript, so the KDP steps become straightforward once the content exists.
KDP makes distribution to Amazon's global audience genuinely accessible. What it doesn't do is write your book, edit it, design the cover, or market it. For authors who have expertise, a story, or authority to share—but not the time or writing background to translate that into a publishable manuscript—working with a professional is the most direct path from idea to published author.
Dictate's ghostwriting services are designed exactly for this: you bring your knowledge and voice, and a professional writer builds the book. Custom pricing is available for every project scope; payment plans and financing are offered, and the investment is typically a fraction of traditional ghostwriting fees.
