Amazon self-publishing works through a free platform called Kindle Direct Publishing (KDP). You upload your manuscript, set your price, and Amazon handles printing, distribution, and payment. There are no upfront costs, no inventory to manage, and your book can be live on Amazon within 72 hours.
Here is how the entire system works — from account creation to royalty deposits hitting your bank account.
What is Amazon KDP?
Kindle Direct Publishing is Amazon’s self-publishing platform. It launched in 2007 alongside the first Kindle e-reader and has since grown into the dominant force in independent publishing. Amazon controls roughly 70-80% of the global ebook market, making KDP the single most important platform for self-published authors.
Through KDP, you can publish three formats:
- Kindle ebooks — Digital books delivered instantly to any Kindle device or app
- Paperback books — Physical books printed on demand when a customer orders
- Hardcover books — Premium physical editions, also printed on demand
The platform is completely free to use. Amazon makes money by taking a percentage of each sale rather than charging you to publish. This is the opposite of vanity presses that charge thousands upfront — with KDP, you pay nothing until you earn something.
Over 1.4 million books are self-published through KDP every year, and Amazon pays over $520 million in annual royalties to self-published authors.
How the publishing process works
The KDP publishing workflow has three phases: setup, upload, and pricing. The entire process takes 30-60 minutes once your manuscript and cover are ready.
1. Create your KDP account
Go to kdp.amazon.com and sign in with any Amazon account. During setup, you’ll complete a tax interview (W-9 for US authors, W-8BEN for international authors) and add your bank account for royalty payments. The account is free and takes about 10 minutes.
2. Enter your book details
For each book you publish, KDP asks for:
- Title and subtitle
- Author name (real name or pen name)
- Description — Your book’s sales copy, up to 4,000 characters
- Keywords — Seven keyword phrases that help readers find your book in Amazon search
- Categories — Two browsable categories where your book appears
Keywords and categories are critical for discoverability. The right choices put your book in front of readers actively searching for your topic. For a deeper look at keyword strategy, see our guide to Amazon keywords for books.
3. Upload your manuscript and cover
KDP accepts manuscripts in DOCX, EPUB, or KPF format for ebooks, and PDF or DOCX for print books. You also upload a book cover — either one you designed or had designed professionally.
Amazon provides a Cover Creator tool for basic designs, but most successful authors invest in a professional cover. Your cover is the single biggest factor in whether a reader clicks on your book or scrolls past it.
After uploading, the KDP Previewer shows you exactly how your book will look on different devices and in print. For formatting specifics, check out our guide on how to format a book for Kindle.
4. Set your price and publish
Choose your list price, select which Amazon marketplaces to distribute to (US, UK, Germany, Japan, and more), and hit publish. Amazon reviews your book — typically within 24-72 hours — and then it goes live on the Kindle Store and Amazon marketplace.
That’s it. No query letters, no agents, no waiting months for a response. Your book is available to hundreds of millions of Amazon customers worldwide.
How Amazon KDP royalties work
KDP offers different royalty structures depending on format and pricing. Understanding these is essential before setting your book’s price.
Ebook royalties
You choose between two options for each ebook:
| Royalty Option | Price Range | Delivery Cost | Best For |
|---|---|---|---|
| 70% royalty | $2.99–$9.99 | $0.15/MB deducted | Most ebooks |
| 35% royalty | $0.99–$200 | None | Low-price or high-price books |
The 70% option has a delivery fee based on file size, but for most text-only books this is pennies. A $4.99 ebook at the 70% rate earns you roughly $3.44 per sale. Compare that to traditional publishing, where authors typically earn 10-15% of the cover price.
Print book royalties
For paperbacks and hardcovers, your royalty is calculated as:
(Royalty rate x list price) – printing cost = your royalty
As of 2025, paperback royalty rates are 60% for books priced at $9.99 or above, and 50% for books below that threshold. Printing costs depend on page count, ink type (black or color), and trim size.
For example, a 200-page paperback priced at $16.99 earns roughly $6.79 per sale after printing costs.
When you get paid
KDP pays royalties monthly, approximately 60 days after the end of the month in which sales were made. So books sold in January get paid around the end of March. Payments go directly to your bank account via electronic transfer.
KDP Select and Kindle Unlimited
When you publish an ebook, Amazon offers an optional program called KDP Select. Enrolling gives your book access to Kindle Unlimited (KU), Amazon’s subscription reading service with millions of subscribers.
Here is the tradeoff:
- What you get: Your ebook is available in Kindle Unlimited, where you earn based on pages read. You also get access to promotional tools like Kindle Countdown Deals and Free Book promotions.
- What you give up: Ebook exclusivity. While enrolled in KDP Select (90-day renewable terms), you cannot sell your ebook on any other platform — not Apple Books, Kobo, Google Play, or your own website.
The KDP Select Global Fund paid out $61.7 million to authors in February 2026 alone. For many authors, especially in fiction genres like romance and thriller, KU page reads earn more than direct sales.
Whether to go exclusive with KDP Select or sell “wide” across multiple platforms is one of the biggest strategic decisions self-published authors face. For a comparison of your distribution options, see our guide to the best self-publishing platforms.
What you need before publishing
Before you start the KDP upload process, you need three things ready:
A finished, edited manuscript. This is the biggest bottleneck for most aspiring authors. Writing a full book takes time — or it used to.
Our Pick — Chapter
Chapter.pub helps you go from idea to finished manuscript faster than writing from scratch. It builds structured outlines, writes full chapters in your voice, and handles the heavy lifting so you can focus on your expertise and story. Over 2,147 authors have used it to create more than 5,000 books.
Best for: Nonfiction authors who want a complete, publishable draft in days instead of months Pricing: $97 one-time Why we built it: The #1 reason people never self-publish on Amazon is they never finish writing. Chapter fixes that.
A professional book cover. Your cover needs to look good as a thumbnail in Amazon search results. Budget $100-500 for a quality cover from a freelance designer on platforms like 99designs or Reedsy. Do not use a homemade cover — readers judge books by their covers immediately and without mercy.
A compelling book description. Your Amazon book description is your sales page. Write it like ad copy: lead with the hook, highlight what the reader will gain, and end with a call to action. You get 4,000 characters — use them wisely.
The complete timeline
Here is a realistic timeline from start to finish for how Amazon self-publishing works:
| Stage | Timeline |
|---|---|
| Write your manuscript | 2-12 weeks (or days with Chapter.pub) |
| Edit and proofread | 1-4 weeks |
| Design your cover | 3-7 days |
| Format for KDP | 1-3 days |
| Upload and publish on KDP | 30-60 minutes |
| Amazon review and approval | 24-72 hours |
| Book live on Amazon | Within 72 hours of upload |
The writing phase is the longest part of the process by far. Everything after the manuscript is finished moves quickly.
How much money can you make?
Author earnings vary wildly. The honest numbers:
- Amazon has paid out more than $520 million in annual royalties to KDP authors
- Over 2,000 self-published authors have earned more than $100,000 in KDP royalties
- The median self-published author income is roughly $13,500 per year, according to the Alliance of Independent Authors
- Most first-time authors earn modest amounts — the real money comes from building a catalog of multiple books
The authors who earn consistently treat self-publishing as a business. They write in series, invest in covers and editing, run Amazon ads, build email lists, and publish regularly.
Common mistakes to avoid
- Publishing before the book is ready. A poorly edited book earns bad reviews fast. One-star reviews tank your visibility in Amazon’s algorithm and are nearly impossible to overcome.
- Ignoring your book description and keywords. A great book with a bad description and wrong keywords is invisible. Spend real time on your Amazon keywords and category selection.
- Pricing too high or too low. For ebooks, the $2.99-$9.99 sweet spot gets you the 70% royalty rate. Pricing a nonfiction ebook at $0.99 signals low quality. Pricing it at $14.99 means you only earn 35%.
- Skipping KDP Select research. Going exclusive with KDP Select is not automatically the right move. Research whether your genre thrives in Kindle Unlimited before committing to a 90-day exclusivity window.
- Expecting passive income from one book. Self-publishing works best as a long-term strategy. Authors who publish multiple books and market them actively consistently outperform those who publish once and wait.
FAQ
Is Amazon self-publishing really free?
Yes. KDP charges nothing to create an account, upload your book, or list it for sale. Amazon makes money by taking a percentage of each sale — you earn the rest as royalties. The only costs are what you choose to invest in editing, cover design, and marketing.
Can you make a living self-publishing on Amazon?
Some authors do. Over 2,000 KDP authors have earned more than $100,000, and many full-time indie authors earn six figures annually. But most first-time authors earn modest amounts. Consistent income typically requires multiple books, smart marketing, and treating publishing as a business.
How long does it take to publish a book on Amazon?
Once your manuscript and cover are ready, the KDP upload process takes about 30-60 minutes. Amazon reviews new titles within 24-72 hours. After approval, your book is live and available for purchase globally.
Do you need an ISBN to publish on Amazon?
No. Amazon provides a free ASIN (Amazon Standard Identification Number) for every Kindle ebook. For print books, KDP offers a free ISBN — though you can also use your own purchased ISBN if you prefer. Using KDP’s free ISBN means Amazon is listed as the publisher of record.
What is the difference between KDP and KDP Select?
KDP is the publishing platform itself — every self-published book on Amazon goes through KDP. KDP Select is an optional enrollment program that gives your ebook access to Kindle Unlimited in exchange for 90-day ebook exclusivity on Amazon. You can publish on KDP without ever enrolling in KDP Select.
