Kindle Direct Publishing โ KDP for short โ is the self-service arm of Amazon's bookstore. You upload a manuscript and a cover, set a price, and within a few days your title sells next to traditionally published books, with no gatekeeper, no upfront fee, and no print run to finance.
That openness is the whole appeal, and it is also why the dashboard can feel intimidating the first time. There are three formats, two royalty plans, a content-policy review, and an AI-disclosure question that did not exist a few years ago. None of it is hard once you have seen it laid out in order.
This guide walks the full path in the sequence you'll actually meet it: understand the platform, open the account, choose a format, do the royalty math, decide between exclusivity and going wide, sidestep the handful of issues that get books rejected, and โ if you want to move faster โ fold an AI writing workflow into the front end of the process.
What Kindle Direct Publishing is
KDP is Amazon's print-on-demand and ebook distribution platform. "Print-on-demand" means there is no inventory: when a reader buys your paperback, Amazon prints and ships that single copy and pays you the margin. Your ebook is delivered instantly to a Kindle app or device. You never touch a box of books unless you order author copies yourself.
It is distinct from a publisher. KDP does not edit, design, or market your book for you โ it gives you the storefront and the printing-and-payments machinery, and the editorial work stays yours. That trade is what makes 70% royalties and same-week publishing possible.
How KDP works, start to finish
The platform follows the same five beats for every book, whether it's a 300-page novel or a 24-page activity book. Knowing the shape ahead of time means nothing on the dashboard surprises you.
- 1
You prepare the files
A formatted interior (an EPUB or print-ready PDF) and a cover. The interior is where most first-timers lose a day โ mismatched fonts, broken page breaks, and missing front matter are common.
- 2
You enter the book's details
Title, subtitle, author name, description, keywords, and two browse categories. This metadata is what readers search and what Amazon uses to rank you, so it is worth more thought than the cover often gets.
- 3
Amazon reviews the submission
An automated and partly manual content-policy check, usually within 72 hours. It catches copyright issues, misleading metadata, and formatting that fails to render.
- 4
The book goes live
Once approved, your title is buyable worldwide and starts accruing a sales rank. Ebooks appear almost immediately; print can take a little longer to propagate.
- 5
Amazon pays you monthly
Royalties are calculated per sale and per page read in Kindle Unlimited, then paid roughly 60 days after the end of each sales month via direct deposit.
Set up your KDP account, step by step
Opening the account takes about fifteen minutes, and the tax and banking steps are the only ones that trip people up. Have your tax ID and bank details on hand before you start.
- 1
Go to kdp.amazon.com and sign in
Use an existing Amazon account or create a dedicated publishing account. A separate email keeps royalty statements and KDP notifications out of your personal inbox.
- 2
Complete your account information
Enter your legal name and address exactly as they appear on tax documents. This becomes the "publisher of record" unless you set a separate imprint name later.
- 3
Add your payment details
Connect a bank account for each marketplace currency you want to be paid in. Amazon pays the US, UK, and EU stores separately, so adding accounts for the big three avoids wire fees later.
- 4
Fill out the tax interview
A short questionnaire that determines your withholding rate. Non-US authors who supply a valid tax ID and treaty country can often reduce US withholding from 30% to 0โ10%.
- 5
Verify your identity if prompted
New accounts are sometimes asked for a quick identity confirmation. Completing it promptly prevents your first title from sitting in review longer than necessary.

Click 'Create a new title' to begin
The Bookshelf is your home base. From here you choose ebook, paperback, or hardcover and walk through the three-tab setup: details, content, and pricing.
Ebook vs paperback vs hardcover
You don't have to pick one โ most authors publish an ebook and a paperback of the same title, and the two share a single product page. Here's how the three formats compare on the decisions that matter.
| Ebook | Paperback | Hardcover | |
|---|---|---|---|
| Up-front cost | None | None | None |
| Royalty model | 35% or 70% of list | 60% of list minus print cost | 60% of list minus print cost |
| Print cost | n/a | Low (per-page + fixed) | Higher (binding premium) |
| Kindle Unlimited | Eligible (page reads) | Not eligible | Not eligible |
| Best for | Fiction, fast launches | Almost every book | Gifts, premium nonfiction |
| Min. page count | None | 24 pages | 75 pages |
The royalty breakdown
Ebook royalties run on two tiers. Price your ebook between $2.99 and $9.99 and you earn 70% of list (minus a tiny per-megabyte delivery fee); price it below $2.99 or above $9.99 and you drop to 35%. That single rule is why so many indie ebooks cluster at $4.99โ$6.99.
Print is different: you earn 60% of the list price minus Amazon's fixed printing cost, which scales with page count. A 300-page paperback costs roughly $4โ$5 to print, so a $14.99 book nets around $4 per sale. The numbers move fast with trim size and page count, which is exactly what a calculator is for.
Run your own numbers
Plug in your price, page count, and trim size to see exact ebook and print royalties before you commit to a list price.
Open the royalty calculatorGoing wide vs KDP Select
KDP Select is Amazon's exclusivity program: enroll your ebook for 90-day terms and it can't be sold as an ebook anywhere else. In exchange you get Kindle Unlimited page-read income and a couple of promo tools. "Going wide" means skipping Select and also selling on Apple Books, Kobo, Google Play, and others.
Choose KDP Select ifโฆ
- Your readers live inside Kindle Unlimited (most genre fiction)
- You want Kindle Countdown Deals and free-day promotions
- Page-read income from KU outweighs other-store sales
- You're launching a series and want binge-reads from subscribers
Go wide ifโฆ
- You write nonfiction or literary work readers buy outright
- You don't want all your eggs in one retailer
- You have an audience on Apple, Kobo, or library platforms
- You sell direct or bundle the ebook with other products
There's no universal right answer. A practical move is to launch a new series in Select to seed KU reads and reviews, then reassess after the first 90-day term โ Select is only a 90-day commitment, not a permanent one.
Common rejection reasons (and how to fix them)
Most KDP rejections come from a short, predictable list. Knowing them in advance turns a frustrating week of resubmissions into a clean first approval. These are the ones we see derail new authors most often.
Cover bleed or spine width is wrong for the page count
Fix: Print covers must match the exact spine width for your final page count and trim size. Generate the cover only after the interior is locked, and use a spine-width calculator rather than guessing.
The interior PDF has fonts that aren't embedded
Fix: Export your print PDF with "embed all fonts" enabled. Unembedded fonts render as boxes on Amazon's printers and trigger an automatic rejection.
Metadata doesn't match the book (misleading title or keywords)
Fix: Keep the title, subtitle, and keywords honest and tied to the actual content. Stuffing competitor names or unrelated bestseller titles into keywords is the fastest route to a block.
Missing or incorrect AI-content disclosure
Fix: Amazon now asks whether AI was used. Answer it accurately: AI-assisted work (you edited and directed it) is allowed and only needs the disclosure โ concealing it risks removal.
Free or public-domain content without added value
Fix: Republishing a public-domain text verbatim is rejected. Add a genuine contribution โ a new translation, annotations, an introduction, or original illustrations โ and explain it in the submission.
Low-quality images or a blurry cover
Fix: Covers need at least 300 DPI at full size. Upscaled thumbnails and screenshots get flagged for image quality; start from a high-resolution source.
An AI-assisted KDP workflow
The slowest part of self-publishing is rarely the upload โ it's writing and formatting a finished manuscript. This is where AIWriteBook fits: it drafts, structures, and exports a clean, KDP-ready book, so the upload steps above become the easy part of the day.
- 1
Generate an outline and chapters
Start from a premise and let the model โ Gemini or Grok โ draft an outline, then full chapters you edit and shape. You stay the author; the AI removes the blank-page friction.
- 2
Edit in the built-in editor
Rewrite, expand, and tighten right in the book editor with inline AI help and a spell checker, until the prose reads the way you want.
- 3
Create a cover and export
Generate a cover, then export a print-ready PDF and EPUB that match KDP's formatting rules โ no fighting with fonts or page breaks.
- 4
Disclose AI use and publish
Answer Amazon's AI question honestly (AI-assisted books are allowed), upload your files, and hit publish. Your title is in review within minutes.

Frequently asked questions
The questions new KDP authors ask most, answered plainly.
Yes. Opening an account and publishing an ebook, paperback, or hardcover costs nothing up front. Amazon takes its cut from each sale through the royalty split, and your only optional costs are things like ordering author copies or buying an ISBN if you want your own.
After you submit, the content review typically finishes within 72 hours. Ebooks usually appear for sale within a day of approval; print titles can take a little longer to show on every marketplace. New accounts sometimes see slightly longer first-time reviews.
An ebook priced $2.99โ$9.99 earns 70% of list (minus a small delivery fee), so a $4.99 ebook nets about $3.43. Print earns 60% of list minus the printing cost, so a $14.99 paperback nets roughly $4. Kindle Unlimited pays per page read, around half a cent per page.
No. Amazon assigns a free ASIN to ebooks and a free ISBN to print books. You only need to buy your own ISBN if you want to be listed as the publisher of record or plan to distribute the print edition beyond Amazon.
KDP Select makes your ebook exclusive to Amazon for 90-day terms in exchange for Kindle Unlimited income and promo tools. Going wide means selling on Apple Books, Kobo, Google Play, and others too. Select suits genre fiction with heavy KU readership; wide suits nonfiction and authors who don't want single-retailer risk.
Yes. Amazon allows AI-assisted and AI-generated books as long as you disclose AI use when prompted during setup. The key is to direct and edit the work so it meets quality and originality standards โ concealed or unedited bulk content is what gets removed.
Yes. You can update the manuscript, cover, price, and metadata at any time from your Bookshelf. Content changes go through a short re-review; price and metadata edits usually take effect within a few hours.
The usual causes are an incorrect spine or bleed on the cover, unembedded fonts in the interior PDF, misleading metadata or keywords, a missing AI disclosure, or republishing public-domain content without adding value. Each has a straightforward fix before resubmitting.
Royalties are paid monthly, roughly 60 days after the end of each sales month, by direct deposit once you pass the minimum threshold for that marketplace. Adding bank accounts for the US, UK, and EU stores lets you avoid wire fees.
Yes, and most authors do. KDP links the ebook and print editions on a single Amazon product page, so a reader sees both formats and chooses. You set up each format separately but they share the same title detail page.
