Amazon Kindle Direct Publishing (KDP) lets you publish and sell books directly to millions of Amazon customers, with no upfront cost and no need for a traditional publisher. You can publish ebooks, paperbacks, and hardcovers, keep your rights, and start earning royalties within days of uploading your manuscript. Here’s how the entire process works, from setting up your account to getting your first sales.
Create Your KDP Account
Go to kdp.amazon.com and sign in with an existing Amazon account or create a new one. You’ll need to complete your author profile with your legal name (or pen name), address, and bank account details for royalty payments. KDP also requires tax information, so have your Social Security number or EIN ready. If you’re outside the United States, you’ll complete a tax interview that determines whether Amazon withholds taxes from your earnings.
Your account is free. Amazon doesn’t charge you to publish, and there’s no subscription fee. You only pay when a book sells, in the form of printing costs (for paperback and hardcover) deducted from your royalties.
Prepare Your Manuscript
KDP accepts several file formats, but the cleanest results come from uploading a Word document (.docx) for ebooks or a press-ready PDF for print books. Formatting matters more than most new publishers expect. For ebooks, keep your layout simple: use paragraph styles for headings, avoid manual spacing, and don’t embed images unless they’re essential. Complex formatting that looks fine in Word can break on a Kindle screen.
For paperbacks and hardcovers, your interior file needs to match the exact trim size you choose (common options include 5″ x 8″, 5.5″ x 8.5″, and 6″ x 9″). Set your margins to account for the gutter, which is the space lost in the book’s spine. KDP provides templates you can download for each trim size, and using one saves a lot of trial and error.
If your book contains AI-generated content, including text, images, or translations, Amazon requires you to disclose that during the upload process. This applies to content that is fully AI-generated, not material where AI simply assisted your own writing process.
Design a Cover That Sells
Your cover is the single biggest factor in whether a shopper clicks on your book. Amazon displays covers as small thumbnails in search results, so the title needs to be readable even at a tiny size. Study the top-selling books in your genre and notice the patterns: thriller covers look different from romance covers, which look different from self-help covers. Matching those visual conventions signals to readers that your book belongs in the category they’re browsing.
KDP offers a free Cover Creator tool, but it produces generic results. If your budget allows, hiring a professional cover designer (typically $200 to $500 for an ebook cover, more for print) is one of the best investments you can make. For print books, your cover file must include the front, spine, and back as a single image, and the spine width depends on your page count. KDP’s cover calculator generates a template with the correct dimensions.
Set Up Your Book’s Details
When you create a new title in your KDP dashboard, you’ll fill out metadata that determines how readers find your book. This step deserves careful attention.
- Title and subtitle: Your subtitle is searchable on Amazon, so use it to include relevant descriptive phrases that readers might type into the search bar.
- Book description: This is your sales pitch. Write it like back-cover copy, not a summary. Focus on what makes a reader want to open the book. You can use basic HTML formatting (bold, italics, line breaks) to make it scannable.
- Categories: You can select up to three categories when publishing. Pick the most specific categories that accurately describe your book. A narrow category with less competition gives you a better chance of ranking as a bestseller in that niche.
- Keywords: KDP gives you seven keyword boxes. Fill all of them with phrases your target reader would actually search for. Think like a shopper, not a librarian. “cozy mystery small town female detective” is more useful than “fiction” or “mystery.”
Choose Your Pricing and Royalty Rate
For ebooks, KDP offers two royalty options. The 70% royalty plan applies to books priced between $2.99 and $9.99 and is available in select territories. A small delivery fee based on file size is deducted from each sale. The 35% royalty plan applies to books priced outside that range, with no delivery fee. Most authors price ebooks between $2.99 and $4.99 to stay in the 70% tier while remaining competitive.
For paperbacks and hardcovers, you earn a 60% royalty minus the printing cost. Printing costs depend on page count, ink type (black and white or color), trim size, and marketplace. A 200-page black-and-white paperback might cost roughly $3 to $4 to print, which means you’d need to price it high enough to cover that cost and still earn a meaningful royalty. KDP’s pricing calculator on the dashboard shows your exact per-copy cost and royalty before you publish.
Publish and Review Your Proof
Once you upload your files and fill out all the details, click “Publish.” Amazon reviews every new book, which typically takes 24 to 72 hours. For print books, order a proof copy before making it available for sale. The digital previewer catches some formatting issues, but holding the physical book reveals problems you won’t see on screen: margins that feel too tight, fonts that look too small, or a cover color that prints differently than it appeared on your monitor.
After approval, your book gets its own product page on Amazon with a unique ISBN (KDP provides free ISBNs for print books) or ASIN for ebooks. You can make changes to your book’s content or details at any time, though updates take another 24 to 72 hours to go live.
Decide Whether to Enroll in KDP Select
KDP Select is an optional program that gives your ebook extra promotional tools in exchange for digital exclusivity. You agree not to sell or distribute the digital version of your book anywhere else for 90 days. Print editions can still be sold through other retailers, and you can send digital copies to reviewers.
The biggest benefit is enrollment in Kindle Unlimited (KU), Amazon’s subscription reading service. KU readers can borrow your book at no cost, and you earn royalties based on pages read from a shared monthly fund. For genres where KU readers are active, particularly romance, science fiction, fantasy, and thrillers, this can significantly boost your income and visibility.
You also get access to two promotional tools. Kindle Countdown Deals let you discount your book for up to one week every 90 days while still earning a 70% royalty on the sale price, even if the discounted price drops below $2.99. Your book’s regular price must be between $2.99 and $24.99 to qualify. Kindle Free Promotions let you offer your book for free for up to five days per 90-day enrollment period. You can’t run both in the same enrollment cycle.
KDP Select auto-renews every 90 days unless you opt out before the period ends. If you want to sell ebooks on other platforms like Apple Books, Kobo, or Barnes and Noble, skip KDP Select and go “wide” instead.
Drive Traffic to Your Book
Publishing on Amazon doesn’t automatically generate sales. You need a plan to get your book in front of readers.
Amazon Ads is the most direct option. You can run Sponsored Products campaigns that place your book in search results and on competitor product pages. Start with a small daily budget ($5 to $10), target keywords your readers search for, and monitor which terms convert to sales. Advertising on Amazon has a learning curve, but even modest campaigns can increase your book’s visibility enough to trigger the algorithm, which then recommends your book to more shoppers organically.
Outside Amazon, build an audience through an email list, social media, or a simple author website. An email list is especially valuable because you can notify subscribers directly whenever you release a new book or run a promotion. Many successful KDP authors say their email list generates more reliable sales than any other channel.
Reviews matter enormously. Books with more reviews rank higher in search results and convert more browsers into buyers. Encourage readers to leave honest reviews by including a brief, polite request at the end of your book. You can also use Amazon’s editorial review section to feature quotes from bloggers or early readers.
Track Sales and Get Paid
Your KDP dashboard shows sales and royalty data, though numbers update with a slight delay (usually a few hours for ebook sales, longer for print). You can view reports by title, marketplace, and date range. Royalties are paid approximately 60 days after the end of the month in which the sale occurred. If your book sells in March, expect payment around the end of May. Payments go directly to the bank account you set up during registration, and you can choose to be paid by electronic transfer or check.
If you enrolled in KDP Select, your Kindle Unlimited page reads show up in a separate report. KU royalties are calculated monthly based on a global fund that Amazon sets, divided among all participating authors proportionally by pages read. The per-page rate fluctuates but has historically hovered around half a cent per page, meaning a 300-page book read in full earns roughly $1.30 to $1.50 from that single borrow.
Scale With More Titles
The most reliable way to increase your KDP income is to publish more books. Each new title gives you another product page on Amazon, another entry point for readers to discover you, and another chance to cross-promote your backlist. Authors who build a catalog of related books in the same genre almost always out-earn those with a single title, because a reader who finishes one book and enjoys it will often buy the next.
Link your books together using Amazon’s series feature, include “also by” pages in your manuscripts, and consider pricing your first book lower (or making it free through a KDP Select promotion) to pull readers into the series. The first book becomes a marketing tool, and the later books generate the profit.
