KDP publishing questions, answered.

Create a free account at kdp.amazon.com, click Create New Title, choose paperback, hardcover, or ebook, then fill out three sections: Details (title, author, description, keywords, categories), Content (upload your interior PDF or ebook file plus your cover), and Pricing (set list price, choose royalty plan, select marketplaces). The full setup takes about 30 to 60 minutes for your first book and 10 to 15 minutes for subsequent ones. After clicking Publish your book enters KDP review, which typically completes in 24 to 72 hours, after which it goes live on Amazon.

Yes. Creating a KDP account is free, listing your book is free, and there are no upfront fees or recurring charges. KDP makes money by taking a cut of your royalties: 30 to 40 percent on ebooks depending on your royalty plan, plus printing costs deducted from paperback and hardcover royalties. You only pay if you choose paid services like Amazon Ads or order author copies of your physical book at print cost ($2.15 minimum for a 6 x 9 paperback, plus $0.012 per page for black-and-white interiors).

Earnings range from $0 to seven figures annually, with the median self-published author earning under $1,000 per year per book and the top 1 percent earning over $100,000 per year. Realistic expectations for a first book with no audience: $50 to $500 in the first three months, growing with reviews and additional titles. The reliable path to meaningful income is publishing multiple books (5 to 20+) in a focused niche, building an email list, and writing in series. Low-content books (journals, planners, coloring) typically earn $1 to $5 per sale and rely on volume across many titles.

KDP reviews typically complete within 72 hours, and most books are processed in 24 to 48 hours. The clock starts when you click Publish, not when you finish uploading files. Updates to existing live books (cover changes, blurb edits, manuscript revisions) usually go through faster, often within 12 to 24 hours. First-time accounts, higher-risk genres (adult content, controversial topics), and books that trigger automated content flags can take 5 to 7 business days. If your book is rejected you get an email explaining why and your title moves to Draft status until you fix and resubmit.

No for ebooks (KDP assigns a free ASIN, which is Amazon-only). No for paperback and hardcover either: KDP provides a free ISBN if you want one, listing the imprint as "Independently Published". You only need to buy your own ISBN ($125 single from Bowker in the US, or $295 for 10) if you want to use your own publishing imprint name on the copyright page and Amazon listing, or if you plan to distribute outside KDP (to bookstores, libraries, IngramSpark). For most self-publishers selling exclusively on Amazon, the free KDP ISBN is sufficient.

Ebooks: choose between 70 percent royalty (for books priced $2.99 to $9.99, after delivery fee deducted) or 35 percent royalty (for any price from $0.99 to $200, no delivery fee). Paperbacks: 60 percent of list price minus printing cost. Hardcovers: 60 percent of list price minus printing cost. The printing cost for a 200-page 6 x 9 black-and-white paperback is $3.55, so at a $14.99 list price your royalty is (14.99 × 0.60) - 3.55 = $5.44. Royalties vary slightly by marketplace and currency.

The 60 percent royalty applies to paperback and hardcover books and is calculated as 60 percent of list price minus printing cost. The 70 percent vs 35 percent split applies only to ebooks: 70 percent requires a list price between $2.99 and $9.99 (Amazon also deducts a small delivery fee based on file size, typically $0.06 to $0.15), while 35 percent is available at any price from $0.99 to $200 with no delivery fee. For a $9.99 ebook, 70 percent earns about $6.85 after delivery fee versus 35 percent earning $3.50; for a $14.99 ebook priced above the 70 percent band, 35 percent earns $5.25 and is the only available option.

For ebooks, pricing at $2.99 to $9.99 is almost always best because the 70 percent royalty kicks in (about $2.05 to $6.85 per sale) versus 35 percent above $9.99. Sweet spots by genre: $0.99 to $2.99 for new authors building an audience in fiction, $3.99 to $5.99 for established indie fiction, $9.99 for non-fiction. For paperbacks, work backward from a $4 to $6 target royalty: a 200-page 6 x 9 black-and-white paperback with $3.55 printing cost needs a $12.99 list price for $4.24 royalty. Hardcovers typically price $5 to $10 above paperback to cover the higher printing cost.

KDP allows seven keyword fields per book, each up to 50 characters. Use long-tail search phrases (3 to 5 words) that actual Amazon shoppers type, not single broad words. Research with the Amazon search bar autocomplete, third-party tools like Publisher Rocket, or KDPEasy keyword research. Avoid keywords that duplicate your title, author name, or category (Amazon already indexes those), avoid trademarked brand names (Disney, Harry Potter), and never use subjective words like "best" or "amazing". Strong examples for a romance novel: "small town romance second chance", "billionaire enemies to lovers", "clean wholesome contemporary romance".

KDP allows exactly seven keyword fields per book, each with a 50-character maximum (including spaces). That works out to roughly 350 characters total of keyword real estate, and Amazon indexes every word in every field for search results. You can update keywords any time from the Edit Details page; changes are typically reflected in search within 72 hours. KDP also assigns ten browse categories automatically based on your selected categories and content, on top of the two categories you choose at publication, so do not waste keyword fields on category names that are already covered.

You pick two categories at publication and can request up to ten total through KDP support. Pick the most specific subcategories possible (level 3 or 4 deep, like Books > Romance > Contemporary > Holidays rather than just Books > Romance), because narrow categories have less competition and are easier to rank in. Browse the actual Amazon category tree to find categories where the #20 ranked book sells fewer than 50 copies per day, signaling beatable competition. To add more than two, email content-review@amazon.com after publication with up to eight additional categories formatted as full path strings.

Yes. KDP allows you to publish under any pen name you choose, set during book creation as the Author field. You can have multiple pen names from a single KDP account (one account, many pen names), which is the standard approach for authors writing in multiple genres. The pen name appears on your Amazon listing, the cover, and in search results; your real name appears only on tax forms, payment records, and the KDP backend, never publicly. To build a separate author brand you can also create an Amazon Author Central page for each pen name with its own bio and photo.

Three reliable paths to a first sale: (1) tell your existing network via email, social media, and direct message, asking 20 to 50 friends and family to buy and leave honest reviews; (2) run a 99-cent launch price for the first week and a free promo through KDP Select to seed downloads and reviews; (3) start Amazon Ads with a $5 daily budget targeting 30 to 50 specific competitor titles in your niche. Realistic timeline: 5 to 20 sales in the first month from network and launch promo, then 1 to 5 sales per day if your cover, blurb, and reviews are strong enough to convert from organic search.

KDP Select is an optional 90-day enrollment program for ebooks (not paperbacks or hardcovers) that requires exclusivity to Amazon in exchange for two benefits: inclusion in Kindle Unlimited (KU) where subscribers can read your book for free and you earn around $0.0045 per page read, and access to five promotional days per 90-day term (free book days or Kindle Countdown Deals). Worth enrolling if: your readers are heavy KU users (romance, thrillers, fantasy, cozy mysteries), you have no audience on other platforms, or your book is over 100 pages so the page-read income is meaningful. Skip it if: you sell well on Apple Books, Kobo, or your own site, or you have an existing audience on non-Amazon platforms.

In KDP, click Create New Title and select Paperback. Enter book details (title, subtitle, author, description, keywords, categories), then upload two files in the Content step: an interior PDF formatted to your chosen trim size with embedded fonts, and a full-wrap cover PDF including front, spine, and back. Choose paper type (white, cream, or color), bleed setting, and ISBN option (free KDP ISBN or your own). Set list price in the Pricing step and choose distribution to the marketplaces you want. Click Publish; review typically takes 24 to 72 hours. Order a proof copy ($2 to $5 plus shipping) before final publication to check print quality.

Hardcover publishing works almost identically to paperback: click Create New Title, select Hardcover, fill in Details, upload your interior PDF and a hardcover-sized cover PDF in the Content step (hardcover covers are larger than paperback due to wrap-around allowance for the boards), set price in Pricing. Hardcovers require a minimum 75 pages (paperbacks allow as few as 24). Printing cost is higher: a 200-page 6 x 9 hardcover costs about $6.80 to print versus $3.55 for paperback. List price typically runs $5 to $10 higher than the paperback equivalent. Only five trim sizes are supported for hardcover, all with case laminate binding.

Create New Title, select Kindle eBook, fill in details, then upload your manuscript in the Content step. KDP accepts .doc, .docx, .epub, .kpf (Kindle Create), and .mobi files, with .epub being the most reliable format. Upload a cover JPG at 2560 x 1600 pixels (1.6:1 ratio). Enable DRM if you want (most authors disable to avoid hassling readers), set categories and age range, then move to Pricing where you choose 35 percent or 70 percent royalty plan and list price between $0.99 and $200. Click Publish. Ebook reviews are typically faster than print, often live within 12 to 24 hours.

Yes, and you absolutely should. KDP automatically links the paperback, hardcover, and ebook versions of the same title under one Amazon listing (called a "series link") so all three appear on the same product page with format options at the top. Most authors publish ebook first, then paperback within a few days, then hardcover later. Reviews and ratings pool across all formats, which boosts conversion. To link them properly, use the exact same title, subtitle, and author name across all formats; KDP usually auto-links within 72 hours, otherwise contact KDP support with the ASINs to merge them manually.

During the Paperback or Hardcover setup, in the Print ISBN section, select "Get a free KDP ISBN" and KDP instantly assigns one to your title. The imprint on the copyright page and Amazon listing will be "Independently Published" and the ISBN is locked to KDP only (you cannot use it to distribute the same book through IngramSpark, Draft2Digital, or other channels). If you later want to publish elsewhere, you must buy a separate ISBN and republish as a new edition. Ebooks do not need an ISBN at all because KDP assigns a free ASIN (Amazon Standard Identification Number) automatically.

KDP requires a minimum of 24 pages for paperbacks and 75 pages for hardcovers. The maximum page count is 828 pages for paperbacks and 550 pages for hardcovers. For low-content books (journals, planners, notebooks, coloring books) 24 pages is rarely enough to bind properly with spine text, so most low-content publishers aim for 100 to 150 pages to get a spine wide enough to be usable. Ebooks have no minimum page count but books under 24 pages cannot be enrolled in KDP Select Kindle Countdown Deals.

Low-content books (notebooks, journals, planners, logbooks, coloring books) follow the same KDP publishing flow as regular paperbacks: trim size, page count, white or color paper, full-wrap cover PDF, interior PDF. Most low-content publishers use 6 x 9 or 8.5 x 11 trim, 100 to 150 pages, white paper, with a simple interior PDF of repeating page templates. The keyword "low-content" was removed from KDP categories in 2023 but the format is still allowed; just publish as a regular paperback. Realistic earnings: $1 to $3 royalty per sale, with successful publishers earning income from publishing 50 to 500+ titles in a niche.

Amazon Advantage is a wholesale program for traditional publishers and distributors selling printed inventory to Amazon, where Amazon holds physical stock and resells, and the vendor pays Amazon a 55 percent wholesale discount plus a $99 annual fee. KDP is the self-publishing platform where Amazon prints copies on demand as orders come in (no inventory, no upfront cost) and you earn 60 percent royalty minus print cost. For self-published authors, KDP is almost always the right choice; Amazon Advantage is geared toward publishers who already manufacture books in bulk. KDP also handles ebooks and digital distribution, which Advantage does not.

KDP pays royalties via direct deposit (Electronic Funds Transfer / EFT) about 60 days after the end of each sales month, e.g. January sales pay out around late March. Set up payment in KDP Account > Payment Information by adding your bank account for each marketplace currency where you earn (USD, GBP, EUR, etc.), or take wire transfer / check if EFT is unavailable in your country. The minimum payout threshold is $10 to $100 depending on marketplace and payment method; balances below threshold roll forward until reached. Wise (formerly TransferWise) virtual account numbers are popular for non-US authors receiving USD royalties.

Yes. KDP earnings are self-employment income in the US (reported on Schedule C and subject to income tax plus 15.3 percent self-employment tax), or business income in most other countries. KDP requires you to complete a W-9 (US residents) or W-8BEN (non-US residents) tax form during account setup to determine withholding. Without a US tax form non-US authors face 30 percent automatic withholding on US royalties, which can be reduced to 0 to 10 percent under most US tax treaties via the W-8BEN. KDP issues 1099-MISC forms to US authors earning over $600 per year in January for the prior tax year; non-US authors receive equivalent royalty statements they can download from KDP.
