The complete Amazon KDP publishing FAQ.

Go to kdp.amazon.com and sign in with your existing Amazon account or create a new one (free). Complete three onboarding sections: Account Information (legal name, address, country of residence), Tax Information (W-9 for US residents, W-8BEN for non-US), and Payment Information (bank account in each marketplace currency you earn in). The full setup takes 15 to 30 minutes. You can publish your first book the same day. KDP supports authors from over 100 countries; the only countries explicitly blocked are those on US sanctions lists.

Yes. Creating a KDP account is free, listing books is free, and there are no recurring charges. Amazon takes its cut from royalties: 30 to 65 percent on ebooks depending on your royalty plan and price, plus printing cost deducted from paperback and hardcover royalties. You only pay for optional services: Amazon Ads (your chosen daily budget), author proof copies (printed at cost plus shipping, e.g. $2.15 for a 24-page 6x9 paperback), or your own ISBN if you skip the free KDP one ($125 from Bowker in the US).

Click Create New Title and select Paperback. Fill in Details (title, subtitle, author, description, keywords, categories), upload your interior PDF and full-wrap cover PDF in the Content step, choose paper type, bleed, and ISBN option, set price in Pricing, click Publish. Review typically completes in 24 to 72 hours. Always order a proof copy ($2 to $5 plus shipping) before final publication to catch print issues. KDP minimum page count is 24 for paperback and 75 for hardcover; maximum is 828 pages.

KDP review typically completes 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. Rejected titles return to Draft with an email explaining the issue.

For paperback and hardcover, KDP offers a single 60 percent royalty plan calculated as 60 percent of list price minus printing cost in each marketplace. The 40 percent figure people sometimes mention applies only to paperbacks distributed through Expanded Distribution (to bookstores and libraries via Ingram), which earns 40 percent of list minus printing. So if you sell direct on Amazon you earn 60 percent; if Amazon resells the same book through Expanded Distribution to a third-party retailer, that copy earns 40 percent. Most KDP authors stick with the 60 percent direct-sale plan.

For Kindle ebooks, you pick a royalty plan at publication. 70 percent requires a list price between $2.99 and $9.99 in USD (with regional equivalents) and a small delivery fee deducted by Amazon based on file size (typically $0.06 to $0.15). 35 percent applies to any price from $0.99 to $200 with no delivery fee. At a $9.99 ebook the 70 percent plan earns about $6.85 after delivery fee, versus $3.50 on the 35 percent plan. Above $9.99 only the 35 percent plan is available, so a $14.99 ebook earns $5.25.

KU subscribers read your KDP Select enrolled books "free" and you earn from the KDP Select Global Fund, which Amazon allocates monthly based on total qualifying page reads across all KU titles. The per-page payout (KENPC rate) typically lands between $0.0040 and $0.0050 per page in 2026. A 300-page novel fully read by one KU subscriber earns roughly $1.20 to $1.50, compared with $2.05 royalty on a $2.99 sale at 70 percent. KU only pays for pages actually read, not borrows, so books that hook readers early outperform those with slow openings.

Yes. The free KDPEasy royalty calculator at kdpeasy.com/tools/kdp-royalty-calculator computes paperback, hardcover and ebook royalties across US, UK, EU and other Amazon marketplaces, factoring in the right print cost for your trim, page count, paper type, and ink. Plug in trim 8.5x11, 100 pages, white paper, black ink and $7.99 list price and it returns $1.17 per sale on Amazon US. The Amazon KDP calculator inside the KDP dashboard during pricing setup is also accurate but does not save scenarios or compare price points side-by-side.

Earnings range from $0 to seven figures annually. The realistic distribution: median self-publisher earns under $1,000 per year per book; the top 10 percent earn $5,000 to $30,000 across a portfolio; the top 1 percent earn over $100,000 per year. A first book with no audience typically earns $50 to $500 in the first three months. Meaningful income comes from publishing multiple books (5 to 20+) in a focused niche, building an email list, and writing in series. Low-content books earn $1 to $5 per sale and rely on portfolio volume.

KDP Select is an optional 90-day ebook-only enrollment program that requires Amazon exclusivity for the ebook (your paperback and hardcover are unaffected). In exchange you get two benefits: inclusion in Kindle Unlimited (KU) where subscribers read for free and you earn $0.0040 to $0.0050 per page read, plus 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) or you have no audience elsewhere. Skip if you sell well on Apple Books, Kobo, or your own site.

When you enroll an ebook in KDP Select the digital version must be exclusive to Amazon for the full 90-day term: you cannot sell or distribute it on Apple Books, Google Play Books, Kobo, Barnes & Noble Nook, your own website, or as a PDF. You can still sell the paperback and hardcover anywhere. Free promotional PDFs given to your email list are technically a violation; safer is to gift the Kindle version directly through Amazon. Enrollment renews automatically every 90 days unless you turn off auto-renew in the KDP dashboard.

Expanded Distribution lets your paperback (not hardcover or ebook) sell through bookstores, libraries, and academic institutions via Ingram. The trade-off: royalty drops from 60 percent to 40 percent on those copies and Amazon often matches the lower price across its own listings, which can erode your direct-sale royalty too. Worth enabling if: you target libraries or bookstores, or you publish non-fiction with academic appeal. Skip if you are an Amazon-only author or rely on tight margins. Most low-content and puzzle-book publishers leave it off; most fiction authors leave it on.

KDP automatically distributes to 13 Amazon marketplaces: US (.com), UK (.co.uk), Germany (.de), France (.fr), Spain (.es), Italy (.it), Netherlands (.nl), Japan (.co.jp), Brazil (.com.br), Canada (.ca), Mexico (.com.mx), Australia (.com.au), and India (.in). You set the list price in each marketplace currency or let KDP auto-convert from USD. Print-on-demand is supported in US, UK, EU and Australia; orders from Japan or India typically print in another region and ship in. International royalties are paid in local currency to your matching bank account.

Ebooks: price $2.99 to $9.99 to unlock the 70 percent royalty band. Sweet spots by genre: $0.99 to $2.99 for new fiction authors building an audience, $3.99 to $5.99 for established indie fiction, $9.99 for non-fiction. Paperbacks: work backward from a $4 to $6 target royalty. A 200-page 6x9 black-and-white paperback prints for $3.55, so $12.99 list earns $4.24 royalty. Hardcovers typically price $5 to $10 above the paperback to cover the higher print cost. Test 2 to 3 price points over 30 days each and compare daily revenue, not just unit sales.

Paperback is a softcover bound paperbound book; hardcover is a rigid case-bound book with a stiff cardboard cover and dust jacket. On Amazon both publish through KDP. Paperback supports trim sizes from 5x8 up to 8.5x11 and prints from $2.15 minimum; hardcover supports only 5 trim sizes (5.5x8.5, 6x9, 6.14x9.21, 7x10, 8.25x11) and prints from $6.80 for a 200-page 6x9. Hardcover usually sells for $5 to $10 more than the paperback equivalent. Paperback outsells hardcover roughly 5 to 10 to 1 in most categories.

On Amazon, "paperback" means a printed, perfect-bound softcover book printed on demand through KDP. The cover is a flexible card stock (usually 80lb or 100lb gloss or matte laminate); the interior is 60lb white or cream paper. Each paperback is printed individually when a customer orders, so there is no inventory cost to the author. The same listing can include Kindle, paperback, and hardcover formats which Amazon links together at the top of the product page. Paperback is the most popular format on KDP and accounts for the majority of self-publisher revenue.

Yes, KDP provides a free ISBN for paperback and hardcover books. The imprint on the copyright page and Amazon listing shows as "Independently Published" and the ISBN is locked to KDP only - you cannot use the same ISBN to distribute the book elsewhere (IngramSpark, Draft2Digital, your own website). Ebooks do not need an ISBN at all; KDP assigns a free ASIN (Amazon Standard Identification Number) automatically. If you ever want to distribute outside Amazon you must buy your own ISBN and republish as a new edition.

Free KDP ISBN is fine if you publish exclusively on Amazon and do not mind the "Independently Published" imprint. Buy your own ISBN ($125 single, $295 for 10 from Bowker in the US) if: you want your own publishing imprint name on the copyright page, you plan to distribute through IngramSpark or Draft2Digital, you want to walk a copy into a local bookstore, or you are building a serious publishing brand. Each format (paperback, hardcover, ebook) needs its own ISBN, so a single book published in all three formats uses three ISBNs.

No, not specifically. The free KDP ISBN works fine for paperback coloring and puzzle books, and the ebook ASIN is automatic. The only reason to buy your own ISBN is if you plan to sell outside Amazon (rare for low-content books) or you want a custom imprint name on the copyright page. Many low-content publishers run 100+ titles entirely on free KDP ISBNs without issue. If you ever expand to IngramSpark for wider distribution you will need your own ISBNs at that point.

No, KDP adds the ISBN barcode to your paperback cover automatically during publishing if you use their free ISBN. If you supply your own ISBN you can let KDP add the barcode for you (recommended, easier) or generate one yourself with a free ISBN barcode generator like Bookow (bookow.com), the free option from BarcodesInc, or KDPEasy. Place the generated barcode in the bottom-right of the back cover with a 0.25 inch margin from edges. Amazon ASIN barcodes are not needed because ASINs are digital-only identifiers.

Start with Amazon search bar autocomplete: type the first 3 to 4 letters of your topic into the Amazon books search and note every suggestion. Then use a paid keyword tool: Publisher Rocket ($199 lifetime, the industry standard), KDPEasy keyword research (subscription, includes niche scoring), or Helium 10. Look for long-tail phrases (3 to 5 words) with 100 to 1,000 monthly searches and weak top-10 competitors (under 30 reviews each). Avoid generic single-word keywords, duplicates of your title or category, and trademarked terms (Disney, Harry Potter).

Publisher Rocket is the most popular paid tool ($199 one-time) and shows search volume, competitor data, and AMS keyword data for ad targeting. KDPEasy keyword research is the best subscription option for ongoing niche scoring across coloring, puzzle and journal niches. Helium 10 works for KDP authors who also sell physical products. Free alternatives: Amazon search autocomplete plus manual Amazon search results inspection (look at the #20 ranked book's daily sales as your competition benchmark). For most authors Publisher Rocket pays for itself within one book.

KDP allows exactly seven keyword fields per book, each with a 50-character maximum including spaces. That works out to roughly 350 characters of keyword real estate total. Amazon indexes every word in every field for search. You can update keywords any time from the Edit Details page; changes typically appear in search within 72 hours. Do not duplicate words across fields, do not repeat your title or author name (Amazon indexes those automatically), and do not use trademarked terms or subjective claims like "best" or "amazing".

You select 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, e.g. Books > Romance > Contemporary > Holidays rather than just Books > Romance). 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 categories email content-review@amazon.com after publication with up to eight additional category paths formatted as full strings.

A+ Content is a free enhanced product description module that adds image, comparison and structured-text blocks beneath your book's standard description on the Amazon listing. It typically lifts conversion 5 to 15 percent on books with 25+ reviews. Use it once your title has traction. Build modules in the KDP dashboard under Marketing > A+ Content Manager: combine cover-detail images, author photos, comparison tables vs similar books, and short benefit-driven copy blocks. Avoid testimonial quotes (Amazon often rejects them). Approval takes 7 days. Reuse the same A+ across series titles to save time.

Amazon Ads runs through the Amazon Advertising console (separate from KDP) and offers Sponsored Products (the workhorse), Sponsored Brands (HQ banner with multiple titles), and Sponsored Display (retargeting). Sponsored Products is where 90 percent of KDP authors should start: pick 30 to 60 competitor ASINs, bid $0.30 to $0.80 CPC, set a $5 to $10 daily budget, and let it run for 14 days before optimizing. Typical ACoS (ad-spend as percent of attributed sales) sits at 25 to 40 percent. Profitable when royalty per sale exceeds ad cost per sale.

Four strategies that work in 2026: (1) ASIN targeting on 30 to 60 specific competitor books in your niche, far more efficient than broad keyword targeting; (2) Auto campaigns set to "loose match" to mine new keyword and ASIN ideas, then graduate winners into manual campaigns; (3) "Brand defense" ads targeting your own author name and series so competitors do not steal your traffic; (4) Sponsored Brands for series authors with 3+ books to drive cross-title reads. Avoid broad keyword targeting at high bids; conversion is far weaker than ASIN targeting for books.

Start with $5 to $10 per day for the first 14 days while you gather data. After 14 days analyze ACoS: if under your break-even (typically 60 percent ACoS for fiction, lower for non-fiction), scale up 25 percent every 3 days as long as ACoS stays profitable. Most new KDP authors plateau at $20 to $50 daily spend per book; six-figure self-publishers commonly spend $100 to $500+ per day across portfolios. Track Read-Through (sales of book 2 after book 1) to value ads correctly for series; ACoS alone undervalues series traffic.

Amazon allows any verified purchaser to leave a review and rating. Reviews from friends and family are technically against Amazon's policy and can be removed; reviews from people you know online (Facebook friends, beta readers) are also risky. Safer: build an ARC (Advanced Review Copy) team of unrelated readers through StoryOrigin, BookFunnel or Booksprout, send them ebook copies before launch, and ask for honest reviews. Never offer payment or free product in exchange for positive reviews. Most successful indie books accumulate 20 to 50 reviews in the first 90 days and 100 to 500+ over a year.

Amazon allows Kindle ebook returns within 7 days of purchase if the customer has read less than 10 percent of the book; the refunded copy reverses out of your royalty in the next month. Paperback and hardcover returns follow Amazon's standard 30-day return policy and the returned royalty is also reversed. Excessive ebook returns (over 10 percent of sales) can trigger a KDP investigation; the most common cause is a misleading description or cover. To minimize returns make sure your sample reads cleanly, your cover matches the genre, and your description accurately describes the actual book.

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

Amazon automatically collects and remits VAT on ebook and paperback sales to EU and UK customers; you do not need to register for VAT yourself in any of those markets just to publish on KDP. Your displayed list price in the UK or EU is the VAT-inclusive consumer price, and your royalty is calculated from the net price (list minus VAT) which makes EU royalties look lower than US royalties at the same list. For example a £9.99 paperback in the UK with 0 percent VAT on print books pays full royalty, but ebooks in the UK and EU carry 0 to 20 percent VAT depending on the country.

KDP pays royalties via Electronic Funds Transfer (EFT) about 60 days after the end of each sales month (January sales pay out late March). The minimum payout threshold is $10 to $100 depending on marketplace and payment method: $10 EFT in the US, GBP10 in the UK, EUR10 in EU markets, with higher thresholds ($100) for check and wire transfer in countries without EFT. Balances below threshold roll forward until reached. Wise (formerly TransferWise) virtual account numbers are popular for non-US authors receiving USD royalties without needing a physical US bank account.

The reliable beginner path: pick one focused niche (a specific fiction sub-genre, a specific non-fiction expertise, or a low-content category like puzzles or journals), publish 3 to 5 titles in that niche over 3 to 6 months, run small Amazon Ads to seed traffic, build an email list with a free lead magnet, and reinvest profits into more titles. Expect $0 to $50 in month 1, $50 to $300 in months 2 to 3, and meaningful momentum by month 6 if covers and keywords are competitive. Quitting after one book is the most common failure pattern.

Three approaches reliably clear $20 per month on a single new book: (1) launch promo with a 99-cent first week and 5 KDP Select free days to seed 100+ downloads and 10+ reviews; (2) Amazon Ads at $5 daily on 30 to 50 competitor ASINs which typically lifts a book to 1 to 3 organic sales per day; (3) email list seeding where 50 to 200 subscribers buy your book in the first week. Compound effect: hitting $20 per month per book across 5 to 10 books gets you to $100 to $200 monthly, the foundation of a meaningful portfolio.

The KDP Terms and Conditions (kdp.amazon.com/help/topic/G200635650) cover four areas most authors should know: (1) content quality and copyright (you must own or have rights to everything you upload); (2) pricing parity (your KDP list price must not be higher than the same book on another platform, or Amazon may price-match and cut your royalty); (3) content guidelines (no plagiarism, copyright infringement, hate content, or undisclosed AI content); and (4) account suspension rules (repeated violations or "manipulation" of sales rank, reviews or KU page reads can trigger termination).

Since September 2023 KDP requires authors to disclose AI-generated content during publishing. Two categories: AI-generated (content created end-to-end by an AI tool, even if you edited it) and AI-assisted (you wrote the content and used AI for editing or brainstorming). You must disclose AI-generated text, images, and translations; AI-assisted work does not require disclosure. The disclosure is private to KDP and never appears on your book page. KDP also limits the number of new titles you can publish per day (currently 3) to curb low-quality AI flooding. Honest disclosure protects your account.
