The Short Answer
Yes, Kindle publishing can still be profitable, but not the way many courses describe it. Amazon's Kindle Direct Publishing (KDP) is free to use and pays real royalties, and some authors earn a living from it. But the store is crowded, AI-generated books have flooded many categories, and most books sell only a handful of copies.
The authors who do well usually write in genres with hungry readers, such as romance, thrillers and fantasy, publish a series, invest in good covers and editing, and treat marketing as part of the job. If you're hoping to upload low-effort books and collect passive income, the odds are poor.
How KDP Royalties Work
KDP pays a share of each sale. For ebooks, you choose between two royalty options; for paperbacks, Amazon deducts printing costs from your share.
| Format | Royalty | Key Conditions |
|---|---|---|
| Ebook, 35% option | 35% of list price (excluding VAT) | Works at any allowed price |
| Ebook, 70% option | 70% of list price, minus delivery costs | Eligible price range and territories; public domain works excluded |
| Paperback (Amazon.com) | 60% of list price minus printing, at $9.99 or more; 50% below that | Printing cost depends on page count and ink |
| Paperback, Expanded Distribution | 40% minus printing | Sales through other retailers |
Amazon's own example: a $15 paperback with 333 black-and-white pages earns (0.60 × $15) − $5.00 printing = $4.00 per copy. Ebook delivery costs average about $0.06 per sale on the 70% option, according to KDP.
The $4.99 ebook figure assumes the 70% option and average delivery costs; your actual royalty depends on file size, VAT and territory.
Kindle Unlimited and KDP Select
If you enroll an ebook in KDP Select, it must be exclusive to Amazon in digital form, and in return it's included in Kindle Unlimited, Amazon's subscription library. You're paid for pages read from a shared monthly fund rather than per sale. For many fiction authors, page reads are a large share of income; the per-page rate changes each month and works out to a fraction of a cent.
What It Costs to Publish a Good Book
| Item | Do It Yourself | Hire It Out |
|---|---|---|
| Writing | Your time | Ghostwriters can cost hundreds to thousands per book |
| Editing | Self-editing | Often several hundred dollars or more |
| Cover design | Free tools | From under $100 to several hundred |
| Formatting | Free tools | Usually modest |
| Ads (Amazon, Facebook) | Optional | Ongoing, often the biggest cost |
| Publishing on KDP | Free | |
Many "Kindle business" courses teach hiring ghostwriters and running ads. That can work, but it means spending money up front on books that may not earn it back.
What Has Changed: AI and Competition
AI tools make it easy to produce books quickly, and many categories are now crowded with low-quality titles. Amazon requires publishers to tell it when a book contains AI-generated text, images or translations; content you wrote yourself and only edited or brainstormed with AI doesn't need disclosure. KDP's content guidelines also let Amazon remove books that give readers a poor experience.
The result: quick, low-effort books are harder to profit from, while books readers genuinely enjoy still stand out.
Fiction vs Nonfiction vs Low-Content
| Type | Earning Potential | Main Challenge |
|---|---|---|
| Genre fiction (romance, thrillers, fantasy) | Strongest, especially in series | Writing quickly and consistently |
| Nonfiction | Good in niches with clear problems | Needs real expertise and trust |
| Low-content (journals, planners, puzzles) | Low per book | Very crowded, easy to copy |
Red Flags in Kindle Publishing Courses
- Promises of passive income from a few quick books.
- High-ticket coaching that pushes you to fund ghostwriters and ads with credit.
- Income screenshots showing revenue, not profit after ad spend.
- Pressure to buy on a sales call.
The FTC has taken action against a publishing course company over income claims; our Audiobook Income Academy review covers that case. For more warning signs, see our guide on how to spot make-money-online scams.
How to Give Yourself the Best Chance
- Pick a genre or niche you enjoy and readers actively buy.
- Study the bestsellers in that category: covers, titles, length and price.
- Write a book that genuinely serves those readers, ideally the first in a series.
- Invest in a professional-looking cover and careful editing.
- Decide whether KDP Select and Kindle Unlimited suit your book.
- Build an email list of readers so you're not dependent on ads.
- Publish consistently, and learn from each launch.
Is Kindle Publishing Worth It for You?
It's worth it if you enjoy writing, can publish consistently and are patient. It's free to start, and a good series can earn for years. It's not a fast or passive income source, and paying thousands for a course or ghostwriters before you've published anything is a risky way to begin.
