Self-publishing through Amazon Kindle Direct Publishing (KDP) has rapidly become one of the most popular and profitable ways for independent authors to distribute their books globally. Whether you’re a first-time author, novelist, nonfiction writer, children’s book creator, or a low-content book publisher (like journals, planners, and workbooks), Amazon KDP provides a powerful self-publishing platform with a print-on-demand model. This model removes the need for large upfront investments in printing and inventory, making it accessible for writers aiming to publish a book, sell books online, and generate passive income from book sales while retaining creative control and higher royalty rates.
But while eBook publishing is virtually cost-free, printing physical books—paperbacks and hardcovers—does come with a cost. For indie authors, one of the most important questions is: How much does it cost to print a book on Amazon KDP?
The short answer is: it depends. Printing costs are influenced by your book’s trim size, page count, ink type, paper choice, and format (paperback or hardcover). Understanding these costs is critical because they directly affect your list price, royalty earnings, and profit margins.
In this comprehensive guide, we’ll break down exactly how KDP printing costs work, provide real-world cost examples, explain how royalties are calculated, and share tips to help you minimize expenses while maximizing profits.
📊 What Determines Amazon KDP Printing Costs?
Amazon uses a formula to calculate printing costs based on several book specifications. Let’s look at each factor in detail.
1. Trim Size
The trim size is the physical dimensions of your book. Common sizes include:
- 6” x 9” (most popular for novels)
- 5.5” x 8.5” (common for fiction and memoirs)
- 8.5” x 11” (often used for workbooks and textbooks)
- 8.5” x 8.5” (popular for children’s picture books)
📌 Rule of thumb: Larger books require more paper, so they cost more to print.
2. Page Count
The number of pages is one of the most important cost drivers. More pages = higher cost.
- Black-and-white interiors have a lower per-page rate.
- Color interiors have a higher per-page rate.
Even blank pages count toward your total page count, so careful formatting matters.
3. Ink Type
Amazon KDP offers three types of printing:
- Black ink on cream paper (common for novels and fiction)
- Black ink on white paper (often used for nonfiction and illustrated text-heavy books)
- Color ink on white paper (standard or premium—used for children’s books, cookbooks, photography, and art books)
📌 Tip: Color printing can be 2–3x more expensive than black and white.
4. Paper Type
- Cream paper is smoother, giving a traditional “novel feel.”
- White paper provides higher contrast, making it better for nonfiction, technical, or illustrated books.
Both options are priced similarly, but color printing always requires white paper.
5. Cover Type
- Paperback (softcover) → cheaper, faster to produce, most common for indie authors.
- Hardcover (case laminate) → more durable and premium-looking, but costs significantly more.
6. Marketplace
KDP printing costs vary slightly depending on where your book is printed and sold (US, UK, EU). While differences aren’t huge, they can affect royalties if you sell across multiple markets.

🧮 How Amazon Calculates Printing Costs
Amazon KDP calculates royalties using this formula:
Royalty = (List Price × Royalty Rate) – Printing Cost
- Paperback sales on Amazon: 60% royalty rate.
- Expanded distribution: 40% royalty rate.
👉 Example: If your book sells for $12.99 and printing costs $3.25:
Royalty = ($12.99 × 60%) – $3.25 = $4.54

📉 How Printing Costs Impact Royalties
Printing costs don’t just affect production—they directly impact your profits.
For example:
- A 250-page paperback novel costs ~$3.25 to print.
- A 40-page children’s book in premium color costs ~$6.75 to print.
If you set both at $12.99, the novel earns you ~$4.54 per sale, while the children’s book earns only ~$1–2.
📌 This is why authors must balance affordability for readers with profitability for themselves.
💡 Tips to Reduce Printing Costs
Here are proven ways to lower your expenses:
✅ Stick to black & white interiors unless color is absolutely necessary.
✅ Use standard trim sizes like 6” x 9” to avoid higher costs.
✅ Keep page count efficient by tightening formatting.

✅ Avoid unnecessary blank pages and wide margins.
These changes can save you $1–$3 per copy, which adds up over hundreds or thousands of sales.
