Quick Answer: On Amazon Kindle Direct Publishing (KDP), paperback author royalties for sales on Amazon marketplaces equal 60% of your retail list price minus printing costs. For expanded distribution to bookstores and libraries, the royalty rate drops to 40% minus printing costs. On a 250-page black-and-white paperback priced at $14.99, KDP printing costs are $4.00 ($1.00 fixed base + $0.012 × 250 pages), yielding a net author profit of $4.99 per sale (33.3% net margin).

How Amazon KDP Royalties Work: The Mathematical Formula
Kindle Direct Publishing operates on an automated print-on-demand (POD) model. When a reader orders your paperback or hardcover on Amazon, Amazon prints the single copy, binds it, ships it via Prime delivery, and deducts the exact manufacturing fee directly from your royalty share before depositing your net earnings.
The official Amazon KDP royalty formula for physical books is structured as follows:
- Amazon Distribution (60%): Sales occurring directly on Amazon.com, Amazon.co.uk, Amazon.de, and other official Amazon storefronts.
- Expanded Distribution (40%): Sales fulfilled through third-party wholesalers, academic libraries, and brick-and-mortar bookstores (Ingram, Barnes & Noble catalog).
2026 Amazon KDP Printing Cost Slabs
Printing fees depend on three variables: format (paperback vs. hardcover), ink & paper type (black & white, standard color, premium color), and trim size:
| Format & Ink Type | Trim Size | Fixed Base Cost ($) | Per-Page Rate ($) | 150-Page Print Cost |
|---|---|---|---|---|
| Paperback: Black & White | Standard (up to 6.12"×9.25") | $1.00 | $0.012 | $2.80 |
| Paperback: Black & White | Large / Oversized | $1.00 | $0.014 | $3.10 |
| Paperback: Standard Color | Standard | $1.00 | $0.027 | $5.05 |
| Paperback: Premium Color | Standard | $1.00 | $0.070 | $11.50 |
| Hardcover: Black & White | Standard | $6.25 | $0.012 | $8.05 |
Calculating Your Minimum Breakeven List Price
Amazon requires that your retail list price generates at least $0.00 in author royalties. Because royalties equal 60% of list price minus print costs, the formula to calculate your absolute minimum retail price is:
Minimum List Price (Expanded 40%) = Printing Cost / 0.40
For a 200-page black-and-white paperback with a $3.40 printing cost, your minimum list price on Amazon is $5.67. If you want to enable Expanded Distribution, your minimum list price rises to $8.50.
