Pricing & Royalty Structures
KDP's royalty structure isn't a single number — it's a set of tiers and options with real tradeoffs, and paperback royalties work on a genuinely different mechanic from e-book royalties. Getting this wrong is a common way a book quietly earns far less per sale than the author expected.
E-book Royalty Tiers
| Tier | Royalty | Typical Requirements |
|---|---|---|
| 35% option | 35% of list price | Available at any price point, no restrictions |
| 70% option | 70% of list price, minus a delivery fee based on file size | Only available within a specific price band (roughly $2.99–$9.99 in most marketplaces) and other eligibility rules |
The 70% tier's own delivery fee matters more for image-heavy books (like low-content interiors) than for plain-text narrative manuscripts, since file size scales with images — it's worth checking the actual fee against your specific file before assuming the full 70% applies.
Paperback Royalties Work Differently
A paperback's royalty is roughly: list price, minus the printing cost, minus a percentage taken by KDP. Printing cost itself scales directly with page count and trim size — a longer book or a larger page size costs more to print, which eats directly into the per-unit margin. This is the same page-count dependency Chapters 5 and 6 already flagged for formatting and cover spine width, showing up again here in pricing.
Pricing Low-Content vs. Narrative Differently
Low-Content Books
Typically priced lower per unit — buyers expect a modest price for a mostly-template product. For paperback, watch the printing-cost floor closely, especially at larger trim sizes or higher page counts, since it can eat a large share of a low list price.
Narrative Books
More pricing flexibility, especially for the e-book edition. A well-reviewed, well-positioned narrative title can sustain a higher price than a low-content book of the same page count.
Kindle Unlimited & Page-Read Royalties
Enrolling a book in KDP Select makes it exclusive to Amazon, but eligible for Kindle Unlimited — instead of a per-sale royalty, KU pays a per-page-read royalty from a monthly fund shared across every enrolled book. This is a genuinely different income model, and it matters far more for narrative books (where readers actually read through many pages) than for low-content books (which typically have very little "read-through" behavior to earn KENP royalties from at all).
