Royalty cliff
Also called: $9.99 royalty cliff, KDP royalty tier
Definition
The royalty cliff is the discrete drop in royalty rate when a KDP paperback is priced outside the $2.99 to $9.99 standard distribution band. At $9.99 a standard-distribution paperback earns 60% royalty minus print cost. At $10.00+ the rate stays 60% on standard but the publisher loses access to certain promo tools and faces buyer resistance.
What is the KDP royalty cliff?
The royalty cliff is the sharp change in effective royalty math at certain price points on KDP. The most-discussed cliff is at $9.99: a coloring book priced at $9.99 earns a 60% royalty in standard distribution, minus print cost, leaving roughly $3.69 to $4.30 per copy depending on page count. Pricing at $10.00 or above keeps the 60% standard royalty rate but moves the listing out of the "under $10" psychological band.
Is there a 35% versus 60% royalty cliff?
For paperback KDP, the royalty rate is a flat 60% in standard distribution between $2.99 and the upper limit, and a flat 40% in expanded distribution. Kindle eBooks have a 35% to 70% royalty split with stricter price-band rules, but that does not apply to physical coloring books.
Where exactly does the cliff bite for coloring books?
The cliff bites at $9.99 because buyer demand drops sharply above $9.99 on adult coloring books. Books at $9.99 sell at the conversion rate the category expects; books at $10.99 to $12.99 convert noticeably worse despite earning more per copy. The break-even price is niche- and page-count-dependent.
How do publishers price around the cliff?
The dominant pattern: price the book at $7.99 to $9.99 for the main format, keep print cost low by choosing 60 to 80 pages, and add a hardcover edition at $14.99 to $19.99 for buyers willing to pay more. Two SKUs at two price tiers beats one SKU pinned to either the cliff or above it.

Expanded distribution
Expanded distribution is an opt-in KDP setting that pushes a paperback into bookstores, libraries, and online retailers beyond Amazon (Barnes & Noble, Ingram-served chains). Royalty drops from 60% to 40% on expanded sales, and the publisher must list the book at a high enough price to clear print cost at the lower royalty.
KDP Select
KDP Select is an opt-in 90-day exclusivity program for Kindle eBook titles. Enrolled eBooks join Kindle Unlimited, earn page-read royalties, and get access to Kindle Countdown Deals and Free Promotions.

Low-content book
A low-content book is a KDP-published book whose interior is mostly empty or templated, such as journals, planners, logs, and coloring books. Pages are not blank but carry minimal author-written content. KDP allows low-content books with a separate dashboard since 2018.
