Kindle Unlimited
Kindle Unlimited (KU) is Amazon's subscription reading service, and for many genres it is the majority of an indie author's income. This hub collects our coverage of how KU actually pays — the KENP per-page rate, the monthly Global Fund, the 3,000-page cap per borrow — and the strategic trade-off at its center: digital exclusivity through KDP Select in exchange for page-read revenue and promo tools. We treat KU numerically and skeptically, because the payout floats and Amazon changes the rules quietly.

Frequently asked
How much does Kindle Unlimited pay per page in 2026?
The KENP per-page rate floats because it is the monthly Global Fund divided by all pages read. It averaged around $0.00445 in 2025 and sat near $0.004888 in May 2026, generally moving between $0.0040 and $0.0050. A fully read 300-page novel therefore earns roughly $1.30 to $1.35. Because the rate is never guaranteed, model your income at a $0.004 floor rather than the high end.
Is Kindle Unlimited worth it for authors?
It depends on your genre. In romance, LitRPG, cozy mystery, and much of genre fiction, 70% to 80% of top titles carry KU badges and page reads are the majority of high earners' income, so exclusivity pays. In most nonfiction, children's, and reference categories, readers buy rather than borrow and completion is low, so wide distribution usually earns more. Count KU badges in the top 100 of your primary sub-category: about 70-plus favors enrolling, 30 or fewer makes wide viable.
What is the KDP Select Global Fund?
The Global Fund is the monthly pool Amazon sets aside to pay KDP Select authors for Kindle Unlimited and Kindle Owners' Lending Library page reads. It reached $66.9 million in May 2026, up roughly 27-fold from its $2.5 million launch in July 2014. Despite that growth, per-page rates have stayed compressed because total pages read across the program grew even faster — so a bigger fund has not meant a bigger per-page payout.
