How Kindle Unlimited pays
Each month Amazon sets the size of the KDP Select Global Fund and divides it by all the KENP pages read that month. The result is the per-page rate, and every author in the marketplace is paid that rate for their pages. Because both the fund and total pages move, the rate shifts month to month, sometimes by 10% or more.
Worked example
A 400-page (KENPC) novel read in full earns 400 × $0.005365 = $2.15 at the September 2026 rate. 100,000 pages read in a month earns $536.50.
Why this matters for ads
Amazon's ACoS ignores page reads entirely. If you advertise a KU book, each borrow is worth a full read's royalty (or more, across a series) even though it never shows as a sale. Use the break-even ACoS calculator to see how far that moves your break-even, and the KENP rate history to see how much the rate swings.

What is KENP?
Kindle Edition Normalized Pages. Amazon counts pages read in Kindle Unlimited on a standard page size so that font settings and devices don't change the count, and pays authors per page read from the monthly KDP Select Global Fund.
How much does Kindle Unlimited pay per page?
It changes every month. The US rate for September 2026 was $0.005365 per page, about $5.37 per 1,000 pages. See the full monthly history on the KENP rate page.
Where do I find my book's KENPC?
In your KDP Bookshelf: open the book's Promote and Advertise page. KENPC is the KENP page count of the whole book; a full read pays KENPC × the rate.
Is the KENP rate the same in every marketplace?
No. Amazon sets rates per marketplace and some differ from the US rate. The figures here are US rates; check your KDP reports for other stores.
