KENP royalty calculator
Turn Kindle Unlimited page reads into dollars.

What is KENP?
KENP (Kindle Edition Normalized Page Count) is Amazon's standardized page count for Kindle Unlimited royalties. It normalizes page counts across all books regardless of font size or formatting.
Recent US rates have ranged from about $0.0042 to $0.0049 per page read (May 2026: ~$0.00489). The rate changes every month based on the KDP Select Global Fund.

How the KENP royalty formula works (July 2026)
The math itself is trivial — the uncertainty lives in the rate, which Amazon only reveals after each month closes. That is why the calculator treats the rate as an input with a recent default rather than a constant:
KU earnings = KENP pages read × per-page rate
Per-page rate ≈ monthly Global Fund ÷ total pages read (per marketplace)
Full-read value = your book's KENPC × per-page rate
Example 1: a hobby month
10,000 pages read at $0.0048 = $48. That is roughly 33 complete reads of a 300-KENP novel — a realistic early month for a debut in KU.
Example 2: a working catalog
100,000 pages read at $0.0048 = $480 per month. Series authors hit this by keeping readers moving to the next book, not from one title alone.
Example 3: borrow vs sale
A 300-KENP book read fully earns about $1.47 (May 2026 rate). The same book sold at $2.99 pays $1.99 at 70% — so a borrow is worth roughly three quarters of a sale.
How the KDP Select Global Fund sets the rate
Every KU borrow is paid from one shared pot. Amazon announces the fund after each month — its own KDP site showed $70.3 million for May 2026 and $67.0 million for June 2026 in total KDP Select author earnings — and divides it by the pages read across all enrolled titles. More reading in a month dilutes the rate; a bigger fund raises it. That push-pull is why the US rate has oscillated between about $0.0042 and $0.0050 over the past year rather than trending in one direction, and why serious KU authors track the announcements (Written Word Media maintains the longest-running public list) instead of assuming last month's rate.
KENPC: how Amazon counts your pages
You are not paid on your print page count. Kindle Edition Normalized Page Count (KENPC v3.0) re-measures every book with standardized font, line spacing and layout settings so a page means the same thing in every title. A 250-page paperback might be 320 KENP; a dialogue-heavy novel often normalizes higher. Formatting tricks do not move it — KENPC is calculated from content, and Amazon caps what a single customer can generate per title. Find your number in the KDP Bookshelf's Select info panel, then multiply by the current rate to price a full read-through.
Is Kindle Unlimited worth it for your book?
KU rewards books that get finished and series that get binged. If your 300-KENP novel gets read to the end, each borrow is worth about three quarters of a $2.99 sale — and borrows convert far more easily than purchases, especially for new authors. The cost is 90-day digital exclusivity to Amazon: no Kobo, Apple Books or direct sales while enrolled. Nonfiction that readers dip into rather than finish, and authors with real traction on other stores, often earn more wide. Run your own numbers each enrollment period, and remember the print and audio editions stay free to distribute anywhere either way.
FAQ
Kindle Unlimited earnings questions, answered
How much does Kindle Unlimited pay per page read in 2026?
Amazon does not publish a fixed rate — it changes every month. Independent trackers such as Written Word Media calculated US rates between roughly $0.0042 (January 2026) and $0.00489 (May 2026) over the first half of 2026, consistent with the $0.004–$0.005 band of recent years. That is about $0.42–$0.49 per 100 pages read.
How is the KENP rate actually determined?
Each month Amazon announces the KDP Select Global Fund, then divides it across all KENP pages read worldwide that month. Your earnings are pages read × that month’s per-page rate for each marketplace. Because both the fund and total reading change monthly, the rate is only knowable in arrears — around the 15th of the following month.
What is the KDP Select Global Fund right now?
Amazon’s own KDP site reported $67.0 million in total KDP Select author earnings for June 2026 and $70.3 million for May 2026 (figures that include All-Star bonuses). Fund trackers list the May 2026 base fund at $66.9 million. For context, the fund was around $49–53 million per month in 2023–2024.
What is KENPC (Kindle Edition Normalized Page Count)?
KENPC is Amazon’s standardized page count, currently version 3.0, which normalizes font, spacing and formatting differences so every book is measured with the same yardstick. Your book’s KENPC often differs from its print page count — sometimes by 30–50% — and you can find it on the KDP Select info panel for each enrolled title.
Where do I see my KENP pages read?
In your KDP Reports dashboard under “KENP Read.” Amazon reports pages read daily per marketplace and per title. Multiply a month’s total by the announced rate for that month and marketplace to reconstruct your Kindle Unlimited payout — the calculator on this page does that math for you.
How much does a full read-through of my book earn?
Multiply your KENPC by the current rate. A 300-KENP novel read cover to cover earns about $1.47 at May 2026’s ~$0.00489 rate; a 600-KENP epic earns about $2.93. Compare that with the same book’s sale royalty — a $2.99 ebook pays $1.99 at 70% — to judge what a borrow is worth to you.
Do I get paid if someone borrows my book but never opens it?
No. Kindle Unlimited pays only for pages actually read, as measured by Amazon. A borrow that sits unread earns nothing, and there is no per-borrow fee. That is why KU strategy centers on books that get finished: series fiction, bingeable genres and strong openings.
Do re-reads count toward KENP?
Amazon pays for the first time each customer reads a page of your title. If the same subscriber re-reads your book next year, those pages are not counted again. Fresh borrows from new readers are what keep KENP income flowing month to month.
Does Kindle Unlimited require exclusivity?
Yes. KU enrollment happens through KDP Select, which requires the digital edition to be exclusive to Amazon for rolling 90-day periods. You cannot sell the ebook on Kobo, Apple Books, your own site or anywhere else while enrolled. Print and audio editions are not affected by the exclusivity requirement.
Is KDP Select worth it compared to selling wide?
It depends on your genre and audience. Binge-read genres (romance, LitRPG, thrillers) often earn more from page reads than they lose in other stores. Slow-burn nonfiction with strong non-Amazon audiences frequently does better wide. Model both: expected borrows × full-read value versus your realistic sales on other platforms — then review at each 90-day renewal.
What are KDP Select All-Star bonuses?
On top of the per-page fund, Amazon pays monthly All-Star bonuses to the most-read authors and titles in each marketplace. They are announced in KDP’s terms, paid automatically, and materially matter only at very high read volumes — treat them as upside, not as part of your plan.
Is the KENP rate the same in every country?
No. Each Amazon marketplace has its own per-page rate paid from the shared Global Fund, and they differ meaningfully — the figures cited on this page are US rates, which most trackers report. Your KDP payment report breaks out KENP royalties by marketplace so you can compute each store’s effective rate.
