KENP Explained: What It Is and What It Pays

KENP stands for Kindle Edition Normalized Pages: Amazon’s standard page count for a Kindle book, the same on every device and font size. KDP counts the KENP that Kindle+ (formerly Kindle Unlimited) subscribers read or listen to and pays authors for them from a monthly fund, at a rate that changes every month.

What KENP and KENPC mean

A Kindle book has no fixed pages: change the font size and the pages move. KENP is Amazon’s way around that. According to the KENP help page, KDP calculates it with standard formatting settings (font, line height and line spacing), so a book has one count whatever device or display settings the reader uses. KDP uses KENP to measure the pages customers read or listen to.

Counting starts at the Start Reading Location, the point where the book opens. Amazon typically sets it at chapter 1, so front matter before it does not count. Everything from there to the end of the book does: the text, the back matter, and non-text elements such as images, charts and graphs.

One book’s total is its KENPC, the Kindle Edition Normalized Page Count, and it is not your print page count. Before you upload, the word count to page count calculator gives a rough range; KDP calculates the real figure after upload.

Who earns from KENP: KDP Select and Kindle+

Kindle+ is the new name of Kindle Unlimited. KDP announced the change on October 22, 2026, together with a second one: audiobooks, including KDP audiobooks with virtual voice and ACX audiobooks that can now be enrolled in KDP Select, are part of the subscription for customers on Amazon.com. KDP says the subscription has grown to include millions of eBooks, audiobooks, magazines and comics, and it wanted a name that reflects that. From here on, this guide says Kindle+.

Only titles enrolled in KDP Select are in Kindle+, and enrollment adds them automatically. An audiobook with virtual voice joins when its eBook is enrolled, and eligible ACX audiobooks can be enrolled from the Bookshelf. Select runs in 90-day termsthat renew on their own unless you turn renewal off. You can cancel within three days of a term’s start; later, turning off renewal takes the book out at the end of the term.

The price is exclusivity. For the length of a term the Kindle eBook can be distributed only through KDP and public libraries, though print, video and other formats of the title can still be sold elsewhere.

Select pays in two ways. Pages read and listened to are paid from the fund. On top of them, the KDP Select bonusis a discretionary monthly bonus for eBooks only; the Prior Months’ Royalties report calls it the All Stars Bonus.

Leaving does not stop pages at once. Readers who borrowed the book can keep reading it after your enrollment ends, and KDP says you earn a share of the fund for pages read after the end date.

The KDP Select Global Fund and the KENP rate

Kindle+ royalties are paid from the KDP Select Global Fund. KDP reviews its size each month and announces it in the KDP Community forum near the 15th of the following month: the September fund, for example, is announced around October 15. What you earn is your share of the pages read, not the number of times your book was borrowed.

Listening comes out of the same fund. KDP says reading continues to be paid by page as before and that listening is paid the same way, by page, with funds added to the KDP Select Global Fund for the new listening activity. It also says it will evolve the fund to reflect the differences between reading and listening as it learns how customers use both.

The per-page figure is the KENP rate, and KDP’s definition is one line: the fund amount for a marketplace divided by the total KENP read in that marketplace that month. Your income is then your KENP read times that rate.

Here is the division with made-up round numbers. Say one marketplace’s fund is $2,000,000 for the month and subscribers read 400 million KENP there. The rate is $2,000,000 ÷ 400,000,000 = $0.005 per KENP. A 300-KENP novel that 120 subscribers read to the end adds up to 36,000 KENP, which pays $180.

Two details are easy to miss. First, the rate is per marketplace. KDP says each country’s share of the fund varies with exchange rates, reading and listening behavior and local subscription prices, so pages read on Amazon.de pay at the German rate, in that store’s currency. Second, KDP’s help pages define the rate but never print it. Amazon announces the size of the fund; trackers work the per-page figure out from authors’ royalty reports.

How much Kindle+ (Kindle Unlimited) pays per page, and why it changes

With no official figure to quote, this guide uses the tracker behind the KENP calculator on this site: Written Word Media’s KDP Global Fund tracker. It follows KDP’s monthly fund announcements and works out the U.S. rate per KENP from authors’ royalty reports, so it is a tracker’s calculation, not an Amazon number. Between January 2025 and September 2026 it put the U.S. rate between about $0.0041 and $0.0054, and in most months between $0.0042 and $0.0052. The calculator starts from the middle of that range, $0.0047 for Amazon.com. At $0.0042 to $0.0052, one complete read of a 300-KENP book pays about $1.26 to $1.56.

The last three months show why you cannot read the rate off the size of the fund.

July’s fund was the largest in the tracker’s list, which starts in January 2025, yet its rate was the second-lowest of 2026. By September the fund was $1.7 million smaller and the rate was 27 percent higher. The formula explains it: a rate is a fund divided by pages read, so more pages read means less per page unless the fund grows with them. All of these months come before listening joined the subscription on October 22, 2026.

Two more things move your number from month to month:

• The marketplace. Each country has its own share of the fund and its own rate, in its own currency.
• The exchange rate. Royalties earned in another currency reach you at the rate on payment day, so what the Royalties Estimator shows will not match what you are paid.

KDP’s own advice for estimating is to use the KENP rate from the last announced fund, or adjust it up or down, and expect the real figure to differ. Once a month is final you can see the rate you actually got: divide a title’s Kindle+ royalties in Prior Months’ Royalties by its KENP for the same month and marketplace in the KENP report.

What counts as a page read

The rules are on KDP’s Royalties in Kindle+ page. The ones that matter most:

• First read only. KDP pays the first time a subscriber reads a given page. Reading it again, in the same format or another, is a re-read and does not pay.
• Pages, not borrows. Earnings are measured in KENP, so a borrow pays for the pages read, whether that is 12 or all 300.
• A cap per reader. You can earn at most 3,000 KENP per title per customer. It matters only for very long books and box sets: a 4,500-KENP box set read cover to cover pays for 3,000.
• Listening counts too.KENP measures pages listened to as well as read, and the KENP report shows Kindle+ pages read and Kindle+ pages listened separately. Audiobooks in Kindle+ are available to listeners in the U.S. today, with more marketplaces to come. When a reader reads and listens at the same time (Immersive Reading), you earn once, at the higher rate if the formats’ rates differ.
• No rewards for reading. KDP does not allow marketing that gives Kindle+ customers payment, gift certificates, bonus content, contest entries, discounts or other gifts in exchange for reading or listening, and says it monitors for manipulation.

Where to find KENP in your KDP reports

KENP appears in several reports at kdpreports.amazon.com, each on its own clock. The KDP Reports help page gives the timings; here they are for KENP only.

Follow one month through. Pages read in March show up in the Dashboard within a day or two. KDP announces March’s fund near April 15, and the KENP report and Prior Months’ Royalties update around then. The payout arrives about 60 days after March ends, which is around the end of May. Our guide to all nine KDP reports covers the rest of the reports the same way.

How to estimate your KENP income

For a month that has closed you do not need an estimate: the KENP report has the pages and Prior Months’ Royalties has the money. An estimate is for decisions ahead of time, such as whether to enroll a new book.

It is a chain of four numbers: the book’s KENPC, the share of it a typical reader gets through, the borrows per month and the rate per KENP. Take the KENP calculator’s starting values: a 350-KENP book, 100 borrows a month, readers finishing 75 percent on average and $0.0047 per KENP. One complete read is worth $1.65, an average read $1.23 and a month $123. That is 26,250 KENP read at just under half a cent each.

Two of those numbers swing the result most. Read-through is the first: at 40 percent the same book earns about $66 a month, not $123. The rate is the second. The same 26,250 KENP are worth about $110 at January 2026’s $0.004202 and about $141 at September’s $0.005365, without a single extra read.

The estimate leaves out the KDP Select bonus, exchange-rate changes before payment and next month’s rate, which nobody knows until the fund is announced. The calculator uses one rate per page and has no separate setting for listening, and its starting rates outside Amazon.com are rough guides, so type the rate from your own report. To set page-read income against sales, the KDP royalty calculator works out what the same book earns per eBook and print sale.

KENP and your Amazon Ads

Some readers an ad brings in borrow the book instead of buying it, and Amazon counts that separately from sales. KDP explains the difference on its Advertising for KDP books page: your Amazon Ads account shows the estimated KENP attributed to a Sponsored Products campaign, meaning pages read by Kindle+ subscribers who borrowed the book after clicking its ads. Sponsored Brands got the same kind of figures (attributed KENP read and estimated royalties) in December 2023. Three points from the same page keep the numbers straight:

• The ad sales figure does not include Kindle+ pages read.
• The estimated KENP royalties count only pages read within 14 days after an ad click. Your KDP reports also include pages from readers who found the book another way, so the two will not match.
• KDP recommends checking your actual earnings in your KDP reports. The ads figures are estimates.

Here is why it matters, with made-up numbers. A campaign spends $50, and the paid sales it drove earned you $32 in royalty. On paid sales alone that is an $18 loss. The same campaign shows 8,000 attributed KENP; at about half a cent a page that is roughly $40 more, so the campaign came out about $22 ahead, as an estimate until the rate is final.

That is the reason to judge a Kindle+ title against a break-even ACOS that counts page-read income, not only sales. Our Amazon Ads guide shows how to set the break-even from royalty, and the ACOS calculator does the arithmetic for one book. SelfPub Go’s analytics imports KENP from the KDP reports you download and shows it beside paid sales, book by book, with its dollar value worked out from the rate you set and marked as an estimate. The ads module scores ACOS against your actual royalty, KENP included.

Common KENP mistakes

• Counting borrows as income. Pages are paid, borrows are not. A book that is borrowed often and rarely finished earns little.
• Comparing the KENPC with print pages. The two are measured differently, so use the KENPC when you work out Kindle+ income.
• Treating early numbers as final. The Dashboard and the Royalties Estimator are provisional, and KDP says monthly KENP can change until it is final near the 15th.
• Using one rate everywhere.The rate changes every month and differs by marketplace. A tracker’s U.S. figure is a range to plan with, not Amazon’s number, and it says nothing about Germany or Japan.
• Reading the ads console as your Kindle+ income. It shows only click-attributed pages, and only as an estimate.

A short monthly routine

• Around the 15th:read the fund announcement, then open the KENP report and Prior Months’ Royalties for last month. Record the pages, the royalties and the rate you got in each marketplace. The Dashboard in between shows direction, not the final figure.
• Same day:put last month’s ad spend next to paid royalty and page-read income for each book, and update the rate in the KENP calculator.
• Before each KDP Select renewal: compare Kindle+ income with what the book could earn in other stores. Lever 7 of our royalty guide walks through that choice.

Names, timings and rules here come from KDP Help, the KDP Community and Amazon Ads as of the date at the top of the page; the rate figures come from Written Word Media’s tracker. Amazon changes these pages from time to time. If something no longer matches, the KENP help page and Royalties in Kindle+ are the sources to trust.
