KENP Calculator for Kindle Unlimited Royalties

KENP stands for Kindle Edition Normalized Pages — Amazon's standard page unit, so that a payout does not depend on the font size a reader happens to use. Enrol an ebook in KDP Select and it becomes borrowable in Kindle Unlimited; you then earn a share of that month's KDP Select Global Fund as customers read your pages for the first time. Pages read, not borrows, is what pays: a borrow nobody opens earns nothing, and a customer re-reading pages they have already read does not pay for them twice.

KDP publishes how Kindle Unlimited pays: enrol an ebook in KDP Select and you earn a share of that month's KDP Select Global Fund as customers read your pages for the first time. Those pages are counted in Kindle Edition Normalized Pages, and Amazon derives that count from your uploaded file. What KDP does not publish is a per-page rate: the fund is announced, and the rate is what the fund worked out to, which every author reads off their own royalty report. So the rate here is a reading rather than a quotation, it is dated to the fund month it belongs to, and entering the figure from your own report replaces it. A rate with no month attached is not a rate — it is last year's rate.

Because that figure is authoritative for your account and ours is not. Amazon announces the fund; the per-page rate is what the fund worked out to, and every author reads it off their own royalty report in Reports › Prior Months' Royalties. Whenever you enter a rate, this calculator uses it and ignores anything on file — the rate table here is a fallback for planning, not an authority.

Pages read multiplied by that month's rate. If you have your KENP Read figure in front of you, enter it directly and the arithmetic needs no assumptions at all. If you are planning rather than reporting, estimate it as borrows multiplied by your book's KENP length multiplied by how far the average borrower gets — and note that the last of those three is a guess you are making, not data anyone publishes.

Amazon derives the real count from your uploaded file after publication, and it is shown on your KDP Bookshelf — use that number once your title is live. Before then, the estimate here works back from your word count, which is why it is shown as a range rather than a single figure. Layout matters more than length: a dialogue-heavy novel and a dense nonfiction book of the same word count come out at noticeably different normalized page counts, and a book of recipes or exercises further apart still.

Because words per normalized page is not a figure Amazon publishes, in any form. It is an estimate we derive, and the spread between densely-set running prose and short, dialogue-heavy paragraphs is real and wide. A single number here would be a guess wearing a calculator's clothing; the range is the honest shape of the answer, and the content-type selector is what narrows it.

That depends on where your readers are, and this page will not pretend otherwise. What it does is the arithmetic: it shows what one complete KU read-through pays against what one sale pays, how many full reads it takes to equal a purchase, and what a month looks like under each scenario using sales figures you supply for both. It models no uplift of its own for going wide, because inventing a multiplier would quietly answer the question you came here to ask. Exclusivity — KDP Select asks for the digital edition for a 90-day term — is a cost that does not appear in any of these numbers.

No. KDP Select and Kindle Unlimited cover the enrolled Kindle ebook; print editions are separate formats and are never borrowable. That is why the comparison on this page offers no print option — a paperback has no page-read income to compare against.

Amazon funds marketplaces separately, so a rate in pounds is a different figure from the US rate rather than a conversion of it. Where we hold no reading for a currency, this calculator says so and asks for yours instead of converting the US number and calling the result a rate. Refusing is the honest answer; a converted figure would look like data and be arithmetic on an unrelated fund.

The mechanism is: how Kindle Unlimited pays, what a normalized page is, and when the fund is announced all come from KDP's own help pages, which are linked and dated on this page. The per-page rate is not — Amazon publishes the fund, not a rate — so ours is a reading taken from KDP royalty reports for a named month, labelled as such wherever it appears. The sale royalty in the comparison comes from the same code the KDP Royalty Calculator runs. Nothing here is read from your KDP account.
