Project your Kindle Unlimited revenue using real 2026 page-read rates. Accurate model accounting for KENPv2 normalization, read-through rates, and monthly borrow volume.
Print-equivalent page count for the book. A 250-page novel typically normalizes to ~275 KENP.
Kindle Unlimited subscribers who download this title per month.
Typical: 60% for genre fiction, 45% for non-fiction. What % of pages an average reader actually reads.
Historical range $0.0038–$0.0052 in 2026. Default $0.0045 reflects the 12-month moving average.
KENPv2 normalizes page counts. 1.1 is a reasonable default; verify via your KDP Reports after first sales.
Kindle Unlimited (KU) is Amazon's subscription reading service, and it pays authors on a fundamentally different model than direct sales. Instead of a per-unit royalty, KU authors earn a fraction of a cent per page read — times the number of readers who borrow the book times the percentage of pages they read.
The math comes from the KDP Select Global Fund, a monthly pool Amazon divides among all KU-enrolled titles based on pages read. In 2026, this has produced a per-page rate fluctuating between roughly $0.0038 and $0.0052. Default $0.0045 is a reasonable projection number.
"KENPv2" is Amazon's normalized page count — it's not exactly your manuscript's page count. Amazon normalizes for font, spacing, and margins so that a book can't game the system by shrinking type. Typical normalization ratio: 1.0–1.3× your manuscript page count depending on layout. Your exact KENP appears in KDP Reports once a book has borrows.
If 100 readers borrow your book but only finish 50% of it on average, you earn half the maximum possible revenue. Great first chapters, tight pacing, strong cliffhangers — these directly translate to KU dollars because they keep readers turning pages. Indie fiction authors who hit 70%+ read-through routinely earn 2–3× what authors at 40% earn for identical catalog size.
KU revenue compounds across catalog depth. A reader who borrows book 1 often borrows books 2, 3, and 4 in the same series. That series read-through is where the real KU income lives — indie authors earning $5k–$50k/month on KU almost universally have 10+ books in active series, published at a 6–12 books/year cadence.

KENPv2 is Amazon's normalized page count for Kindle Unlimited — their internal measure used to calculate page-read revenue fairly across books with different formatting. KENP is typically 1.0–1.3× your manuscript page count, depending on font size, margins, and line spacing. Your exact KENP appears in KDP Reports once the book has sales.
The per-page rate fluctuates monthly based on how many total pages are read across KU and the size of the KDP Select Global Fund. In 2026, it ranges from $0.0038 to $0.0052 per page, with a 12-month moving average near $0.0045. Amazon publishes the exact rate each month in KDP's payment emails.
Industry benchmarks: genre fiction (romance, cozy mystery, urban fantasy) averages 60–75% read-through. Non-fiction averages 35–55%. Thrillers and page-turners can hit 80%+. If your read-through is below 40%, first pages aren't hooking readers — not a KU economics issue, it's a craft issue.
First month for a new unknown author with no promotion: 10–50 borrows. First month with a BookBub Featured Deal or similar launch push: 500–3,000 borrows. Steady-state for a mid-tier indie: 50–200 borrows/month per book. Prolific series authors often hit 1,000–5,000 borrows/month per title after catalog compounding.
Yes. KDP Select is the exclusivity program that enrolls your book in Kindle Unlimited. Select requires 90-day Amazon exclusivity per book — you can't sell the same title on Gumroad, Apple Books, or your own site during that period. For KU-native genres (romance, cozy mystery, urban fantasy, paranormal), Select is almost always the right call.
Yes — this is how most Select-enrolled books earn. A title sold at $4.99 earns ~$3.40 per direct purchase (70% tier) AND page-read revenue when KU subscribers borrow it. The two revenue streams are separate and additive. Expect a rough 50/50 split for active titles in KU-friendly genres.
Three common reasons: (1) the per-page rate for the actual month was different from what you input, (2) your read-through rate is higher or lower than projected, (3) your KENP multiplier is different from the default 1.1 (check KDP Reports for your book's exact KENP). Once you have 1–2 months of real data, swap in your specific KENP and per-page rate for more accurate projections.
