KENP Earnings Estimator

Project your Kindle Unlimited revenue using real page-read rates. Accounts for KENPv2 normalization, read-through rates, and monthly borrow volume.

How Kindle Unlimited pays authors

Kindle Unlimited (KU) pays authors a fraction of a cent per page read — times the number of readers who borrow the book, times the percentage of pages they actually read. The math comes from the KDP Select Global Fund, a monthly pool Amazon divides among all KU-enrolled titles based on pages read.

"KENPv2" is Amazon's normalized page count — not exactly your manuscript's page count. Amazon normalizes for font, spacing, and margins so a book can't game the system by shrinking type. Your exact KENP appears in KDP Reports once a book has borrows.

Read-through rate matters enormously: if 100 readers borrow your book but only finish half of it on average, you earn half the maximum possible revenue. KU revenue also compounds across catalog depth — indie authors earning real money on KU almost always have 10+ books in an active series.
