How Kindle Unlimited pays authors

Kindle Unlimited readers pay a monthly subscription. Authors get paid from a shared monthly fund, by the page. Here's how it works and what it adds up to.

The short version

Your ebook must be enrolled in KDP Select (exclusive to Amazon for 90-day terms).
Each month Amazon sets the KDP Select Global Fund.
The fund is divided by every KENP page read across Kindle Unlimited that month to get the per-page rate.
You're paid your pages read × that rate.

What a reader is worth

At the September 2026 US rate of $0.005365 per page, a 300-page book read in full pays $1.61 and a 500-page book pays $2.68. For comparison, a $4.99 ebook sale at 70% pays $3.49. Long books often earn more per KU read than per sale.

The rate has stayed in a band of about $0.0040 to $0.0058 since 2015. Month to month it often moves 5-10%, so the same readership can pay noticeably different amounts.

Why series do best in KU

Subscribers don't pay per book, so trying the next one costs them nothing. Strong series tend to see high read-through in KU, and every later book read pays again. That's why many series authors find KU income outgrows sales. Measure yours with the read-through calculator.

Should you be in KU?

It's a trade: page-read income and Select promotions in exchange for ebook exclusivity. Run your own numbers in the KDP Select vs wide calculator, or read is KDP Select worth it?
