We base the calculation of your share of the KDP Select Global Fund by how often Kindle Unlimited customers choose and read more than 10% of your book, and Kindle Owners' Lending Library customers download your book. We compare these numbers to how often all participating KDP Select titles were chosen. For example, if the monthly global fund amount is $1,000,000, all participating KDP titles were read 300,000 times, and customers read your book 1,500 times, you will earn 0.5% (1,500/300,000 = 0.5%), or $5,000 for that month.
