Pricing your book wrong on Amazon can cost you thousands in lost revenue, but most authors just guess at their numbers. The Amazon Book Royalties Calculator takes the guesswork out of book pricing by showing you exactly what you'll earn from Kindle eBooks, paperbacks, and hardcovers at different price points. You simply plug in your book details and target price, and it calculates your potential royalties across Amazon's various formats and royalty structures. This free tool is particularly valuable for indie authors and publishers who need to make data-driven pricing decisions before they hit publish.
