Experience with publishing books through Amazon KDP
Amazon offers a Kindle Direct Publishing (KDP) platform service that allows individuals to publish and sell books for free. Books published through this KDP will be sold simultaneously on Amazon sites in 13 countries.
I use this KDP (Kindle Direct Publishing) service to sell Kindle e-book and paperback. The books I have published have been selling an e-book vs. a paperback at a 3: 1 ratio.
Royalty in e-books can receive 70% of the book's price (if the e-book is priced below $ 9.9) and the paperback can receive 60% in royalties. In fact, the price of a paperback is 2.5 times higher than the price of an e-book. In other words, selling one paperback may be more profitable than selling two e-books. Book prices can be arbitrarily set by authors for both the e-book and the paperback. However, in the case of the e-book, the book price must be set at $ 2.99 to $ 9.99, so 70% of the book's price will be provided royalties, otherwise it will be set at 35%. (See chart below)
Book publishing through this KDP is sold through amazon.com, as well as amazon.uk, amazon.fr, amazon.co.jp, and Amazon service sites in 13 countries, including Canada and Brazil. In other words, it is sold in 13 countries with one publishing. Book royalties are paid in the currency of each country sold. Amazon KDP is open to anyone.
The chart on the left shows the ratio of sales by Amazon service country (8 countries), US 29.1%, Europe 23.6%, Japan 10.9%, and Amazon market size. It is just amazing to see how it is sold in other countries. Obviously, I just published my book on amazon.com, and I'm surprised that it's published in all of the countries that are served by amazon (13 countries).
The chart on the right is for those who have received the Kindle Unlimited (KU) service to view unlimited e-books. This revenue appears to be statistic at the end of each month by counting the number of pages KU subscribers read.
