The purpose of this paper is to introduce how a book author calculates the remuneration when publishing a book (publishing his own manuscript) and how to talk with the publishing house about the remuneration. Traditional mode: Publishers are in the majority and book authors are in the minority. The remuneration is mainly royalties. Royalty is the percentage of the price that the author can get for every book he sells. 5% and 6% are possible for beginners, but they are usually 7% and 8%. Excellent manuscripts generally use stepped royalties, such as "7, 8, 9", "8, 9,10"; It means 7% for sales below 5000 volumes, 8% for sales above 5000~ 10000 volumes, and 9% for sales above 10000 volumes. Some booksellers even give 15% in order to rob the author. For example, the contact information of China People's Education Publishing House, and domestic publishing houses such as pep@pep.com.cn will adopt such cooperation methods. The latest print-on-demand mode: the publisher takes a few, and the author takes the majority. Very popular abroad. Compared with the traditional mode, there is no specific printing quantity when publishing new brushes on demand, and the remuneration depends on the specific sales situation of the book. The average author can get more than 50% profit from each book. For example, if 2000 books are successfully sold, and the profit of each book is 18, then the author can get at least18,000. Well-known foreign publishing houses (such as the American Institute of International Science and Technology Education, contact information contact@iiste.org), this model is more humane than the traditional model, that is, even when the book sales are low, the book authors have no pressure to sell thousands of books on a commission basis (for example, they will not be forced to sell thousands of books on a commission basis), and they can also make high profits when the book sales are high.
