How much do middle grade authors make?

The amount of money that middle grade authors make can vary widely, depending on factors such as the popularity of their books, the number of books they have published, and the terms of their publishing contracts. According to the Association of Authors' Representatives, the average advance for a middle grade book (a book aimed at readers aged 8 to 12) is around $5,000 to $15,000. However, it is worth noting that advances can vary significantly depending on the individual author and the publisher. Some middle grade authors may earn more or less than this amount. In addition to advances, middle grade authors may also earn royalties, which are a percentage of the sales of their books. The size of the royalty will depend on the terms of the author's publishing contract and the sales of the book. It is worth noting that many middle grade authors also earn income from other sources, such as speaking engagements, writing workshops, and other writing projects.
