How to calculate the cost of writing a novel with a book flag?

The book flag novel adopts the author signing system, and the signing fee with the author is evaluated according to the quality of the work and the market demand, generally starting from 1 10,000 yuan. There is no remuneration for the signed works in the first three months. After three months, it will be settled by monthly remuneration. The remuneration standard is 60% of the sales revenue of the works * * The platform will charge the remaining 40% of the service fee. For novice authors, Shu Qi's novels also offer a "novice signing award" policy. Depending on the quality of their works and the amount of reading, they may get awards from 300 yuan, 500 yuan or 700 yuan. It should be noted that the remuneration of the signed works will only be generated if the works have a certain popularity and sales revenue, and the platform will settle the author on 15 every month.
