A big question for many authors is how to determine the retail price of their book. In some businesses, conventional wisdom says to set the price of a product by at least doubling your cost. Since that’s the case, if it cost you $10 to print your 150-page book, you should charge $20, right? Wrong! The book industry is not conventional, and the conventional wisdom thus does not apply.
There are many different factors that impact the price of your book: genre, page count, binding (hardcover/paperback), and competition all dictate the best price for the retail market.
