This is a difficult question to answer because it varies so much depending on the editor, the project, the level of editing required, and other factors. It is important to discuss your budget with the editor upfront so that you can make sure you are both on the same page. Generally speaking, you can expect to pay anywhere from $0.015 to $0.035 per word for editing services. So, for a 80,000-word novel, you could be looking at a bill anywhere from $1,200 to $2,800. Of course, this is just a general range, and your actual costs could be higher or lower depending on the factors mentioned above.
