Editorial rates can be offered as per word, per page, hourly or flat rate per project. Rates generally fall within the ranges below, but each editor’s actual estimate will vary depending on the project, the level of expertise required, required deadlines, and other factors. To get a general idea of what editing for a particular project may cost, divide your word count by 250 (the number of words on a manuscript page formatted according to industry standards) and then multiply that by a mid-range dollar amount in the fee range shown.
