Many readers are surprised to learn that the author's cut is quite low -- as a general rule, it ranges from 10 to 15 percent, though very popular authors are able to negotiate a higher royalty and others must accept a lower one. Flashy news items about handsome advances (for hardcover or paperback rights) paid to such young authors as Jonathan Safran Foer or Dave Eggers create the false impression that writing books is a lucrative enterprise. (Advances are an upfront payment made "against royalties"; the advance is deducted from the author's royalty payments as copies of the book are sold, although many high-profile -- and even low-profile -- books fail to "earn out" their advances.) Except for a handful of bestselling writers, the overwhelming majority of authors make only $5,000 or $10,000, if that, on projects that took them years to complete. (Most must rely on other sources of income, such as teaching, journalism or a gainfully employed spouse to get by.)
