Average Earnout. The term earnout indicates the total amount of money an author makes on a book, including both the advance and royalties. According to American Writers and Artists Inc., the average earnout for romance novelists ranges between $1,200 to $26,000, depending on the publishing house.
Using that, and the PW numbers, we come out that a handful of bestselling self-published authors will hit 300,000 copies per year, per title. Maybe a hundred of the rest will hit 30,000. They're usually publishing their books at about $4.99 per copy. And they get 70% of that, or $3.50.
