> The average royalty is about $25,000 a year for a course > A Great Courses lecturer earns a royalty that varies according to how highly viewers rate his performance; the base royalty is 4 percent of the course’s gross revenue, but that rate can rise to 6 percent if a course receives high enough evaluations. 25k being 6%, would mean the average course has gross revenue of about 416K per year.
