The average cost to produce a 30-second, national TV commercial in 1999 was $343,000—a 16 percent increase ($48,000) from the previous year—according to the American Association of Advertising Agencies (4A’s) ’99 Television Production Cost Survey. That’s the largest hike in the 13-year history of the annual 4A’s study. Significant increases were also reported in such areas as the average cost to edit and finish an original :30 (26 percent), sound recording and mixing costs (23 percent) and music (35 percent). At the same time, production company markup went down to an average of 25 percent, a one percent decline from the 4A’s ’98 figure.
