Besides Rowling’s earnings from her books, she also gets an undisclosed sum from the profits of made out of Harry Potter films which have gone on to be huge hits at the box office. Rowling further pockets an estimated 100 million pounds from toy merchandise based on the characters from Harry Potter series besides taking home the profits from the video games and the Potter images that appear on every surface from sticking plasters to sweets. According to an estimate the Harry Potter brand is currently worth 7 billion pounds or $15 billion USD.
