The Twilight star topped this year's Forbes list for best-paid actresses thanks to earnings from such blockbusters as Breaking Dawn Part 1 and Snow White and the Huntsman.
The 22-year-old has earned $12.5 million (£7.9m) for each of the five Twilight Saga films, as well as a cut of the earnings.
Between May 2011 and May 2012, Stewart has managed to make an estimated $34.5 million (£21.9m).
She beat out her Snow White and the Huntsman co-star Charlize Theron, who came in at number five on the annual list.
Stewart, who just wrapped Breaking Dawn Part 2, will also be seen this summer in the movie adaptation of Jack Kerouac's On the Road.
