The 30-year-old socialite - who appears alongside her family in hit show `Keeping Up with the Kardashians` as well as starring with sister Kourtney in `Kourtney & Kim Take New York` - topped the list by US-based website The Daily Beast after earning $6 million in 2010.
Former `Hills` star Lauren Conrad came second, taking home $5 million, while Kim`s sisters Khloe and Kourtney also made the list after each earning $2.5 million.
Kim is said to earn up to $75,000 for a personal appearance and has made a fortune from endorsement deals, which include Skechers sneakers, Kotex tampons, as well as her own range of swimwear, jewellery and perfume.
The Daily Beast`s list measured those "who`ve cashed in on fame versus talent" and they only counted reality TV stars with a show that aired or was in production in 2010.
Other stars to make the list include former Playboy model Kendra Wilkinson, mother-of-eight Kate Gosselin, former `Real Housewives` star Bethenny Frankel and Audrina Patridge, who is working on her own programme, entitled `The Audrina Show`, after originally shooting to fame on `The Hills`.
