In the United States, Mafia debuted in sixth place on the NPD Group's weekly sales rankings for computer games, a position it held for another two weeks. It was absent from the weekly charts after four weeks. Ultimately, it was NPD's ninth-best-selling computer game of September 2002. In the United Kingdom, the computer version of Mafia received a "Silver" sales award from the Entertainment and Leisure Software Publishers Association (ELSPA), for sales of at least 100,000 copies.
