The 20 women on Forbes' Cash Queens list earned a combined $420 million between June 2006 and June 2007. The vast majority collected hefty paychecks from sell-out tours. To compile the list, Forbes examined concert grosses, merchandising revenue, album sales and additional revenue streams from ancillary businesses: clothing lines, fragrance deals and endorsements. Only "active" artists were considered--those who had released an album or film or toured during the specified period. These are gross income figures, with no deductions for taxes, management or agent fees.

Beyonce, who came in #5 on the list and #1 in female urban music, earned an estimated $27 million dollars in revenue, thanks to her album B’day, a world tour and various endorsement deals. Other notable names on the list include Mariah Carey ($13 million), and Jennifer Lopez ($6 million).
