Taylor Swift became a billionaire when Forbes included her on the list of the richest stars in 2024, thanks to her universally popular music and catchy lyrics. Despite starting her career as a singer who wrote songs about wealthy ex-boyfriends, Swift's rise in the music industry has been remarkable. While she has amassed an incredible amount of wealth, Jay-Z and Rihanna have higher net worths. However, Swift is the only musician to reach billionaire status primarily through her music income, particularly from her successful Eras tour.
