Mariah Carey | Musician and Entrepreneur | $320 Million

Mariah Carey remains one of the best-selling artists in history, having sold over 200 million records worldwide. The artist also gets credit for having more chart-topping songs than any other female producer and songwriter in the US chart’s history. Even so, none of this probably wouldn’t have been possible if it weren’t for Mariah’s number-one supporter and teacher – her mother, Patricia Carey, a former opera singer and vocal coach. Along with receiving vocal lessons, the at-the-time aspiring singer also developed a knack for poetry and literature. Nowadays, thanks to her ever-improving talent, Mariah has earned quite a fortune. In fact, she can easily make $600,000 a year on royalties just for the song All I Want for Christmas Is You.

Even her least successful projects still make a bank. Just take her album Glitter, which sold 3 million copies. A small number for someone like her, but so much more than what the average could achieve these days.
