Mike Tyson — $10 Million

Retired professional boxer Mike Tyson was dubbed the world’s undisputed heavyweight champion in the late ’80s. As of writing, he has a net worth of $10 million. During his heyday, however, he was one of the world’s most famous and highest-paid athletes. ESPN described him as “The Hardest Hitter” in heavyweight history, while Sky Sports considered him “the most ferocious fighter” to step foot on the professional boxing ring. He was also named the youngest boxing champion in sports history at age 20. During his career, Tyson earned nearly $430 million in endorsements, which is roughly $700 million nowadays after adjusting for inflation.

Unfortunately, the retired boxer faced personal issues over the years that cost him a fortune. Still, he was able to do some investment planning and earned a little money from his work in the entertainment scene, landing minor roles in film and television.
