Simon Cowell, 61, $600 Million

Famous for his strict, no-nonsense judging style on the several talent-search shows he has created, Simon Cowell is a massively successful television personality who has a bulging bank account to show for it. The music executive has been on the rise since his Pop Idol days, and he is currently one of the world’s highest-earning presenters.

Cowell doesn’t rely only on his television shows to sustain his family; he runs an entertainment company Syco, contributing to his wealth. While he is still active in showbiz, if the entrepreneur decided to retire, he would have a fun-filled downtime with his children’s financial future sorted out!
