We were first introduced to Simon Cowell as the snarky, brutally honest judge on American Idol, but he has done a lot more than just that — and all of his successes reeled him in quite a huge fortune. The TV personality has a stunning net worth of about $600 million and it’s all thanks to his hard-working attitude, according to Celebrity Net Worth,

When Simon was younger, he worked in the mailroom at EMI Music Publishing, where his father, Eric, was an executive. After spending a few years there, the entrepreneur left EMI and formed his own label, E&S Music, in the early 1980s. The company went under in 1989 and Simon was forced to sell his business. Although it was a dark time in the record executive’s life, Simon later went on to start another label called S-Records.

By working with actors Robson Green and Jerome Flynn, who signed with him and recorded the hit song “Unchained Melody,” Simon made his first million by age 40. However, the dad of one didn’t reach superstardom until he became a judge on American Idol in 2002. After he left the show in 2010, Simon resided on the judge’s panel on numerous reality shows, including The X FactorBritain’s Got Talent and America’s Got Talent.

The doting dad also produced various programs including American Inventor and Celebrity Duets. Aside from having huge success in the TV world, Simon, of course, was first and foremost all about music. The A-lister signed notable bands over the years — which added to his fortune. Music acts like Five, Westlife, One Direction and Fifth Harmony have all reached great heights under his watchful eye.

While the famous TV star has hundreds of millions of dollars to his name, he is said to bring in about $95 million a year, so it’s clear his fortune won’t be winding down anytime soon. In fact, Simon already has someone in mind who will be the perfect person to take over his incredible empire: his son, Eric.

“He’s in training … I’m getting him ready to do my job,” Simon told Lizzie Cundy on the UK morning show This Morning. Well, little Eric sure is going to see a lot of green in his life!
