At 84, Palmer has a net worth of around $675 million. His endorsements include Callaway, Ketel One, and Rolex. The Arnold Palmer Design Company has created hundreds of golf courses and Palmer himself owns Latrobe Country Club in his Pennsylvania hometown and Bay Hill Club and Lodge in Orlando. There's also Arnold Palmer Motors, Arnold Palmer's Restaurant, Arnold Palmer Hospital for Children, and Arnold Palmer Prostate Center

Palmer credits his success to a strategy he developed with Mark McCormack, his agent and business partner. Unlike other athletes, Palmer avoided endorsements based on recent on-course triumphs because he knew that he would eventually start losing and he wanted to have a more sustainable career. McCormack dealt exclusively with companies interested in Palmer's personality and lifestyle. He embodied the idea of being a winner by not talking about winning.

"He was the first golfer the American public truly cared about," Thomas Hauser wrote in the preface to 'Arnold Palmer: A Personal Journey.' And Arnie was never bashful about parlaying his fame into profits or putting his name on a product. That said, he doesn't receive royalties when you mix lemonade and ice tea.

Estimated Net Worth: $675 million
