Roger Federer has made a career of piling up records on court, but he’s also approaching some huge numbers off the court.

Forbes reports that the Swiss legend’s annual earnings, inclusive of prize money and sponsorships, have reached a career high of $93.4 million.

Federer upped both his tournament schedule and the amount of exhibitions he played in 2019, increasing his workload significantly.

Businessinsider.com adds that because of a shoe deal with Nike, an investment in running shoe firm On, and money received from exhibition tours, “Federer’s career on-and-off-court earnings are approaching $900 million, with $200 million more committed by sponsors.”

Should Federer become a billionaire, it would mark the first time an athlete who competes in the sport of tennis has surpassed the barrier.

It would also see the 20-time Grand Slam champion join other billionaire athletes including Michael Jordan (basketball), Tiger Woods (golf) and Floyd Mayweather (boxing).

Federer’s earning power reflects his career accomplishments, he holds the record for men’s Grand Slam singles titles and most weeks at world No. 1, and is second in tournament wins, with 103 titles.

On top of that, he is widely regarded as the most popular player in the game, winning ATP’s Sportsmanship Award more than a dozen times, and has been Voted the ATP Fan’s Favourite every year since he won his first major back in 2003.

The 38-year-old is also perceived as one of the most marketable athletes in sport and owns blockbuster sponsorship deals with Uniqlo, Barilla, Sunrise, Mercedes Benz, Lindt, Wilson, Jura, Rolex, Credit Suisse and Moet et Chandon to name just a few.

Federer is currently in Melbourne and will kick off his season at the Australian Open later this month, where he’ll be hoping to add another major title to his collection, along with the $2.38 million prize on offer for the winner.

The Basel-born superstar has an immaculate record at Melbourne Park, having reached the final on seven occasions, taking home the title in all but one.

Tennis fans across the globe are desperate to see this age-defying legend add to his tally of major victories, with his great nemesis Rafael Nadal just one behind him now in Grand Slam wins.
