The top 10 is heavily dominated by female athletes, including Ashleigh Barty, Naomi Osaka, Simona Halep, Caroline Wozniacki, Sloane Stephens, Bianca Andreescu and Angelique Kerber.
Following Barty’s shock retirement from tennis in March, it remains to be seen how long she will remain at the top of the rankings.
Roger Federer is the highest-earning male player of the list. His hourly rate of $199,632 (£159,795) is around four times more than the average annual salary earned by the typical American.
He is joined on the highest-earners list by Novak Djokovic and Rafael Nadal, who has made the most in winnings with an astonishing $48,898,320 (£39,125,012).
