Roger Federer has become the world’s richest tennis player, with career prize money earnings listed as a staggering $US43.29 million ($A66.56 million).
Federer’s passage into the third round of the ATP Madrid Masters event yesterday saw the Swiss player edge past former No.1 Pete Sampras of the United States.
Federer will take his earnings to $US43.5 million ($A66.88 million) should he win in Spain. Sampras earned $US43.27 million ($A66.53 million) in his career.

Current world No.1 Rafael Nadal stands eighth in the list with $US20.5 million ($A31.52 million) in earnings, while legends Bjorn Borg, John McEnroe and Jimmy Connors do not even make it into the top 10.
