1. Roger Federer, $47 millionThis is a very curious list, because it seems surprising to me that Venus would be making more in endorsements than Serena. It's also interesting, that more than half of Djokovic's $18 million comes in prize money ($11 million) while a very small fraction of Federer's comes from prize money. ($10 million of it per year comes from Nike.)
2. Rafael Nadal, $31 million
3. Maria Sharapova, $25 million
4. Novak Djokovic, $18 million
5. Andy Murray, $13.5 million
6. Andy Roddick, $13 million
7. Caroline Wozniacki, $12.5 million
8. Venus Williams, $11.5 million
9. Kim Clijsters, $11 million
10. Serena Wiliams, $10.5 million
Also, recently I blogged that Li Na had overtaken Sharapova as the world's highest paid female athlete. I understand most of the numbers used in the Forbes report are for 2010. It will be interesting to see where Li Na ends up on the list in future years, and also how much Djokovic can capitalize on his incredible, historic season.
