"According to Forbes, Novak Djokovic pocketed $20.6 million in the first 6 months of 2012, but just £9 million come from sponsorship deals.
If we exclude prize money, in 2011 Roger Federer earned $45 million, followed by Nadal (25), Sharapova (22) and Djokovic (20)."

20 mill. a year is not that bad.
