Tennis prize money is public down to the dollar, which makes the top of this list a useful lesson: the biggest tennis fortunes are bigger than the prize fund. These are the ten highest estimated net worth figures among the 136 tennis players with estimates on StarWorth.

Grand Slam cheques built the base, but the separation comes from everything around the sport — two decades of global endorsement deals at the very top, exhibition and appearance fees, and, for the number one name on this list, a business career in team ownership and sports management that out-earned his playing days.
Tennis also rewards longevity like few sports. The biggest names stayed commercially relevant for twenty years or more, across eras and surfaces, and converted that span into lifetime contracts with watch, clothing and racket brands that keep paying long after the last match.
