Steffi Graf — Net Worth and Career Earnings
Steffi Graf has an estimated net worth of $400 million as of 2026, one of the wealthiest retired female athletes in history. The Brühl-born German won 22 Grand Slam singles titles — more than any other player in the Open Era when she retired in 1999, a record that Serena Williams subsequently surpassed. Her 377 weeks as world number one remain an all-time record for any player, male or female. In 1988 she became the only person in the history of tennis to achieve the Golden Slam — winning all four Grand Slam tournaments and the Olympic gold medal in a single calendar year, a feat that most tennis authorities consider effectively unrepeatable given the condensed scheduling required.
Her endorsement income during her playing peak reached approximately $30 million annually from partnerships with Adidas, Opel and Barilla. She married Andre Agassi in 2001 — their combined net worth of over $500 million makes them the wealthiest couple in tennis history. Their joint philanthropic work through the Andre Agassi Foundation and Graf's Children for Tomorrow charity has generated hundreds of millions in charitable giving. She was inducted into the International Tennis Hall of Fame in 2004. At 56, her post-career investments and Agassi's business ventures have maintained and grown their combined fortune.
