It costs tournament organisers more than $1 million just to get a starting guarantee from Federer's management. Meanwhile, Forbes reports, that his 10-year contract with Nike is worth a total of $100 million. More than 14 million people are fans of his Facebook account.
"Consistency for so many years has benefitted Federer's brand value greatly. In his case, it doesn't even matter if he wins another big tournament again," Hans-Willy Brockes, the head of Europäische Sponsoring Börse (ESB), told Credit Suisse.
"A brand's value generally comes from its recognition and the ability to generate sales and earnings based on this recognition. That's why Google and Apple are among the most valuable brands ever, while the brand value of Basler Läckerli cookies is much lower."
