Not too many prizefighters have lived up to their nickname quite like Floyd "Money" Mayweather.

The pugilist formerly billed as “Pretty Boy” made a handsome living throughout his Hall of Fame career, totaling an inflation-adjusted earning of $1.2 billion, good for sixth place on the all-time athlete earning list released by Sportico.

The Penske-owned upstart sports business media company indicated Mayweather made a non-inflation adjusted total of $1.08 billion. 

Basketball icon Michael Jordan topped the inflation-adjusted earning list at $2.62 billion. The top five was rounded out by golfers Tiger Woods ($2.1 billion), Arnold Palmer ($1.5 billion), Jack Nicklaus ($1.38 billion) and soccer star Cristiano Ronaldo ($1.24 billion).

Four other boxers made the top 25 list, including Mike Tyson at No. 16 with $775 million, Manny Pacquiao at No. 18 with $630 million and Oscar De La Hoya at No. 23 with $580 million.

The non-inflation adjusted figures featured the following for each fighter: Tyson ($445 million), Pacquiao ($550 million), De La Hoya ($405 million).

Sportico outlined its methodology with the following criteria:

“Sportico’s earnings estimates are based on conversations with industry insiders, Sportico research and historical estimates in media outlets, such as Forbes. Earnings include salaries, prize money, purses, bonuses, endorsements, licensing, royalties, memorabilia, book deals, appearances and golf course design. We included cash earned from equity stakes in sponsor companies … but did not factor in traditional investment income. Sportico included earnings during playing careers and retirement through June 1, 2021, and adjusted them for inflation. Earnings are calculated up until the time of death for Palmer and Kobe Bryant.”
