Floyd Mayweather Jr. claims he’ll earn $70 million for “36 minutes” of work

Floyd Mayweather Jr. eked out a tough decision win over Argentinian upstart Marcos Maidana this past weekend, getting bloodied early but surviving 12 hard-fought rounds on the back of his unparalleled technical abilities and speed in the ring to improve to 46-0 in his career.

His hard work was not for naught, however.

In a tweet, Mayweather boasted that between his base purse of $32 million guaranteed and the to-be-calculated pay-per-view revenues, he could end up earning $70 million for "36 minutes," or the amount of time a 12-round championship boxing match runs.

Financials aside, the boast is a little inaccurate in that boxers undergo grueling training for months leading up to a fight. Yet fighters at Mayweather's level rarely have a match more than twice a year, so he is making a whole lot of money for relatively little time.

And the latest financials are just one in a long string of eye-popping numbers from the highest-paid boxer in the sport's history.

While the guaranteed Maidana payout wasn't anywhere near his biggest guaranteed purse -- Mayweather set a record when he was guaranteed $41.5 million to fight Saul Alvarez last year - his 2013 deal with Showtime has given him increased control over promotion and management of his events, thus making him more money on things like TV sales and promotion. The six-fight deal Showtime floated to lure him away from HBO is estimated to be worth around $200 million, according to Forbes.

Maidana, meanwhile, was guaranteed a relatively piddling $1.5 million for the fight, but stands to make a decent cut of the pay-per-view numbers himself.

Mayweather's incredible haul from his fights have put him in elite status among the world's top-earning athletes, and given him a voice on the public stage that few modern-day boxers enjoy. At the height of the Donald Sterling scandal, he told CBS News he not only wants to buy the disgraced L.A. Clippers' owner's team, he has some changes he would make if he succeeds.

"How I would run the Clippers is, I would treat the staff fair, all the employees fair, and I would also treat the fans fair," said Mayweather.

As rich as he may be, the Clippers are expected to fetch around $600 million dollars if the league succeeds in forcing a sale. Mayweather said he's got friends who should be able to help him buy it.

"Hopefully me, Magic, Justin Bieber, and a couple other people," the boxer joked, referencing the growing list of celebrities who have indicated an interest in buying the team, a list that also includes his one-time opponent Oscar De La Hoya. "Oscar, he's a cool guy... you just never know what's going to happen."
