Since Mayweather get a cut of pay-per-view sales, gate, foreign television sales, sponsorships, merchandise and closed circuit sales he is going to make far more than his $32 Million Guarantee. Once it is all said and done depending on how well the PPV does Mayweather will take home between $50-75 million of the fight.
Maidana is guaranteed a minimum of $3 million, but that will also increase depending on the PPV buys and some of the overseas PPV. He will probably pull in between $5-10 million in total for the fight.
