The above figures are the fighter payout information that promoters are required by Massachusetts regulations to submit to the state athletic commission; they do not represent a full accounting of each fighter’s income.

Fighters bear significant costs including training expenses, a percentage to management, a percentage to the trainer, plus insurance, licenses, and taxes.

On the income side, fighters earned sponsorship of between $2,500 and $40,000 for wearing Reebok apparel in the Octagon, and for the week before it. Some fighters receive discretionary “Locker Room” bonuses in the mail. Although it is not usual, in some cases there is an LOA [Letter of Agreement] on the contract for additional income. Four $50,000 ‘of the Night’ Performance Bonuses, are awarded. Further, main event PPV fighters receive a percentage of the PPV gross, as contracted, generally at a rate that escalates with increased PPV buys. Out-of-event sponsorship money too can be a significant, although it is much, much smaller for many fighters than it was in the past. And lastly, many fighters earn income from teaching, from appearances, and in many cases from regular employment in the non-fighting space.
