In addition to being paid a fixed amount to show and another, usually equal amount to win, each UFC event also awards four $50,000 Performance Bonuses. Usually, there is a Fight of the Night in which both fighters are given a performance bonus, and a performance bonus to the winner in two fights. “Performance Bonus” means the fight made you say “HOLY F@#$ING $#!@.”

One of the primary differences between the UFC model and the boxing model is the depth of the card. Sometimes the greatest fight isn’t the main event. At UFC 219 the main and the co-main each won bonuses, but the fourth performance bonus deservedly went to the only prelim fight on UFC Fight Pass.

Fight of the Night of the Night: $50,000 bonuses
•Cris Cyborg defeated Holly Holm by Unanimous Decision (49-46, 48-47, 48-47)

In addition, to the bonuses and purses, there is:
•Reebok pay, based on tenure, for wearing the distinctive apparel during fight week and in the Octagon;
•Sometimes fighters get discretionary locker room bonuses of varying amounts; despite their name, locker room bonuses actually come in the mail now;
•In some cases there is an LOA [Letter of Agreement] on the contract for additional income; and,
•The most elite fighters get points on the pay per view, although that has no relevance to FOX event.

The next league event is UFC Fight Night 124: Stephens vs. Choi on January 14, 2018 at Scottrade Center in St. Louis, Missouri, United States.
