The figures do not represent an accurate assessment of each fighter's income.
Fighters bear significant costs including training expenses, a percentage to management, a percentage to the trainer, insurance, licenses, and taxes.
On the income side, sponsorship money can be substantial, although they have dropped markedly over the past couple of years. Further, the UFC often gives out undisclosed "locker room" bonuses for exceptional performance. In addition there are publicly announced 'of the Night' bonuses noted at top.
Lastly, many fighters earn income from teaching, from appearances, and in many cases from regular employment in the non fighting space.
