The figures do not represent a full accounting of each fighter’s income.
Fighters bear significant costs typically including training expenses, a percentage to management, a percentage to the trainer, plus insurance, licenses, and taxes.
On the income side, sponsorship money can be a substantial portion of income, although they have markedly dropped lately. As well there are explicit ‘of the Night’ performance bonuses, and less formal ‘locker room bonuses.’
Headlining fighters typically also receive a stepped percentage of PPV buys, that increase if the fighters drawing power pushes the number higher.
And many fighters earn income from teaching, from appearances, and in some cases from regular employment in the non fighting space.
