Differs greatly depending on the fighter. They get paid a certain amount to show, often a bonus to win, possible chance for additional bonuses (ie ko/sub/fotn etc). This does not include other sponsorships etc, or taxes, fees and medical.

It goes from 4000$ (unknown newcomer) to around 300 000$ (well known, popular star)to fight. Then win bonus is usually double, except for the high purses, then its usually less. Also you have the chance for 40 000$ - 80 000$ bonus for FOTN, KO of the night or Sub of the Night.
So an unknown rookie can get 10 times salary muliplyer for a good knockout or submission.
It is also estimated that some fighters double their yearly UFC salary with sponsorship and endorsement deals. It really depends greatly on the fighter and how marketable the UFC believes they are, as well as how marketable they are to sponsors. You can google a specific ufc event, for example UFC 109 Fighter Salaries, and see what they made just based on their ring performance for the night. That number however is not necessarily all the money the UFC paid them for that fight, it could be absent specific bonuses. And obviously, it doesn't include sponsorship monies, but you can get an idea anyway.
