And it's probably even more than that.
In his 21 fights in the UFC, Michael Bisping has made at least $3,819,000 (includes 150,000 for 3 "Fight of the Nights').
I added up all the all the payouts for each Bisping fight that I could find. The ones that I couldn't find I took whatever his previous payout was and used that. His contract always went up so a lot of the cards he probably got paid more than I gave him credit for but I wanted to play it safe.
Pretty impressive career for someone who has never even gotten a title shot. After sponsorships I'd think he could have made over 5 million.
