As of June 20, 2018, there are only SIX Pinoy UFC fighters on this list, with only two of them actively competing in the UFC Roster.
Featherweight Rolando Dy and Flyweight Jenel Lausa are the two fighters scheduled to earn more at UFC Fight Night 132 in Singapore on June 23, 2018. Obviously, the list of earnings does not yet include their earnings for the upcoming fights.
Team Lakay's Mark Eddiva tops the list with $100, 500.00 (approximately PhP 5.3Million) career earnings as he has fought 4 times under the UFC promotion. Eddiva's stable mate Roldan Sangcha-an follows in second place with $66K (approx. PhP 3.5Million) even though he only fought twice in the UFC.
Sangcha-an received a $50K Fight of the Night bonus together with his opponent Jon Delos Reyes at UFC Fight Night 66.
Note from the source (http://thesportsdaily.com): "Athletic commissions didn’t start releasing fighter purse info until 2004, so the info below only reflects money earned from UFC 46 and onward. Also, these are only the reported salaries plus Fight of the Night, Knockout of the Night and Submission of the Night bonuses that have been made public. Many top performing fighters get additional bonuses paid out to them that aren’t reported, plus the top guys get a cut of the pay-per-view buys for events that they headline (not to mention every fighter makes sponsorship money). Official UFC Reebok sponsorship money (now known as fight week incentive pay) was added into the figures starting with UFC 189. Also, many athletic commissions don’t report fighter’s salary info, so for those we’ve estimated a fighter’s purse based on what they have earned in their other fights. Fighters with some estimated purses are marked with a * in the database. This data should still be considered very close to accurate, as most fighters’ purses remain rather predictable from fight to fight (unless they ink a new contract in the meantime)."
