What is a dominance score?

A dominance score rates how one-sided a UFC fight was, out of 100. The winner takes their share and the loser keeps the rest, so a 90–10 fight was far more one-sided than a 70–30 one. It is the per-fight measure behind the Dominance Index rankings. The highest score of 2026 so far is 99–1: Cody Haddon over Aoriqileng, KO/TKO, 30 May 2026.

How is it calculated?

It starts from how the fight ended: 85 for a knockout or submission, 80 for a doctor stoppage, 76 for a unanimous decision, 73 for a majority and 70 for a split. Up to 15 more is added for how one-sided it was: significant strike difference carries 40% of that, control time 30%, knockdowns 20% and how early a finish came 10%. Each signal stops counting at the level of the most one-sided tenth of UFC fights: 43 more significant strikes, seven more minutes of control, one more knockdown.

What counts as a dominant win?

A win scoring 85 or more. That is any finish, or a decision won by a wide margin. Fighter pages and the rankings count each fighter's dominant wins, for example 5 of 6.

Can a dominance score compare fighters in different weight classes?

Yes. The score describes a single fight, so it compares across weights, which is why the most dominant lists cover every division together. Ratings do not: each division is rated on its own scale.

Which fights have no score?

Fights without round-by-round statistics, mostly from the early years, count as a plain win or loss and show a dash. Draws split 50 to 50. No contests are not scored.

How does the score feed the rankings?

Before every fight the two fighters' ratings set an expected score. The rating moves by how far the real score beat or fell short of it, so a dominant win over a highly rated opponent moves a rating furthest. The full method is on the How it works page.
