UFC Betting Odds

The first and most important step to becoming a UFC bettor is to understand how the odds work, and how to calculate UFC betting odds.

The next major event from the Dana and the team will be UFC 300, which will take place on April 14th, 2024. The UFC 300 odds were last updated on April 3, 2024:

1st Fighter			2nd Fighter
Alex Pereira	-148	+124	Jamahal Hill
Charles Oliveira	+185	-225	Arman Tsarukyan
Zhang Weili	-360	+285	Yan Xiaonan
Justin Gaethje	-250	+205	Max Holloway
Bo Nickal	-1800	+1000	Cody Brundage

So many beginner sports bettors ignore calculations and add games to their bet slips, without doing much research or analysis into the odds and betting options. There are a few different formats of UFC betting odds, and we will briefly outline each one, even though American odds are the most popular in the United States.

American UFC Betting Odds

UFC odds are typically presented in American odds in the United States and Canada, though decimal and fractional odds are more predominant in Europe. American odds are usually represented by a positive or negative amount, like -210 or +1500 to denote the probability of winning a fight. The higher the number, the less likely that fighter will win, and the lower the negative number, the more likely that fighter is to win.

In terms of UFC betting, the positive number represents how much you would win on a $100 bet on the fight’s underdog, and the negative number would represent how much you’d have to bet to win $100 if you chose the favored fighter.

When it comes to calculating the probability of winning a fight – there really isn’t a rule for American odds, so it’s easier to convert your odds to decimal.

• For positive odds (underdog UFC odds) let’s say +300: 1 + (odds / 100) = 1+(300/100) = 4.0
• For negative odds (favored fighter’s odds) -300: 1 – (100 / 300) = 1.333

Now that you have your decimal odds, we can help you calculate your winnings and implied probability.

Decimal UFC Betting Odds

As we mentioned, decimal UFC odds are way more common in Europe – and sometimes even in the United States, some sports bettors do prefer them because they’ve been around longer.

Decimal odds are your odds multiplied by your stake, then subtract your stake.

9.0 odds would be calculated as (9.0 * $10) – $10 = $80 in winnings

1.25 would be (1.25 * $10) = $10 = $2.50

To calculate your implied probability of winning, you essentially divide 1/decimal odds which is 1/ 9.0. This will give you an implied probability of 11.11%. Implied probability is an important part of your UFC betting strategy and will help you improve your chances of winning in the long term.

Fractional Betting Odds

How did you do in math as a child? If you were a math whiz in school, you’re well on your way to understanding fractional UFC betting odds. If you see a fractionated number, like 10/1, this means someone has a ten to one chance of winning the match. This way, you can calculate their probability of winning the fight from the fractional odds.

The formula looks like this: B/(A+B) = %

For example, if the MMA betting odds are set for a match and a fighter has 9/1 odds to win, there is a 10% chance they will win the match. 1/(9+1) = .10 (10%)

Or, if a fighter has 1/ 4 odds to win the match, that can be calculated like so – 4/(4+1) = 0.80 (80%) This fighter is usually favored to win.

So, how much will you win on fractional UFC betting odds? It’s pretty simple actually. For every value on the right side of the fraction you wager, you will win the left.

So 9/1 odds – for each $1 wagered, you will win $9.

1/ 4 odds – for each $4 wagered you win $1.
