The basics: The MMA odds calculator in a nutshell
UFC betting is bigger than ever before, and pretty much all leading bookmakers now offer odds on the UFC and other MMA fights. However, you will find that the odds of these fights will vary considerably between sportsbooks. Finding the site with the best odds can make a considerable difference to your bottom line. For example, a $10 bet to odds of 4.00 will give you a return of $40 if successful. But if you place the same bet at a site offering odds of 6.00, your potential returns will be $60.
To muddy the waters somewhat, different betting sites post their odds in different formats. So whilst one site may show odds in decimal format, another site may display fractional odds and a third site shows the price in the American odds format.
Sounds confusing? That’s where an MMA betting calculator comes into its own. All you have to do is input the odds in the format used at each sportsbook, hit the ‘Calculate’ button and the tool will convert the price into all possible formats. Better yet, it will also tell you the implied probability of your bet. In other words, the percentage chance of it being successful. Here’s an example of how different formats display the same odds:
| Odds format | Odds displayed |
| American | +300 |
| Fractional | 3/1 |
| Decimal | 4.00 |
| Hong Kong | 3 |
| Indonesian | 3 |
| Malay | -0.333 |
| Implied probability | 25% |

How an MMA odds calculator can enhance your betting life
The number one reason why you need to use an odds calculator is that it allows you to compare odds and find the best price for your bet, regardless of the format displayed by your chosen sportsbooks. This will save you a substantial amount of time and effort, as it cuts through the confusion and gives you all your options in the same odds format.
It is also important to note that an odds calculator can be used for a whole host of different MMA bet types (more on that below). So regardless of whether you are placing a moneyline bet, a parlay, a spread or even an MMA prop bet, you can use the calculator to view the odds in any format.
The only minor potential drawback to using a
moneyline calculator
is that if you are betting in-play on a UFC fight, the odds can change extremely quickly. This makes comparing odds a very tricky process. However, it is worth bearing in mind that live betting is a very fast paced activity, regardless of whether you are using an odds calculator or not.
Pros and Cons of using an MMA betting odds calculator
Now that you know how an MMA odds calculator works, let’s look at the practical benefits (plus one potential drawback) of using an odds calculator when betting on MMA.
Pros & Cons of UFC Betting Odds Calculator

- Save time
- See all your options in the same odds format
- Difficult to use when live betting on fights
Four top tips for using an MMA odds calculator
Hopefully, you now have an excellent understanding of how to use an odds calculator and you can see why they are so important to your UFC betting experience. To help you get the most out of our calculator, I have put together some essential tips:
🏆 Use the Calculator Effectively
You can input the odds for any MMA bet type into our calculator, BUT I can highly recommend sticking to easy to understand wagers when you first begin using the tool. In other words, just look at some simple moneyline markets and use the calculator to compare the odds on each fighter at various sites. Once you are completely comfortable using the tool, you can move on to parlays and other types of wagers.
We have made our odds calculator as simple as possible to use, but you should still take a few seconds to double check your entries each time, before hitting the calculate button. One incorrect digit can result in a misleading calculation and a poor betting choice. This is especially important when making parlay bets - always make sure you have added the correct selections to your bet slip at each betting site, before you use the calculator.
📊 Find the Best Format for You
All odds formats have their advantages and disadvantages, making it impossible to say with any degree of certainty which one is the best. Therefore, you need to look at all of the formats and decide which one works best for you. Which do you find the easiest to understand? Which format gives you the clearest picture of the overall market situation and enables you to immediately spot the best value? Once you have established the answer, concentrate on that format whenever you use our tool.
Betting odds can change at any time, so to ensure that you get the most accurate picture of the latest MMA markets, use our tool immediately after checking the current prices. Whilst there is no guarantee that those prices will remain stable, taking swift action minimises the likelihood of the odds altering.
Other calculators you can use for MMA betting

Whilst MMA events typically carry fewer betting markets than many other sports, there are still plenty of options available to fans of the sport. The good news is that we have
betting calculators
for all of those bet types. Here are three of the most popular:
- Parlay calculator
- Most sports fans have heard of an
NBA parlay calculator, but if you want to bet on multiple UFC contests, a calculator can still be extremely useful. All you have to do is input your stake, plus the odds for each selection on your parlay. The calculator will then tell you the combined odds of the bet, plus your potential returns.
- Hedge calculator
- Hedging involves placing an initial bet on one fighter, and then going to a second betting site to place a bet on his opponent. By using a
hedge calculator
you can ensure a win regardless of the outcome.
- Spread calculator
- A UFC spread bet will usually involve predicting how long a fight will last. Understanding spread markets can be tricky, so using our spread calculator can save you a lot of time and hassle.
Conclusion - An MMA odds calculator can be your new best friend
If you ever bet on the UFC or any other form of MMA, then our odds calculator could take your game to a whole new level. At first, you may think that it is adding an unnecessary extra task to proceedings, but trust me, before long you will be wondering how you ever got by without it. And because our MMA odds calculator is designed with the user in mind, it is incredibly simple to use. In no time at all, it will be your ‘go to’ tool when weighing up betting prices across multiple sites.
