What Is an Odds Calculator?
Odds calculators quickly calculate the betting odds from one format and show you the equivalent in another format. Only with our tool, you don't convert the odds from one format to another, but you get the odds equivalent for all formats used at sportsbooks.
Our odds calculator is a key tool for understanding how the same odds are shown in different formats. It is good for working out odds you may see in promotional ads, on platforms that use alternative odds formats, or even for educational purposes.
What gives it an edge is that you also get an automatic calculation of the resulting Implied Probability of the betting odds.

Pros and Cons of A Free Odds Calculator
There are pros and cons to having such a betting odds calculator, as you can see below.
Pros and cons of using an odds calculator
- Convert between odds formats
- View implied probability
- Free and instant
- TRequires the correct input
- Does not guarantee profitable bets
What Types of Odds Are There?
Betting odds formats are generally associated with different regions and even for different betting sports, although nowadays most online sportsbooks have settings through which you can pick your favorite one. Still, it is useful to understand how each one works, as you are more than likely to encounter bets with different odds formats if you bet frequently.
Below are the most common odds formats used in sports betting:
| Odds type | Example | Brief description |
|---|---|---|
| Decimal | 1.70 | An integer with up to 2 decimal points. It shows your total payout, including your stake |
| Fractional | 7/10 | A fractional number showing your profit relative to stake. 7/10 = win 7 units for every 10 staked |
| Moneyline/American | -142 | Minimum 3-digit plus/minus sign numbers. Positive numbers = profit for every $100 wagered. Negative = stake needed to win $100. Stake not included in either calculation |
How Do You Use an Odds Calculator?
The only thing you need to do when using the odds calculator is copy the betting odds, paste it into the row for that type of betting odds, and hit calculate.
- Enter odds in the appropriate row
- Click calculate
- View converted odds
- Check implied probability
You can check how the odds appear in other formats, and at the bottom, get the resulting implied probability percentage for those odds.
A Quick Example of Using an Odds Calculator
Let's say you are looking to place a bet on an English Premier League soccer game between Manchester City and Arsenal, and you see a boosted odds offer on City to win at 6/5. The promotion is only displayed in fractional format, a format you don't use, and you want to know exactly how much that converts to in decimal format.
- Input fractional odds (6/5)
- Click calculate
- View decimal result (2.20)
- Check implied probability (~45.45%)
Now you have the odds in your preferred format, have the implied probability, and can decide whether or not you want to take that bet at that price.
Who Can Benefit from Using an Odds Calculator?
Odds calculators are useful for all bettors, it all depends on how you use it.
New Bettors
- Understand Odds Formats
- Avoid Mistakes
Experienced Bettors

- Compare Value
Budget-Focused Bettors
