Sports betting is a popular activity that has been around for centuries. In recent years, it has become even more accessible thanks to the rise of online sportsbooks. One aspect of sports betting that can be confusing to newcomers is the use of different odds formats. We will explore what fractional odds are in sports betting, how they differ from other odds formats, and how to use them to make informed betting decisions. Whether you are a seasoned sports bettor or new to the game, understanding fractional odds can improve your betting strategy and lead to more successful wagers.
Fractional Odds in Sports Betting
Sports Betting Terms & Concepts to Know >>
What are Fractional Odds in Sports Betting?
Fractional odds are a type of odds that are commonly used in the United Kingdom and Ireland. They are expressed as fractions, such as 2/1 or 5/2, and represent the ratio of the potential payout to the original stake. For example, if you bet £10 and your bet wins at odds of 2/1, you will receive £20 in winnings, plus your original £10 stake.
Fractional odds can be used to calculate the probability of a particular outcome occurring in a sporting event. The higher the odds, the less likely the outcome is to occur, and vice versa. For example, odds of 10/1 imply that there is only a 9.1% chance of the outcome occurring, while odds of 1/10 imply a 90.9% chance.
How to Calculate Fractional Odds in Sports Betting
Fractional odds are used in sports betting to place bets on the outcome of sporting events. To calculate the potential winnings, simply multiply the stake by the odds. For example, if you bet £10 on a football match with odds of 5/2, your potential winnings would be £25 (10 x 5/2). If your bet wins, you would receive £35 in total (25 in winnings plus your original £10 stake).
Fractional odds can also be used to determine the implied probability of a particular outcome. To do this, you can convert the odds into a percentage using the following formula:
- Implied Probability = (Second Number / (First Number + Second Number)) x 100
- For example, if the odds are 2/1, the implied probability of the outcome occurring would be:
- Implied Probability = (1 / (2 + 1)) x 100 = 33.3%

Decimal Odds vs. Fractional Odds vs. American Odds
Decimal Odds
Decimal odds are commonly used in Europe, Australia, and Canada. They are expressed as a decimal point and are the easiest to understand. For example, if the odds are 2.50, it means that you will receive $2.50 for every dollar you bet. Decimal odds show your winnings plus your stake. It is a convenient format because it is easy to calculate your winnings for any bet size.
Understanding decimal odds is pretty straightforward, which is why many beginners prefer them. They are an excellent choice for those who want to keep things simple when placing bets. Decimal odds are especially helpful when dealing with multiple bets, as they allow you to quickly calculate potential returns.
Fractional Odds
Fractional odds are popular in the UK and Ireland. They are traditionally written as fractions, such as 9/2 or 5/1. The first number in the fraction represents your potential winnings, while the second number represents your stake. For example, if you bet $5 on a horse with odds of 5/1, you would win $25 ($5 x 5) plus your stake of $5 back.
Fractional odds are not as common outside of the UK, but they are still used by some bookmakers. They can be confusing for beginners because they involve fractions, but they are simple to understand once you get the hang of them.
American Odds
American odds are used primarily in the United States. They are also known as moneyline odds or Vegas odds. American odds can be positive or negative numbers and are based on a $100 bet. Negative odds indicate the favorite and show how much you need to bet to win $100, such as -150. Positive odds show the underdog and indicate how much you will win from a $100 bet, such as +200.
American odds can be a little confusing at first, but they are useful once you get used to them. They are especially popular in sports betting because they take into account point spreads, which is the number by which a favorite is predicted to win.
How to Convert Decimal & American Odds to Fractional Odds
Converting Decimal Odds to Fractional Odds
If you’re working with decimal odds, the conversion to fractional odds is straightforward. The first step is to subtract one from the decimal odds. For example, if the odds listed are 2.5, subtracting one would give a total of 1.5. This number represents the potential profit for every dollar wagered. The fractional odds can then be expressed as 3/2.
Converting American Odds to Fractional Odds
If you’re working with American odds, the conversion to fractional odds is slightly more complex. American odds are presented as a positive or negative number, with the positive number representing the underdog and the negative number representing the favorite. To convert American odds to fractional odds, the first step is to determine the implied probability of the bet. This can be done with the following formulas:
- For positive American odds: potential profit / (potential profit + initial wager)
- For negative American odds: initial wager / (potential profit + initial wager)
For example, if the American odds are listed as +150, the potential profit would be calculated as 150/100, or 1.5. The implied probability would then be 100/250, or 0.4. To convert to fractional odds, divide the implied probability by the difference between the implied probability and one. In this case, the fractional odds would be expressed as 5/2.
For negative American odds, such as -120, the potential profit would be calculated as 100/120, or 0.83. The implied probability would then be 120/220, or 0.55. To convert to fractional odds, divide the implied probability by the difference between one and the implied probability. In this case, the fractional odds would be expressed as 5/6.
Examples of Fractional Odds in Sports Betting
Fractional odds are used in a variety of sports betting markets, including football, horse racing, and basketball. They are a popular choice among bettors because they are easy to understand and offer a clear indication of the potential payout.
Example 1: Soccer – Manchester United vs. Tottenham Hotspur
Manchester United is playing against Tottenham Hotspur in the English Premier League. The odds on Manchester United to win the match are 11/10, while the odds on Tottenham Hotspur to win the match are 13/5, and the odds on a draw are 9/4.

- If you bet £10 on Tottenham Hotspur to win at odds of 13/5, and they win, you will get a return of £36.00 (including your original stake) – i.e., your winnings would be £26.
- If you bet £10 on a draw at odds of 9/4, and the match ends in a draw, you will get a return of £32.50 (including your original stake) – i.e., your winnings would be £22.50.
