As you begin your journey into sports betting, it is essential to understand the different formats of odds. Understanding how odds are expressed can make all the difference when it comes to making informed decisions and making a profit. In this article, we will explore the three most common formats of odds: decimal, fractional and American.

Decimal Odds

Decimal probabilities are widely used, especially in Europe and Australia. In this format, the odds are expressed in decimal numbers, representing the total amount you will receive if your bet is a winner, including the amount wagered.

For example, if the decimal odd is 2.50 and you bet £100, your total return is £250 (£100 bet + £150 profit). To calculate profit in decimal odds, simply multiply the odd by the amount bet and subtract the amount bet from the result.

Fractional Odds

Fractional odds are common in the UK and Ireland. In this format, the odds are expressed as fractions, where the numerator represents the amount you will win and the denominator indicates the amount bet.

For example, if the fractional odd is 3/1 and you bet £50, your total return is £150 (£50 bet + £100 profit). The profit in fractional odds is calculated by multiplying the amount wagered by the numerator of the fraction and dividing by the denominator.

American Odds

American odds are widely used in the United States and other markets. In this format, there are two types of odds: positive and negative.

Positive odds indicate the profit you will make for each $100 bet. For example, if the odd is +200 and you bet $100, your profit will be $200.

Negative odds, on the other hand, indicate the amount you need to bet in order to make a £100 profit. For example, if the odd is -150, you will need to bet £150 to make a £100 profit.
