2.50 3/2 +150
5.00 4/1 +400

Remember: All three odds formats represent the same probability and payout – just expressed differently based on regional preferences.

What are Decimal Odds?

Decimal odds are commonly used in Europe and other parts of the world. They are represented as decimal numbers, such as 2.50 or 1.80. To calculate the potential payout, you multiply the decimal odds by the bet amount.

For instance, if you bet €20 at odds of 2.50, your potential payout would be €50, including your original €20 stake.

Why are betting odds important?

Betting odds are crucial because they provide valuable insights into the potential outcome of a bet and the associated risks. They help you assess the likelihood of an event occurring and enable you to make more informed betting decisions.

By understanding the odds, you can evaluate the potential payout and profit, weigh the risks, and determine if a bet is worth pursuing.

The betting odds calculator simplifies this process, saving you time and effort while ensuring accurate calculations.

What are Fractional Odds?

Fractional odds are often used in the United Kingdom and Ireland. They are displayed as fractions, such as 2/1 or 5/2, where the first number represents the potential profit, and the second number represents the amount wagered.

For example, if you bet £10 at odds of 3/1, your potential profit would be £30, and the total payout would be £40 (including your original £10 stake).

What are American Odds?

American odds are prevalent in the United States. They are displayed with a plus (+) or minus (-) sign, followed by a number, such as +150 or -200. Positive (+) odds indicate potential profit on a $100 wager, while negative (-) odds represent the amount you need to bet to win $100.

For example, if you bet $100 on a team with odds of +150, your potential profit would be $150, and the total payout would be $250 (including your original $100 stake).
