When it comes to sports betting, there are three main types of odds formats used around the world: American, European, and British.
While they may appear different, they all represent the same underlying probability and potential payout. Understanding these odds formats is crucial for bettors to accurately assess the value of their bets.

American Odds
American odds, also known as moneyline odds, are the most commonly used format in the United States. They are based on a $100 unit and can be either positive or negative:
- Positive odds (+) indicate the amount of profit you would make on a $100 bet. For example, +150 means a $100 bet would pay out $150 in profit, for a total return of $250.
- Negative odds (-) indicate the amount you need to bet to win $100. For instance, -200 means you would need to bet $200 to win $100, for a total return of $300.
European Odds
European odds, also known as decimal odds, are commonly used in Europe and other parts of the world. They represent the total amount paid out for every $1 bet, including the original stake. For example, odds of 2.50 mean a $1 bet would pay out $2.50 in total, with $1.50 in profit.To calculate the potential profit using European odds, simply subtract 1 from the decimal value. For example, with odds of 2.50, the profit on a $10 bet would be: $10 x (2.50 - 1) = $10 x 1.50 = $15
British Odds
British odds, also known as fractional odds, are commonly used in the United Kingdom. They represent the ratio of the profit to the stake. For example, odds of 3/1 mean for every $1 staked, the potential profit is $3. If you bet $10 at 3/1 odds and win, you would receive $40 back ($10 stake + $30 profit).To calculate the potential profit using British odds, simply multiply your stake by the numerator and divide by the denominator. For example, with odds of 3/1, the profit on a $10 bet would be: $10 x (3/1) = $30
Converting Between Odds Formats
While the different odds formats may appear confusing at first, they can be easily converted between each other. Here are the formulas for converting between the three types:
- American to European: Divide the absolute value of the American odds by 100, then add 1 if the odds are positive, or subtract 1 if the odds are negative.
- European to American: Subtract 1 from the European odds, then multiply by 100. The result will be positive if the original European odds were greater than 2.0, or negative if they were less than 2.0.
- American to British: Divide the absolute value of the American odds by 100, then express as a fraction with the denominator being 1. The result will be positive if the original American odds were positive, or negative if they were negative.
Understanding the different odds formats and being able to convert between them is essential for bettors to accurately assess the value of their bets and make informed decisions when placing wagers.
