Odds Formats
Betting Odds Types
Odds for various outcomes of a sports event in a single (ordinary) bet can be presented by a bookmaker in different formats:
- European (decimal)
- English (fractional)
- American
- Hong Kong, and others.
The European format , also known as decimal , is typically used in continental Europe, Canada, and Australia. In the decimal format, the odds represent the ratio of the total payout to the bet amount. To determine your potential winnings, you simply multiply your bet amount by the decimal odds. If the odds are 2.00, it means an even chance bet, and if one side wins, the net winnings will be the same as the other side would have received if the match or game had gone in their favor.
The English format of odds ( fractional ) is commonly used by bookmakers in the United Kingdom. It is calculated as the ratio of net winnings to the bet amount. Odds of 1/1 correspond to an even chance bet.
The American format is predominantly used in the United States. In this system, the odds represent the net profit you can make when betting 100 units with positive odds, and the amount you need to bet to win 100 units with negative odds. If the odds are 100, it's an even chance bet.
Bookmakers in the Asian market most often use formats like Hong Kong, Malaysian, and Indonesian odds. These odds are designed to predict the hypothetical outcome of a sports event with an assumed probability of the outcome, allowing for risk-free betting.
| Decimal | Fractional | American | Hong Kong | Indonesian | Malaysian |
