ODDS FORMATS used in online bookmakers
There are different formats of the betting odds in the different part of the world. Most of the online bookmakers offer automatic recalculation so you do not need to do it yourself but it is important to recognize and understand the correctly if you plan to place bets on different sportsbooks. The place to switch the odds in your preferred format normally is the on the top right corner.
1 European (decimal) odds: they are the most popular format in Europe, Canada, Australia and New Zealand. They are decimal numbers showing the possible gross return of a bet. For example: the coefficient 1.50 means that if you bet $100 and win you will receive $150 ($100 the initial stake and $50 profit). If the coefficient is 2.50 and you bet and win you will receive $250 ($100 the initial stake and $150 profit).
2 British (fractional) odds: are popular in the United Kingdom. They are fractions and the profit is calculated by multiplying the stake by the odds. For example we bet $100 at odds 3/5. If the bet is winning our profit is $100 x 3 / 5 = $60. If the odd is 8/5 and the bet is successful the profit is: $100 x 8 / 5 = $160. The main difference between European and British odds is that the decimal odds give you the gross return (the initial stake + the profit) whereas the fractional odds give you the profit.
3. American odds are used mainly in USA. They are divided into two groups positive and negative. The negative coefficients indicate that the profit of a bet is below 100% of the stake and the positive that it is above.
The positive odds are showing how much money can be profited on a $100 bet. For example +400 means that if you bet $100 and win the profit will be $400.
The negative odds indicate how much money have to be wagered in order to make a profit of $100. For example -200 means that you need to stake $200 to make $100 profit.
4. Indo odds are popular in Asia (especially in Indonesia). They are similar to the American odds being positive when the profit is more than 100% of the stake and negative when it is below. The difference is that they are on $1 stake whereas the American odds are based on $100 stake.
5. Hond Hong (HK) odds are popular in Asia. They are very similar to the European odds. The difference is that they do not show the total return of a stake but only the profit. For example the Euro coefficient 2.50 means that if you bet $100 and win will get profit of $150. The HK odd 2.50 means that if you bet and win you will get $250 profit.
6. Malay odds are popular in Malaysia. They are very similar to the American odds and Indo odds in having positive and negative groups. The difference is that the positive groups are for odds with less than 100% profit on the initial stake.
