If you are new to betting, learning how to understand, and find value in betting odds is a fundamental skill. In this guide, we will explain the three most common betting odds formats, and teach you how to work out the implied probability the betting odds represent. Gambling sites use three different formats for betting odds, Decimal, Fractional, and American.
Decimal betting odds are the default format for most online betting sites in India, and they are also our recommended format. The decimal odds represent the potential returns of the bet including the stake. Multiply the decimal odds by the amount you wish to bet to work out your potential return, and minus your stake to calculate the profit.
(Decimal odds x stake = returns - stake = profit)
Example: 2.50 x 100 = 350 - 100 = 250 profit
Fractional betting odds are common in English speaking countries, with the United Kingdom using fractional odds as the default setting for most gambling sites. There is a simple way of understanding fractional betting odds.
Example: 3/1 = How much you win/how much you stake
For every 100 rupees you stake, you will win 300 rupees, simple as that.
1/5 = Every 500 rupees you stake, you will win 100 rupees.
American, or Moneyline odds, are shown as positive (+) or negative (-) numbers. The positive numbers show how much you might profit if you bet 100, and the negative number shows what you must stake to win 100. We do not recommend using the American style betting odds, but if you find it easier, most online betting sites offer the Moneyline odds format as an option.
Odds reflect the implied probability of an event occurring, and it is important to know how to change the odds into a percentage to work out if there is value in the bet. We recommend using decimal odds, as you just need to divide 100 by the decimal odds to work out the percentage.
Example: 100/2.50 = 40%
Let's say, two football teams have seen both teams score in a combined average of 70% of their games.
If both teams to score was set at 2.50 (40%), there would be value in the odds offered compared to the 70% average.
