Positive odds - 100 divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g. American odds of 150 = (100 / (150 + 100)). 100 = 40%. Negative odds - Firstly multiply the american odds by -1 and use the positive value in the following formula: american odds divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g. American odds of -300 = (300/(300+100)). After knowing the implied probability, the next step is to know which odds are in favor of the wager. To convert the probability into decimal odds, 1 is divided by the probability and the resulting value is the outcome. Formula: 1/probability = Outcome. Example: Outcome = 1/ (64.4/100) = (1/0.644) = 1.55. Getting Fractional odds from Implied Probability.

The mathematical concept of odds is related to, yet distinct from the concept of probabilities. In simple terms, odds are a way of expressing the relationship between the number of favorable outcomes in a given situation versus the number of unfavorable outcomes.

Betting Odds Explained

American Odds – American Odds are the default odds format at most US friendly betting sites as well as Nevada sports books. Here odds are expressed as either a negative or a positive number. When positive the odds represent how much a player will profit on a successful $100.00 wager. So for example if the odds are +180 a successful $100 bet will return $280 (the $100 stake + $180.00 win). When the odds are negative they represent how much a bettor must stake to win $100. Therefore $150 staked at -150 returns $250.00 (the $150 stake + $100 win).

Decimal Odds – Decimal Odds, also referred to as European Odds, are used in most European countries and are the default option of many Asian bookies as well. This is the easiest odds format to understand as the odds represent how much a 1 unit wager returns. For example a €1 wager at odds 1.91 returns €1.91. This return includes both your stake plus profit; to calculate how much your return will be simply multiple your stake by the given odds.

Fractional Odds – Fractional Odds are used in the UK and Ireland. Here the first number is the amount to be won, and the second number is the stake. So for examples 4/1 is stake 1 to win 4, and 10/11 is stake 11 to win 10. To calculate how much a winning bet will profit, convert the fraction to a decimal and multiply it by the stake. For example 3/2=1.5, so, if wagering at 3/2 a successful bet will return 1.5 times your stake in winnings and will also return your stake.

Implied Probability – Implied Probability is how often a bet must win to average break even. This is calculated as risk/return, so for example +200 in American format (3.00 European) is risk $100 to win $200 so a winning wager returns $300 ($100 stake + $200 win). Therefore the implied probability of +200 is $100/$300= 0.3333, which is 33.33%. For this reason you should only wager at +200 if you think the probability of winning is greater than 33.33%.
