Converting American Odds To Decimal Odds
Betting Odds Explained
When converting decimal odds to American odds there are two different formulas depending on whether you are converting odds of 2.00 or higher or odds under 2.00. Converting odds of 2.00 or higher: You take (decimal odds -1). 100. Examples: Odds of 2.2 conversion (2.2 -1).100 = +120. Odds of 3.45 conversion (3.45 -1).100 = +245. We use the closet fraction that is used in betting markets. For example, the exact mathematical equivalent of decimal odds 30 is fractional odds 29/1. However 29/1 is not used in betting markets, instead 30/1 is used, so that is what appears in this converter. Decimal odds show the amount that a bettor can win for every $1 staked. The number indicates the total return for the better, not just the profit as is seen in the other two odd formats. Here’s an example: The Stars are 1.714 in decimal odds (-140 in American). For every $1 wagered, the bettor profits 71.4 cents, plus the original stake of $1. Converting American odds to decimal odds. The easiest way to convert American odds is to use an odds converter calculator. But if you’d like the formula, here it is: For positive American odds: American odds ÷ 100 + 1. For negative American odds: 100 ÷ American odds + 1. So, using our example again: +180 odds = 180 ÷ 100 + 1 = 2.8 -220 odds = 100 ÷ 220 + 1 = 1.45.
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%.
