Before we delve into examples on how to calculate bet returns that have been presented in different odds formats, it is important to note that, irrespective of which odds format you use, the potential profit is the same, the presentation just differs.

Calculating profits with Decimal odds

Decimal odds are predominantly used in continental Europe, Australia and Canada. The format is a simple numerical representation of the potential return of a bet, which includes the stake amount.

The potential return on a bet quoted in Decimal odds is extremely easy to calculate by simply multiplying the amount you wish to bet by the Decimal odds offered – just remember that the return includes your stake. Here is an example of Decimal odds in a 1X2 soccer market from Pinnacle:

Calculating the potential return for a $100 Bet on Chelsea at 2.270:

Odds x Stake = 2.270 X 100 = 227

As this includes your original $100 stake amount, the potential profit is $127.

Calculating the potential return for a $100 bet on Liverpool at 3.390:

Odds x Stake = 3.390 x 100 = 339

Calculating profits with American odds

American odds are unsurprisingly the default format used in America. They start either with a positive or a negative sign, e.g. -110, or +120. A negative number indicates the amount you must stake to make $100 profit (or the equivalent in your chosen currency) and a positive number indicates how much you might profit if you bet $100 (again, this would be the equivalent in your chosen currency).

Using the example above, if you bet $124 on the Washington Redskins -2.5 handicap with American odds of -124 and they cover the spread, you will make $100 profit (plus your original $124 stake). If you bet $100 on the Dallas Cowboys +2.5 handicap with odds of +112 and they cover the spread, it will return $112 profit (plus the original $100 stake).

As with any odds format, the potential return and profit from a bet is relevant to the stake amount. Using a $100 bet example is the easiest way to calculate profits with American odds, but below is a simple formula to work out potential returns for any stake.

Negative American odds calculation:

(100/Odds) x stake

Positive American odds calculation:

Odds x (stake/100)

If we use the odds from the above example, you could bet $13.75 on the White Sox at -129 and your potential profit is $10.66:

Using the same example for positive odds, you could bet $15 on the Royals at +119 and your potential profit is $17.85:

Odds x (Stake/100) = 119 x (15/100) = 17.85

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%.
