Types Of Betting Odds Formats

American Odds

Also known as moneyline odds, they are given the name American odds because they are the most prolific form of odds you will find when you wager with a sportsbook that caters to North American bettors.

Here's how American odds work - let's say the Toronto Maple Leafs are listed as -150 playing the Minnesota Wild at +210:

  • The team with the minus odds, in this case the Leafs, are the favorites, and
  • The team with the plus odds, the Wild, are the underdogs.

Here's how you would calculate the value of a bet on this game. A positive moneyline indicates the return you would get on a winning $100 wager. So if you bet the Wild and they won, you would turn a $210 profit on your $100 wager. A negative moneyline shows how much you will be required to wager on the game in order to turn a profit of $100. To win $100 on the Leafs, you'd need to bet $150 that Toronto would prove victorious.

Converting from American to Decimal odds:

  • For positive US odds: Decimal odds = (US odds/100) +1
  • For negative US odds: Decimal odds = (100/US odds) + 1

Fractional Odds

If you've ever been to the racetrack to play the ponies, then you are familiar with fractional odds. Also often referred to as British odds, payouts are easily calculated by multiplying the stake you play with the odds being offered. For example, if the odds were 3/1 and you bet $100, you'd multiply 100 x 3 to determine your winnings. So your profit on this bet would be $300.

Things get a bit more complicated when the bottom number on the odds is not one. Say the favorite in a horse race is listed at 5/2. In this case, you divide the top number by the bottom number and then use that outcome to multiply your stake. If you wager $100 on this horse, you would start by dividing 5 by 2. That leaves you 2.5, which you would then multiply by your $100 stake, providing you a profit margin of $250.

Decimal Odds

Also called European odds, this odds format, as you might expect from that name, is popular and commonplace in Europe. But it's also the easiest odds format in which to calculate a payout. There's no fractions or negative payouts involved here. It's all very straightforward. Let's say it's time for the Real Madrid-Barcelona derby in Spain's La Liga. You're a Lionel Messi fan, so you plan to bet $100 on Barcelona to win at odds of 2.50. 

Here's how simple it is to figure out what you are in line to win if Messi comes through and Barcelona downs their arch rivals. You just take your $100 wager and multiply it by 2.50. That's it. We told you it was easy. And when you do the math, you will find that your profit margin on this game would be $250.

Converting from Decimal to American odds:

  • To convert a Decimal odd of 2.00 or greater: US odds = (Decimal – 1) x 100<
  • To convert a Decimal odd of less than 2.00: US odds = (-100)/(Decimal -1)

International Sports Betting Odds

In other parts of the world, you will come across some lesser-known forms of odds. Here's a breakdown of some of them:

Hong Kong Style Odds

Hong Kong odds are merely another type of decimal wagering. You might see a soccer game between Germany and Switzerland and the odds on Germany are .6. To calculate your payout on a $100 wager, it would be the stake ($100) x (1 + the odds). In this case, that would be $100 x 1.6. You would be left with $160 in winnings, of which $60 would be profit on your bet.

Malaysian Odds

A popular place where people go to bet on soccer, Malaysian odds are similar to American odds, with one significant twist - the underdog gets the minus odds and the favorite is assigned the plus odds. And instead of measuring their odds in units of 100, Malaysian odds utilize units of one. Malaysian odds of 1.00 would represent a 50/50 wager on a game. Odds of 0.50 would return 50 percent of the original stake, while odds of -0.50 would earn you a 150 percent payout on your original wager.

Indonesian Odds

Not unlike Malaysian odds, Indonesian odds employ a base unit of one. But unlike Malaysian odds, Indonesians odds follow the American odds format where favorites are indicated by a minus sign and underdogs with a plus sign. So Indo odds of 1.50 would return $150 on a $100 wager and odds of -1.50 would require a $150 wager to garner a $100 profit. By utilizing this unique format, it enables Indonesia to signify which sportsbooks cater specifically to their market.
