Hong Kong Odds (also known as HK Odds)

Hong Kong Odds are mainly used by people living in Hong Kong. Until 1997, Hong Kong was under British rule and therefore it should not be a surprise that HK odds closely resemble traditional British odds. The only difference is that HK odds are written in a decimal notation whilst the UK odds use fractions.

Hong Kong odds, as well as their UK counterparts, both quote the net return that will be paid out to the bettor should he win, relative to his stake. Odds of 1.2 in Hong Kong are the same as 6/5 (“six-to-five”) in the UK and both imply that the bettor will earn a net profit of £120 from a £100 stake. Should the punter win, he always receives his original stake back, plus the profit.

It follows that if the HK odds are 1.2 and the stake is £100 then the total return is £220 (£120 winnings plus the original £100 stake).

Decimal Odds (also known as European or Continental)

Decimal odds are standard on betting exchanges and they are favoured in continental Europe, Australia, and Canada.

Decimal odds are equivalent to the decimal value of the fractional odds, plus one. Because decimal odds are simply 1 divided by probability (= 1/probability) they are easier to use in calculations and we therefore favour them for our articles and explanations.

Thus, ‘even odds’ 1/1 are quoted in decimal notation as 2.0; the 6/5 fractional odds (1.2 HK odds) discussed above are quoted as 2.2. Decimal odds quote the net return paid out to the bettor PLUS the original stake.

So if the odds are 2.2 and the stake is €100 then the total return is €220 (€120 winnings including the original €100 stake).

TWO-TIERED – MONEYLINE ODDS

Odds commonly referred to as ‘moneyline’ are the odds which are mainly used by US bookmakers. These odds mean the money wagered either to win 100 units, or the money which will be won from a 100 unit wager.

Please note that both Indonesian and Malaysian odds are also ‘moneyline’ odds although often wrongly referred to just as ‘decimal odds’, probably due to their decimal notation, whilst US moneyline odds are shown in whole numbers.

However, both Indonesian as well as Malaysian odds have the same underlying formulas as the US moneyline odds, only that their basis is 1 unit and not 100.

Moneyline (also known as American Odds, or US Moneyline)

Moneyline odds are favoured by American bookmakers.

The figure quoted can be positive or negative, and depends on the probability to win the bet.

Positive Figures: UNDER 50% probability of winning the bet

A positive moneyline quotes the money won from a 100 unit stake. In other words, a positive moneyline shows the potential win from a 100 unit wager. Talking of formulas, if the probability of winning the bet is less than 50%, then the net return is multiplied by 100.

The 6/5 fractional odds (1.2 HK odds, 2.2 decimal odds) discussed above translate into +120 moneyline. This means the net return paid out to the bettor for a 100 unit stake.

So if the odds are +120 and the stake is $100 then the total return is $220 ($120 winnings plus the original $100 stake).

Negative Figures: OVER 50% probability of winning the bet

A negative moneyline shows the stake amount needed to win 100 units. In other words, a negative moneyline shows the potential loss. Again, from the formula perspective, if the probability of winning the bet is higher than 50%, then minus 100 is divided by the net return.

Fractional odds of 1/4 (0.25 HK odds, 1.25 decimal odds) translate into -400 moneyline. These odds stand for an implied probability of 80% to win the bet, and a net return of 25%. The bettor needs to wager (stake) 400 units in order to win 100.

So if the odds are -400 and the intended profit is $100 then the stake needed is $400 for a total return of $500 ($100 winnings plus the original $400 stake).

Probability exactly 50%

If the probability to win is exactly 50%, then moneyline odds are either quoted as +100 or -100. Some bookmakers display the negative symbol while others do not. There is no rule.

    Betting odds are expressed in three popular formats: fractional (British), decimal (European) and American (moneyline). These formats hold no difference in terms of final payoffs. Fractional odds are the ratio of the amount (profit) won to the stake; Decimal odds represent the amount one wins for every $1 wagered; and American odds, depending on the negative or positive sign, either indicate the amount one needs to wager to win $100 or the amount one would win for every $100 staked.

    So, if you are planning to enter the betting or the gambling world, it is important to understand and interpret these types of odds well.
