Indonesian Odds

Indonesian odds, also known as Indo odds, are similar to American odds. They both use plus (+) and minus (-) signs to indicate whether a selection is the favourite or underdog, while no sign implies positive odds. The key difference is that American odds are divided by 100 to get Indonesian odds. Therefore, American odds of +115 are expressed as 1.15 in Indo odds. Easy, right?

Indonesian Betting Odds

Indonesian odds are very similar to American odds, they are the same odds divided by 100.

The positive numbers, such as +115, are simply expressed as 1.15, and the plus sign is always implied if it is not there. Negative odds in the Indonesian format simply show how much money you must risk in order to win one unit. Usually these odds are displayed to two decimal places, sometimes more for certain bets.

Using Indonesian-style odds, an even money bet would be quoted as 1.00.

Here are some examples to better illustrate how Indonesian odds work:

Example 1: Brazil to beat Japan

Brazil are listed at Indonesian odds of -1.15. This means that for each unit won, you would need to risk 1.15 units.

This means you’re risking $115 to secure $100 in profit (risking 1.15 units to win 1 unit).

A successful $115 bet returns $215.

Example 2: Japan to beat China

China is listed as the underdog at Indonesian odds of 2.10.

This means that for each unit bet, you would win 2.10 units.

A successful $100 bet returns $210, so you’re risking $100 to win $110 (risking 1 unit to win 1.1 units).

The big difference between ‘+’ and ‘–’ Indonesian odds is that in the first example you are risking more than one unit to win one unit. In the second example, you are risking one unit to win more than one unit. For even money bets, you risk $1 to win win $1.

Sports Betting in Indonesia

Indonesian sports betting is a sore subject in that country. Sports betting is technically illegal, making it very hard for fans to bet on their favorite teams and games. Of course, this ban on sports betting has simply driven most action into the shady underworld along with other activities the authorities deem questionable. The police are constantly struggling with average folks simply looking to get some action down on the games.

With the internet, it is easy for unregulated books to open up shop and offer lines to Indonesians. This has led to police watching Wi-Fi hot spots such as bars and restaurants where customers have laptops on and are watching sports. It is rumored that bookies simply use the web as a conduit and direct bettors to certain sites to place bets, and then make transfers via bank accounts discreetly and out of police view. In most cases it is said that bookie and customer never meet.

Of course, not every country has banned sports betting, and many sites based in other countries will happily accept Indonesian players.

These sites usually quote customers in local odds and deal in local currency, so it may become important for Indonesians to get familiar with American, HK, or European odds and get used to exchange rates in dollars or euros.

Also, most books that accept Indonesians are available in English only, so that may cause inconvenience in some cases. Of course the trade-off may be better odds and more secure payments than a shady underground operation.

Advice for Betting in Indonesia

If you are in Indonesia, make sure you are careful about who you bet with and against. Again, it is questionable in the eyes of the law and this causes some unique situations and problems, but as always there are opportunities as well. It makes sense to become familiar with American odds, online calculators, and the English language if you plan on betting in Indonesia.

Of course if you are just visiting you may decide to give up sports betting while you are on vacation, but what’s the fun in that?


What are Indonesian odds?

Also known as Indo odds, Indonesian odds represent the likelihood of something happening and something not happening. They are similar to American odds – they are the same odds just divided by 100. American odds of +115 are expressed as 1.15, and the plus sign is always implied if it is not there.

How do you read Indonesian odds?

Indonesian odds are similar to American odds, with plus (+) and minus (-) signs used to represent the favourite and underdog. Indo odds of +300 represent an underdog and mean you’ll win Rp 300 for every Rp 100 bet. Odds of -300 represent the favourite and mean you must stake Rp 300 to win Rp 100.

How do you convert Indonesian odds to decimal odds?

If you’re converting positive Indo odds to decimal odds, simply add 1. Therefore, Indo odds of 1.5 equal 2.5 as decimal odds. If you’re converting negative Indo odds to decimal odds, divide by the Indo odds and add 1. Here’s the formula to convert Indo odds of -1.5 to decimal odds: 1 / 1.5 = 0.67 + 1 = 1.67.

How do you convert Indonesian odds to fractional odds?

If the Indo odds are positive, remove the ‘+’ symbol and any redundant zeros from the odds and add ‘/1’ to the end. Therefore, Indo odds of +3.0 become 3/1. For negative Indo odds, remove the ‘-‘ symbol and any redundant zeros, then add ‘/1’ to the beginning and multiply both numbers by the same number so they come whole numbers. Therefore, Indo odds of -4.25 become 4/17 as fractional odds.
