How Do Malaysian Odds Work? Explained for Aussies

Confused by American betting odds? Learn how they work, what the numbers mean, and easily convert them to Australian Decimal odds for your next bet.

What Are American Odds?

American odds, also known as ‘moneyline odds,’ are most commonly used in the United States. They are presented with a plus (+) or a minus (-) sign before a number, like +200 or -150. These signs tell you two crucial things: which team or player is the favourite, and which is the underdog.

Understanding the Plus (+) and Minus (-) Signs

  • Minus Sign (-): When you see a minus sign, it indicates the favourite in a contest. The number after the minus sign tells you how much money you need to wager to win $$100. For example, -150 means you’d need to bet $$150 to win $$100 profit.
  • Plus Sign (+): A plus sign indicates the underdog. The number after the plus sign tells you how much money you would win if you wagered $$100. For instance, +200 means a $$100 bet would win you $$200 profit.

Calculating Your Payouts (AUD)

Let’s look at how to calculate your potential winnings in Australian Dollars.

For Odds with a Minus Sign (-)

When dealing with a favourite (minus sign), the odds tell you how much you need to stake to win $$100 profit.

  • To calculate profit: Profit=(Stake/Odds Value)×100
  • Example: You see odds of -200 and want to bet $$50.
    • Profit=(50/200)×100=0.25×100=AUD 25
    • Your total return would be your initial $$50 stake plus the $$25 profit, equalling $$75.

For Odds with a Plus Sign (+)

When dealing with an underdog (plus sign), the odds tell you how much you can win on a $100 wager.

  • To calculate profit: Profit=(Stake/100)×Odds Value
  • Example: You see odds of +300 and want to bet $$50.
    • Profit=(50/100)×300=0.5×300=AUD 150
    • Your total return would be your initial $$50 stake plus the $$150 profit, equalling $$200.

How to Determine Stake for a Desired Payout

Sometimes you know how much you want to win and need to figure out your stake.

  • For Odds with a Minus Sign (-) (e.g., -150 to win $$100 profit):
    • Required Stake=(Odds Value/100)×Desired Profit
    • Example: You want to win $$100 on odds of -150.
      • Required Stake=(150/100)×100=AUD 150
  • For Odds with a Plus Sign (+) (e.g., +200 to win $$100 profit):
    • Required Stake=(100/Odds Value)×Desired Profit
    • Example: You want to win $$100 on odds of +200.
      • Required Stake=(100/200)×100=AUD 50

Converting American Odds to Decimal Odds (AUD)

Since Australians are most familiar with decimal odds, knowing how to convert American odds is helpful. Decimal odds are straightforward: they represent the total return (including your stake) for every $$1 wagered. For example, decimal odds of 2.50 mean a $$10 bet returns $25($10 stake + $$15 profit).

Conversion Formulas:

  • For Positive American Odds (+): Decimal Odds=(American Odds/100)+1 Example: American odds of +200 Decimal Odds=(200/100)+1=2+1=3.00
  • For Negative American Odds (-): Decimal Odds=(100/∣American Odds∣)+1 Example: American odds of -150 Decimal Odds=(100/150)+1≈0.667+1=1.67 (rounded to two decimal places)

Why Do Odds Change? (Implied Probability)

Odds aren’t just arbitrary numbers; they reflect the implied probability of an event happening. Bookmakers calculate these odds based on various factors, including team form, injuries, historical data, and public betting patterns. When you see odds move, the perceived probability of an outcome has shifted.

  • For Positive Odds (+): Implied Probability=100/(American Odds+100)×100 Example: +200 Implied Probability=100/(200+100)×100=100/300×100=33.33%
  • For Negative Odds (-): Implied Probability=∣American Odds∣/(∣American Odds∣+100)×100 Example: -200 Implied Probability=200/(200+100)×100=200/300×100=66.67%

Understanding implied probability helps you assess whether the odds a bookmaker offers represent good value.

Frequently Asked Questions (FAQs)

American odds use positive (+) and negative (-) signs to show potential winnings or the required stake, mainly used in the USA. For example, +200 means you win $$200 on a $$100 bet, while -150 means you bet $$150 to win $$100.

For favorable odds (+), use the formula: (American Odds / 100) + 1. For unfavorable odds (-), use: (100 / |American Odds|) + 1. All Australian bookmakers use decimal odds, so converting helps you easily understand your potential total return.

+150 means that if you bet $$100, you would win a profit of $$150. Your total return would be $250($100 stake + $$150 profit).

-200 means you need to bet $$200 to win a profit of $$100. Your total return would be $300($200 stake + $$100 profit). This indicates the favourite.

Neither is inherently "better." Plus odds (+), representing underdogs, offer higher potential payouts for lower stakes but are less likely to win. Minus odds (-), representing favourites, offer lower payouts but have a higher probability of winning. Your choice depends on your risk tolerance and betting strategy.

Many international sportsbooks cater to a global audience, including the large US market, where American odds are standard. Understanding them allows you to access a broader range of betting opportunities.

Conclusion

Navigating American odds doesn’t have to be confusing for Australian bettors. By understanding the simple rules of the plus and minus signs, how to calculate your potential winnings, and how to convert them into familiar decimal odds, you’re well-equipped to make informed betting decisions on international platforms.

Remember, betting should always be responsible. Now that you’re an expert in American odds, go forth and bet smart!
