About International Odds Displays

Most online sportsbooks quote odds in three major formats: US Style (Moneyline), European Style (Decimal), and Traditional Style (Fractional). Additionally, Asian oriented sportsbooks may use Hong Kong, Indonesian, and Malaysian styles. US-style odds are either positive or negative numbers. A negative number represents the amount needed to risk to win 100 units, while a positive number represents the amount a player would win for risking 100 units. Decimal-style odds are numbers greater than 1, indicating the amount returned if the bet wins including the initial stake. Fractional-style odds are displayed as a fraction showing the payout relative to the stake. Hong Kong-style odds are positive numbers greater than 0, Indonesian-style odds are numbers greater than 1, and Malaysian-style odds are numbers no greater than 1. Each style has its own way of representing odds and payouts. Regardless of the format, the odds imply a win probability, which determines whether a bet is good or bad.

Why Use an Odds Converter?

Betting odds are commonly displayed in various formats, so it’s useful to know how to easily convert them to your preferred format. American odds are favored by US bettors, while UK bettors typically use fractional odds and decimal odds are popular in Europe. However, fractional odds are commonly used in US horse racing. Some betting articles may show odds in decimal format, which can simplify calculating parlays. It’s also important to be aware of Asian formats in certain cases.

Understanding how to convert odds, such as NFL odds, allows you to manually make calculations. However, this can be prone to errors and time-consuming. It is more efficient to use a betting odds converter to quickly switch between American, decimal, fractional, and probability odds. Bookmarking this page can assist in successful sports betting by helping you determine potential profits based on your bet amount.

How to Use the Odds Converter

Input the odds you want to convert into any of the boxes in the betting odds converter and click “Convert.” The tool will then show you the equivalent odds in various formats. For instance, entering American odds of -125 into the US odds box will display decimal odds of 1.8000, fractional odds of 4/5, Hong Kong style odds of 0.8000, Indonesian style odds of -1.2500, and Malay style odds of 0.8000, with an implied probability of 55.56%.

Understanding the Different Odds Format

The most frequently used formats are American odds, decimal, and fractional, but Asian sportsbooks may also use Hong Kong, Indonesian, and Malay odds. Keep reading to understand their meanings and potential profit levels.

American Odds

American odds are represented by a plus or minus symbol. A plus sign indicates the amount of profit you would make from a $100 bet if you win. For example, +150 odds mean you would make a $150 profit from a $100 bet. You would also get your original stake back, so your total return would be $250. The $100 figure is just a reference point – you can bet any amount you like. For example, a $20 bet at +150 would result in a $30 profit if successful, while a $5,000 bet at +300 would earn you a $15,000 profit if successful.

Positive odds start with a plus sign, while negative odds begin with a minus sign. Negative odds indicate the amount needed to be wagered in order to make a $100 profit. For example, American odds of -110 mean you must bet $110 to win $100, resulting in a total return of $210 if successful. Regardless of the amount wagered, a $50 bet at -200 odds would yield a $25 profit. When one team has negative odds and the other has positive odds, the team with negative odds is favored, while the team with positive odds is considered the underdog.

Decimal Odds

Decimal odds are commonly used in countries other than the US, UK, and Ireland to indicate the potential return on a bet. This figure includes the profit you could make along with the return of your original stake. For example, American odds of +200 would be displayed as 3.00 in decimal format. To determine your potential return, simply multiply your bet amount by the decimal odds. So, if you bet $100 at odds of 3.00, you could expect a total return of $300 if your bet is successful. This would consist of a $200 profit in addition to the return of your initial $100 stake.

If you bet $1 with decimal odds of 1.50, you would receive a total of $1.50 back ($0.50 in winnings and your $1 stake). Decimal odds can help calculate potential profits on parlays more easily. You can use our parlay calculator for both decimal and American odds, or convert the odds to decimal format manually. Give it a try with NBA championship and Stanley Cup odds!

Fractional Odds

Fractional odds, also known as traditional odds, are commonly used at sports betting sites in the UK and at horse racing betting sites in the US, such as Kentucky Derby betting sites. If you prefer American odds, it can be helpful to know how to convert fractional odds to American odds. Fractional odds are expressed as a fraction representing the payout relative to the stake. For example, if you see fractional odds of 4/5 at the Kentucky Derby, you would earn an $8 profit for every $10 staked. Fractional odds of 4/5 are equivalent to American odds of -125 and decimal odds of 1.80. Odds-on fractions are less than 1 and are equivalent to negative American odds.

When viewing fractional odds, the number on the left indicates the potential profit for every amount wagered on the number to the right. For example, odds of 7/4 means a $7 profit for every $4 bet. A $100 wager at 7/4 would result in a $175 profit, displayed as +175 in American odds or 2.75 in decimal format. American odds of +100 are often known as even money or evens in fractional odds, equivalent to 1/1, which can be easily converted using an odds converter tool.

Hong Kong Style

Hong Kong odds are comparable to decimal odds, but they do not factor in the return of the original stake. For example, decimal odds of 1.80 would be represented as 0.80 in Hong Kong style, and decimal odds of 3.00 would become 2.00 in Hong Kong style. This format indicates the additional units that would be won beyond the initial stake if the bet is successful. In the Hong Kong style, US odds of +200 would be shown as 1.00.

Indonesian Style

These betting odds are very similar to US odds. Negative odds indicate the amount needed to wager to win $1, while positive odds represent the profit from a $1 wager. In Indonesian style, US odds of -125 would be -1.25 and -400 would be -4.00. In Hong Kong style, positive odds do not start with a plus symbol, so +200 becomes 2.00 and +250 becomes 2.50. Indonesian and Hong Kong odds are the same when positive. Use a betting odds converter to explore more examples.

Malay Style

The betting odds are represented by numbers with an absolute value of no more than 1. Positive Malay odds are interpreted the same as Hong Kong odds. For example, if you see Malay odds of 0.5000, it means you would make a $0.50 profit for every $1 wagered (plus you would get your original $1 bet back). On the other hand, negative Malay odds indicate the amount a bettor needs to risk to win 1 unit. So, Malay odds of -0.5000 would require a bet of $0.50 to win $1. For instance, a wager of $100 at Malay odds of -0.5000 would result in a $200 profit.

Implied Probability

The calculator will consistently show the implied probability of success for every set of odds. For instance, +200 indicates a 33.33% probability, while -500 indicates an 83.33% probability. This implied probability reflects the likelihood that the underlying event must happen in order to justify those odds. This concept applies to various forms of betting, such as sports betting, horse racing, entertainment wagers, online casino games, sweepstakes casino bets, and any other type of wager. Bettors typically seek opportunities where the actual probability exceeds the implied probability odds, as these are considered favorable bets.
