When converting fractional odds to decimal odds, the calculation requires you to add the multiplier + 1 (which acts as the stake). For instance, 6/4 express in decimal odds is 1.5 + 1 = 2.50 (decimals always expressed to two places).

Using this converter is easy. Simply enter the fractional odds into the box that states Fractional Odds. Fractional odds look like 2-1 0r 13/5. Press convert and the. Decimal odds are the easiest to calculate compared to other odds types. Bettors just need to take their stake x odds to equal their payout amount. For instance, if you bet $100 at 2.0 decimal odds, you’d get $200 if your bet won, your $100 stake back, plus your profit of $100.

While most gamblers are interested in converting odds to probability in order to discover the probability% based on the decimal odds offered by the bookies, there are also many gamblers who need a probability to odds calculator. The MOG Probability To Odds Calculator can be useful when you analyze the winning probability% of different events and you want to convert those findings.

Around the world, there are several methods used to present betting odds. Ultimately they all represent the perceived percentage chance of success, but to the uninitiated the different odds displays can be confusing. Here we break down just what each of the popular methods mean:

Decimal Odds

Decimal odds are widely used around Europe and are the display format of choice for the betting exchanges around the world. They are also incorporated in Asian Handicap betting which is quickly becoming a popular way of gambling on football and other events, and, to many, decimal odds are the most straightforward representation of probabilities. The odds that are presented illustrate the return that you will receive if your bet is successful, to a unit stake of 1. Therefore, if the decimal odds on a football team are 4.50, and you stake £10, the return if the bet goes in would be £45 and the profit would be £35 (4.5 – 1, multiplied by stake).

Any decimal odds that are less than 2.0 indicated that the selection has a more than 50% chance of success, as the outlay is greater than the return. For instance, a bet of £50 on a 1.60 chance would return £80 (£50 stake + £30 profit).

Fractional Odds

Fractional odds have been the choice in the UK for centuries. They are still used today on racecourses, football coupons and betting adverts. To a beginner, fractional odds may seem a little more difficult to grasp that decimal odds.

Examples of fractional odds include 7/4, 4/1, 5/2 and 11/4. In order to obtain ‘the multiplier’, the top number should be divided by the bottom number. For instance 7 divided by 4 gives 1.75. This 1.75 multiplied by your stake will be the profit on the bet, but don’t forget to add on your stake to get the total return.

E.g. £40 is placed on a horse whose odds are 5/2. The horse wins.

Stake: £40
Multiplier: 5 divided by 2 = 2.5
Profit: 2.5 x 40 = £100
Return: Stake (£40) + Profit (£100) = £140

When converting fractional odds to decimal odds, the calculation requires you to add the multiplier + 1 (which acts as the stake). For instance, 6/4 express in decimal odds is 1.5 + 1 = 2.50 (decimals always expressed to two places)

If the number at the bottom of the fractional odds is larger than the number at the top, then the selection is ‘odds on’ – it is deemed to have more than a 50% chance of success. The larger the bottom number compared to the top number, the higher the probability.

Moneyline (US) odds

For some events such as horse racing, US betting sites adopt fractional odds. However for many sports and markets such as American Football, Boxing etc. ‘moneyline’ odds are used. These moneyline odds are generally used for an event with two outcomes.

Moneyline odds are worked out to a bet of $100. If the figure for a team is positive, then it refers to how much profit will be made based on a $100 dollar wager. For example, if the Denver Broncos were available for a match at +120, for every $100 staked, the profit would be $120 and the total return would be $220. Positive odds are used for the outcome which is deemed to be less likely.

A negative figure on the moneyline indicates a betting favourite and indicates how much needs to be staked to win $100. Betting on a Floyd Mayweather fight (where he is always a heavy favourite), punters are likely to see odds of -700 for the undefeated star. This means that $700 will have to be staked to make $100 profit. The total return would be $800.

Even money shots indicate that there is a 50% chance of success and in theory could be expressed as -100 or +100, as ultimately $100 staked at these odds equals $100 profit. Read about US Moneyline odds in more detail.

Hong Kong odds

Hong Kong odds are unsurprisingly adopted by many Asian bookmakers. The odds are fairly simple to work out in format and are a cross between decimal and fractional odds in their presentation, in that they exhibit the net return similar to fractional odds, but are presented in a decimal format.

To understand Hong Kong odds, the punter should assume that they are placing a 1 unit bet on a selection. The odds reflect the profit that will be obtained from striking that bet. Any odds that are less than 1, indicate the bet is ‘odds on’ i.e. has more than a 50% chance of success.

E.g.

HK odds of 0.4 = 0.4 units profit for every 1 staked. (Fractional odds of 2/5)
HK odds of 5 = 5 units profit for every 1 staked (Fractional odds of 5/1)

Indonesian odds

Indonesian odds follow the same format as US odds, but just use a different stake to illustrate the probabilities of each outcome. Whereas with US betting odds returns are calculated a stake of 100, in Indonesia, they are calculated to a stake of 1. Again, odds with a – sign before them demonstrate how much is required to be staked to win 1 unit, whilst the + sign is disregarded for the ‘outsider’ bets which show how much profit can be obtained for a 1 unit stake. Read further about Indonesian odds here.

E.g:

Manchester United are playing Newcastle at home. Manchester United are available at Indonesian odds of -3.0 to win the game. This means a 3 unit bet will give a 1 unit profit and total return of 4 unit.

Andy Murray is playing Rafa Nadal in France on a clay court. Murray is available at Indonesian odds of 2.25 to win the match. This means for every 1 unit staked, if Murray wins, 2.25 units will be made in profit, with a return of 3.25.
Even money bets are quoted as 1.00.

Malay odds

Malay odds are effectively the opposite of US odds. They also work on positive/negative system of display, but in reverse to that adopted in America. If the number is positive, then it indicates what you will receive for an outlay of 1 unit. For example, odds of 0.75 would indicate that for 1 unit stakes, 0.75 units profit would be derived. When the odds are negative, they indicate the bet has a less than 50% chance of success. So a bet which was -0.05 would require just 0.05 units to be staked to win 1. An even money bet is indicated as 0. Read more on this here.

E.g.

1. A horse is available at odds of -0.40. This would require an outlay over 0.4 units to win 1 unit. In decimal terms this equates to odds of 3.5

2. Arsenal are at home to Ipswich in the FA Cup. Arsenal can be backed at 0.25. This means for every 1 unit placed on Arsenal, 0.25 units profit will be made.

There is a lot of jargon used in sports betting and it can be quite confusing, especially for a novice, but once you get to grips with the basic terminology, your betting experience will be enhanced. The first thing that any punter needs to do is understand how the odds work and what they mean.

Decimal To Odds Calculator

Many betting websites - including the Betfair Exchange - now use decimal odds as standard, so let’s take a closer look at this popular format.

The purpose of sports betting odds

Odds are a numerical way of describing the probability of an outcome occurring. The odds are calculated by bookmakers like Betfair and Paddy Power in a way that allows them a small profit margin. For example, on a 50/50 coin toss, a bookmaker might offer odds of 49/50. If they get an equal amount of money bet on heads and tails, they would be guaranteed a small profit whatever the outcome.

What are decimal odds?

Decimal odds are a way of displaying odds in an easy to understand way.

In the above example, where the bookmaker offers odds of 49/50 on a coin toss, the odds are shown as a fraction. If we showed the same odds in decimal format, they would look like this:

• Decimal odds: 1.98

So, if a punter placed a stake of £1 on this bet and it was successful, they would receive £1.98 back, achieving a profit of 98p.

In decimal odds, odds-on selections will be expressed as values between 1.0 and 2.0

Many websites use the decimal format as standard when displaying the prices of sporting events. In fact, decimal odds are commonly used all over Europe. They are popular because they are so easy to understand, displaying the total return from a 1 unit stake.

As the unit stake is always included, decimal odds always have a value greater than 1.

Here is another example of how simple it is to read decimal odds:

• Odds: 6.0
• Stake: £1
• Winnings: £5
• Total return: £6

Decimal vs. fractional odds

Punters in the UK and Ireland might not be as familiar with decimal odds. In those regions, it is more common to see fractional odds such as 5/1 or 9/2. Fractional odds basically describe the winnings from a theoretical stake.

Fractional odds example:

• Odds: 5/1
• Stake: £1
• Winnings: £5
• Total return: £6

Where the odds are 50/50, the odds are described as Evens rather than 1/1.

The advantage of decimal odds

Fractional odds can sometimes be confusing as the calculation can produce very large numbers. For example, where the decimal odds are 1.46, the fractional equivalent would be 23/50. In this case, it is much easier to calculate the return from a £1 stake by using the decimal odds format.

In addition, fractional odds can be confusing when the probability is very high. For example, when decimal odds fall below 2, the fractional equivalent suddenly takes a different appearance as the second number becomes larger than the first number. Therefore, it is possible to have fractional odds of 2/1 and 1/2 and this can be a little confusing for novice punters.

Decimal vs. moneyline odds

Moneyline odds (also known as US or American odds) are used by bookmakers in America. The odds are presented in either a negative or positive format depending on the probability.

Moneyline odds are used by bookies in America

Positive moneyline odds show how much would be won from a $100 stake. In a sporting event involving two teams, the underdog always has a positive moneyline.

Positive moneyline example:

• Odds: +500
• Stake: $100
• Winnings: $500
• Total return: $600

Negative moneyline odds show how much would need to be staked to win $100. In a sporting event involving two teams, the favourite always has a negative moneyline.

Example

• Odds: -500
• Stake: $500
• Winnings: $100
• Total return: $600

If there is no clear favourite and the odds are 50/50, the moneyline is displayed as +100. Using the positive rule, a $100 bet would then return a $100 profit.

Why is understanding odds important?

Understanding how to read odds is a vital part of sports betting. If you do not know how to read the odds, you will never know if you are getting good value or what your potential returns might be.

In theory, decimal odds are the easiest to understand and many punters have switched to using decimal odds after years of using the fractional format. Decimal odds can be read at a glance and do not require any tricky calculations.

Most betting websites - including Betfair and Paddy Power- have a settings menu where you can change the way that odds are displayed. This means you can choose the option that suits you best. But even if you prefer to use fractional odds, it still makes sense to learn how to read decimal odds as they are becoming more widely used across the internet.
