The main difference being decimal odds consider your original stakebeing returned, whereas fractional odds are a display of your profit. Decimal odds of course, are just a simple multiplier to your original stake. If an event at odds of $5.00 wins, you will receive back 5x your stake.
- High odds suggest a low probability of something happening, while low odds suggest a high probability of something happening. For example, imagine a tennis player is +200 to win an upcoming match. This would be 3.00 in decimal odds, and 2/1 in fractional odds. The implied probability for these odds.
- Converting Fractional Odds to Decimal Odds: An easy way to convert fractional odds to decimal odds is to convert the fraction into decimal form and then add a 1. For example, 5/1 or five-to-one fractional odds would be 6.00 in decimal odds. 5 / 1 = 5+1 = 6.00.
- Decimal - 1 divided by the decimal odds, multiplied by 100 to give a percentage e.g. Decimal odds of 2 = (1/2). 100 = 50%.; Fraction - 1 divided by (the fractional odds plus 1), multiplied by 100 to give a percentage. Fractional odds of 3/1 = (1 / ((3/1) + 1)). 100 = 25%.; American: Positive odds - 100 divided by (the american odds plus 100), multiplied by 100 to give a percentage e.g.

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.
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 Odds To Fractional Odds Chart
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.
Converting moneyline odds to decimal or fractional odds is not always easy. However, the tools below can be used as a handy guide.
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.

Stake + profit = payout
The first thing to understand is the difference between payout and profit. When you put a bet on you give your stake to the sportsbook. If you win the sportsbook will give you your stake back and pay you your profit. You can’t count getting your stake back as profit because it was yours to begin with.

Decimal Odds To Fractional Odds Calculator
Decimal odds are the most common odds format in the modern era. Decimal odds are great because they are simple and let you do calculations easily. Think of it like the metric system, it is superior but some old timers and Americans stubbornly refuse to use it.
The odds will be your payout for every unit you stake. If the odds are 1.32 you will get back 1.32 m฿ for every 1 m฿ you stake. This payout includes your stake of 1 m฿ and profit of 0.32 m฿. Here are a couple of examples with winning bets.
Decimal odds | 12 |
Stake | 1 |
Profit | 11 |
Payout | 12 |
Odds of 2.00 are “even money” because if you bet 1 m฿ you will either lose 1 m฿ or win 1 m฿.
The two other main odds formats are inferior and less common than decimal odds; they are fractional odds and American odds. These odds types are outdated and sportsbooks that show one of these odds types will also have the option to displaying decimal odds instead.
Fractional odds
Fractional odds are expressed as two numbers with a / in between like a fraction. Think of it as profit/stake. The first number is the amount you will profit if you stake the second number. This could also be expressed as the second number is the amount you would need to stake to profit the first number.
How Do You Convert Decimal Odds To Fractional Odds
Add both numbers together to see the payout you would get by staking the second number.
For example fractional odds of 4/6 means you would win 4 m฿ by staking 6 m฿. So if you stake 6 m฿ and win, your payout will be 10 m฿. This is made up of your 6 m฿ stake and 4 m฿ profit.
Fractional odds | 12/1 |
Stake | 1 |
Profit | 12 |
Payout | 13 |
Even money would be written as 1/1 but instead is called “evens”.
American odds
American odds are either expressed as a negative (-) number or a positive (+) number.
Negative (-) numbers are used for bets of less than even money, such as a favorite to win. A negative (-) number is how much you would have to stake to profit 100 units. Odds of -220 means you would have to stake 220 m฿ to win 100 m฿. So if you staked 220 m฿ and won, your payout would be 320 m฿, made up of your 220 m฿ stake and 100 m฿ profit.
American odds | -220 |
Stake | 220 |
Profit | 100 |
Payout | 320 |
Positive (+) numbers are used for bets at greater than even money such as for an underdog. Positive (+) numbers are how much you will profit if you stake 100 units. Odds of +480 means that if you stake 100 m฿ and win, you will profit 480 m฿. So your payout would be 580 m฿ made up of your 100 stake and 480 m฿ profit.
American odds | +480 |
Stake | 100 |
Profit | 480 |
Payout | 580 |
Even money could be written as +100 or -100.
