What are Fractional Odds?

Fractional odds are one of the two most popular ways to express the probability of an event's outcome in the UK and Europe. Fractional betting odds are displayed with a numerator over a denominator (2/1).

You don't have to be a math wizard to understand how fractional odds work.

So, how do fractional odds work? Let's explore this question deeper to give you more betting knowledge. Remember, knowledge is power, and power is profits.

How do you read Fractional odds?

Bookmakers traditionally display prices using fractionals. Today, however, they use decimal number and different methods.

For many people, fractional betting odds are the simplest way to determine their winnings based on their stake.

The fractional odds of a sporting event display your potential winnings based on the amount you stake on the bet. Let us look at an example to explain this further.

If you stake a £1 bet on Manchester City to win at 5/1, it will pay out £6 if it is successful (£5 profit plus your £1 stake).

The top number, the numerator, is the amount you will win based on the bottom number, the denominator. The bottom number is the amount of money you must stake to win the top number.

Fractional betting odds do not include the amount you bet. If you place a winning bet, the bookmaker will return the stake and the profits.

When calculating your net profit, before wagering, remember to add your original stake to the amount.

How Do you Convert Fractional Betting Odds into Potential Winnings?

It is simple to convert fractional betting odds into winnings. If you wager on Manchester United to defeat Manchester City at odds of 5/1, you are set to make £5 for every £1 you wager, if the bet is successful.

Therefore, we can calculate the positive value of the potential winnings by multiplying the number on the left by the number on the right.

For example, you wager on Manchester United to win at odds of 5/1. Instead of wagering £1, you stake £10. A winning bet would return £60 (£50 profit plus £10 stake).

Converting decimal odds to fractional betting odds into potential winnings can be more difficult based on fractional odds than decimal odds.

For example, if you bet on Chelsea defeating Crystal Palace at odds of 8/11, you would win £8 for every £11 you wager.

Do Fractional Betting Odds Calculate Probability?

You can calculate the probability of an outcome by using fractional betting odds. Let us take for example the Chelsea versus Crystal Palace example. Chelsea are at odds of 8/11 to win at full-time.

If you divide 8 by 11 (8/11), you will get the probability of the outcome occurring. The implied probability of Chelsea winning is 73%.

How Betting Odds Work

Odds are your betting selection's probability percentage or chance of winning a sporting event in the opinion of a bookmaker.

The odds also reflect the amount of money you will win if your bet is successful. Odds may differ depending on the sportsbooks.

What's the Difference Between Fractional Betting Odds and Decimal Odds?

Fractional betting odds are displayed as a fraction with the amount you will win on top and the amount you must stake at the bottom for those profits.

For example, odds of 2/1 mean you will win £2 on a £1 wager if the bet is successful.

Decimal odds, however, show the probability percentage and amount of money you would win for every £1 wagered. For example, decimal odds look like 3.00.

These decimal odds mean that a £1 stake would result in a £2 profit for a successful bet. Unlike fractionals, decimal odds include the returned stake.

Fractional Betting Odds or Decimal Betting Odds?

Fractional odds and the decimal form of odds are popular in the UK and Europe. The use of these different odds formats comes down to personal preference. Once you find an odds type to display that you are comfortable with, you are unlikely to change.

How Do You Convert Fractional Betting Odds into Decimal Odds?

Converting fraction odds to decimal odds is simple. Just divide the number on the left by the number on the right and add one. For example, if you have the odds of 2/1, simply divide the odds of 2 by 1 and add 1.

(2/1) +1 = 3.00

What's The Difference Between Fractional and American Odds?

American odds are much different than fractionals. They are typically used by sports bettors in North America.

American odds are based on winning or wagering £100 on a bet. The odds are represented by a plus (+) or minus (-) sign. The plus and minus signs indicate which team is the favourite and the underdog.

What are Moneyline odds?

Moneyline odds are the same as American odds. The two terms are often used interchangeably by some punters and bookies.

How Do You Convert Fractionals into American Odds?

It is slightly more complicated to convert fractionals to American odds than fractionals to decimals.

For fractions greater than 1, use the formula: (fractional value) x 100 = American odds.

For fractions under 1, use the formula -100 / (fractional value) = American odds.

What is the Difference Between Decimal Odds and Implied Probability?

Decimal odds express a simple value that can be multiplied by your bet amount to calculate the potential profit and overall return.

Implied probability, also known as implied odds, explains what the bookmaker expects the outcome of an event to be.

For fractionals: denominator / (denominator + numerator) x 100 = implied probability

How Do You Convert Fractionals Into Implied Probability?

To convert probability and fractional odds to implied probability, use the following formula:

denominator / (denominator + numerator) x 100 = implied probability

Which Countries Use Fractional Betting Odds?

Fractional odds are used worldwide but are most common in the UK and Europe. Sportsbooks in the UK display their odds using fractional numbers.

Why Do Some Countries Use Fractional Betting Odds?

Fractional odds are often considered the traditional way to display bookmaker odds. Decimals have become popular, but plenty of punters still use fractional odds because they started out using them.

Are Fractional Betting Odds UK Odds?

Fractional odds are also called UK odds. This is because the odds format is commonly used in the UK. Ireland and most countries in parts of mainland Europe also use this odds format.

Do Betting Sites Give you the Option to Use Fractionals?

Online betting sites allow bettors to change their odds display. Before wagering, change the display to their preferred style.

Which Is the Best Odds Format?
