# Fractional Odds in Sports Betting Explained

Odds is one of the fundamental concepts in sports betting. They are what determine how much money you can win if you place a bet on your favorite team, athlete or sport. Therefore, it’s important to understand how odds work, in their different formats.

# The History of Fractional Odds

Modern sports betting was born in the United Kingdom, where people started to bet on horse races around 1780 in the 18th century. Since that time, the British use fractional odds, and not only in horse races but also in football, cricket, and many other sports. In this article, Oddshero will explain everything you have to know about fractional odds, which is also called British odds. It might look complex, but if you want to calculate your total profit using fractional odds, you will be able to do so after you have read this article. At the end of the article you can find a table which shows the conversions between fractional to decimal odds.

# 5 Key Takeaways

1. Odds is a way to measure the probability that an event will happen in a sports game. The advantage of using odds over probability is that it shows how much you can profit if you place a bet on the given event. For example Arsenal to win against Manchester United.
2. Fractional odds is one of the most used odds formats in the betting world. They express the relation between your stake and a possible profit. The numerator represents “how much you will win”. The denominator expresses the value of your stake.
3. Fractional odds can be inverted like this: 2/7. That means there is a strong favorite in en event.
4. In general we recommend using decimal odds over fractional odds! Because the bookies will often shave off some decimal points through rounding compared to using decimal odds. So you are leaving money on the table by not using decimal odds for your sports betting.
5. For converting from decimal odds to fractional odds, we recommend using a conversion table which you can find at the end of this article or a conversion calculator.

# “What are the odds?”

“The odds of what match?” No, we mean the concept of odds. It’s better to know about it. Anyway, odds are the description of the rating that shows the amount that a bookmaker will pay to you for each euro that you have deposited as a bet; in case your prediction about the outcome was right.

Likewise, in a more deep definition of odds, Wikipedia says: “Odds are a numerical expression, usually expressed as a pair of numbers, used in both gambling and statistics. In statistics, the odds for or odds of some event reflect the likelihood that the event will take place, while odds against reflect the likelihood that it will not. In gambling, the odds are the ratio of payoff to stake, and do not necessarily reflect exactly the probabilities”.

Thus, and in a conceptual summary, the odds will be the amount by which our bet will be multiplied for a certain sporting event, this being more or less high depending on the difficulty rating of hitting the result. Therefore, greater difficulty will result in a larger fee.

# How do fractional betting odds work?

Fractional odds are expressed as 10/1 or 12/2. But what do the numbers mean? It’s more simple than it looks. The numerators, in this case, 10 and 12, represent “how much you will win”. On the other hand, the denominators, 1 and 2, express “how much you stake”. Thus, if you place €1 on a bet with the odds at 10/1, your profit will be €10 plus the value of your initial stake €1.

It must be said as well that sometimes, the odds can be inverted like this: 2/7. It could be confusing, but not really. This just means there is a strong favorite competitor to take the win in a sporting event. So if 2/7 means that your profit will be €2 if you bet €7.

Let’s see some examples with both cases:

## Example 1: West Ham vs Tottenham Hotspur

With the international break coming, all the big leagues in European football will return to action after 20th November. On Saturday 23rd, West Ham and Tottenham will face at London Stadium. Hammers are the home team and the odds for a West Ham win are 14/5, so as you can see if you bet on a home victory, for each €5 your earning will be €14.

Nevertheless, how do you calculate the potential return from fractional odds? See below.

[(Your stake/denominator)x numerator) + stake]

Let’s say you bet €50 at 14/5:

[(50/5)x 14)+ 50]=190.

So, if you bet €50 at 14/5 odds your profit will be €190. Nice for those who will bet for the Hammers.

Now let’s take a look a the second scenario:

## Example 2: Crystal Palace vs Liverpool

The same Saturday 23rd, the current leaders of the Premier League, Liverpool, will visit Crystal place at Selhurst Park. The reds will be looking forward to taking the three points to maintain or extend their advantage, and they strong favorites to win. The odds for Liverpool defeating the eagles are 5/12.

Thus you bet €50 on LFC to win, let’s make the operation.

[(50/12)x 5)+ 50]= 70.83

€70.83 will be your profit. And clearly, Liverpool are the favorites according to the current odds.

# Key Takeaway

Fractional odds are pretty simple to understand, but in general we recommend using decimal odds, because as you can see in the odds conversion table below, the bookies will often shave off some decimal points through rounding compared to using decimal odds. So you are leaving money on the table by not using decimal odds for your sports betting.
