What are sports betting odds?

It does not matter what UK betting site you use; a common feature that you will find at any sportsbook is betting odds. Sports betting odds are a numerical representation of the likelihood of a particular event occurring. When using UK sportsbooks, the odds are determined by the sportsbook based on several factors, including market trends and historical data.

In a nutshell, sports betting odds serve two primary purposes: they indicate the probability of a specific event occurring and how much money you stand to win if your bet is correct.

Sports betting odds explained: The three most popular odds displays

Depending on the betting site that you use, the odds will be displayed in either decimal or fractional format. However, you have the option of changing the display to what you prefer, even if that is American odds. Generally, there are three main displays available at licensed and regulated sportsbooks: decimal, fractional and American.

Below is a table that explains how these odds are structured and displayed, and thereafter, we will unpack why each is so popular among bettors.

1. Decimal betting odds

In the UK, regardless of whether it is tennis odds or golf odds, the decimal format is one of the most commonly used odds displays. Decimal odds are popular because they are simple to calculate the suggested returns on a winning bet. When working out the potential returns on your bets (including the stake), you multiply your bet by the decimal value.

In the example in the table, Barcelona are priced at 1.80 to win, while Real Madrid is priced at 5.00. A £10 bet on Barcelona to win will give you £18 (£10 x 1.80), and a £10 bet on Real Madrid to cause the upset will return £50 (£10 x 5.00).

2. Fractional betting odds

Fractional odds are another popular choice for UK bettors. However, unlike decimal odds, there is more calculation to do to figure out your potential returns. The numerator (the first number in the fraction) is what your expected profit would be based on if the denominator (the second number in the fraction) were your wager. Some bettors prefer fractions as it is easy to figure out whether you can get a bigger return, especially if the numerator is much higher than the denominator.

Let’s say the Champions League odds for Barcelona vs Real Madrid have Real Madrid at 4/1 to beat their rivals. This means that your £10 wager will return £40 in profit should Los Blancos win, and a total return of £50 (stake included). On the other hand, if Barcelona were to win at 4/5, then your £10 wager will return £8 in profit, and a cumulative return of £18.

3. American betting odds

Finally, there is the American odds display, which is rarely used at UK sportsbooks. Generally, low-priced favourites below even money have a (-) before the odds, while the underdog above even money will have a (+) before the odds. One of the main advantages of using the American display is that it is easy to see which team is the low-priced favourite of a specific fixture.

Back to the example from the table, and since Barcelona is -120 to beat Real Madrid, you would have to bet £120 to win £100 in profit, and get back a total return of £220 (stake included). However, if Real Madrid wins the match at +400, then a £100 winning bet will give you £400 in profit, and a total return of £500 (stake included).

Why is there a mixture of high and low odds?

When browsing the different UK betting sites, you will notice that the odds could be different, and while some sites may have slightly better odds, others will have slightly lower odds. There are several reasons for this, including public opinion and market perceptions, the bookmaker’s margin, and the data feed used by the betting site.

However, what you will also notice is a mix of high and low odds across different sporting events. As we covered, generally, the underdogs for an event will have much higher odds, while the favourite odds will be low-priced and below even money. Besides the match winners markets, there are also several other bet types with a mix of high and low odds. Alternative lines for totals and handicaps feature both high and low odds, as do outrights, live betting and player and team props.

Tips when analysing betting odds and placing wagers

If you need help with analysing betting odds, we have shared a few betting tips below that you can follow:

• When claiming any betting bonuses, make sure you diarise the key bonus terms, including the relevant odds restrictions. Sometimes, there will be a minimum odds limit that you must meet when placing qualifying wagers with your free bets or real money.
• Always do your research to find the best available sports odds, such as those offered by Matchbook Sportsbook or The Pools Sportsbook. Take some time to visit the different sportsbooks and see if any site has better odds than the others.
• Enhanced odds are a type of sportsbook promo, and some of the best UK betting sites will offer enhanced or boosted prices on specific events. It is a good idea to claim these promos, as you will be given a better price than the industry standard.
• Never back teams solely based on their odds. You must always do your research before placing any wagers. When researching sports bets, double-check the weather conditions, review team and player form, check for any key players carrying injuries, and compare historical results between both sides.

Conclusion - The best UK betting sites have competitive odds on all markets

It does not matter whether you are searching for Premier League odds or Super Bowl odds; when you use licensed and regulated UK betting sites, you will always find the latest sports betting odds. Since there are so many UK sportsbooks in the industry, the good news is that you will find competitive odds that are fairly priced and reflect the industry standard.

However, you should also be aware that different prices are available at various betting sites, and some sites offer better odds than others for a specific event. Therefore, you need to do your research in advance to find the best available price before placing your bets.
