Betting odds explained – What do odds represent?

Bookmakers present the betting odds either in decimal format, fractional format or American format. Even though they look different, they mean the same thing. All the odds are often represented through the probability of things happening. So, how betting odds are calculated by bookmakers who measure the probability and put it against the risk to give the betting odds. Betting is also assessing the probability or a chance happening so that the bookmakers can use the odds which translate the implied chances into usable forms through betting offers.

Understanding of betting odds and how betting odds are calculated will help you in comparing the odds between bookmakers.

To expand your understanding of odds, you also should know the basics of probability. With good knowledge about the probability calculations and comparison of odds provided by the bookmaker, you can begin taking decisions about what type of bet you should make, what you should be betting on, when you should be betting and how much stakes you should either make or take.

A Quick Introduction to Betting Odds – How to calculate Betting odds?

Decimal and Fractional odds seem confusing at first if you are not familiar with betting, betting types, and betting terms. As mentioned above, betting odds are used to present the favour of a result, while it helps you in understanding how much you can win as well. The odds are usually written in fractional format (say 2/1) or decimal format (say 2.0). Betting odds can also be applied to any betting market that has an outcome and is mostly calculated in sports betting markets, entertainment markets or political markets. These odds also measure the result probabilities like the results of a game, the winners of a reality TV show or if a particular party is getting a majority in an election or not.

How do Betting Odds work?

Apart from knowing how betting odds are calculated, it is important to know the types of odds. Betting Odds are commonly identified in three different formats – Long, Short and Even.

  • Even odds: When a particular result has equal odds of it to happen or not, then it is given the even odds. The even odds are usually represented as 1/1 in fractional format or 2.0 in decimal format. The winnings of a bet with even odds would be the same as the stake. For example, if your stake is £1, your winning is also £1. If your stake is £10, your winning is £10, and you will get a total return of £20.
  • Long Odds: If something is less likely to happen, they are known as long odds. The long odds represent the potential to win than you can win with even odds. At the same time, the risk of losing is also higher with even odds. For example, if there are 10/1 long odds, you can win £10 for £1 as your stake. The winnings in long odds clearly exceed the stake. Similarly, a winning bet of £10 would give you £100 with 10/1 odds giving you £110 in total.
  • Short odds: If something has a higher probability of happening, it will have short odds. While short odds will give you positive results, the winnings are smaller on these bets. Therefore, a player has to stake a higher amount for bigger returns. For example, if you have 1/10 short odds, you will win £1 for £10 you stake and get around £11 as a return.

How to calculate Betting Odds

Once you understand how betting odds are calculated, you can examine the probabilities in a more detailed manner, helping increase your chances of winning you bets by finding the best odds. Once the probability is calculated, you can turn the number into odds through a simple and straightforward process. Decimal odds – one of the three main formats is mainly used by most of the bettors. As a bettor, you can use the simple equation to arrive at the decimal odds through the toss choice.

1 / probability for your result: The decimal odds for a coin landing on heads is 1, and it should be divided by the probability of its occurrence (which is 0.5) – giving you the decimal odds of 2.0. Through this process, you can simply take the betting odds and reverse engineer them with an inverse equation to turn the probability into odds.

1/decimal odds = probability: By taking the needed knowledge and working out the probability for the toss, you can get the aggregate of the implied probability for both the results in the toss, which is 100%. (0.5/1+0.5/1)*100 without surprises as an event will have odds say 1 (100/100). You can perform the same calculation for odds and compare them with a given bookmaker to produce odds that are greater than 100%.

Calculating a Bookmaker’s margin:

In simple language, the odds do not actually reflect the likelihood of the results that are concerned with the event. The amount by which the probability actually diverges from the 100% odds is the bookmaker margin – the amount that has been added by the bookmaker to the specific market. Bookmarker margin is an important element in reading the odds as it tells you a lot of information about the bookmaker. A value-seeking bettor uses this information and highlights the actual cost of the bet with respect to a bookmaker. By using the probability and the shared bookmaker origin, it would be easier for a bettor to place intelligent bets. Calculating odds is difficult, so you don’t actually have to do it all by yourself. You can find a quick way to analyze these margins using our Margin Calculator tool as well.

Using Odds to calculate your payout:

Calculating betting odds will open a new world to bettors as they can calculate the value of the payout. Based on the betting value and the odds, one can decide if a bet is safe to make or not.

Your stake X decimal odds: So if you are making a €10 bet with 2.0 betting odds, your returns include 2.0x €10 = €20. By calculating the probability and understanding the odds, you can evolve as a bettor. You will know your frequency for an event, start modelling the odds, compare the bookmakers and choose the best bookmaker to make a specific bet. When the two betting types diverge, you can turn this into favour by generating the profit, which is the main aim for the bettor. Now that you have known the whole process of calculating the betting odds, you can take advantage of low margins and make informed decisions in betting.
