Over time, you can increase your returns markedly by betting with different bookmakers to ensure you get the best odds possible on a market. The advances in AI, computing power and processing speed mean it is now possible for bookmakers to offer odds on markets within a fraction of a second, or to update markets in real time (which is what happens in In Play betting). Many people now use bet calculators to work out their returns for the different odds formats. Odds are scalable, so if you placed a $10 bet at odds of +270, then your bet would see you return $27 in profit, plus your $10 stake back.
For this we are going to use three equivalent odds (4/1) to show you how to understand and calculate odds and what the calculation is for each format of odds in common usage today. Some calculators may even offer options to convert into less commonly used formats. They use a series of positive odds or negative odds (numbers) to show how much you could win or need to wager to win $100. This is the more traditional odds format that has been used for many years, notably in the UK but also in many other countries around the world. Putting these odds into the odds converter will bring the calculation to a probability percentage of 33.33 per cent. You can use an odds converter if you read odds formats that you’re unfamiliar with and want to translate them into a format that you understand.

If you calculate the book percentage on a bookmaker’s odds it will normally be over 100%. In reality, the correct odds of all the possibilities add up to make a 100% book (identifying the correct odds for each possibility is the tricky bit)… The probability of an event happening can be expressed as a percentage, for example, if you toss a coin the probability of heads or tails is 50% or evens for each.
