You can calculate the implied probability with decimal odds by dividing the odds by one and multiplying by 100. In this case it works as follows: (1 ÷ 2.1) x 100 = 47.6. There are plenty of online odds and betting calculators that can help you with such calculations. Fractional odds is the oldest and most traditional odds format around, and to date is still the most commonly used in the UK and Ireland. In the US, you may still find them used at horse and greyhound tracks.

Arbitrage Betting

Fractional odds are - shock-horror - displayed as a fractions, with the two numbers representing the two possible outcomes of an event e.g. Basic fractional odds are simple to understand at a glance, but can become more complex when bigger numbers are involved. Moneyline and decimal odds were created as more simpler alternatives, with many gamblers viewing fractional odds as being somewhat dated. Still, the traditionalists stand by fractional odds and it’s certainly worth understanding how they work. To calculate your potential profit with fractional odds, you multiply your stake by the top number and then divide it by the bottom number. Three of them are offering 2/1 (3.00) and the other is offering 9/4 (3.25).

Features to Scrutinize

To put this into practice, you really have to focus on sports that you know inside and out. All of the major betting brands across the world invest heavily in professionals who create and update their odds live and in real time. However, if you see a bit of news or get some inside info that you think could have an effect on the outcome of a sports game, then jump on a comparison site to check out the odds - you might’ve realised something before the bookies and therefore could find yourself a valuable little bet. Another way that you can give yourself a chance of finding the best odds and valuable bets is to follow tipster articles and social media accounts. Additionally, you can also join forums and communities of fellow bettors you shop around and share the bets and odds that they have found.

Why you need to compare sports betting odds

If we use a $100 stake at 2/1 odds as an example, you’d calculate it thus - ($100 x 2 = $100) ÷ 1 = $200. To calculate the percentage, you divide 100 by the total of the two numbers and then divide it by the bottom number - 100 ÷ 3 = 33.3% x 1 = 33.3%.

Using your knowledge to beat the bookies

There are multiple online sportsbooks around today that can easily be accessed and signed up to.

Well it should be no different with betting odds, and it’s never been easier to do so. Our comparison tool updates odds in real time from multiple bookies, meaning that you can find the best odds being offered on a certain line at any moment in time. Sometimes it is far from obvious that a bookmaker's early price is the best you are likely to be offered. The night before the race there are two bookmakers offering 2/1 (3.00). The Betfair exchange market is reaching a reasonably well-formed state (less than 110%) and is currently showing a Back price of 3.20.

If the Betfair exchange price drifts to say 3.50, then at least one of the bookmakers may go 9/4 (3.25) or a new bookmaker may come in at 9/4 (3.25) or even 5/2 (3.50).

How To Trade A Horse On A Betting Exchange

Never be tempted to bet at shorter prices than your minimum value point. Wherever possible, use Best Odds Guaranteed bookmakers. If you take an early price and the subsequent SP is bigger than the price you took, you will be paid at the bigger price. Best Odds Guaranteed bookmakers for each event are highlighted at Oddschecker. These are crucial in comparing the prices on offer. I would then take the 5/2 (3.50) straight away and probably the 9/4 (3.25) too, remembering that my lowest value point is 6/4 (2.50).

Final Thoughts

The main odds comparison sites are: Oddschecker, Easyodds, Betting.com. However, don't click through to place your bets directly from odds comparison sites. Bookmakers can monitor this behaviour and may penalise you if you consistently hit their top prices using this method, so open a new window to log into your chosen bookmaker's site. Once a Betfair exchange market is reasonably well-formed (ie the Book% is less than 110%), then the behaviour of bookmakers' prices can be confidently anticipated. Generally speaking, bookmakers' prices will mirror trends on the Betfair exchange.

If a Betfair exchange price starts to shorten, bookmakers' prices will follow suit and vice versa (or at least when a Betfair exchange price drifts, bookmakers' prices will either be held or lengthen, but they generally won't shorten). Betfair exchange trend graphs (Price/Volume over time) are useful for monitoring exchange price patterns and fluctuations. Knowing when to snap up an early price Sometimes you can be confident that a bookmaker's early price is unlikely to get any bigger and may, in fact, shorten fairly soon. Here's an example: You have decided to bet at 6/4 (2.50) or bigger. The Betfair exchange market is reaching a reasonably well-formed state (less than 110%) and is currently showing a Back price of 3.10. Often, it is better to wait than to immediately snap up the best current bookmaker price, especially if only two or three firms have opened their markets.

Works in Background

Odds of +200 is an example of moneyline odds, sometimes referred to as “American odds” as it is the most common odds format used in the USA. FInd out how they work right here at betting.net™. Plus and minus odds represent negative and positive number odds and are commonly used in sports betting in the US. Find out more in our sports betting guide here at betting.net™. We've tested and compared the top value betting software platforms available in 2025. Heavy support for a runner, particularly when it occurs over a short period of time during the early stages of a market, can result in its price being cut to an artificially low level. Once that burst of support has dried up, the price will begin to drift back out again as layers recognise that it has become too short. The very top price for any bet will almost always appear on the Betfair exchange, rather than with a bookmaker, but recognising when that peak has been reached is difficult and you can never know for sure when it has arrived.

You don't always need to stake your intended amount in one go. The trend graphs at the Betfair exchange (Price/Volume over time) are useful when you can't sit and watch price developments. The reason I prepare my bets very early (they are ready, at the latest, in the early evening for the following day's racing) is to give investors every chance of hitting the top prices.
