Top 5 Odds Comparison Sites

Upon finding differences in odds between bookmakers for the same sporting event, you can calculate how much you would need to place on the two bets to split your desired stake and remove the possibility of loss. Essentially, you divide your entire stake between the two outcomes, with a higher amount going on the side with lower odds.

When you see prices such as 9/2, 6/5 or 2/7 it can take a bit longer to understand your returns compared to odds that are 'to one' (e.g., x/1). With a £10 stake in a successful bet at a price of 9/2 the returns would be £55, a £45 profit plus the £10 stake back. A 9/2 price in decimals is 5.50 and in moneyline it’s +450. 6/5 is a slightly bigger price than even money (1/1) and is expressed as 2.20 in decimal format or +120 in American format. If you placed a £10 bet on a 6/5 selection you would get a return of £22 (£12 profit) on a winning bet.

2/7 is an odds against price, meaning there is quite a high probability of winning according to the bookmaker and if ti wins you are going to make a much smaller profit. A successful £10 bet at 2/7 returns £2.86 on top of the stake, so total returns of £12.86. This a 1.286 decimal odds price or -350 in American format. The most popular format outside the UK and Ireland, prices in decimals tell you what you stand to win if your bet is a successful one, including the stake being returned to you. Sometimes decimal prices are quoted to three decimal places, so if you place a £10 stake at 4.755 your total return on a correct bet is exactly £47.55, meaning you made a £37.55 profit. This, in turn, balances out both ends of the bet and means no matter which outcome wins, you make the same profit margin.

Arbitrage betting lets you place bets on all possible outcomes of a sporting event by exploiting discrepancies in odds between different bookmakers, ensuring you make a profit regardless of the result. It's similar to matched betting but doesn't rely on free bets, and while profits are usually small—often less than 1.2%—the method can be applied successfully in sports with clear outcomes, like NFL and Tennis. Arbitrage betting is a form of sports betting that has become extremely popular with the rise of sports betting markets. With the technique being focused on covering different outcomes, it is typically known as a form of matched betting, making it one of the many techniques that you can include in your betting strategy. If we look at this in a different example, it is similar to the idea of buying a product at a low, discounted price to then sell it for a higher price. By placing arbitrage bets, we find odds that are too high and too low compared to each other, meaning that when the sporting event ends, we will make at least some profit, regardless of the result. Sometimes dubbed ‘sure bets’, 98% of arbitrage bets return less than 1.2%. This means that when participating in arb betting, the strategy may require larger stakes or a lot of smaller bets that add up quickly to be worthwhile.

How Does Arbitrage Sports Betting Work?

So for a -400 price it would be 100 ÷ 400 + 1 = 1.25. For conversion of fractional odds to decimal take the first figure and divide it by the second figure then add 1.00. So 1/2 becomes (1 ÷ 2) + 1.00 = 1.50. Or 2/1 becomes (2 ÷ 1) + 1.00 = 3.00. The concept of implied probability is worth keeping in mind when you try to assess the value of odds from a bookmaker.

Available Payment Methods

The odds are set based on the implied probability of the outcome, such as a horse winning a race, or a football player scoring a goal. A 9/1 (10.00 or bet sports betting sites uk +900) bet is ‘expected’ to be successful once in every 10 occasions, so the probability would be 10%. A 1/4 (1.25 or -400) bet would be expected to be successful in four of every five attempts, it is heavily ‘odds on’ and the implied probability is 80%. You can make these types of calculation to assess the % chance you think your selection has of achieving the result you are betting on and see if you feel the odds are giving you enough value to make the bet.

Sports like the NFL and Tennis are much easier to place arbitrage bets on, as matches cannot end in a draw, so there are only 2 options. Arbitrage can still be used for football betting, but the risk is higher due to the chance of a game ending in a draw. Here is a step-by-step guide on how to find these bets through the tools at OddsMonkey: Using an odds comparison tool like OddsMonkey’s OddsMatcher, find a sporting event that offers two outcomes Find the highest odds available for each outcome from two different bookmakers Calculate whether the odds represent an arbitrage betting opportunity If so, calculate the individual stakes using our arbitrage betting calculator Place the bets at the respective bookmakers For example, we will use a tennis example, which could be Carlos Alcaraz up against Jannik Sinner, and there will be plenty of betting markets available across various bookmakers that can be used for arbitrage betting.

With a -500 price (1.20 decimal or 1/5 fractional) your successful bet with a £100 stake gives you a £20 profit, so £120 total returns. Also, to note, sometimes you will hear prices or odds in North America referred to as ‘lines’. Punters usually only find themselves in situations where they are trying to convert odds between formats, for example whilst on holiday or traveling and betting outside their home countries. It is useful to be able to do, if you don’t have a conversion table or tool to hand. Converting decimal odds to fractional, take the decimal and subtract 1.00, so 5.00 – 1.00 = 4/1.

However, if the decmial odds do not end in .00 then you will have to multiply the fraction to reach a non-decimal one. For example, 4.50 - 1.00 = 3.5/1, multiplied out to be 7/2 which is a normal odds presentation. For converting moneyline to decimal, when the moneyline price is positive divide it by 100 and add 1. Or for example, 5000 ÷ 100 + 1 = 51.00. When the moneyline price is negative, take 100 and divide it by the moneyline amount (first removing the minus sign), and add 1. As you can see in this example, both players have incredibly similar odds.

Although it takes a while to adjust from thinking in fractional odds to decimals they are becoming increasingly popular as they are easy to understand and accurately convey to the punter the exact return they stand to walk away with if their selection comes in. Decimal odds are also frequently used on betting exchanges. Follow the patterns of typical decimals odds such as 4.00 (3/1 or +300), 4.50 (7/2 or +350), 5.00 (4/1 or +400), 5.50 (9/2 or +450) and 6.00 (5/1 or +500) and you soon get a feel for how they translate into fractional or moneyline prices. When using decimal odds, you simply multiply your stake by the decimal odds and you will know exactly the return of a winning bet. As you might guess from the name this format is most popular in North America.

Again, if the moneyline figure is positive it tells you what you can win on a successful bet with a £100 stake. Remember though, -100 is evens, so your returns are exactly double what you put down. A £100 bet at a price of -100 returns £200, or £100 profit. With any negative moneyline figure beyond -100 the price is odds against and you stand to make less profit than the stake amount. With -105 moneyline (decimal 1.952 / fractional 20/21) odds your successful bet with a £100 stake win you £95.20 and so you walk away with £195.20 returns. However, this strategy involves placing bets on both players to win, ensuring a profit regardless of the match outcome.

Here is a step-by-step look at how this could be used as an arbitrage bet: Step 1: With an example total stake of £500, bettors would have to place approximately £235 on Carlos Alcaraz at the first bookmaker. Step 2: Place the remaining £265 on Jannik Sinner at the second bookmaker.

Step 3: If Carlos Alcaraz wins, the bettor will be awarded approximately £517 with a profit of £17, whilst if Jannik Sinner wins, the total return will be £609.50, with a profit of £109.50.

With this example, using a high stake might seem like quite an intimidating bet to place; however, if done correctly, then there are no risks and no matter how much you have placed, there will always be some form of profit coming back to you.
