What is an arbitrage calculator?

The arbitrage calculator on our page simply reveals how much you have to wager to successfully make an arbitrage bet.
You just have to type in your original stake, the odds for the two or three outcomes of the same sporting event, and then the calculator will reveal how much you need to wager for the other bet/s. You will also get to see your returns once the sporting event has concluded and you have won your bet. Here are the sports that you can use our arbitrage calculator for:

Arbitrage calculate usageSports
Two-way arbitrage betsFootball, basketball, hockey, baseball and so on
Three-way arbitrage betsSports such as soccer that also feature a draw
Cannot be usedMany racing sports with multiple competitors such as NASCAR racing and horse racing

What does arbitrage betting mean?

Arbitrage betting means that you bet on all of the possible outcomes for a sporting event and vary your stakes accordingly so as to ensure that you get a return - regardless of what happens in the game.

An example could be if you wanted to bet on an NBA game between Cleveland Cavaliers and Boston Celtics. Here you would bet on both the Cavaliers and the Celtics to win. Obviously the odds for both teams would be different, and this means that you would have to adjust your stakes accordingly.

Just remember that most sportsbooks take a fairly dim view of arbitrage betting as they see it as being unfair. As a result, you will need to make your opposing bets at different sportsbooks to avoid your account getting temporarily suspended.

  • Bet on opposing outcomes in the same game
  • Lock in a profit regardless of what happens
  • Not welcomed at sportsbooks

How does the arbitrage betting calculator work? A step-by-step guide

The FAQ at the bottom of this page contains the formula that details how arbitrage bets are worked out, but if you want a quicker way to get into the action, follow this step by step guide to using our arbitrage calculator:

  1. Pick your preferred odds format.
  2. Select whether your sporting event is a two-way or three-way market.
  3. Enter the odds from your original bet.
  4. Type in the stake that you are planning to wager on this bet.
  5. Enter the odds from the opposing bet/s.
  6. Now the arbitrage calculator will reveal how much you need to wager on the opposing bet to lock in a winning result. Plus you will also get to see your total profit and payout.

    Examples of using our arbitrage calculator

    So let’s take a closer look at some examples of how you might want to use our arbitrage calculator.

    Try two-way arbitrage betting on our calculator

    Here’s an example of using our calculator for a two-way arbitrage on one of the weekend’s NFL games. So for this, you picked a game between the Baltimore Ravens and New York Giants. You went to the ESPN betting site and found the Ravens’ odds for a win were -150 and you wanted to wager $10. From here you could fire up our arbitrage calculator and do the following:

    1. Pick American odds as the odds format.
    2. Select a two-way betting market.
    3. Enter the Ravens’ moneyline odds of -150.
    4. Type in your betting stake as $10.
    5. Go to another sportsbook and find that the Giants’ odds to win are +300.
    6. Type in the Giants odds.
    7. Now the arbitrage calculator will automatically reveal that you would need to wager $4.17 on these Giants odds in order to ensure that you don’t lose anything regardless of what happened in the game. Plus you would also get a total payout of $16.67 from your total stake of $14.17 to reveal that you had made a $2.50 profit.

      Calculate a three-way arbitrage bet

      Of course, there’s every chance that you might want to try an arbitrage bet on a sport like soccer that features three potential outcomes - a win, a loss and a draw. Just note that it can be harder to find an arbitrage bet that works with three markets, but it is possible and our betting calculator will help you do it.

      Handy tips for using our arbitrage calculator

      Arbitrage betting is something that may take a little bit of skill and experience to get right. So here are some simple tips to keep in mind:

      🔍 Know Which Sportsbooks to Use

      🏆 Stick to the Larger Sporting Events

After all, you might not find too many sportsbooks with the correct odds for that amateur table tennis tournament on the other side of the world.

      ⏹️ Know When to Stop

      It’s worth remembering that arbitrage betting isn’t something that most sportsbooks will tolerate and this means that you should be careful when using this bet strategy.
