The arbitrage calculator gives you betting strategies for series of bets where the odds have slipped in the bettors favor. Arbitrage in sports betting is a series of bets where the sportsbooks edge is below zero meaning that regardless of outcome, the bettor can break even or make a profit at no risk. Arbitrage opportunities don’t happen every day so be sure to calculate out your best outcome and make sure you aren’t going to be the one losing when you don’t have to.

Usually, you find arbitrage opportunities by maintaining betting accounts at multiple sportsbooks and as the odds shift you get odds on one site that haven’t moved quickly enough. You place a bet on both sides but across two sites to guarantee profit. Sometimes, as in futures betting, you spread the risk across a number picks and sportsbooks.

The arbitrage calculator is going to give you a couple of pieces of information. First of all, you are going to need to enter the american odds offered for a single betting event. You will need at least two but ca enter a number of outcomes (i.e. team 1 win, team 2 win, tie). Also you are going to have to choose a favorite. This is the pick that you would bet on if you had to choose one.

Once you have entered your odds and favorite hit calculate and get some important information: the fact that an arbitration opportunity exists. If your edge over the sportsbook isn’t in the positive numbers, then no amount of calculating is going to give you a sure thin. Providing the arbitrage calculator tells that you you have an opportunity, the chart below will show you your options. Mostly for illustration the first column just shows you the outcome if you placed your bet your favorite. The second column gives you the options if you spread the risk between each of the betting options. This gives you the best chance for an outcome from each of the outcomes. The final column shows the best outcome if your favorite is right, but limits you to break-even if the other options occur.
