Welcome to the wonderful, risk-free, world of arbitrage.
Here’s how this application works:

1) Input your odds
2) Select the odds type
3) Hit the “Calculate” button
4) Assuming you have an opportunity, the calculator will tell you what percentage of your total wager to bet on each event. The arbitrage profit percentage is also displayed!
5) If you enter whole numbers in the “Wager Amount?” field, the calculator will automatically update you with how much you have to bet on each event to lock in your guaranteed profits.

A few notes.
Decimal takes decimals EG “3.5” and “.25”
Money Line takes positive and negative numbers EG “300” and “-150”
Fractional takes fractions containing the “/“ symbol EG “2/5” and “45/21”

The best arbitrage opportunities usually occur when odds makers first release the odds. Remember, this is free money because there is no risk. These opportunities usually don’t last long! Stay sharp and good luck!
