How to Use the Parlay Calculator Enter your wager amount and odds (yellow fields) for each leg of the parlay and you will see your potential profit, equivalent American and Decimal odds, as well as the implied win probability of your parlay bet. For a single bet, enter odds in American format. To win a parlay wager all individual legs must win. For example, if you have five teams in your parlay bet then all five individual bets must win. Even just one losing selection is enough for the parlay bet to lose, its a higher risk higher reward bet with the odds of each selection multiplying to combine for the total parlay odds. The reason why parlay bets are so popular is that for a relatively small outlay you can win a large amount of money. Parlay odds make it that you can get a lot more for your $10 than betting just on the Raiders to win. The risk is greater – but so is the potential payout. Conversely, if the bettor made a parlay with the exact same six games and won, then they are left with a win of only $4,000 (6-game win: +4000). Interestingly, these is a very slight edge using a three game parlay over the all-in method. A three game parlay pays out $600 on a $100 bet versus the all in method which would only pay $595.79.
