The Parlay Calculator helps determine how much money you'd win if you risked a certain amount of money on a parlay. In the tool, you can enter your bet amount and the odds for each leg.
You can find the Betting Calculators on the top bar of the home page or if you scroll down and check the right side of the home page.
In the example above, the bettor is risking $100 on a 2-leg parlay. Simply add the odds for each leg and click 'Add Bet'. Each of the two legs in this parlay are standard -110 juice. Per the calculator, this parlay would typically win $264.43, which would pay out $364.43 in total.
You can add as many legs to your parlay as you need. The 9-leg parlay in the example below would need nearly $100,000 if it won.
