Parlay Calculator

How a parlay pays

A parlay ties several bets into one wager: every leg has to win or the whole ticket loses, and in exchange the odds multiply. Convert each leg to decimal odds, multiply them together, and that product times your stake is the payout. Because the prices multiply, a small edge on each leg compounds, and so does a small difference in price between books.

That last part is the whole game. Two sportsbooks can offer the same three legs and pay very different amounts on the parlay, because each leg's price gap stacks. Most parlay calculators stop at the arithmetic. Ours is step one of something better.

Find the book that pays the most

Enter your legs above for the math, then build the same parlay on the live Pick Card: The Odds Gap holds every book's price on every leg, so it prices your exact parlay across all of them and shows which sportsbook pays the most. That is the difference between doing the multiplication and actually getting paid the most for it. To size the bet, use the Kelly Calculator; to lock a profit on a live parlay's last leg, use the Hedging Calculator.
