Combine up to 8 legs of American odds into a payout, profit, and implied probability. Every leg has to hit. See exactly what that costs your odds.
A parlay combines multiple bets into one wager that only pays if every leg wins. The payout grows fast because the odds multiply, but so does the chance of losing: two coin-flip legs at -110 each combine to only about a 27.4% chance of both hitting, even though either one alone is close to 50/50.
This calculator assumes every leg is independent, which is the standard convention for legs from different games. Legs from the SAME game are correlated and priced differently. See NoPunt’s same-game parlay tool for that math.
Before building a parlay, check the model’s read on each game individually: this week’s picks show a win probability for every matchup, and the Edge flags the plays the model actually disagrees with the market on.
