Parlay Payout Calculator
Enter the American odds for each leg of your parlay and a stake. The calculator combines them into total parlay odds, your potential payout, and the implied probability of hitting all legs.
Parlay legs
Potential payout: —
Implied probability: —
Parlay odds are the product of each leg's decimal odds. The catch: the implied probability of hitting all legs is the product of each leg's probability — so a 3-leg parlay of -110 bets has roughly a 1-in-8 chance, not the "big payout" the headline suggests. This tool shows you the real number.
