Calculate parlay odds, payout, profit, and implied win probability for any 2+ leg sports bet. Enter American, decimal, or fractional odds and a wager amount.
Use these public guides to compare projections, player props, and sportsbook prices before combining legs.
Start by converting each leg to decimal odds. Once every leg is in decimal format, multiply the decimal odds together to get the combined parlay price.
Your total payout equals the wager multiplied by the combined decimal odds. Profit is the payout minus your original stake, which is why the calculator shows both payout and profit.
Each added leg lowers the hit rate and can compound sportsbook margin. Treat the result as a pricing check for a multi-leg bet, not as betting advice or a guarantee that a parlay has value.
