Parlay Payout Calculator
Calculate the payout on a parlay or accumulator bet.
About Parlay Payout Calculator
Parlay odds multiply, so returns grow quickly while the probability of winning collapses just as fast. Four legs at even money give sixteen to one odds but only a one in sixteen chance. The bookmaker margin compounds across legs too, which is why parlays carry a far worse expected value than the same bets placed singly.
Formula
Parlay Payout
Combined odds = the product of every leg’s decimal odds
- parlay
- A bet requiring every leg to win
- combined odds
- The product rather than the sum of the individual odds
