Parlay Calculator
Add each leg in American odds to see the true combined price, your payout on any stake, and — the part the apps bury — the actual probability the whole ticket cashes.
How parlay payouts work
A parlay (or accumulator) combines multiple bets into one ticket. Every leg has to win, and in exchange the odds multiply. To find the price, each leg's American odds are converted to decimal odds, all the decimals are multiplied together, and that combined number times your stake is the total payout.
The catch most bettors miss
Because every leg is independent, the chance the whole parlay hits is the legs' probabilities multiplied— which collapses quickly. That's why parlays feel lucrative but drain bankrolls: the payout rarely keeps pace with how steeply the odds of winning drop. This calculator surfaces that combined win probability so you can judge whether the payout is actually worth the risk.
