Parlay calculator
Enter the odds for each leg in American (-110, +150) or decimal (1.91) format. Leave a leg empty to skip it.
How it works
A parlay pays only if every leg wins. The combined decimal odds are all the legs multiplied together, and the payout is the stake times that number.
Example: three legs at 1.91, 2.20 and 1.80 give combined odds of 7.56. A 20 bet returns 151.27, which is 131.27 profit.
Each leg carries the sportsbook margin, so the margin compounds as you add legs. Parlays pay more, but the house keeps a bigger share on average.
Frequently asked questions
How is a parlay payout calculated?
Convert each leg to decimal odds, multiply them together, then multiply by your stake. The result includes your stake.
What happens if a leg is void or pushes?
At most sportsbooks the leg is removed and the parlay is paid at the odds of the remaining legs. Check the house rules, since some books grade it differently.
Are same game parlays calculated the same way?
No. Legs in a same game parlay are related, so sportsbooks price them with their own model. The quoted price is usually lower than multiplying the legs.
