Legs multiply as if they're independent. A same-game parlay's legs move together, so books price it lower.
How to use the parlay calculator
Parlay odds multiply the decimal prices of every leg. The payout grows quickly, but the ticket loses when any required leg fails.
- 1Add each parlay leg and enter its odds.
- 2Enter your total stake.
- 3Review combined odds, implied probability, profit, and payout.
Formula and assumptions
Combined decimal odds = decimal odds leg 1 × leg 2 × every additional leg.
The result assumes every leg is accepted and independent. Sportsbooks may adjust correlated parlays or restrict certain combinations.
Questions
Answers about this free parlay calculator, sports betting odds, payouts, and the math behind each result.
- Convert each leg to decimal odds, multiply the decimal values, then convert the result back to your preferred format.
- Related outcomes are not independent, so multiplying their standalone prices can overstate or understate the true combined probability.
