Parlay Math Explained

Parlay odds compound multiplicatively. Convert each leg to decimal odds, multiply them together, and you get the combined decimal odds for the parlay. The math:

Parlay decimal = Leg₁ decimal × Leg₂ decimal × ... × Legₙ decimal

For example, three -110 legs (each 1.91 decimal) combine to 1.91 × 1.91 × 1.91 = 6.96 decimal, or roughly +596 American. A $25 wager wins $149 profit if all three legs cash.

Every additional leg multiplies the payout, but a single losing leg busts the entire ticket. Parlay juice is the highest-margin product for sportsbooks — read our parlay guide for strategy.
