FAQ
How do I calculate a parlay payout?
Turn each leg into decimal odds, multiply them, then multiply by your stake. $50 on a two-leg parlay at -110 and -110 is 1.909 × 1.909 = 3.64, so it pays $182.23, a $132.23 profit.
How are parlay odds calculated?
Multiply the decimal odds of every leg. Three legs at 1.91 give 1.91 × 1.91 × 1.91 ≈ 6.97, so $100 returns about $697.
Why are parlays worse value than the same bets placed separately?
Every leg carries vig, and multiplying legs compounds it. More legs, more vig.
What about correlated legs?
The math assumes legs are independent. Legs that move together win together more often, which is why books block or reprice them.
How do I know if a parlay price is fair?
Enter no-vig odds for each leg to get the fair parlay odds, then compare them with the book's payout. The gap is the vig you pay.
