What does my parlay pay, and how often must it hit?

Multiply up to 12 legs to get the parlay odds, the payout on your stake and the win chance needed to break even.

How it works

• Parlay decimal odds = the product of every leg’s decimal odds. Every leg must win.
• Break-even chance = 1 / parlay decimal odds.
• The book’s margin compounds: two -110 legs pay +264, while the fair price of two coin flips is +300.

Questions

Why do parlays favour the book?

Each leg carries the margin, and the margins multiply. A two-leg parlay of -110 legs holds about 9%, double a single bet.

Are same-game parlays priced the same way?

No. Books adjust for correlated legs, so a same-game parlay usually pays less than this product.
