How Parlay Odds Work
A parlay combines multiple bets into one wager. All legs must win for the parlay to pay out. The combined odds are calculated by multiplying all individual leg odds together.
While parlays offer higher payouts, the implied probability of winning decreases with each added leg. Use this calculator to evaluate whether the potential reward justifies the risk.
Frequently Asked Questions
How are parlay odds calculated?
Multiply the decimal odds of every leg together. Four legs at 2.00 each give 2 times 2 times 2 times 2 = 16.00, so a $10 parlay returns $160.
Why are parlays harder to win?
Every leg must win. Combining bets multiplies the payout but also multiplies the risk, so the chance of winning all legs falls quickly as you add more.
What is a same-game parlay?
A standard parlay combines legs from different events; a same-game parlay combines correlated legs within one event, which books price differently to account for that correlation.
Do parlays have worse expected value?
Because the book margin compounds across every leg, parlays usually carry a higher total hold than the same bets placed singly. That is the trade-off for the larger potential payout.
