Parlay Odds Calculator
Stack NBA, NFL, NHL and MLB legs in American, decimal or fractional odds and see the payout and the real chance of hitting it.
Using the parlay odds calculator
Enter your wager and the price of each leg. Moneylines like -150 or +130, decimal odds and fractional odds all work in the same box.
Add a leg for every game in the ticket and remove one with the cross. The parlay price and payout update as you type.
The implied probability line is the one to watch: it is the chance the odds give for every leg landing together, and it drops fast as legs are added.
Example: A $25 three-leg NBA parlay at -140, +110 and -115 pays $168.26: the combined price is about +573. The odds imply a hit roughly one time in seven.
Questions people ask
How is a parlay payout worked out?
Each leg is turned into decimal odds, the decimals are multiplied together, and the result is multiplied by the wager.
What if one game is a push?
Most books drop the pushed leg and pay the parlay on what is left. Delete that leg here to see the new payout.
Are same-game parlays priced the same way?
No. Legs in the same game are linked, so books price them with their own correlation model. This calculator is for legs from separate games.
Does adding a heavy favourite help?
It adds little to the payout but still has to win. A -400 leg only raises the price by 25% while adding a real chance of losing.
