How it works

Each leg is turned into decimal odds, the decimals are multiplied together, and the result is multiplied by your stake. The payout includes your stake; the to-win figure is the payout minus the stake.

Decimal from American: +150 → 1 + 150/100 = 2.50. -110 → 1 + 100/110 = 1.909
Parlay decimal = leg 1 × leg 2 × … × leg n
Payout = stake × parlay decimal. Implied probability = 1 ÷ parlay decimal

Example: two legs at -110 is 1.909 × 1.909 = 3.645, which is +264 in American odds. A $100 stake pays $364.46 back, $264.46 of it winnings.

Pushes: most sportsbooks remove a pushed leg and pay the parlay at the odds of the legs that are left. Tap Push on a leg to see that price. If every leg pushes, the stake comes back.

Questions

How is a parlay payout calculated?

Convert each leg to decimal odds, multiply them together, then multiply by your stake. That is the total payout, stake included. Subtract the stake to get the amount you would win.

What does a 2-leg parlay at -110 pay?

+264. Each -110 leg is 1.909 in decimal odds, and 1.909 × 1.909 = 3.645. A $100 bet returns $364.46 in total if both legs win.

What happens to a parlay when one leg pushes?

At most sportsbooks the pushed leg is removed and the parlay is paid at the odds of the remaining legs, so a 3-leg parlay with one push pays like a 2-leg parlay. Rules vary by book, so check your sportsbook's house rules.

Is the implied probability the real chance the parlay hits?

Not exactly. It is the chance the price implies, and each leg's price includes the sportsbook's margin, so the fair chance is usually a little lower than the implied probability shown.
