About the Parlay Calculator
A two-leg parlay at -110 a leg pays $364.46 on a $100 wager: $264.46 profit at combined odds of +264, or 3.64 in decimal. The parlay calculator turns each leg’s American odds into decimal odds and multiplies them, and every leg must win: one losing leg loses the whole bet. Its implied probability, 27.44% here, carries each leg’s bookmaker margin and is not the chance of winning.

Frequently asked questions
- How are parlay odds calculated?
- Convert each leg to decimal odds (+150 is 2.50, -110 is 1.91) and multiply them. The payout is the wager × the combined decimal odds and the profit is the payout minus the wager. A -110 leg and a +150 leg combine to 4.77, or +377, so $100 returns $477.27.
- How much does a 3-leg parlay pay?
- With every leg at -110, $695.79 on a $100 wager, odds of +596. With legs of +150, -200 and +120 the decimal odds 2.50 × 1.50 × 2.20 make 8.25, so a $10 wager returns $82.50 at +725.
- What happens if one leg of a parlay pushes?
- The calculator does not model it, because sportsbooks set their own rules for a leg that pushes or is voided. If yours removes the leg, delete it here to see the payout on the legs that are left.
- How many legs can a parlay have here?
- From 1 to 20. Odds that combine to more than 1,000,000,000,000 in decimal are not shown, and long shots reach that cap well before 20 legs: 11 legs at +1000 still show a payout, 12 give a message instead.
- Is the implied probability of a parlay the chance it wins?
- No. It is 100 ÷ the combined decimal odds, so it includes the bookmaker’s margin on every leg, and it treats the legs as independent of each other. Two -110 legs imply 27.44%.
- Can I enter decimal or fractional odds?
- Yes. The odds format menu takes American, decimal, fractional or implied probability, and each leg also shows its price in the other three: -110 is 1.91 decimal, 10/11 fractional and 52.38% implied. A rounded decimal is a slightly different price: 2.50 and 1.91 combine to 4.775 ($477.50 on $100), while 3/2 and 10/11 combine to 4.77 ($477.27).
