🎯 What is a Parlay Bet?
A parlay is a type of sports bet that combines two or more individual wagers into a single bet. For the parlay to win, all individual bets (called “legs”) must win. While parlays are riskier, they offer significantly higher payouts because the odds multiply with each added leg.

💡 How the Calculator Works
The Vegas Parlay Calculator works using a simple algorithm that multiplies the odds for each leg of the bet. Here’s how:
- Convert American Odds to Decimal Odds:
- For positive odds (e.g.,
+150):decimal = (odds / 100) + 1
→(+150 / 100) + 1 = 2.5 - For negative odds (e.g.,
-110):decimal = (100 / abs(odds)) + 1
→(100 / 110) + 1 ≈ 1.91
- For positive odds (e.g.,
- Multiply All Decimal Odds Together:
The calculator multiplies all decimal values to get a total multiplier. - Calculate Payout:
Payout = Bet Amount * Total Multiplier - Calculate Profit:
Profit = Payout - Bet Amount
This ensures accurate, real-time results based on the exact odds you enter.
🧮 Example Parlay Calculation
Let’s say you bet $50 on the following three lines:
-110+150-200
Step-by-step Calculation:
-110→1.91+150→2.5-200→1.5
Total Multiplier = 1.91 × 2.5 × 1.5 = 7.1625
Total Payout = $50 × 7.1625 = $358.13
Profit = $358.13 – $50 = $308.13
