Step-by-Step Example

Let's calculate a 3-leg parlay:

• Leg 1: Team A to win at 2.00 (decimal odds)
• Leg 2: Team B to win at 1.50 (decimal odds)
• Leg 3: Team C to win at 3.00 (decimal odds)
• Stake: $100

Calculation: 2.00 × 1.50 × 3.00 = 9.00 combined odds Payout: $100 × 9.00 = $900 Profit: $900 - $100 = $800

Examples

Example 1: Simple 2-Leg Parlay

• Stake: $50
• Leg 1: -110 (American odds)
• Leg 2: +150 (American odds)
• Combined Odds: Approximately 3.59
• Potential Payout: $179.50

Example 2: 4-Leg Accumulator

• Stake: $25
• Leg 1: 1.80 (decimal)
• Leg 2: 2.20 (decimal)
• Leg 3: 1.65 (decimal)
• Leg 4: 2.50 (decimal)
• Combined Odds: 16.34
• Potential Payout: $408.50

Tips & Best Practices

Parlay Strategy Tips

1. Start Small: Begin with 2-3 leg parlays to understand the mechanics
2. Research Thoroughly: Each leg must win, so research all selections carefully
3. Consider Correlation: Avoid legs that are negatively correlated
4. Bankroll Management: Only bet what you can afford to lose

Common Mistakes to Avoid

• Too Many Legs: More legs = lower probability of winning
• Chasing Losses: Don't increase stakes to recover losses
• Ignoring Value: Ensure each individual bet offers value
• Emotional Betting: Stick to your research and strategy

When to Use Parlays

Parlays work best when:

• You have strong confidence in multiple selections
• You want to maximize potential returns on a small stake
• You're betting for entertainment rather than consistent profit
• You understand and accept the increased risk

Understanding Parlay Odds

How Parlay Odds Work

Parlay odds are calculated by multiplying the decimal odds of each leg: Combined Odds = Leg 1 × Leg 2 × Leg 3 × ... × Leg N

Probability Calculation

The implied probability of a parlay is: Parlay Probability = Leg 1 Probability × Leg 2 Probability × ... × Leg N Probability

House Edge Considerations

Remember that sportsbooks typically have a built-in edge on each individual bet, which compounds in parlays. This means the true odds are usually slightly lower than the calculated odds.

Conclusion

Parlay betting can be an exciting way to potentially win large payouts from small stakes, but it comes with increased risk. Use our calculator to understand the potential returns and probabilities before placing your bets. Remember to bet responsibly and never wager more than you can afford to lose.
