Parlays are a popular choice among sports bettors, often seen as an exciting way to increase potential payouts. However, many bettors don’t fully understand how parlays work or the mathematics behind them. This blog will break down the components of a parlay, explore the concept of expected value, and provide insights on how to use this knowledge to your advantage when betting.
What is a Parlay?
A parlay is a type of sports bet where multiple individual bets are combined into a single bet. The allure of parlays lies in the potential for a high payout from a relatively small wager. The catch? All individual bets in the parlay must win for the parlay to pay out. If any single bet loses, the entire parlay is lost.

For instance, consider a three-team parlay involving:
- The Bears -2
- Packers and Cardinals Over 48
- Browns -8 against the Eagles
In this example, each of these bets carries a negative expected value (EV), which means that they are not favorable to the bettor. Understanding this is crucial because sports books profit significantly from these types of bets.
The Math Behind Expected Value
Expected value is a key concept in sports betting that helps you understand the potential profitability of a bet. Sports books set odds that are not quite at the true odds, which means that the average bettor is likely to lose money over time. When you combine multiple negative EV bets into a parlay, you compound your expected losses.

For example, if each of the three individual bets has a negative EV of around 4-5%, when combined in a parlay, the expected loss increases. Instead of just losing 4% on each bet, the losses compound, leading to a much greater risk of losing your stake. In this scenario, you might expect to lose $1.33 for every dollar wagered, resulting in a significant disadvantage.
Positive Expected Value Parlays
Now, let’s discuss how to identify and leverage positive expected value parlays. A positive EV parlay consists of bets that have a greater likelihood of winning than what the odds suggest. By combining these favorable bets, you can enhance your overall expected return.

For instance, consider a new three-leg parlay with the following bets:
- Washington Commanders and Baltimore Ravens first quarter total points over 9
- Pittsburgh Steelers and Las Vegas Raiders total points over 39
- Los Angeles Chargers first half points under 9
These bets have been calculated to have a positive EV, meaning that the odds you receive are better than the actual probabilities of those outcomes occurring. When you combine these positive EV bets, they can compound positively, leading to a favorable expected return for the bettor.
Calculating Your Bets
To maximize your betting strategy, understanding how to calculate your bets based on expected value is essential. Tools like 8rain Station offer powerful analytics to help you assess your bets accurately. For instance, if you have a bankroll of $25,000 and a 20% Kelly multiplier, you can determine your stake based on the expected value of your bets.

Using the Kelly Criterion allows you to find the optimal bet size based on your edge and the likelihood of winning. This method helps you avoid betting too much or too little on any given parlay, keeping your bankroll management in check.
The Importance of Data in Betting
In the realm of sports betting, data is your friend. Sports books leverage data to set lines and odds in their favor, making it crucial for bettors to do the same. By understanding the math behind parlays and expected value, you can shift the odds back in your favor.

Parlay Strategies to Consider
When betting parlays, consider the following strategies to improve your chances of success:
- Focus on Positive EV Bets: Always prioritize bets with a positive expected value. This will help mitigate losses and maximize potential returns.
- Limit Your Parlay Size: While it might be tempting to create large parlays, limiting the number of legs can reduce risk. Three to four bets is often a sweet spot.
- Use Bet Sizing Techniques: Implement techniques like the Kelly Criterion to determine the optimal stake for your parlays based on your bankroll and edge.
- Stay Informed: Keep up with the latest sports news and trends. Injuries, weather conditions, and team dynamics can all impact the outcomes of your bets.
Conclusion
Parlays can be an exciting way to enhance your sports betting experience, but they require a solid understanding of the underlying mathematics and expected value. By focusing on positive EV bets, using proper bet sizing, and leveraging data analytics, you can improve your betting strategy and enjoy a more favorable outcome.
As you embark on your betting journey, remember to stay disciplined and approach your bets with a strategic mindset. The world of sports betting is vast, but with the right tools and knowledge, you can turn it into a rewarding endeavor.
