Sports betting isn’t just about picking winners—it’s about finding value. Even experienced bettors sometimes get caught up in betting on favorites or popular teams. But the key to long-term success lies in spotting value bets and making decisions that consistently deliver a return on investment (ROI).
If you’re looking to become a smarter bettor and stop relying on luck, this guide will walk you through what value bets are, how to find them, and how they can help you boost your profits over time.
What Is a Value Bet?
A value bet happens when the odds offered by a bookmaker are higher than the actual probability of the outcome. In other words, you’re betting on something that has a better chance of happening than the odds suggest.
For example, if a team has a 50% chance of winning, the fair odds would be 2.00 (in decimal format). But if a sportsbook offers 2.20 for that same outcome, there’s value in that bet. You’re getting more payout than the true risk should allow.
Spotting this edge is what separates profitable bettors from casual players.
Why Value Matters More Than Wins
Many beginners focus too much on how often they win. But even a high win rate doesn’t guarantee profit if you’re consistently betting on outcomes with poor value.
Let’s say you bet on a heavy favorite with odds of 1.20. Sure, you might win often, but you’ll need to win a lot just to break even. On the other hand, betting on slightly underrated teams at higher odds might offer better long-term value, even if you win less often.

Value is about the quality of your bets, not just the number of wins.
How to Calculate Value
You don’t need advanced math skills to spot value bets. Here’s a simple formula you can use:
Value = (Probability × Odds) – 1
If the result is greater than 0, it’s a value bet.
Let’s break it down:
- You estimate that Team A has a 60% chance of winning.
- The sportsbook offers odds of 2.10.
- Using the formula: (0.60 × 2.10) – 1 = 0.26
That means you have a 26% value margin on that bet. Over time, consistently betting on outcomes with positive value will help you turn a profit—even with some losses along the way.

How to Estimate True Probability
This is the tricky part. The sportsbooks, including some of the Best Maryland Sports Betting Sites, are very good at setting odds because they use advanced models and tons of data. But that doesn’t mean they’re always perfect.
Here are some ways to develop your own probability estimates:
Use Historical Data
Look at head-to-head records, team form, injuries, and performance in similar matchups. Historical trends often repeat, especially in team sports.
Follow Sharp Money
Sometimes you’ll notice odds shift significantly before a game. This is often a sign that professional or “sharp” bettors are placing big bets. Tracking these movements can give you clues about where the value lies.
Create Your Own Power Rankings
If you’re betting regularly on one sport, start building a simple rating system. Assign a number to each team based on their overall strength, and adjust it over time as results come in. You’ll start to develop a more accurate sense of how teams perform relative to each other.
Don’t Always Follow the Crowd
Bookmakers know that most bettors favor popular teams or emotional bets. They often adjust odds accordingly to balance their books. That means there may be less value in favorites and more in overlooked teams.
By staying objective and looking past the hype, you can spot situations where the public perception doesn’t match actual performance.
For example, a well-known football team might be overvalued because of recent media buzz—even if their form has been poor. Their opponent might offer much better value.
Shop Around for the Best Odds
Even a small difference in odds can affect your ROI over time. Always compare odds across multiple sportsbooks before placing a bet.
If one site offers 2.10 and another offers 2.25 on the same bet, taking the higher odds can significantly increase your profit margin in the long run.
Many seasoned bettors have accounts with several sportsbooks just for this reason.
Track Your Results and ROI
To know if your strategy is working, you need to track your bets. Record details like:
- The event and market
- Stake amount
- Odds taken
- Outcome (win/loss)
- Your estimated probability
This will help you calculate your ROI over time. ROI is your total profit divided by your total stake, expressed as a percentage. A positive ROI means your strategy is working.
Tracking also helps you spot patterns—like which leagues you do well in, or what types of bets are most profitable for you.
Final Thoughts
Value betting is not about chasing longshots or guessing outcomes—it’s a calculated approach to betting smarter. By learning to estimate true probabilities, compare them to bookmaker odds, and stay disciplined with your bankroll, you can improve your edge and boost your ROI.
You won’t win every bet—and you don’t have to. The goal is to consistently place bets that offer long-term value. That’s the secret professional bettors rely on, and now, so can you.
Stay sharp, stay objective, and always bet with your head, not just your heart.
