A value bet is a bet where the odds offered by the bookmaker are higher than the actual probability of the event occurring. In other words, it’s an opportunity where the bookmaker underestimates the chances of a result happening, thus offering positive value to the bettor.
Mastering the value bet concept is essential to becoming profitable in the long term in sports betting. Understanding how to read odds and probability is the first step to identifying value. Master ROI and yield measurements to track your success.
How to identify a value bet?

The mathematical formula
To determine if a bet has value, use this formula:
Value = (Odds × Estimated probability) – 1
- If the result is positive: it’s a value bet
- If the result is negative: no value

Concrete example of calculation
Match: PSG vs Marseille
- Odds for Marseille victory: 4.50
- Your estimate: Marseille has 30% chance of winning
Calculation: (4.50 × 0.30) – 1 = 1.35 – 1 = +0.35
Positive result = value bet! The value is 35%.
💡 Find Value Bets Automatically
Why do value bets exist?
1. Bookmaker evaluation errors
Even the best bookmakers can misjudge certain matches:
- Lack of information about a team
- Last-minute injuries not taken into account
- Recent form poorly analyzed
- Media bias influencing odds
Learn how AI is changing value detection and explore xG analytics for football value.
2. Balancing stakes
Bookmakers sometimes adjust their odds to balance bettors’ stakes, inadvertently creating value bets:
- Inflated odds on popular underdogs
- Favorites overpriced out of caution
- Late adjustments creating opportunities
Understand how different bookmakers price and why accounts get limited for winning.
3. Less liquid markets
Value bets appear more often on:
- Minor leagues
- Less popular sports
- Special markets (corners, cards…)
- Long-term bets
Explore value in cricket/IPL markets, African football, or Brazilian leagues.
Strategies to find value bets
1. Develop your expertise
Specialize in:
- 1-2 leagues maximum for in-depth knowledge
- Specific markets (under 2.5 goals, BTTS…)
- Specific periods (end of season, cup matches…)
Follow our 90-day training program to develop expertise. Master all bet types for more opportunities.
2. Use advanced statistics
Essential data to identify value:
- Expected Goals (xG) and xG Against
- Possession and shots on target
- Head-to-head history
- Form over the last 5-10 matches
- Home/away statistics
3. Compare odds
A value bet at one bookmaker may not be elsewhere:
- Use odds comparison sites
- Open multiple bookmaker accounts
- Monitor odds movements
- Take advantage of boosted odds
Use our Talacote platform for real-time comparisons. Find the best bookmakers for value betting.
4. Optimal timing
The timing of placing your value bet is crucial:
- Opening odds: often the best values
- 2-3 hours before the match: team information available
- Live betting: react to match events
Master live betting strategies and learn optimal cash out timing.
Bankroll management for value bets
The Kelly method
The Kelly formula calculates the optimal stake for a value bet:
Stake = (Probability × Odds – 1) / (Odds – 1) × Bankroll
Learn the complete Kelly Criterion guide for professional staking.
Practical example
- Bankroll: €1000
- Odds: 3.00
- Estimated probability: 40%
Kelly calculation: ((0.40 × 3.00) – 1) / (3.00 – 1) = 0.10
Recommended stake: 10% of bankroll = €100
Conservative adjustments
Full Kelly is often too aggressive. Use:
- Kelly ÷ 4 to start (€25 stake in the example)
- Kelly ÷ 2 when you’re comfortable
- Fixed stake of 2-3% if in doubt
Master complete bankroll management and prepare for variance and bad runs.
Pitfalls to avoid
1. Overestimating your abilities
Finding true value bets requires:
- Objective analysis
- Reliable data
- Extensive experience
- Constant self-reflection
Avoid common beginner mistakes and understand all betting terminology.
2. Confusing value with high odds
❌ Common mistake: “The odds are 5.00, it must be value!”
✅ Reality: A favorite at 1.50 can offer more value than an underdog at 10.00
Explore value in Asian handicap markets or accumulator strategies.
3. Neglecting variance
Even with value bets:
- Losing streaks are normal
- Minimum 100-200 bets to judge
- Patience is essential
- Short-term can be misleading
4. Betting on everything
A true value bet is rare:
- Maximum 5-10% of analyzed matches
- Quality > Quantity
- Better to wait than force
