How the Calculator Works
Our value betting calculator uses three key inputs to determine if a bet offers value:
Key Calculations
1. Implied Probability
Implied Probability = (1 / Decimal Odds) × 100This shows what probability the bookmaker's odds represent
2. Expected Value (EV)
EV = (True Probability × Decimal Odds) - 1This indicates your theoretical edge on the bet
3. Expected Return
Expected Return = Stake × EVThis shows your theoretical profit in currency terms
Important Note
The accuracy of the calculator depends on your ability to estimate true probabilities correctly. Always combine this tool with thorough research and analysis.
Frequently Asked Questions
How do I use the value betting calculator?
Enter the bookmaker's decimal odds, your estimated true probability of the outcome, and your planned stake. The calculator will show you the implied probability, expected value (EV), and potential returns.
What is a good expected value (EV) percentage?
Generally, any positive EV indicates a potentially profitable bet. Professional bettors typically look for EVs of +2% or higher, though the specific threshold depends on your betting strategy and risk tolerance.
How accurate is the calculator?
The calculator's mathematical formulas are 100% accurate, but the results depend on the accuracy of your probability estimates. Success requires combining the calculator with good research and analysis.
Should I bet whenever there's positive EV?
While positive EV suggests a profitable opportunity, you should also consider other factors like your bankroll management strategy, the size of your edge, and your confidence in your probability estimate.
