About Value Betting
The Value Betting Calculator helps you determine if a bet has positive expected value (EV) by comparing your estimated probability against the bookmaker's odds. Expected Value represents the average amount you can expect to win or lose per bet over the long term.
Why is EV Important?
- Profitable Betting: Positive EV bets are profitable in the long run
- Risk Assessment: Helps you avoid -EV bets that favor the bookmaker
- Bankroll Growth: Consistently betting positive EV leads to long-term profit
- Objective Analysis: Removes emotion from betting decisions
Mathematical Formula
EV = (P × (Odds - 1) × Stake) - ((1 - P) × Stake)
Where:
- P = Your estimated probability (as decimal)
- Odds = Decimal odds from bookmaker
- Stake = Your bet amount
Frequently Asked Questions
How do I find value bets?

What if I have positive EV but still lose?
Even positive EV bets can lose in the short term due to variance. What matters is the long-term average. If you consistently bet positive EV, you will be profitable over many bets.
