Expected Value Calculator

What is Expected Value (EV)?

Expected Value (EV) is a mathematical concept that helps bettors determine the potential value of a bet over the long run. It represents the average amount you can expect to win (or lose) per bet if you were to place the same bet many times with the same odds and win probability.

A positive EV indicates that a bet is profitable over the long term, while a negative EV suggests you should avoid the bet. Professional bettors use EV calculations to identify valuable betting opportunities and make more informed decisions.

Benefits of Using EV Calculations

  • Identify profitable betting opportunities
  • Make more objective betting decisions
  • Evaluate the true value of betting lines
  • Improve long-term betting results

Important Considerations

  • EV calculations depend on accurate probability estimates
  • Positive EV doesn't guarantee short-term profits
  • Consider using EV alongside other betting tools
  • Market efficiency can affect the availability of +EV bets

Note: While EV is a powerful tool, it's important to remember that your probability estimates must be accurate for the calculations to be meaningful. Always combine EV analysis with thorough research and sound bankroll management.
