What Is Expected Value in Betting?
Expected value (EV) is the average amount you expect to win or lose per bet if you placed the same wager thousands of times. A positive EV (+EV) bet is profitable long-term; a negative EV (-EV) bet is not.
The Formula
EV = (Win Probability × Win Amount) - (Loss Probability × Stake)
Example
You find a +150 line that you believe has a 45% chance of hitting. Win amount on a $100 bet = $150. EV = (0.45 × $150) - (0.55 × $100) = $67.50 - $55 = +$12.50. This is a +EV bet worth taking.
