Expected Value (EV)
Expected value (EV) is a concept used in sports betting that describes the average expected return a bettor can anticipate from a wager over the long term. It is a mathematical value that takes into account the probability of different outcomes and the odds assigned to them.
To calculate expected value, you multiply the probability of a win by the odds for a given outcome, and then sum these values across all possible outcomes.
For example, if the odds for Team A to win are 2.5 and the probability of that outcome is 40%, the expected value equals 1.0 (i.e. 2.5 × 0.4).
Expected value can be useful when assessing whether a particular bet is potentially worthwhile and can help support decision-making about whether to place a bet.
However, it is important to remember that expected value is only one of many factors that should be considered when making betting decisions.
