Odds Expected Value Calculator

The expected value calculator helps you determine whether a bet has positive or negative expected value. A positive expected value indicates a profitable bet over time, while a negative expected value suggests you'll lose money in the long run.

To calculate expected value, you need to know the true probability of winning and compare it to the odds being offered. If your assessed probability is higher than the implied probability from the odds, you have positive expected value.

Expected value is calculated using the formula: EV = (Win Probability × Potential Earnings) - (Loss Probability × Stake). This tells you the average amount you can expect to win or lose per bet over many repetitions.
