Expected value, or EV, is the average amount a bet would win or lose if you could place it many times over. A positive EV bet is one where your estimated chance of winning beats the price the book is offering, which is the only reliable way to profit from betting in the long run. This calculator asks for your true win probability, the odds in American or decimal form and your stake, then returns the expected value in money, the EV as a percentage of your stake and the break even probability the odds imply. Compare the implied probability to your own and you can instantly see whether a line has value. Everything computes locally in your browser.
