Expected Value (EV) Calculator
Compare your true win probability to the offered odds to see if a bet is +EV.
Expected value is the average profit or loss you'd make per bet if you placed it many times. A positive EV means the price is bigger than the true probability warrants. It relies on your probability estimate being accurate — the more reliable your estimate, the more you can trust the result.
