EV Calculator

Calculate EV and EV% to see whether a bet is +EV or -EV based on your projected win probability.

Expected Value (EV) is the average profit or loss you should expect over the long run. Positive EV suggests a bet is worth considering; negative EV suggests you’re paying too much for the price.

This calculator shows EV (in dollars), EV%, and the break-even win probability implied by the odds.
