Free +EV Betting Calculator

Calculate expected value on any bet.

A bet has positive EV when the true probability of winning is higher than the bookmaker's implied probability. Enter the bookmaker's decimal odds, the fair odds or fair probability, and your stake to see EV% and expected profit.

EV% is calculated as: (your odds / fair odds - 1) × 100. A positive EV% means the bet returns more than its cost on average.

VigBreak detects positive EV bets automatically across major bookmakers. See live signals or read what +EV betting is.
