Expected Value Calculator

Expected value is what a bet earns on average if you could place it a thousand times. It compares the price you're offered against the fair price — what the bet is actually worth once the sportsbook's margin is stripped away. Beat the fair price and the bet is +EV: profitable in the long run even though any single result can go either way.

Enter your stake, the odds you can get, and the fair odds — the no-vig calculator produces those from a sharp market's two sides. The result is your average profit per bet in dollars and as a percentage of stake. A consistent +2% edge compounds into real money; a −5% habit quietly does the opposite. EV is the honest scoreboard behind every strategy on this site.
