If it’s a tight game, the odds for a home win, an away win, or a draw will all be similar. So, if the implied odds from all betting options total 107%, there’s an overround of 7%.Īn example of this could be a soccer game. The percentage points above 100 are the profit level the sportsbook is taking.

For each bet, a sportsbook will offer odds with implied odds of over 100%.

Overround betting is how a sportsbook makes a profit on bets it takes.
