Most bookmakers use a -110 line on Over/Under betting, meaning for every $1.10 risked, you would win $1 or bet $110 to win $100. Like point spread betting, there is vig assigned to either side of the total. In the example below, if Kansas City wins by exactly three points, the bet is graded as a “push” and the original stake of the bet is refunded. For the underdog to cover the spread, it must win the game outright or lose by two points or fewer. The weaker team is the point spread underdog, with a positive value (+) next to its spread, such as +3.0. For the favorite to cover the spread, it will have to win the game by four or more points. It is indicated by a negative value (-) next to its spread, such as -3.0. The strong team is the point spread favorite. Oddsmakers calculate the perceived difference on the scoreboard between two teams and put that number as the spread to handicap the competition. Point spread bets require teams to win by more or lose by less than a set number of points. Using Covers' moneyline calculator lets you see how much you can win from other moneyline odds values, as well as implied probability. This underdog bet will return $1.10 for every $1 wagered or $110 on a $100 bet. A +110 moneyline underdog has an implied probability of 47.62 percent to win, and because there is more risk in betting the underdog to win, you can win more than you risk. The weaker team is listed as the moneyline underdog and will have a positive value (+) with its odds, such as +110.
