Sportsbooks use vig and juice to make money by creating a built-in advantage in the odds they offer to customers. The vigorish, or vig, is the commission taken by the bookmaker on each bet, typically ranging from 4-10%. This means that for every $100 bet, the sportsbook keeps $4-10, regardless of the outcome of the event. The juice, on the other hand, is the percentage of the bet that is taken by the sportsbook, usually around 10%.
When a sportsbook sets its odds, it's not just a reflection of the true probability of an event occurring. Instead, it's a calculated number that ensures a profit margin for the bookmaker. For example, if a sportsbook sets an even-money odds on a game, say 50/50, it's actually offering odds of 47/53 or 48/52 in favor of the bookmaker. This means that for every $100 bet on that event, the bookmaker would expect to lose $47-48 and win $52-53.
The key to sportsbooks' success lies in their ability to set odds that attract an equal number of bets on both sides of an event. This ensures that they can collect the vig and juice without taking on significant risk. If they set an incorrect line and attract more bets on one side, they can adjust the odds to balance the action and maintain their profit margin. By using advanced analytics and market analysis, sportsbooks are able to make calculated decisions about which lines to set and how to adjust them in response to changing market conditions.
