What is Vig in Sports Betting?

We’ve spoken about how vital it is to have the finest odds available to become a successful sports gambler. Sometimes it’s not as simple as it seems. The expertise of sports betting lies in attempting to determine the actual odds of a result. How can you be certain that the price you are paying for your bet is accurate? When sports betting businesses are engaged in the same game, it is challenging. With appealing odds and promos, they are attempting to win your business, but they are also establishing markets to make sure their books are successful.

Sportsbooks like do this, among other things, by charging what is referred to as “vig.” It is also known as the rake, cut, juice, take, or commission and stands for “vigorish.” Because they are confident that they will make money regardless of the outcome, bookmakers will attempt to collect bets on all possible outcomes.

Even while “house advantage” is a more widely used phrase in the casino industry, it provides us with a crucial background in this situation. The vig is how a sportsbook generates money when people bet on sports. Sports betting websites must make money; therefore, they factor a little edge into each wager. We’ll explain the vig’s operation, calculation, and significance in the sections that follow.

What does “vig” mean?

Vig is short for vigorish, and both adjectives can be used in the same sentence. The odds for all bets include the vig amount. The vig is essentially a fee or commission that those online sportsbooks levy. It aids in ensuring that the book generates revenue regardless of how the game turns out. It thus directly affects the possible gains for bettors.

You won’t always double your money when you win a sports wager. This is due to the vig, which is effectively the fee the sportsbook levies for accepting bets. It is simply a fee charged by the sportsbook for taking the wager as part of normal business operations.

How to figure out the vig

Bettors with experience realize that an even wager would have no juice. It’s a very reasonable wager. The juice rises price the more it deviates from equilibrium.

In the case of a -110/-110 wager, for instance, the sportsbook will automatically take a larger cut than the EVEN wager. At -115/-110, the bookmaker has a chance to earn an even bigger share, and things may carry on indefinitely this way. Prop bets typically have even more juice attached; for example, depending on the sportsbook, either side of a player prop sits at -115 or even -120.

For novice sports bettors who may not fully comprehend juice, the good news is that it can be calculated. The juice % may be determined without even knowing how the event will turn out or how much money would be in danger.

Do bookmakers alter their vig?

The vig is changed by sportsbooks. This may seem puzzling to those who are new to sports betting. Why do sportsbooks occasionally alter it? Vig can be altered before the game’s real line is altered. Altering the vig may be a simple technique for a sportsbook to assure they will make more money without immediately changing the entire line if the money on a line is starting to get a bit problematic. Changing the vig often indicates that the line may be about to alter.


The foundations of the vig must be understood to be a successful bettor. In fact, before even considering the more intricate aspects of betting, it is crucial to comprehend all that has been described above. The amount of money the bettor will win from a stake depends on the vig. Vig can influence a bettor’s choice of side. Vig may even serve as a warning to potential bettors that the entire line is about to move.
