    Vig Explained

    Vig, vigorish or juice is the commission the sportsbook charges to facilitate the placing of bets and to ensure that it makes money on each wager. The bookmaker achieves this by offering odds that are lower than those reflecting the real probability of an outcome. In other words, if the real odds for a bet are 2.00, the bookie might offer 1.90. The vig is the difference between the real odds and the prices the bookmaker gives you for a particular market. 

    Let's explain this in more detail. Let's say you are betting on the match between PSG and Real Sociedad and placing a bet on the moneyline market. The odds are as follows:

    • PSG 1.65
    • Draw 4.15
    • Real Sociedad 5.15

    The odds you see in the example above are adjusted with the vig calculated in them. But how much is the vig for this moneyline market? You can check by trying to win $100 from a budget of $100 by betting on all outcomes:

    • PSG 100/1.65 = 60,6
    • Draw 100/4.15 = 24.1
    • Real Sociedad 100/5.15 = 19.4

    The combined implied probability of the three potential outcomes in this 3-way market is 104.1 (60.6 + 24.1 + 19.4). So, to win $100, you need to bet $104.1. In other words, the vig or bookmaker's commission for this moneyline market is 4.1%. Most top online sportsbooks have vigorish ranging from 3% to 5%.

    As you can see, regardless of the result, the bookmaker will always have an advantage over bettors because of the vig. That's why the vig is also referred to as house edge, as it is a way for the betting site to have an edge over bettors.

    Vig Sports Betting Examples - How is Vig Calculated

    Before you join online sportsbooks or place your bets, we strongly recommend that you calculate the vigorish for the market you want to wager on. The lower the vig, the better your potential winnings. Here's how you can calculate the house edge of a sports betting line.

    You first have to find out the implied probability of all of the possible outcomes in a market. Then add them together and subtract 100 from that number. That will give you the sports betting site's vig for that line. For example, if you are wagering on the NBA game between the Miami Heat (-2.5) and the Orlando Magic (+2.5), these are the point spread odds you will get

    • Miami Heat (-2.5) 1.95
    • Orlando Magic (+2.5) 1.90

    Those odds may seem enticing, but they come with the vig calculated in them. Let's see how high that house edge is by following the simple formula mentioned above. Let's first determine the implied probability:

    • Miami Heat 100/1.95 = 51.3
    • Orlando Magic 100/1.90 = 52.6

    The combined implied probability of the two outcomes in this 2-way market is 103.9 (51.3 + 52.6). To get the vig, subtract 100 (103.9 - 100) and you will get 3.9. In other words, the bookie has a 3.9% house edge on the point spread market.

    So, if you are trying to cover all outcomes and win regardless of the result, you should bet $51.3 on Miami winning and $52.6 on Orlando triumphing. Whichever bet wins, you will get the same payout of $100. However, you will have spent $103.9. That's how the online sportsbook ensures it has an edge on all bets you place.

    Strategies and Tips for Vigorish Betting

    Online sportsbooks will always have a small advantage over punters. After all, if they didn't put that profit margin in place, they wouldn't be able to operate as a sustainable business and would soon shut down shop. So, for all the money in winning bets bookmakers need to pay out, they will get more profits from losing wagers. That said, there are ways and betting strategies that increase your chances of being the winning bettor and not the punter funding the sportsbook's business growth.

    Different bet types come with different house edges. Even in the examples above, which were both from the same bookmaker, the vigorish for the moneyline and point spread markets were different. Usually, moneyline (1X2), point spread, and Over/Under total bets have lower vig than other, more exotic betting options. Knowing which market comes with reduced vigorish can go a long way when aiming for a sustainable sports betting adventure.

Similarly, if a bookmaker has enhanced odds bonuses, you will get competitive odds even when the sportsbook uses a steeper profit margin. Some betting sites aptly name these promos as No Vig or Zero House Edge bonuses, meaning you might even bet on events without having to deal with the vigorish.
