If you’ve ever placed a bet or explored the world of sports betting, you’ve likely encountered the term “the vig.” But what exactly does it mean, and how does it impact your betting strategy? In this article, we’ll break down the meaning of the vig, explore its role in sports betting, and share tips on how to minimize its effect on your wagers. Plus, we’ll highlight how tools can help you automatically de-vig odds for better decision-making.

Vig Meaning: The Basics

The term “the vig” is short for “vigorish,” a word that originates from the Russian and Yiddish languages, meaning “winnings” or “take.” In the context of sports betting, the vig refers to the commission or fee that a sportsbook charges for facilitating a bet. It’s how sportsbooks ensure they turn a profit, regardless of the outcome of a game.
For example, if two teams are evenly matched, a sportsbook might set the odds at -110 for both sides. This means that a bettor must wager $110 to win $100. The extra $10 represents the vig—the sportsbook’s built-in profit.

Why Do Sportsbooks Charge the Vig?

Sportsbooks operate as businesses, and the vig is a primary revenue stream. By taking a small cut from every bet placed, they mitigate their risk and ensure profitability even when the betting public heavily favors one side of a matchup.
Without the vig, sportsbooks would be exposed to significant financial losses if most bettors correctly predicted the outcome of an event.

How to Calculate the Vig

Understanding the vig can give you a clearer picture of the true odds of an event. To calculate the vig, you can use this formula:
  1. Convert the American odds to implied probabilities using an implied probability calculator.
  1. Add the implied probabilities of both sides of the bet.
  1. Subtract 100% from the total to find the vig percentage.
 
Let’s break this down further with an example. Say the odds are -110 for both sides of a bet:
  • First, convert the odds to implied probabilities. To do this, divide 100 by the sum of the absolute value of the odds plus 100. For -110, the calculation is:
    • Implied Probability = 100 / (110 + 100) = 100 / 210 = 0.4762 (47.62%)
      This means each side of the bet has an implied probability of 47.62%.
  • Next, add the implied probabilities of both sides together:
    • Total = 47.62% + 47.62% = 95.24%
  • Finally, subtract this total from 100% to find the vig:
    • Vig = 100% - 95.24% = 4.76%
This 4.76% represents the sportsbook’s profit margin on this bet.
Alternatively, you can use a vig calculator to calculate the built-in juice:

How to Minimize the Vig

One of the best ways to improve your betting edge is to minimize the impact of the vig. Here are some strategies:
  1. Shop Around for Better Odds
    1. Different sportsbooks offer slightly different odds. Comparing multiple bookmakers can help you find lower-vig options.
  1. Bet on Reduced Juice Sportsbooks
    1. Some sportsbooks offer reduced vig, often called "reduced juice." For example, instead of -110, you might find odds at -105, which can make a significant difference over time.
  1. Use Tools to De-Vig Odds
    1. Advanced bettors often use tools to remove the vig from a sportsbook’s odds, revealing the true probability of an event.
 

Why De-Vigging Matters

De-vigging is the process of removing the sportsbook’s built-in profit margin to reveal the true implied probabilities of an event. This practice is especially useful with sportsbooks like Pinnacle, which is known for offering sharp odds and a low vig (often under 2%). By de-vigging Pinnacle’s odds, bettors can calculate the "no-vig price" (NVP), representing fair odds without the bookmaker’s commission. Comparing these no-vig odds with slower-moving lines at other sportsbooks can help identify valuable betting opportunities.
Services such as Pinnacle Odds Dropper automatically de-vig Pinnacle’s odds, giving users a benchmark to find positive expected value bets on other sportsbooks:
