**What Is The Definition Of Vigorish In Sports Betting?**

1. The vigorish, or vig, is the extra charge included on top of the odds in order for the sportsbook to earn a profit. In slang, this difference is referred to as the juice.

**How Do You Calculate Vigorish?**

Sportsbooks normally don’t publish the vig, so the best way to learn how to calculate it is through an example.

For instance, in the 2021 Cotton Bowl, a semifinal matchup between the **Cincinnati Bearcats** and the **Alabama Crimson Tide**, the **moneyline** looks like **this**:

- Bearcats +425
- Tide -600

Alabama holds the favorite selection, while Cincinnati is the underdog. In order to win $100 on the Tide, **wagers** need to be $600. Wagering $100 on the Bearcats would net $425 if they win.

To figure the vig, you need to find the implied probability of risk/return based on the odds, and then find the surplus. That surplus is the vig. You can use the following **formula** to calculate the probability and then the vig:

- Favorite probability = Favorite Odds/(Favorite Odds + 100) * 100
- Underdog probability = 100/(Underdog Odds +100) * 100
- Vig = (Favorite Probability + Underdog Probability) – 100

Using this formula, the probabilities and vig calculations look something like this:

- Alabama probability = 600/(600 + 100) * 100 = 85.71%
- Cincinnati probability = 100/(425 + 100) * 100 = 19.05%
- Vig = 85.71% + 19.05% = 104.76 – 100 = 4.76%

**How Does A Vig Work?**

In theory, sportsbooks would set the line to draw even bets on the two outcomes. The odds set in this line, however, do not often add up to 100%. This difference would be the unbiased profit for the sportsbook.

For this reason, a lot of bets hold the -110 line. In order to profit $100, $110 must be wagered. This $10 difference is the vig or juice.

**What Is A Normal Vig?**

A normal vigorish is somewhere under 5% of the total projected profit, usually **4.76%**.

In the standard -110 odds, betting $110 would net $100 in addition to the wagered amount, resulting in a profit of $210 if the bet hits.

The $10 wagered on top of the $100 earned and wagered is the juice. Accordingly, $10/$210 = 4.76%.

**How Do You Remove Vig Odds?**

Removing vig odds is simple if the calculations above are already complete.

Otherwise, you can do this by making the implied probabilities a fraction of the total probability (including the vig). Thus, the probability without the vig for each team would look like this:

- Alabama = 85.71/104.76 = 81.82%
- Cincinnati = 19.05/104.76 = 18.18%
