Bookmaker Fee Calculator (Vig)
Understanding Sportsbook Vig and Juice
Vig (short for vigorish), also called juice or margin, is the commission sportsbooks charge for accepting your bets. It's built into the odds and represents the bookmaker's profit margin. Understanding vig is crucial for finding the best betting value and choosing the most competitive sportsbooks.
Lower vig means better odds for bettors. While the standard vig in American sports betting is around 4.5% (e.g., -110 on both sides), sharp sportsbooks often offer reduced juice at -105 or better. Even small differences in vig compound significantly over thousands of bets.

What is Vig?
Vig (short for vigorish) or "juice" is the commission charged by sportsbooks. It's their built-in profit margin. A fair coin flip would be +100/+100 (50%/50%), but books typically offer -110/-110, creating a 4.55% vig.
Lower vig = better value. Shopping for the lowest vig across sportsbooks can significantly improve your long-term profitability.
