What is Vig (Vigorish) in Sports Betting?

The vig, or vigorish (commonly called "juice"), is the commission built into betting odds that ensures the sportsbook makes a profit regardless of the outcome.

It’s calculated as the amount by which implied probabilities exceed 100%. A standard -110/-110 line carries a vig of about 4.76%—meaning the book keeps ~$4.76 of every $100 wagered on average.

Lower vig (e.g., -105/-105 ≈ 2.38%) means sharper books and better value for bettors.

How to Use the Vig Calculator

Once you understand the house edge on individual lines, you can make smarter decisions—especially when building multi-leg bets. For example, combining several legs with high vig dramatically reduces your expected value. Use our Parlay Calculator to see exact payouts and effective odds when combining multiple selections, helping you weigh whether the potential reward justifies the compounded juice.
