Vig / Vigorish

What sportsbook vig means and how it appears in market pricing.

Updated 2026-08-30Gambling Online Editorial Team3 min read
Quick answer

Vig, vigorish or juice refers to the sportsbook’s pricing margin or commission embedded in betting odds.

Why it matters

A bettor must overcome the price, not merely pick outcomes correctly.

Example

Two sides both offered at 1.91 imply probabilities totaling about 104.7%, creating a raw overround above 100%.

Related terms

Overround, hold, implied probability and break-even probability are closely related but not always interchangeable.
