Vig Calculator

Vig (vigorish, or juice) is the commission a sportsbook builds into its prices. At the standard -110/-110, each side implies 52.38%, the market sums to 104.76%, and the extra 4.76% is what the book keeps. Enter both sides of any market and this calculator shows the exact vig you are being charged.

Vig varies more than most bettors realize, from around 2% on heavily traded main markets to well over 10% on exotic props. Since every point of vig comes directly out of your long-run returns, comparing juice across books for the markets you bet most is one of the simplest ways to improve your bottom line.
