What Is Vig (Juice)?
Vig (short for vigorish, also called juice) is the commission the sportsbook charges on every bet. It's the reason standard lines are -110/-110 instead of +100/+100. The vig is how sportsbooks guarantee profit regardless of the outcome.
Break-Even Win Rate
At standard -110 odds, you need to win 52.38% of your bets just to break even. Any win rate above that is profit. This calculator shows you exactly what win rate you need for each side of a market.
Finding Low-Vig Lines
Shopping for the lowest vig across sportsbooks is one of the easiest ways to improve your long-term results. Even a small reduction in vig compounds into significant savings over hundreds of bets.
