What is the Vig (Juice)?
The vig (also called juice, margin, or hold) is the sportsbook's built-in commission. It's how they guarantee profit regardless of the outcome. When you see -110 on both sides of a spread, that extra 10 cents is the vig—you're paying $110 to win $100.
Why Vig Matters
- •A -110/-110 market has 4.55% vig—you need to win 52.4% of bets just to break even
- •Lower vig means more profit in your pocket over time
- •Some books offer reduced juice (-105) on spreads and totals
- •Line shopping can save you 1-2% vig per bet—huge over a season
