Juice (also called vig or vigorish) is the commission a sportsbook charges for taking your bet. On spread bets, it's the reason both sides are usually priced at -110 rather than +100.
The Standard -110 Explanation
Both sides of a spread at -110:
- You bet $110 to win $100
- If the book takes equal action on both sides, they collect $220 total
- They pay $210 to the winners (stake + profit)
- They keep $10 = ~4.5% margin
Juice Variations
- -105/-105: Reduced juice books (BetUS, CRIS). Lower margin, better for bettors.
- -110/-110: Standard retail sportsbook pricing
- -115/-105: Asymmetric juice. One side is more expensive because public money favors it
- -120/-100: Sharper asymmetry — one side is clearly being shaded
How Juice Affects Break-Even Win Rate
| Juice | Break-Even Win Rate | |———-|——————————-| | -105 | 51.2% | | -110 | 52.4% | | -115 | 53.5% | | -120 | 54.5% |
At -120, you need to win more than 54.5% of bets just to break even. This is why juice matters even when you're finding good picks.
