Frequently Asked Questions
What is the vig (vigorish)?
The vig (also called juice, hold, or margin) is the bookmaker's built-in profit on a betting market. It's the difference between the true odds and the odds offered. Standard vig on a -110/-110 market is about 4.55%.
How does vig affect my bets?
The vig reduces your expected return on every bet. On a -110/-110 market, you need to win 52.4% of your bets just to break even. Lower vig means you need to win less often to be profitable.
What is a good vig percentage?
Standard vig is around 4-5% (-110/-110). Reduced juice books offer 2-3% (-105/-105). Betting exchanges can have vig under 2%. Lower is always better for bettors.
What are no-vig odds?
No-vig (or fair) odds are what the odds would be without any bookmaker margin. They represent the true implied probability of each outcome. Comparing actual odds to no-vig odds shows how much value you're giving up.
Why do different sportsbooks have different vig?
Sportsbooks compete on vig to attract bettors. Some offer reduced juice as a marketing strategy, while others maintain higher margins. Shopping for the best odds across multiple books can significantly improve your long-term results.
