Understanding the Vig

The vig (vigorish) or hold is the sportsbook's built-in profit margin. Standard -110/-110 odds have about 4.5% vig. Lower vig means better value for bettors.

Shop for the Best Lines: Different books have different vig. Finding reduced juice (-105) instead of standard (-110) can significantly improve your long-term results.

Frequently Asked Questions

What is vig (vigorish) in sports betting?

Vig, also called juice or vigorish, is the sportsbook's built-in profit margin. Standard -110/-110 odds have about 4.55% vig. The vig ensures the sportsbook profits regardless of the outcome. Lower vig markets (like -105/-105) offer better value for bettors.

How do you calculate the vig on a bet?

Add the implied probabilities of both sides. If the total exceeds 100%, the difference is the vig. Example: -110 odds = 52.38% implied probability. Both sides at -110 = 104.76% total, so the vig is 4.76%. Our calculator does this math instantly.

What is a good vig percentage?

Standard sportsbook vig is 4-5% on spreads and totals (-110/-110). Reduced juice books offer 2-3% (-105/-105). The best sharp books like Pinnacle may have vig under 2% on major markets. Lower vig means more money in your pocket long-term.

How does vig affect my betting profits?

Vig directly impacts your break-even win rate. At -110 odds, you need to win 52.4% to break even. At -105 odds, you only need 51.2%. Over thousands of bets, this difference is significant. Always shop for the lowest vig to maximize long-term profits.

What are no-vig fair odds?

No-vig fair odds remove the sportsbook's margin to show true market probabilities. If fair odds are +105 but a book offers +115, you have value. Sharp bettors use no-vig odds from Pinnacle as a benchmark to identify +EV opportunities at other books.
