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 the vig (vigorish)?

The vig, also called juice or hold, is the sportsbook's built-in profit margin. It's the difference between the true odds and what they offer. Standard -110/-110 odds have about 4.55% vig.

What is a good vig percentage?

Lower is better for bettors. Standard vig is 4.5-5% for spreads and totals. Reduced juice books offer 2-3% vig (-105 odds). Betting exchanges can have less than 2% commission.

How does the vig affect my bets?

The vig means you need to win more than 50% of even-money bets to profit. At -110 odds, you need 52.4% winners to break even. Lower vig reduces this requirement.

What are no-vig fair odds?

No-vig odds remove the sportsbook's margin to show the true fair price. If the market odds are -110/-110, the no-vig fair odds would be +100/+100 (50% probability each).
