Hold/Vig Calculator

Calculate the sportsbook's hold (vig) and see the true no-vig fair odds for both sides.

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.

Responsible Gambling

Gambling should be entertaining, not a way to make money. Only bet what you can afford to lose, and never chase your losses.

Signs of problem gambling:
  • Betting more than you can afford to lose
  • Chasing losses with bigger bets
  • Lying to others about gambling habits
