No-Vig Fair Odds Calculator

What are No-Vig Fair Odds?

No-vig fair odds represent the true probability of outcomes without the sportsbook's built-in profit margin. By removing the vig, you can see what the odds would be in a perfectly efficient market and identify potential value bets.

This calculator removes the bookmaker's margin from any two-way market to reveal the fair odds and true probabilities, helping you make more informed betting decisions.

How to Use This Calculator

The No-Vig Fair Odds Calculator helps you determine the true probabilities and fair odds by removing the bookmaker's margin (vig) from the odds.

  • Odds 1: Enter the first odds in American format (e.g., -110)
  • Odds 2: Enter the second odds in American format (e.g., -110)

This calculator will show you:

  • The true probability for each outcome (without the vig)
  • The fair odds for each outcome (without the vig)

Note: The calculator assumes that the bookmaker has balanced the market. The sum of the implied probabilities will be greater than 100% due to the vig, and this calculator removes that margin to show you the true probabilities.

Tips & Best Practices
  • Use no-vig probabilities to identify value bets by comparing with your own estimates.
  • Fair odds help you understand what odds would be offered in a zero-margin market.
  • Compare no-vig odds across different sportsbooks to find the best available prices.
  • This tool works best with two-way markets like moneylines, spreads, or totals.
