How to Use the No-Vig Fair Odds Calculator
The Betstamp No-Vig Calculator helps you find the “fair” odds behind any two-sided betting market. By removing the vig (also called juice or margin), this tool shows the true win probability for each side — a key step in determining if a bet offers value.
Most sportsbooks bake a hidden edge into every line. This calculator reveals what the odds would be without that margin, helping you compare markets more accurately and spot mispriced lines.
Quick Start:
- Select your odds format (American, Decimal, or Fractional).
- Input the best available odds for both sides of the market.
- The calculator will display:
-
- No-Vig %: the adjusted win probability for each side
- Fair Odds: the true odds if there were no juice included
Example:
Let’s say you’re comparing odds on a college football game. One sportsbook lists Oregon at -180 and the opposing team at +150.
The implied win probabilities are:
- Oregon: 64.3%
- Opponent: 40.0%
(These add up to 104.3%, meaning the sportsbook has a 4.3% edge.)
After entering both odds, the calculator removes that edge and shows the fair probabilities:
- Oregon: 61.6%
- Opponent: 38.4%
It then converts those into fair odds:
- Oregon: -160
- Opponent: +160
This tells you what the line should be in an efficient, no-vig market. If you can find odds better than those fair prices, you're betting with an edge.
