Novig (No-Vig) Odds Calculator
Results
In sports betting, odds are rarely “fair.” Bookmakers include a built-in profit margin known as the vig (or juice), which slightly inflates probabilities and reduces bettor value. The Novig Odds Calculator is a powerful tool designed to remove this margin and reveal the true or “fair” probabilities of each outcome.
This tool is especially useful for bettors, analysts, and anyone who wants to understand the real implied chances behind betting lines. By converting American odds into probabilities and adjusting for vig, it provides a clearer picture of the actual market expectation.
Whether you’re betting on football, basketball, tennis, or any two-outcome event, this calculator helps you make smarter, data-driven decisions.
What is the Novig Odds Calculator?
The Novig Odds Calculator is an online tool that:
- Converts American odds into implied probabilities
- Calculates the bookmaker’s vig (margin)
- Removes the vig to show true no-vig probabilities
- Converts adjusted probabilities back into fair American odds
It works specifically for two-outcome markets, such as:
- Team A vs Team B
- Over vs Under (when simplified into two sides)
- Win/Loss matchups
This makes it an essential tool for sports bettors who want to evaluate value bets accurately.
How to Use the Novig Odds Calculator (Step-by-Step)

Practical Example
Let’s say you are analyzing a basketball game:
- Team A Odds: -120
- Team B Odds: +100
After entering these values, the calculator will:
Implied Probabilities:
- Team A: 54.55%
- Team B: 50.00%
Total Probability:
- 104.55% (This shows the vig)
Vig:
- 4.55%
No-Vig Probabilities:
- Team A: ~52.20%
- Team B: ~47.80%
Fair Odds:
- Team A: adjusted closer to -109
- Team B: adjusted closer to +109
This reveals that the sportsbook has built in a margin, and the real “fair” odds are more balanced than the listed lines suggest.
