What is No Juice Calculator?
The No Juice Calculator, also known as a NoVig calculator or Fair Odds Calculator, is used to remove the bookmaker's profit margin, or "juice", from betting odds. This tool is valuable for bettors looking to understand the true probability of an event outcome, stripped of the sportsbook's built-in advantage.
By inputting the betting odds for each side of a wager, the No Juice Calculator adjusts these odds to reflect a market with no bookmaker margin, showing what the "fair odds" would be. This is particularly useful for comparing odds across different sportsbooks and assessing the value of bets.
How to Use the No Juice Calculator
1. Select the Odds Type you are using (American or Decimal).
2. Enter the odds for each outcome of the event. For a typical two-outcome market (like a moneyline bet), you will enter two sets of odds. You can add more outcomes if necessary using the "Add Bet" button.
3. Click the "Calculate Vig" button to compute the no-juice probabilities and the bookmaker's hold.
4. Review the "No Vig Percentage" for each outcome to see the probabilities without the bookmaker's margin. The "Bookmaker Hold" indicates the total percentage of profit margin the bookmaker has built into the odds.
Example
Example: In a hypothetical Lakers vs. Mavericks game, with the Mavericks favored:
- Mavericks -130 (56.52% chance of winning if American odds, or equivalent decimal odds)
- Lakers +110 (47.62% chance of winning if American odds, or equivalent decimal odds)
The combined chances exceed 100% (104.14%), demonstrating the 4.14% profit margin (hold) the bookmaker applies to this game.
Note: This calculator assumes that the vig is equally distributed across all outcomes. However, in reality, bookmakers might distribute their margins unevenly. For example, 90% of the hold could be on one outcome and only 10% on another. This uneven distribution can lead to inaccuracies in the calculated no-vig probabilities.
Frequently asked questions
What is vig (juice)?
Vig is the sportsbook margin built into every price. On a coin-flip market both sides are typically -110, so the implied probabilities sum above 100% — that excess is what the book earns regardless of the result.
How does the calculator remove the vig?
It converts both prices to implied probabilities and normalizes them so they sum to exactly 100%. The result is the fair, no-vig price the market is really quoting behind the margin.
What do I use no-vig prices for?
They are the standard baseline for estimating true win probability, which feeds EV and Kelly calculations. Comparing a price at your book against the no-vig line at a sharp book is the simplest positive-EV workflow.
Are no-vig prices the true probability?
They are a market estimate, not truth. The tighter and sharper the market you strip the vig from, the closer the result tracks real probability — no-vig prices from a sharp book are a much better proxy than from a recreational one.
