No Vig Fair Odds Calculator

Sports betting odds offered by bookmakers include something called the vig (also known as overround, juice, or margin). This is essentially the bookmaker’s built-in profit margin. While odds may appear fair, they are slightly skewed to ensure the house always has an edge.

The No Vig Fair Odds Calculator is a tool designed to strip away this hidden margin. It recalculates the true probabilities and fair odds, giving bettors a clear picture of the real chances of each outcome. By doing so, it helps identify value bets, improve betting strategies, and reduce the impact of the bookmaker’s edge.

How to Use the No Vig Fair Odds Calculator (Step-by-Step)

The calculator is straightforward to use. Follow these steps:

1. Enter Odds for Outcome A
   • Input the decimal odds offered by the bookmaker for the first outcome (e.g., Team A to win at 2.10).
2. Enter Odds for Outcome B
   • Input the odds for the second outcome (e.g., Team B to win at 1.80).
3. Choose Market Type
   • Select whether the bet is a two-way market (e.g., tennis match winner, basketball moneyline) or a three-way market (e.g., soccer 1X2, where a draw is possible).
4. (Optional) Enter Odds for Outcome C
   • If it’s a three-way market, add the odds for the third outcome (usually the draw, e.g., 3.50).
5. Click “Calculate”
   • The tool will show:
     • Implied probabilities with vig included.
     • The total market percentage (usually >100% because of the vig).
     • Adjusted “no vig” probabilities (true probabilities).
     • Fair odds for each outcome.
6. Review the Results
   • Compare the fair odds to the bookmaker’s offered odds. If the bookmaker’s odds are higher than the fair odds, you may have found a value bet.
7. Copy or Share Results
   • Use the built-in buttons to copy or share the calculations for record-keeping or strategy discussions.

Practical Example: Removing the Vig from a Soccer Match

Imagine a soccer match between Team A vs Team B, with the following bookmaker odds:

• Team A to win: 2.10
• Team B to win: 1.80
• Draw: 3.50

Step 1: Implied Probabilities (with vig)

• Team A: 1 / 2.10 = 47.62%
• Team B: 1 / 1.80 = 55.56%
• Draw: 1 / 3.50 = 28.57%
• Market Total: 131.75% (includes bookmaker margin)

Step 2: Adjusted No-Vig Probabilities

• Team A: 47.62 ÷ 131.75 = 36.14%
• Team B: 55.56 ÷ 131.75 = 42.15%
• Draw: 28.57 ÷ 131.75 = 21.71%

Step 3: Fair Odds (No Vig)

• Team A: 1 ÷ 0.3614 = 2.77
• Team B: 1 ÷ 0.4215 = 2.37
• Draw: 1 ÷ 0.2171 = 4.61

Takeaway: The bookmaker’s odds undervalue Team A significantly. According to fair odds, Team A should be priced at 2.77, but the bookmaker offers 2.10. This means betting on Team A is poor value. However, if another bookmaker offered 3.00, it would represent a strong value bet.
