1. What is Vig Free Odds?

Vig Free Odds represents the true probability of an event occurring after removing the bookmaker's commission (vigorish). It provides a more accurate reflection of the actual odds without the bookmaker's margin.

2. How Does the Calculator Work?

The calculator uses the Vig Free Odds formula:

Where:

• \( Odds \) — Bookmaker's decimal odds
• \( Vig \) — Bookmaker's commission (0-1)

Explanation: The formula adjusts the bookmaker's odds by removing their built-in profit margin, showing what the odds would be without the vig.

3. Importance of Vig Adjustment

Details: Understanding vig-free odds helps bettors identify value bets by comparing the adjusted odds to their own probability assessments.

4. Using the Calculator

Tips: Enter the bookmaker's decimal odds (must be >1.00) and the estimated vig (typically 0.05-0.10 for most markets). The calculator will show the vig-free odds.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical vig percentage?
A: Most bookmakers use 5-10% vig, with lower margins on popular markets and higher margins on niche markets.

Q2: How do I find the vig in odds?
A: For two-outcome events, vig can be calculated as (1/odds1 + 1/odds2 - 1). For multi-outcome events, sum the implied probabilities and subtract 1.

Q3: Why are vig-free odds important?
A: They allow bettors to compare odds across bookmakers on a level playing field and identify which bookmaker offers the best value.

Q4: Do all bookmakers use the same vig?
A: No, vig varies by bookmaker, market, and event. Sharp bookmakers typically have lower vig than recreational ones.

Q5: Can vig-free odds be negative?
A: No, vig-free odds should always be positive and higher than 1.00 (for decimal odds).
