How to Use the No Vig Calculator

The No Vig Calculator is designed to help you analyze betting odds and calculate potential profits under fair conditions without the built-in bookmaker’s margin (vig or juice). This guide provides a step-by-step walkthrough for using the calculator effectively.

Step 1: Input American Odds

  • Locate the American Odds input field. This is where you will enter the odds in American format, which can either be positive (e.g., +150) or negative (e.g., -110).
  • Enter the American odds into the American Odds field. Ensure the value is between -10,000 and 10,000.
  • Note that this field is required, so make sure to enter a valid number to proceed.

Step 2: Input Bet Amount

  • Find the Bet Amount ($) input field where you will specify the amount of money you plan to bet.
  • Enter the desired bet amount as a positive number. The minimum accepted amount is $0.01.
  • This field must be filled out to allow the calculator to process the calculations.

Step 3: View Calculated Results

Upon entering the required input fields, the calculator will automatically compute and display several key metrics to help you understand the bet better:

  • Decimal Odds: This represents the odds in decimal format and is calculated based on the American odds value. Positive odds are computed as americanOdds/100 + 1, while negative odds are calculated as 100/abs(americanOdds) + 1.
  • Implied Probability: The implied probability is expressed as a percentage and indicates the likelihood of the outcome as implied by the American odds. The calculation is different for positive and negative odds, with formulas as 100/(americanOdds + 100) * 100 or (abs(americanOdds)/(abs(americanOdds) + 100)) * 100, respectively.
  • Fair Odds (No Vig): These odds are adjusted to remove the bookmaker’s margin, providing a “fair” assessment of the bet. The formula used is 100/impliedProbability * 100.
  • Potential Profit: For positive American odds, this is calculated as (betAmount * americanOdds/100). For negative odds, it’s calculated as (betAmount * 100/abs(americanOdds)).
  • Fair Value Bet Amount: This value suggests the amount of your bet that constitutes “fair value” based on the implied probability, calculated as betAmount * (impliedProbability/100).

With these steps, the No Vig Calculator provides comprehensive insights and helps in making an informed decision on placing your bet.
