Implied Probability Formula:
From: | To: |
Implied probability is the conversion of betting odds into a percentage that represents the likelihood of an outcome occurring. It's calculated as the reciprocal of the decimal odds.
The calculator uses the implied probability formula:
Where:
Explanation: The formula converts decimal odds into their implied probability equivalent.
Details: Understanding implied probability helps bettors assess whether a wager offers value by comparing it to their own estimated probability of an outcome.
Tips: Enter the decimal odds (must be greater than 1). The calculator will return the implied probability as a value between 0 and 1.
Q1: What's the difference between probability and implied probability?
A: Probability is the actual chance of an event occurring, while implied probability is what the odds suggest the chance is.
Q2: How do I convert implied probability to percentage?
A: Multiply the result by 100 (e.g., 0.25 → 25%).
Q3: What does it mean when implied probability is less than actual probability?
A: This suggests the odds may offer value, as the bookmaker is estimating a lower chance than you believe is accurate.
Q4: Can implied probability exceed 1?
A: No, the maximum implied probability is 1 (100%) when odds are 1.0.
Q5: Why do bookmakers' implied probabilities add up to more than 100%?
A: The overround (vigorish) is how bookmakers ensure profit, making the total implied probability exceed 100%.
