What is an Implied Probability Calculator?
An implied probability calculator translates betting odds into their underlying winning percentage. Every odds format reflects a built‑in chance of success, and this tool helps you uncover that number instantly. This quick‑reference version is designed for Colorado bettors and links back to the main Colorado Betting Hub homepage.
How Does the Implied Probability Calculator Work?
The calculator uses standard formulas to convert betting odds into implied winning probability. Once you input your odds, the tool automatically applies the correct formula based on the format.
Implied Probability Formulas
- American Odds
- Positive odds (e.g., +150):
- Probability = 100 / (American + 100)
- Negative odds (e.g., -150):
- Probability = |American| / (|American| + 100)
- Decimal Odds
- Probability = 1 / Decimal
- Fractional Odds
- Probability = Denominator / (Numerator + Denominator)
Example
- American odds:+200
- Probability =100 / (200 + 100) = 33%
Total Payout: At +200, a $100 stake returns $300 total.
