1. What is American Odds?

American odds (moneyline odds) are a way of expressing probability in sports betting. Positive odds show how much profit you'd make on a $100 bet, while negative odds show how much you need to bet to win $100.

2. How Does the Calculator Work?

The calculator uses the American odds formula:

Where:

• \( p \) — Probability (between 0 and 1)
• Negative odds indicate favorites (probability > 50%)
• Positive odds indicate underdogs (probability ≤ 50%)

Explanation: The formula converts probability to the American odds format used by bookmakers.

3. Importance of Odds Calculation

Details: Converting probability to odds helps bettors compare their assessment of likelihood with bookmakers' odds to find value bets.

4. Using the Calculator

Tips: Enter probability as a decimal between 0 and 1 (e.g., 0.75 for 75%). The calculator will return the corresponding American odds.
