Starting Line Ratio Calculator

How to Use the Calculator

1. Enter the starting line in decimal odds format in the "Starting Line" field (e.g., 1.90 for -110 odds).
2. Click the "Calculate" button to compute the implied win probability and implied odds.
3. The results will show you the implied probability of the outcome winning and the odds against that outcome.

Understanding the Results

The calculator provides two key outputs:

• Implied Win Probability: This is the percentage chance of the outcome winning based on the odds provided. For example, if the implied win probability is 50%, there's a 50% chance of winning.
• Implied Odds: These represent the odds against winning. For instance, if the implied odds are 1.00, it means you get 1 unit of profit for every 1 unit bet if you win.

Principle Explanations

The calculator uses the following formulas:

Implied Win Probability = 1 / Starting Line

Implied Odds = Starting Line - 1

These calculations help bettors understand the true odds offered by bookmakers and compare them with their own assessment of probabilities.
