Money lines represent the amount you would win on a $100 bet. Positive numbers indicate favorites, while negative numbers indicate underdogs.
Formula
To convert a money line to a percentage:
If the money line is positive (favorite):
Percentage = (100 / (Money Line + 100)) × 100
If the money line is negative (underdog):
Percentage = (100 / (100 - Money Line)) × 100
This formula calculates the implied probability of the bet winning based on the money line.
