How It Works
American (negative): IP = |odds| / (|odds| + 100). Example: -110 means 110 / 210 = 52.38%.
American (positive): IP = 100 / (odds + 100). Example: +150 means 100 / 250 = 40.00%.
Decimal: IP = 1 / decimal. Example: 1.91 means 1 / 1.91 = 52.36%.
Fractional (a/b): IP = b / (a + b). Example: 3/2 means 2 / 5 = 40.00%.
Implied probability tells you the minimum win rate you need to break even at given odds. If your estimated probability is higher than the implied probability, you have a value bet.
