Implied probability is the likelihood of a selected bet being a winner based on the bet’s odds. A moneyline to percentage calculator will automatically provide this value to you when information is added correctly. This gives the user a better understanding of the bet’s statistical likelihood of being won.

Implied probability is calculated using a simple formula for each of the different odds types. American Odds requires two different formulas, one for negative and one for positive. The formulas for various odds types can be seen in the table below.

Positive American OddsImplied Probability = 100 / (Odds + 100) x 100
