Implied Probability | Sports4Play Guide

Convert betting odds into the break-even probability implied by the market price.

Why Convert Odds

Implied probability turns a price into an intuitive percentage. It helps compare your estimated chance of an outcome with the chance embedded in the market.

Negative American Odds

For negative odds, implied probability = |odds| / (|odds| + 100). At -110, the implied probability is about 52.4% before considering market margin.

Positive American Odds

For positive odds, implied probability = 100 / (odds + 100). At +150, the implied probability is 40%.

Decimal Odds

For decimal odds, implied probability = 1 / decimal odds. A decimal price of 2.00 implies 50%. Market prices often contain margin, so the probabilities across all outcomes can add to more than 100%.
