Expected Loss
Statistical estimate of the average loss anticipated over a specified period, calculated as probability of occurrence multiplied by impact magnitude.
Full definition
Expected Loss represents the mean value of potential losses, computed by multiplying the probability of each loss scenario by its financial impact and summing across all scenarios. It serves as a baseline risk metric for capital allocation, pricing, and reserve setting. In credit risk, Expected Loss equals Probability of Default × Loss Given Default × Exposure at Default. An institution with a 2% default probability, 40% loss severity, and $1 million exposure has an expected loss of $8,000. Unlike worst-case measures, expected loss reflects the average outcome over many periods, making it suitable for provisioning but insufficient for capital planning, which must address unexpected losses and tail risks.
