How to Use

Using the calculator is straightforward. Input the necessary values in the provided fields, click the “Calculate” button, and the result will be displayed instantly. This tool is designed to streamline the process, making it accessible for users at various proficiency levels.


The expected opportunity loss (EOL) is calculated using the formula:


  • Probabilityloss​ is the probability of a loss occurring.
  • Amountloss​ is the potential amount of loss.
  • Probabilitygain​ is the probability of a gain occurring.
  • Amountgain​ is the potential amount of gain.

Example Solve

Suppose we have a situation where the probability of a loss is 0.3, the potential loss is $5,000, the probability of a gain is 0.7, and the potential gain is $8,000. Plugging these values into the formula:




The expected opportunity loss, in this case, is $4,100.
