The EVPI (Expected Value of Perfect Information) Calculator is a powerful tool used to assess the potential value gained through obtaining perfect information in decision-making scenarios. It aids in evaluating the impact of uncertainties on the expected outcomes and helps decision-makers make more informed choices.
Formula of EVPI Calculator
The fundamental formula for calculating EVPI is as follows:
EVPI = (EVwPI - EVwoPI)
Where:
- EVPI represents the Expected Value of Perfect Information.
- EVwPI stands for the Expected Value with Perfect Information.
- EVwoPI stands for the Expected Value without Perfect Information.
This formula provides a quantitative measure of the potential value that perfect information could add to the decision-making process.

In this table:
- Scenario represents different decision-making situations (e.g., Market Research, Product Launch, Expansion Plan).
- EVwPI denotes the Expected Value with Perfect Information, considering the best possible outcomes.
- EVwoPI represents the Expected Value without Perfect Information, factoring in uncertainties.
- EVPI indicates the Expected Value of Perfect Information, calculated as the difference between EVwPI and EVwoPI.
Example of EVPI Calculator
Let’s consider a practical example to illustrate how the EVPI Calculator works in real-life scenarios.
Suppose a company is deciding whether to launch a new product. By using the EVPI Calculator, they can assess the potential value of obtaining perfect information about market demand, production costs, and competitor strategies. The calculator helps quantify the impact of uncertainties, enabling a more informed decision-making process.
