How To Calculate Expected Value In Excel


Expected Value is a statistical measure that represents the average outcome of a probability distribution. It helps in assessing potential outcomes by considering the likelihood of each event. Calculating Expected Value in Excel can be a crucial tool for decision-making in various fields.

Formula: The formula for Expected Value is straightforward: multiply the probability of an event by its outcome value.

How to Use:

  1. Enter the probability of the event in the first input field.
  2. Enter the value associated with the outcome in the second input field.
  3. Click the “Calculate” button to get the Expected Value.

Example: Suppose you have a 30% chance of winning $100 in a game. Enter 0.3 for probability and 100 for the outcome. Click “Calculate” to find the Expected Value.


Q1: What is Expected Value? A1: Expected Value is the average outcome of a probability distribution, calculated by multiplying the probability of each event by its outcome value.

Q2: How is Expected Value useful? A2: It helps in decision-making by providing a single value that represents the average outcome considering probabilities.
