How to Use This Calculator

1. Enter the gain, P (probability of success), and V (value of the prize) for your decision tree.
2. Click ‘Calculate’.
3. View your results in the ‘Results’ section.

Formula & Methodology

The formula for calculating EMV is: EMV = P * (Gain + V) – (1 – P) * Loss. In this calculator, we assume the loss is 0, as we’re focusing on the potential gains.
