EMV Formula

Calculates the average outcome if the scenario were repeated many times. It helps in making decisions under uncertainty.
EMV = (Best Case × Probability) + (Worst Case × (1 - Probability))

Variables:

Best CaseFinancial outcome if things go well
Worst CaseFinancial outcome if things go poorly
ProbabilityLikelihood of the best case occurring (%)

Example

Product Launch

Inputs:

Best Case:$100,000 (Success)
Worst Case:$20,000 (Failure)
Probability:60% chance of success

Steps:

  1. 1.Weighted Best = $100,000 × 0.60 = $60,000
  2. 2.Weighted Worst = $20,000 × 0.40 = $8,000
  3. 3.EMV = $60,000 + $8,000 = $68,000
Result:
Expected Value: $68,000

Frequently Asked Questions

What is EMV used for?

Risk management and decision making. It helps compare different projects with varying risks and rewards on an equal footing.

Should I always choose the highest EMV?

Not necessarily. EMV assumes you are risk-neutral. If the 'Worst Case' is bankruptcy, you might avoid the risk even if the EMV is high.

How do I estimate probability?

Use historical data, market research, expert opinion, or industry benchmarks. Sensitivity analysis (testing different probabilities) is recommended.
