This case tests financial modeling ability and strategic thinking under uncertainty. The NPV calculation yielding zero is intentionally designed to push interviewees beyond quantitative analysis toward qualitative strategic considerations like diversification and competitive positioning.

Our client is the owner of a gas station between towns A and B – 10 miles to each town. He is wondering if it would make sense to add a convenience store to the gas station.

  2. Gas is 75% of revenue (10% profit margin) and the gas station also offers car washes (25% of revenue, 20% profit margin)

A gas station owner must decide whether to invest $1M in adding a convenience store. The quantitative analysis shows an NPV of zero (annual profit of $100K divided by 10% discount rate equals the $1M investment), forcing candidates to evaluate strategic factors like diversification, customer acquisition, and competitive defense.

Key Insights:

  1. When NPV = 0, the decision hinges on strategic factors beyond pure financial returns
  2. Market sizing requires methodical customer base calculation: population × car ownership % × market share
  3. Convenience store profitability combines existing customer incremental spend ($320K) with new customer attraction ($150K)
  4. High upfront capital requirements ($1M) create significant risk relative to return on investment
  5. The case rewards candidates who recognize that NPV = 0 is a boundary condition requiring qualitative judgment on diversification and competitive positioning
