How to Ace Customer Acquisition Cost Questions on Your Exam

Let's be brutally honest: Customer Acquisition Cost is usually taught terribly in textbooks. You don't need to be a genius to master this; you just need to understand one specific mental model.

Inside the Professor's Mind

Professors don't write Customer Acquisition Cost questions to test your basic memorization. They write them to test if you will fall for the classic pitfall: ignoring churn rate when calculating lifetime value.

When you sit down for the exam, write that specific trap at the top of your paper so you don't forget it.

What A Correct Answer Looks Like

If it costs $50 to acquire a customer (CAC), and they pay $10 a month, you need them to stay for 5 months to break even. If your churn is high, you lose money.

If your scratch paper doesn't look like that, you are losing points.
