Show Notes

In this episode of The Product Handbook, we break down the core unit economics every product manager should understand — Customer Acquisition Cost (CAC), Customer Lifetime Value (CLV), and payback period.

You’ll learn: How to calculate CAC, CLV, and payback period — and why these numbers matter for product and business strategy What a healthy CAC-to-CLV ratio looks like and how it impacts sustainable growth How payback period shapes cash flow, investment decisions, and scaling strategy Practical ways PMs can influence these metrics through smarter acquisition, retention, and product design

If you’ve ever wanted to connect product decisions to the bigger business picture — or speak the same language as investors and execs — this episode gives you the financial foundations to do it with confidence.
