In this lesson, Nick Palazzolo, CPA, breaks down the concept of weighted averages and how they apply to the calculation of the Weighted Average Cost of Capital (WACC). With a relatable example involving test scores from various cities, Nick illustrates the difference between a normal average and a weighted average, setting the scene for understanding the WACC's components. He proceeds to explain the importance of WACC as a hurdle rate, detailing how it represents the average cost of financing from equity, debt, and preferred stock. Nick also clarifies how costs of these capital components are weighted and why a lower WACC is beneficial. This engaging and practical approach makes the underlying principles of WACC and its computation clear and accessible.
