In this video, I walk you through a numerical example in Excel that shows how you can use the WACC approach to calculate Enterprise Value of a firm. This approach (and example) is useful in helping you understand how an acquiring firm can value a target firm (i.e. a firm they are considering buying) and to calculate the maximum they should pay for the target firm on a per share basis.
