# Question: The weighted average cost of capital WACC is the weighted

The weighted average cost of capital (WACC) is the weighted average after-tax cost of an organization’s various sources of financing such as debt and stock. In this chapter, we learned that the WACC is used when calculating economic value added. The WACC is also used in capital budgeting (Chapter 12).
Calculations for the weighted average cost of capital are usually found in finance textbooks. The formula is simple; we determine how much financing comes from various sources, and then calculate the weighted average. For example, suppose a company has \$600,000 financing from debt at a pretax interest rate of 7% and \$400,000 financing from equity having a cost of 9%. The company’s tax rate is 30%, and only the interest is tax deductible. The WACC is 6.54%, calculated as follows:

Although the computations are simple, it is not always easy to find the information needed for the computations. For example, consider the following balance sheet for Amazon.com as of December 31, 2002 (amounts in \$ thousands):
