The Logic of the Weighted Average Cost of Capital = WACC

The use of debt impacts the ability to use equity, and vice versa.

The weighted average cost must be used to evaluate projects, regardless of the specific financing used to fund a particular project.

Basic Definitions

WACC Weighted Average Cost of Capital

Capital StructureA combination of different types of capital (debt and equity) used by a firm

Page 7: Chapter 8 The Cost of Capital © 2005 Thomson/South-Western

After-Tax Cost of DebtThe relevant cost of new debtTakes into account the tax deductibility of interestUsed to calculate the WACC

kdT = bondholders’ required rate of return minus tax savings

kdT = kd - (kd x T) = kd(1-T)

The Discounted Cash Flow Approach

Price and expected rate of return on a share of common stock depend on the dividends expected on the stock.
