Weighted Average Cost of Capital Instructor: Williams
Weighted Average Cost of Capital • Also abbreviated “WACC” • Don’t get thrown by the jargon! • Remember! • Cost of Debt Capital = Required Rate of Return on Debt • Cost of Equity Capital = Required Rate of Return on Equity/Stock • Think waaaaaaaaaaaay back…what are the sources of financing?
Financing and WAAC • Financing is with debt & equity. • If we know “r” for debt, and “r” for equity, what should be our “r” for capital budgeting? • Alternatively, we know our cost of debt and our cost of equity, what is our cost of CAPITAL?
It is just the weighted average of the two. • We need some sort of weighting! • What about this one?: • (weight of equity) * cost of equity+ (1-weight of equity) * cost of debt • Think back to day #1 => there is a tax break to debt. • So we have to discount debt by the tax rate. • How?
WACC • WACC = (weight of equity) * R equity + (1-weight of equity) * (1-Tax rate)*R debt
BIG assumption - Important • KNOW THIS! • In this class, we treat WACC for firm as WACC for capital budgeting project. • This is to keep problems simple. • THIS IS ONLY TRUE IF NEW PROJECT IS EXACTLY LIKE THE REST OF THE COMPANY! • Usually not true.
Simple Example • The CFO estimates that the cost of debt is 4% and the cost of equity is 11%. The market cap of the entire firm is $500 million, the market cap of equity is $300 million. • What is the cost of capital?
Complicated Example • You are advising the CFO of Jupiter Motors. She wants to know her cost of capital. You observe the following information: • You have 1 million bonds outstanding. The bonds have a face value of $1000 and a coupon rate of 8%. The bonds are currently trading at $894. • Your stock’s beta is 1.2, the market return is 9% and the risk free rate is 3%. You have 2 million shares outstanding. Your shareholders expect dividend growth of 1% and you paid a dividend of $3 yesterday. • Your tax rate is 35%. • What is the cost of capital?
