In order to estimate correct required rate, companies must find their own unique cost of raising capital

Factors Affecting Cost of Capital
• General Economic Conditions--inflation, investment opportunities
• Affect interest rates
• The Following Factors affect risk premium
• Market Conditions
• Operating and Financing Decisions
• Affect financial risk
• Amount of Financing
• Affect flotation costs and market price of security
Model Assumptions

Weighted Average Cost of Capital Model

• Here, we determine the average cost of capital of a firm by assuming that the firm continues with its business, financing and dividend policies.
Computing Weighted Cost of Capital

Weighted Average Cost of Capital (WACC)

• Average cost of capital of the firm.
• To find WACC
• 1. Compute the cost of each source of capital
• 2. Determine percentage of each source of capital
• 3. Calculate Weighted Average Cost of Capital
Computing Cost of Each Source

1. Compute Cost of Debt

• Required rate of return for creditors
• Same cost found in Chapter 7 as “required rate for debtholders (kd) = YTM”

1. Compute Cost of Debt

• Example

Investors are willing to pay \$985 for a bond that pays \$90 a year for 10 years. Fees for issuing the bonds bring the net price (NP0) down to \$938.55. What is the before tax cost of debt?

Capital Structure Weights

Long Term Liabilities and Equity

Weights of each source should reflect expected financing mix

Assume a stable financial mix–so use Balance Sheet percentages to calculate the weighted average cost of capital.

Weighted Marginal Cost of Capital
• A firm’s cost of capital will change as it is raises more and more capital
• Retained earnings will be used up at some level
• The cost of other sources may rise beyond a certain amount of money has been raised
Weighted Marginal Cost of Capital
• A firm’s cost of capital will changes as it is raising more and more capital
• Retained earnings will be used up at some level
• The cost of other sources may rise beyond a certain amount of money raised
• Therefore, beyond a point, the WACC will rise.
• Calculate the point at which the cost of capital increases
