Unit 5: Cost of Capital

My estimate of Nike's cost of equity is 10.5 per cent I used the current yield on 20-year Notes
Treasury bonds as my risk-free rate, and the compound average premium of the market
over Treasury bonds (5.9 per cent) as my risk premium. For beta, I took the average of
Nike's beta from 1996 to the present.
Putting it all Together
After inputting all my assumptions into the WACC formula, my estimate of Nike's cost of
capital is 8.4 per cent.
WACC = K (1 - t) × D/(D + E) + K × E/(D + E)
d c
= 2.7% × 27.0% + 20.5% × 73.0%
= 8.4%

Question
What is the importance of cost of capital for any firm?

not putting his funds elsewhere.

 Cost of equity capital, is the minimum rate of return that a firm must earn on the equity
financed portions of an investment project in order to leave unchanged the market price of
the shares.
 The marginal cost of capital is the weighted average cost of new capital using the marginal
weights.

 Marginal cost of capital shall be equal to WACC, when a firm employs the existing
proportion of capital structure and some cost of component of capital structure.
