The cost of capital is a vital element in the capital budgeting process.
For a project to be accepted, it must provide
a return that exceeds its cost of capital, or hurdle rate.
The cost of capital also serves three other purposes: (1) It is
used to help determine the EVA, (2) Managers use the cost of capital when deciding between buying and leasing,
and (3) the cost of capital is used in the regulation of electric, gas, and telephone companies.
The cost of capital is the weighted average cost of the debt, preferred stock, and common equity that the firm uses
to finance its assets, or its WACC. There is an overall, or corporate, WACC which reflects the average riskiness of
all the firm's assets.
However, since different assets may have more or less risk than the average, the overall
WACC must be adjusted up or down to reflect the riskiness of different proposed capital budgeting projects.
