What is the cost of capital and how is it used as the discount rate?

Advanced

Answer

The cost of capital is the return required by the providers of finance (debt and equity), often measured as the weighted average cost of capital (WACC). It's used as the discount rate/hurdle rate in NPV and the benchmark for IRR because a project must earn at least this return to satisfy investors and add value.
WACC = (E/V)xKe + (D/V)xKd(1-tax).
Real-world example The firm discounts project cash flows at its 9% WACC and rejects projects returning less.
