Frequently Asked Questions
What is WACC?
WACC (Weighted Average Cost of Capital) is the average rate a company expects to pay to finance its assets. It represents the minimum return a company must earn to satisfy all its investors.
How is WACC calculated?
WACC = (E/V × Re) + (D/V × Rd × (1-T)), where E is equity value, D is debt value, V is total value, Re is cost of equity, Rd is cost of debt, and T is tax rate.
Why is WACC important?
WACC is used as the discount rate in NPV calculations, helps evaluate investment opportunities, and serves as a hurdle rate for capital budgeting decisions.
What is a good WACC?
A lower WACC is generally better as it means cheaper financing. Typical WACC ranges from 5-15% depending on industry risk. Compare against your industry average.
How does debt affect WACC?
Debt is usually cheaper than equity and provides a tax shield (interest is tax-deductible). However, too much debt increases financial risk and can raise both cost of debt and equity.
