Frequently Asked Questions
What is the WACC formula?
WACC = (E / (E+D)) x Cost of Equity + (D / (E+D)) x Cost of Debt x (1 - Tax Rate), where E is the market value of equity and D is the market value of debt.
Why does the cost of debt get multiplied by (1 - Tax Rate)?
Interest payments on debt are typically tax-deductible, which lowers the effective after-tax cost of debt financing. WACC accounts for that tax shield.
