Determine your Weighted Average Cost of Capital (WACC) to accurately discount future cash flows and evaluate investment opportunities.
Your complete guide to calculating and interpreting WACC.
The Weighted Average Cost of Capital (WACC) represents a firm's average after-tax cost of capital from all sources, including common stock, preferred stock, bonds, and other forms of debt. WACC is a common calculation referenced by investors to determine the minimum acceptable rate of return on an investment.
WACC serves as the discount rate when performing a Discounted Cash Flow (DCF) analysis. A lower WACC indicates a cheaper cost of financing and results in a higher present value of future cash flows, leading to a higher company valuation. It essentially functions as the "hurdle rate" that a company must overcome to produce profit.
The calculation weights each capital component according to its proportion of total capital:
WACC = (E/V × Re) + [D/V × Rd × (1 – T)]
Notice the "(1 - T)" term on the cost of debt. This calculates the tax shield created by interest expenses, which makes debt financing cheaper than equity financing up to a certain point.
