What is the Weighted Average Cost of Capital (WACC) and Why It Matters

The Weighted Average Cost of Capital (WACC) is a vital financial metric that measures the average cost a company incurs to finance its assets through a blend of equity and debt financing. It effectively captures the company’s required return from both shareholders and creditors, weighted by their respective contributions to the company’s capital structure.

Understanding WACC is essential because it:

• Helps evaluate new investment opportunities and capital projects
• Determines the minimum acceptable return for shareholders and lenders
• Guides strategic decisions on financing and capital structure optimization
• Serves as the discount rate in company valuation models

By calculating WACC, businesses ensure their investments generate returns above their overall cost of capital, creating value for shareholders.

The Weighted Average Cost of Capital Formula Explained

The formula for calculating WACC is:

$$ WACC = \frac{E}{V} \times R_e + \frac{D}{V} \times R_d \times (1 – T_c) $$

Where:

• E = Market value of the company’s equity
• D = Market value of the company’s debt
• V = Total market value of financing, V = E + D
• R_e = Cost of equity (expressed as a decimal)
• R_d = Cost of debt (expressed as a decimal)
• T_c = Corporate tax rate (expressed as a decimal)

Example Calculation Using the WACC Calculator

Suppose a company has the following financial data:

• Market value of equity (E): $750 million
• Market value of debt (D): $350 million
• Cost of equity (R_e): 10.5%
• Cost of debt (R_d): 6.2%
• Corporate tax rate (T_c): 28%

First, calculate the total value of the firm’s financing:

$$ V = E + D = 750,000,000 + 350,000,000 = 1,100,000,000 $$

Now, plug into the WACC formula:

$$ WACC = \frac{750,000,000}{1,100,000,000} \times 0.105 + \frac{350,000,000}{1,100,000,000} \times 0.062 \times (1 – 0.28) $$

Calculating each term:

• Equity portion: 0.6818 × 0.105 = 0.0716 (7.16%)
• Debt portion after tax: 0.3182 × 0.062 × 0.72 = 0.0142 (1.42%)

Adding both gives:

$$ WACC = 7.16\% + 1.42\% = 8.58\% $$

This means the firm’s average cost of capital is approximately 8.58%. Projects returning above this rate create shareholder value.

Before funding a new product launch or expansion, companies can calculate their WACC to set a minimum acceptable rate of return. If the projected ROI surpasses the WACC, the project is likely value-adding.

2. Making Acquisition Decisions

Investors and corporate strategists use WACC to compare acquisition targets. A lower WACC indicates a cheaper cost of capital, making companies with low WACC more attractive targets.

3. Optimizing Capital Structure

By experimenting with different proportions of equity and debt inputs, businesses can identify the optimal blend that minimizes WACC, reducing their overall cost of financing and boosting profitability.
