How is the Weighted Average Cost of Capital (WACC) primarily calculated?

The Weighted Average Cost of Capital (WACC) is primarily calculated using a formula that reflects the proportion of equity and debt in a company’s capital structure, along with the cost associated with each component. This calculation is critical for understanding how much a company is paying on average for its financing sources, and it integrates both equity and debt weighting in its computation.

The formula involves multiplying the cost of equity by the proportion of equity in the overall capital structure, and the cost of debt by its proportion. The result is then summed to yield a comprehensive rate that effectively captures the cost of funding for the business as a whole. This weighted approach is essential because it ensures that the calculated WACC is representative of the actual capital costs, taking into account the relative sizes of equity and debt, which typically have different costs attached to them.

By contrast, other methods of calculation mentioned in the options do not capture the necessary relationship between the financing costs and the structure of the capital employed. For instance, simply dividing total revenue by assets or net income by liabilities does not provide insight into the specific costs of capital that a firm incurs, nor does it reflect the risk and different cost patterns associated with equity and debt financing.

Thus, the correct calculation method outlined in the chosen
