Calculating WACC

In corporate finance, the Weighted Average Cost of Capital (WACC) is a crucial metric used by firms to evaluate potential investment projects. WACC represents a firm's average cost of capital from all sources, including equity and debt, weighted by their respective proportions in the capital structure.

Consider a company that has a weight of 60% equity and 40% debt in its capital structure. If the cost of equity is 10% and the after-tax cost of debt is 5%, what would be the company's WACC?
