In relation to WACC, why might a firm prefer debt over equity?

A firm might prefer debt over equity primarily due to the tax advantages that come with debt financing. Interest payments on debt are typically tax-deductible, which means that the effective cost of borrowing is lower than it might appear at first glance. This tax shield effectively reduces the company's taxable income, thus lowering its overall tax burden. Since WACC (Weighted Average Cost of Capital) is calculated using the cost of equity and the after-tax cost of debt, a lower cost of debt can ultimately reduce the WACC, making the firm more attractive to investors and increasing its value.

When firms use debt financing, they are able to capitalize on these tax benefits, which can lead to a lower overall cost of capital compared to relying solely on equity financing. This can also allow the firm to take on more investments that may be beneficial for growth, as the cost of financing remains relatively lower due to tax deductions.

Another aspect is the potential for higher returns on equity since the cost of equity financing tends to be higher than that of debt. When companies leverage their operations with debt, they can magnify the returns to equity holders when the investments financed through debt yield higher returns than the cost of that debt. However, this introduces risk, as too much leverage can lead to
