What is an 'Optimal Capital Structure'
An optimal capital structure is the best debttoequity ratio for a firm that maximizes its value. The optimal capital structure for a company is one which offers a balance between the ideal debttoequity range and minimizes the firm's cost of capital. In theory, debt financing generally offers the lowest cost of capital due to its tax deductibility. However, it is rarely the optimal structure since a company's risk generally increases as debt increases.
BREAKING DOWN 'Optimal Capital Structure'
A company's ratio of short and longterm debt should also be considered when examining its capital structure. Capital structure is most often referred to as a firm's debttoequity ratio, which provides insight into how risky a company is for potential investors. Determining an optimal capital is a chief requirement of any firm's corporate finance department.
