Definition of Optimal Capital Structure

  • The optimal capital structure of a firm is the right combination of equity and debt financing.
  • It allows the firm to have a minimum cost of capital while having the maximum market value.
  • The lesser the cost of capital, the more the market value of the company.
  • Debt financing may have the lowest cost, but having too much of it would increase risks to the shareholders.
  • So, firms need to find a balance between both to benefit from it entirely.
