Summary

A firm can use debt to finance its operations and investments. Debt can create valuable tax savings, but it also requires scheduled interest and principal payments. This lesson explains why additional borrowing can increase the risk and cost of financial distress, and how those effects shape a firm’s financing choices.

When a company borrows, interest payments are generally deductible when calculating taxable income. This deduction creates an interest tax shield: the firm pays less tax than it would if it had no interest expense, all else equal. Increasing debt can increase the value of this benefit.

Quiz questions

  1. In capital structure decisions, what makes a debt level optimal?Answer: It maximizes firm value after accounting for debt's benefits and costs.
  2. In the simplified WACC formula, what represents the after-tax cost of debt? Here, wDw_D is the debt weight, rDr_D is the before-tax cost of debt, and TcT_c is the corporate tax rate.Answer: wDrD(1−Tc)w_D r_D(1-T_c)
  3. How are debt and equity weights for a target capital structure generally determined?Answer: From the market values of debt and equity.
  4. Why might a firm leave a small deviation from its target debt weight uncorrected?Answer: The transaction costs of adjusting the mix may exceed the benefit of a closer match.
