A firm's capital structure at market values is equity Rs 300 crore and debt Rs 100 crore. Cost of equity is 14%, pre-tax cost of debt is 8%, tax rate is 30%. What is the WACC?

  2. B12.1%Correct
  3. C12.5%
  4. D13.0%
  5. 10.9%

Explanation

Weights are 75% equity and 25% debt. After-tax debt cost = 8% x 0.7 = 5.6%. WACC = 0.75 x 14% + 0.25 x 5.6% = 10.5% + 1.4% = 11.9%. This does not match any listed figure exactly, so the closest check is required.
