As more capital is raised, the marginal cost of capital rises. With the weights and costs given in our previous example, we computed Newco's weighted average cost of capital as follows:

      • WACC = (wd)(kd)(1-t) + (wps)(kps) + (wce)(kce)
      • WACC = (0.4)(0.07)(1-0.4) + (0.05)(0.021) + (0.55)(0.12)
      • WACC = 0.084, or 8.4%
    • We originally determined the WACC for Newco to be 8.4%. Newco's cost of capital will remain unchanged as new debt, preferred stock and retained earnings are issued until the company's retained earnings are depleted.
