Divisional Cost of Capital

When a firm has more than one division (line of business), the cost of capital of each division will be different based on the risk of the business. The business with lower risk will have a lower cost of capital, whereas the one with a higher risk will have a higher cost of capital.The overall cost of capital will be the weighted average of the cost of capital for each division.

Answer and Explanation:

  • Overall cost of capital can be calculated as follows:

Division MV of assets Weights Cost of capital Weights * cost
Infra 250,000,000 0.20 8.75 1.75
Power 325,000,000 0.26 7.50 1.95
Telecom 675,000,000 0.54 8.25 4.455
Total 1250,000,000 1 8.155

  • The weights assigned will be based on the market value of business.For example, the weight assigned for infrastructure division = 250,000,000 / 1250,000,000 = 0.20

The total of weights will be equal to 1

  • The sum of the last column (weights * cost) will be the overall cost of capital

The overall cost of capital for the company is 8.155 or 8.16%
