Specific Cost of Capital

Specific cost of capital refers to the cost associated with a particular source of finance used by a business. Every source of capital, such as equity shares, preference shares, debentures, retained earnings, and loans, has its own cost because investors and lenders expect a return on the funds they provide. The specific cost of capital measures the rate of return required by the providers of a particular source of finance. It helps financial managers evaluate the cost-effectiveness of different financing options and make appropriate funding decisions. Specific cost is usually expressed as a percentage and forms the basis for calculating the overall cost of capital.

Specific Cost of Capital

1. Cost of Equity Share Capital

Cost of equity share capital is the rate of return required by equity shareholders for investing in a company. Equity shareholders are the owners of the company and bear the highest risk because they receive dividends only after all other claims have been satisfied. Therefore, they expect a higher return compared to other investors. The cost of equity is important because it helps management determine the minimum return that must be earned on investments financed through equity.

Calculation

Using the Dividend Growth Model (DGM):

Ke = (D₁ / P₀) + g

Where:

• Ke = Cost of Equity
• D₁ = Expected Dividend per Share
• P₀ = Current Market Price per Share
• g = Growth Rate of Dividend

Example

Suppose a company’s share is selling at ₹100. Expected dividend next year is ₹8 per share, and dividend growth rate is 5%.

Ke = (8 / 100) + 0.05

Ke = 0.08 + 0.05 = 0.13 or 13%

This means the company must earn at least 13% on investments financed through equity capital to satisfy shareholders. If the return is lower than 13%, shareholders may consider alternative investments with better returns.

2. Cost of Preference Share Capital

Cost of preference share capital is the return required by preference shareholders. Preference shares provide a fixed dividend and have priority over equity shares in dividend payments and capital repayment. Since preference shareholders face lower risk than equity shareholders, their required return is generally lower. Preference capital is useful when a company needs long-term funds without giving additional voting rights to investors.

Calculation: Kp = D / NP

Where:

• Kp = Cost of Preference Capital
• D = Annual Preference Dividend
• NP = Net Proceeds from Preference Shares

Example

A company issues preference shares of ₹100 each carrying a 10% dividend. The company receives net proceeds of ₹95 per share after flotation expenses.

Annual Dividend = ₹100 × 10% = ₹10

Kp = 10 / 95

Kp = 0.1053 or 10.53%

The cost of preference capital is 10.53%. Therefore, projects financed through preference shares should generate returns higher than this percentage to create value for the company.

3. Cost of Debenture Capital

Cost of debenture capital represents the effective cost of borrowing through debentures. Debenture holders are creditors of the company and receive fixed interest payments. Since interest expenses are tax-deductible, the after-tax cost of debentures is lower than the stated interest rate. This tax benefit makes debentures a relatively cheaper source of finance.

Calculation: Kd = I (1 − T) / NP

Where:

• Kd = Cost of Debenture
• I = Annual Interest
• T = Tax Rate
• NP = Net Proceeds

Example

A company issues debentures worth ₹1,000 carrying 12% interest. Net proceeds are ₹980. Corporate tax rate is 30%.

Interest = ₹1,000 × 12% = ₹120

After-tax Interest = ₹120 × (1 − 0.30)

= ₹84

Kd = 84 / 980

Kd = 0.0857 or 8.57%

Although the nominal interest rate is 12%, the effective after-tax cost is only 8.57%, making debenture financing economical.

4. Cost of Term Loans

Term loans are funds borrowed from banks and financial institutions for a fixed period. Companies use term loans to finance machinery, buildings, equipment, and expansion projects. Since interest on loans is tax-deductible, the after-tax cost is lower than the stated interest rate.

Calculation: Kt = Interest Rate × (1 − Tax Rate)

Example

A company obtains a bank loan of ₹10,00,000 at an interest rate of 11%. Corporate tax rate is 30%.

Kt = 11% × (1 − 0.30)

Kt = 11% × 0.70

Kt = 7.7%

The effective cost of the loan is 7.7%. This means that after considering tax savings, the company effectively pays only 7.7% for using the borrowed funds. Management compares this cost with other financing alternatives before selecting the best source of capital.

5. Cost of Retained Earnings

Retained earnings are profits kept within the business rather than distributed to shareholders. Although retained earnings do not involve direct payments, they have an opportunity cost because shareholders could have invested those profits elsewhere. Therefore, retained earnings are not considered free funds.

Calculation

Generally:

Kr = Cost of Equity Capital

Example

Assume shareholders expect a return of 14% on their investments. Instead of paying dividends, the company retains profits for expansion.

Cost of Retained Earnings:

Kr = 14%

This means the company must earn at least 14% on projects financed through retained earnings. If the project earns only 10%, shareholders lose potential returns they could have earned elsewhere. Therefore, retained earnings carry a real economic cost despite involving no direct cash payment.

6. Cost of Convertible Securities

Convertible securities include convertible debentures and convertible preference shares that can later be converted into equity shares. These securities provide fixed returns initially and allow investors to participate in future growth through conversion. Because of this additional benefit, investors generally accept lower initial returns.

Calculation: The cost is determined by considering both current payments and conversion value.

Example

A company issues convertible debentures of ₹1,000 with 8% interest. After five years, each debenture can be converted into equity shares worth ₹1,200.

Annual Interest = ₹1,000 × 8%

= ₹80

Investors receive ₹80 annually and gain additional value through conversion. As a result, they may accept a lower interest rate than ordinary debenture holders. The effective cost to the company may be lower than issuing pure equity shares because investors are compensated through future ownership opportunities rather than higher current returns.

7. Importance of Specific Cost of Capital

Specific cost of capital helps financial managers understand the exact cost associated with each source of finance. Different sources have different risk levels, costs, and benefits. By calculating specific costs, companies can choose the most economical financing option and improve profitability.

Example

Suppose a company has the following costs:

• Equity Capital = 15%
• Preference Capital = 11%
• Debenture Capital = 8%
• Term Loan = 7.5%

Management can observe that debt financing is cheaper than equity financing. However, excessive debt may increase financial risk. Therefore, the company uses specific cost information to balance cost and risk while designing an optimal capital structure. This helps maximize shareholder wealth and minimize overall financing expenses.

8. Role in Financial Decision-Making

Specific cost of capital plays a vital role in investment appraisal, financing decisions, business valuation, and capital structure planning. It serves as a benchmark for evaluating projects and determining whether expected returns justify the cost of funds.

Example

A company is evaluating a project requiring ₹20 lakh financed through debentures with a specific cost of 9%.

Expected Project Return = 14%

Cost of Debenture Capital = 9%

Net Gain = 14% − 9% = 5%

Since the project’s return exceeds the cost of financing, the investment is financially acceptable. If the return were below 9%, the project would reduce shareholder value. Thus, specific cost of capital helps managers make rational decisions, allocate resources efficiently, and ensure that investments contribute positively to the company’s long-term growth and profitability.
