Also, a net benefit to the company’s balance sheets results if the return on investment is greater than the cost of capital in investing. However, not spending money wisely affects investment returns that are equal to or lower than the cost of capital.

Types of Cost of Capital in Financial Management

A specific cost is one of the types of costs of capital in financial management from a particular source. As an example, all these typical short-term sources, such as bank credit, trade credit, and bills, are temporary in nature and are subject to payback in the short term. Moreover, having specific costs such as long-term sources includes 

  • loan and long-term debt.
  • Capital preference shares
  • Investing in equity shares
  • The company holds profits.

Furthermore, the use of capital funds should also take into account a company’s overall cost of capital. As a result, the overall cost of capital is a key factor in the capital budgeting evaluation process. 

#2. Explicit and Implicit Cost of Capital

In a capitalist type of financial firm, analyzing the cost of capital in financial management can be explicit or implicit. 

The cost is a charge for the use of factors of production like land, labor, capital, and so on. They are in the form of rent, salary, materials, wages, and other costs like electricity, stationery, postage, etc.

Weighted Average Cost of Capital in Financial Management

The weighted average cost of capital in financial management determines the overall cost of capital while combining debt and equity to finance business growth.  

In addition, calculating a firm’s cost of capital generally involves using a weighted average price of capital formula that considers the cost of both debt and equity capital.

Calculating the Weighted Average Cost of Capital

Calculating the weighted average cost of capital involves multiplying the cost of each type of capital by the percentage of that type of capital on the balance sheet of the company and adding the products together. 

The weighted average cost of capital in financial management (WACC) assists investors in determining the risk of cash flows and the value of company shares, projects, and potential acquisitions. Furthermore, it determines the discount rate for future cash flows in order to determine the value of a business.

Calculating WACC is by multiplying the cost of each capital source (equity and debt) by its proper weight at market value, then adding the results to get the total. The formula is:

WACC = (E/V x Re) + ((D/V x Rd) x (1 – T))

The following is a breakdown of the parts of this formula:

  • E stands for the market value of a company’s equity.
  • D: The market value of a company’s debt.
  • V: Total capital value (equity + debt)
  • E/V: The percentage of capital that is equity.
  • D/V: The debt-to-capital ratio.
  • Re: Concerning the required rate of return
  • Rd: Cost of debt
  • T: The tax rate

A high WACC calculation indicates that a company’s stock or debt is too risky, implying that investors will demand higher returns.

Cost of Capital in Financial Management Problems

Applying the firm’s cost of capital is both practical and abstract when working on a wide range of problems.

These can be briefly summarised as follows:

#1. Calculating the Equity Cost of capital

Financing equity is one of the cost of capital financial management problems. For instance, the market price of the company’s shares is generally constant. In addition, a company must earn a portion of the minimum rate of return on its capital employed. Although this is a difficult task because the equity shareholders value the equity shares based on a variety of financial and psychological considerations.

Calculating the Cost of Depreciation and Retained Earnings Funds

For this, there are various points of view and methods. For instance, providing and sharing income with shareholders as dividends would have given them some profit. Therefore, the profit that the shareholders forego is the cost of retained profits, which results in its calculation not being easy. 

#3. The Debate Over How Much the Cost of Capital Depends on the Type and Amount of Financing

Arguments against making decisions based on historical costs are needed. The cost in the future should also be taken into account. This, therefore, raises the question of whether to take the marginal cost of capital into account.

#4. Comparison of current and future costs

Many assert that the debt-to-equity ratio change has no impact on the overall cost of capital. Whether or not the cost of capital problems in financial management depends on the type and amount of capital provided by the company, is a challenge.

#5. The weights issue

It can be difficult to assign weights to different fund types. As a result, it can be difficult to choose between the market value of each source of funding and its risk value.


It is necessary to look at the cost of the company’s capital structure as a whole because the majority of businesses use multiple sources of capital funds to finance their capital budgeting proposals and because the combination of these sources may change over time. The company must have a weighted capital cost that accounts for the variations among the different sources of capital used.
