Each type of capital used by the firm (debt, preference shares and equity) should be incorporated into the cost of capital, with the relative importance of a particular source being based on the percentage of the financing provided by each source of capital.
Using of the cost a single source of capital as the hurdle rate is tempting to management, particularly when an investment is financed entirely by debt. However, doing so is a mistake in logic and can cause problems.
Cost of Capital Definition
‘Cost of Capital’ is a concept having manifold meanings. Cost of capital, for an investor is the measurement of disutility of funds in the present as compared to the return expected in the future. From the firm’s point of view, its meaning is somewhat different.

Classification of Cost of Capital
- Historical Cost and Future Cost
- Specific Cost and Composite Cost
- Average Cost and Marginal Cost
- Explicit Cost and Implicit Cost
Historical Cost and Future Cost
Historical cost are those which are calculated on the basis of existing capital structure. Future cost relates to the cost of funds intended to finance the expected project, historical costs are useful for analyzing the existing capital structures.
Future costs are widely used in capital budgeting and capital structure designing decisions.
Specific Cost and Composite Cost
The cost of individual source of capital is referred to as the specific cost and the cost of capital of all the sources combined is termed as composite cost. It is, thus the weighted cost of capital.
Average Cost and Marginal Cost
The average cost is the average of the various specific costs of the different components of capital structure at a given time. The average cost is relevant for overall investment decision as on enterprise employs a mix of different sources.
The marginal cost of capital is that average cost which is concerned with the additional funds raised by the firm. It is very important in capital budgeting decisions. Marginal cost tends to increase proportionately as the amount of debt increases.
Explicit Cost and Implicit Cost
An explicit cost is the discount rate which equates the present value of cash inflows with the present value of cash outflows. In other words, it is the internal rate of return of cash flows.
Implicit cost is also known as opportunity cost. It may be defined as the rate of return associated with the best investment opportunity for the firm. It is generally said that cost of retained earnings is an opportunity cost in the sense that it is the rate of return at which the shareholders could have invested these funds had they been distributed among them.

Problems in Determining Cost of Capital
The determination of cost of capital is not an easy task. The financial manager is confronted with a large number of problems.
These problems can briefly be summarized as follows:
- Conceptual Controversy
- Computation of Cost of Equity
- Determination of Cost of Retained Earnings
- Future Cost Versus Historical Cost
- Problems of Weight
There is major controversy whether or not the cost of capital is dependent upon the method and level of financing by the company.
According to traditional theorists, a firm can change its overall cost of capital by changing debt-equity mix. On the other hand, the modern theorists, reject the traditional view and holds that cost of capital is independent of the method and level of financing.
Computation of Cost of Equity
Determination of cost of equity is a difficult task because the equity shareholders value the equity shares of company on the basis of a large number of factors, financial as well as psychological.
Determination of Cost of Retained Earnings
The cost of retained earnings is determined according to the approach adopted for computing the cost of equity shares which is it self a controversial problem.
Future Cost Versus Historical Cost
It is argued that for decision making purposes, the historical cost is not relevant. The future cost should be considered. It, therefore, creates another problem whether to consider marginal cost of capital or average cost of capital.
Problems of Weight
The assignment of weights to each type of funds is a complex. The finance manager has to make a choise between the book value to each source of funds and the market value of each source of funds. The result would be different in each case.
