COST OF CAPITAL
Cost of capital is a decisive factor in financial
decision-making. W measure and compare the cost of capital in deciding the
capital structure of the company so as to earn a fair return to the owner an at
least a fair return to the contributors. In recent years, it has received a
considerable attention from both theorists and practitioners. Two major schools
of thought have emerged having basic differences on the relevance of the
concepts but both concepts are based on optimal policy. One school of thought
is of the opinion that the cost of capital of a firm is constant and it is
quite independent of the method and the level of financing. If we follow this
concept, it means that financial planning is no problem. Under thus concept, optimal
policy is the investment that equates the marginal return on investment with
tis cost of capital. The opposite view is that cost of capital is not constant
and varies with the method and level of financing.
Importance of Cost of
Capital in Decision Making
The concept of cost of capital is a very important concept
in financial management decision making. The concept, is however, a recent
development and has relevance in almost every financial decision making but
prior to that development, the problem was ignored or by-passed.
The progressive management always takes notice of the cost
of capital while taking a financial decision. The concept is quite relevant in
the following managerial decisions.
(1) Capital Budgeting Decision. Cost of capital may be used as the measuring road for adopting an investment proposal. The firm, naturally, will choose the project which gives a satisfactory return on investment which would in no case be less than the cost of capital incurred for its financing. In various methods of capital budgeting, cost of capital is the key factor in deciding the project out of various proposals pending before the management. It measures the financial performance and determines the acceptability of all investment opportunities.
(2) Designing the Corporate Financial Structure. The cost of capital is significant in designing the firm's capital structure. The cost of capital is influenced by the chances in capital structure. A capable financial executive always keeps an eye on capital market fluctuations and tries to achieve the sound and economical capital structure for the firm. He may try to substitute the various methods of finance in an attempt to minimise the cost of capital so as to increase the market price and the earning per share.
(3) Deciding about the Method of Financing. A capable financial executive must have knowledge of the fluctuations in the capital market and should analyse the rate of interest on loans and normal dividend rates in the market from time to time. Whenever company requires additional finance, he may ave a better choice of the source of finance which bears the minimum cost of capital. Although cost of capital is an important factor in such decisions, but equally important are the considerations of relating control and of avoiding risk.
(4) Performance of Top Management. The cost of capital can be used to evaluate the financial performance of the top executives. Evaluation of the financial performance will involve a comparison of actual profitabilities of the projects and taken with the projected overall cost of capital and an appraisal of the actual cost incurred in raising the required funds.
(5) Other Areas. The concept of cost of capital is also important in many others areas of decision making, such as dividend decisions, working capital policy etc.

Relevant Costs
The following costs are relevant costs, closely associated
with the problem of cost of capital
(1) Marginal Cost of
Capital or Explicit Cost. The current rate of interest on long term debts
or current rate of return is treated as the marginal cost of capital. Marginal
cost or explicit cost tends to increase proportionately as the amount of debt
increases.
(2) Implicit Cost or Real Cost. The explicit cost includes only the cost of capital to be paid and ignores the other factors such as risks involved, flexibility and leverage. Characteristics which are adversely affected with an increase in debt contents in its capital costs may be determined by taking these factors into consideration. The real cost of raising debt is, therefore, a substantially higher than explicit cost.
(3) Future Cost and Historical Cost. For decision making purposes, future costs are relevant and the financial decision making is no exception. We always consider the projects, expected internal rate of return and compare it with the expected (future) cost of capital while making capital expenditure decision. Similarly, we plan to minimise the future cost of capital at the time of designing a capital structure-cost incurred in the past (Historical cost) cannot be minimized. Historical costs help in predicting the future costs and provide an evaluation of the past performance when compared with standard costs.
(4) Specific Cost and Inclusive Cost or Average Cost. Specific cost, of capital is associated with a specific component of capital structure, e.g., cost of debentures, cost of preference shares etc. In affiancing decisions involving alternatives which may not affect the capital structure (Selection of two alternative debentures of similar size) specific cost should be used as the criterion for decision making. Inclusive cost or average of various specific cost of different components of various sources at a given time. This cost is relevant in investment decisions of the funds of the firm were firm employs a mix of various sources.
(5) Spot Costs and Normalized Costs. Spot costs represent those costs prevailing in the market at a certain time. This cost is considered in financing decisions involving alternative appraisal. Normalized costs indicate an estimate of cost by some averaging process from which cyclical element is removed. These are normally used in taking investment decisions.
(6) Opportunity Costs. The opportunity cost is the rate of return the shareholder forgoes by not putting the funds elsewhere. Keeping in mind the shareholders interest, this cost is used while making the investment decisions to determine the cut-off point of the project.
(2) Implicit Cost or Real Cost. The explicit cost includes only the cost of capital to be paid and ignores the other factors such as risks involved, flexibility and leverage. Characteristics which are adversely affected with an increase in debt contents in its capital costs may be determined by taking these factors into consideration. The real cost of raising debt is, therefore, a substantially higher than explicit cost.

We always consider the projects, expected internal rate of return and compare it with the expected (future) cost of capital while making capital expenditure decision. Similarly, we plan to minimise the future cost of capital at the time of designing a capital structure-cost incurred in the past (Historical cost) cannot be minimized. Historical costs help in predicting the future costs and provide an evaluation of the past performance when compared with standard costs.

(6) Opportunity Costs. The opportunity cost is the rate of return the shareholder forgoes by not putting the funds elsewhere. Keeping in mind the shareholders interest, this cost is used while making the investment decisions to determine the cut-off point of the project.
(7) Combined Cost. The
combined or composite cost of capital is an aggregate of the cost of capital
from all sources, i.e., debt, equity and preference capital. In other words, it
is weighted cost of capital. This is relevant in capital expenditure decisions
as an acceptance criterion. It is the overall mix of financing over time which
is important in valuing firm as an ongoing overall entity.
Mode of Measuring
Cost of Capital
In making investment
decisions, cost of different types of capital is measured and compared. The
source, which is the cheapest, is chosen and capital is raised.
Now the problem is how to measure
the cost of different sources of capital. In fact, there is no exact procedure
for measuring the cost of capital. It is based largely on forecasts and is
subject to various margins of error. While computing the cost of capital care
should be taken about such factors as the needs of the company, the conditions
under which it is raising its capital, corporate policy constraints and level
of expectation. In fact, a company raises funds from different sources, and
therefore, composite cost of capital can be determined after specific cost of
each type of fund has been obtained. It is therefore, necessary to determine
the specific cost of ea source in order to determine the minimum obligation of
a company, i.e., composite cost of raising capital.
In order to determine the composite cost of capital, the specific costs of different sources of raising funds are calculated in the following manner:-
(1) Cost of Debt. In measuring cost of capital, the cost of debt should be considered first. In calculating cost of debt, contractual cost as well as imputed cost should be considered. Generally, the cost of debt (Debentures and long-term debts) is defined in terms of the required rate of return that the debt-investment must yield to protect the share holders' interest. Hence cost of debt is the contractual interest rate adjusted further for the tax-liability of the firm. As per Formula:-
Kd = (1 – T) R.

Hence cost of debt is the contractual interest rate adjusted further for the tax-liability of the firm. As per Formula:-
Kd = (1 – T) R.
Here:
Kd = Cost of debt capital
T = Marginal tax rate applicable to the company.
R = Contractual interest rate.
Suppose, a company issues 9 % debentures. Its marginal tax rate is 50 %. The effective cost of these debentures will be as follows :-
K = (1- 50) X 9
Suppose, a company issues 9 % debentures. Its marginal tax rate is 50 %. The effective cost of these debentures will be as follows :-
K = (1- 50) X 9
or
K = .50 X 9 = 4.50 %
As because of the tax deductibility
of interest, it is customary to compute the cost of borrowed funds as an after
tax-rate of interest.
When more debt finance is used, the
cost of debt is likely to increase above the actual rate of interest on account
of two accounts- (a) The contractual rate of interest will rise; and (b) hidden
cost of borrowing will also be taken into account. In this way, real cost of
debt will be higher, if company relies more and more on debt finance. If it
were not so, the management would always finance by this source of capital.
(2) Cost of Preference Shares. Preference shares are the fixed cost bearing securities. The rate of dividend is fixed well in advance at the time of their issue. So, the cost of capital of preference shares is equal to the ratio of annual dividend income per shares to the net proceed. The ratio is called current dividend yield. The formula for calculating the cost of preference share is:-

Here:
Kp = Cost of preferred capital
R = Rate of preferred dividend.
P = Net Proceeds.
For example, suppose a company
issues 95 preference shares of Rs. 100 each at a premium of Rs. 5 per share.
The issue expenses per share comes to Rs. 3 . The cost of preference capital
shall be calculated as under :-
9
9
Kp = ------------- or ------- = 8.82 %
100 + 5 – 3 102
Kp = ------------- or ------- = 8.82 %
100 + 5 – 3 102
The cost of preference share capital
is not be adjusted for taxes, because dividend on preference capital is paid
after taxes as it is not tax deductible. Thus, the cost of preference capital
is substantially greater than the cost of debt.
(3) Cost of Equity Shares. The calculation of equity capital cost is not an easy job
and raises a host of problems. Its purpose is to enable the management to make
decisions in the best interest of the equity holders. Generally the cost of
equity capital indicated the minimum rate which must be earned on projects before
their acceptance and the raising of equity funds to finance those projects
several models have been proposed. Most not-able among them are the models of
Ezra Solomon, Myren J. Gordon, James E. Walter, and the team of Modigliani and
Miller.
Here are four approaches for estimating cost of equity capital.
(A) D/P Ratio or Dividend /Price Ratio. The approach is based on the thinking that what the investors expect when they put in their savings in the company. It means that the investor arrives at the market price for a share by capitalizing the expected dividend at a normal rate of return. Through this approach is simple, but it suffers from two serious weaknesses- (a) It ignores the earnings on company's retained earnings which increases the rate of dividend in equity shares and (b) it ignores the fact that price rise of shares may be due to the retained earnings also and not on account of only high rate of dividend.
(B) Earnings Price (E/P) Ratio Approach. The E/P ratio assumes tat shareholders capitalize a stream of uncharged earnings by the capitalisation rate of earnings/price ratio in order to evaluate their holdings. The advocates of this approach, however, differ on the earnings figure and market price. Some use the current earnings and current market price for determining the capitalisation rate while others recommend average earnings and average market price over some period in the past. This approach also has three main limitations:- (i) all earnings are not distributed among the shareholders in the form of dividend, (ii) earnings per share cannot be assumed to be constant as this approach emphasizes, and (iii) share price does not remain constant because investments in retained earnings result in increase in market price of share.
(C) Dividend/Price + Growth Rate of Earning (D/P + g) Approach. This approach emphasizes what the investor actually receives, i.e., dividend + the rate of growth (g) in dividend. The growth rate in dividend is assumed to be equal to the growth rate in earnings per share. In other words, if the earnings per share increased at a rate of 5 %, of the dividend per share and market price per share should also be increased at a rate of 5 %. This approach is considered to be the best conceptual measure of the cost of new capital that ensures the optimum capital budgeting decisions. It is claimed that it will give an accurate estimate of return which the shareholders will actually realize only if the future price-earnings ratio and the current price-earnings ratio are the same and the dividend and the earnings grow at the same rate. It may be noted that removal of these assumptions will affect the validity of the approach. The main difficulty in this approach is to determine the rate of growth of price appreciation expected by a shareholder when he is willing to pay a certain price for a current dividend.
(D) Realized Yield Approach. In case where future dividend and the sale price are uncertain, it is very difficult to estimate the rate of return on investment. In order to remove this difficulty, it is suggested the cost of capital. Under this approach, the Realized yield is discounted at the present value factor and then compared with the value of investment. For example, suppose an investor purchased one share of ABC Ltd. at Rs. 240/- on January 1, 1970 and after holding it for 5 years, sold the share at Rs. 300. During this period of five years, he received a dividend of Rs. 14, Rs. 14, Rs. 14.50 and Rs. 14.50. respectively. His rate of return on discounted case flow, as computed below comes to nearly 10 %.

(A) D/P Ratio or Dividend /Price Ratio. The approach is based on the thinking that what the investors expect when they put in their savings in the company. It means that the investor arrives at the market price for a share by capitalizing the expected dividend at a normal rate of return.

Thus @ 10 % it equates initial
investment price to dividend and sale price.
The advocates of this approach suggest that the past behaviour will be materialized in future and the historic Realized rate of return would be an appropriate indicator of prospective investor's required future rate of return. We can easily remove the cyclical fluctuations in return by averaging the Realized yield and may determine the central tendency. This approach also suffers from some serious assumptions.
(4) Cost of Retained Earnings. Some regard that cost of retained earnings is nil but it is
not so. Retained earnings also have opportunity cost which can be computed
well. The opportunity cost of retained earnings in a company is the rate of
return the shareholder forgoes to determine the cut off point. Opportunity cost
of retained earnings to the shareholders is the rate of return which they can
get by investing the after tax dividends in the other alternative
opportunities. It can be expressed as-
(1 – Ti) D
Kr = -------------
(1 – To) P
Kr = -------------
(1 – To) P
Here : Ti = Tax rate applicable to individual
To = Capital gain tax
D = Dividend
P = Price of the share.
(5) Cost of Depreciation Funds. Depreciation funds though appear to be cost-less but this is
not so. Their cost too, like cost of retained earnings, are calculated on the
basis of opportunity cost to the shareholder. If an internal projects cannot
earn the rate that the equity shareholders can obtain by investing the funds
elsewhere, money should be distributed to equity shareholder s liquidating
dividend.
Meaning of Cost of
Retained Earnings
The company is not to pay any dividends on retained
earnings, it is therefore, observed that this source of finance is cost free.
This view seems to be based
on the assumption that the company is a separate entity from its shareholders
and it pays nothing to the shareholders to withhold these earnings. But this
view is not correct. Retained earnings involve an opportunity cost. The opportunity
cost of retained earnings is the dividend foregone by the shareholders by not
putting funds elsewhere. Thus cost of Retained earnings is the return expected
by the company.
From shareholders' point of
view, the opportunity cost of Retained earnings is the rate of return that they
can obtain by putting after tax dividend in some other securities of equal
qualities, if earnings are paid to them as dividend in cash. And individual
pays income tax on dividend hence he would only be able to invest the amount
remained after paying individual income tax on such earnings. The value of his
shares would also be increased in the market by an amount which after making
provisions for any tax on capital gains, is equal to the net dividend he would
have received after tax. It shows that necessary adjustments should be made for
individual income tax and capital gain tax on such expected earnings to the
shareholders in determining the opportunity cost to them. This can be expressed
as follows-
(1 – Ti) D
Kr = -------------
(1 – To) P
Kr = -------------
(1 – To) P
Here
: Kr
= Cost of retained earnings
Ti = Marginal income tax-rate applicable to an individual
To = Capital gain tax
D = Dividends per share
P = Price of share.
Meaning of Weighted Average Cost of Capital
A company has to employ
owner's funds as well as creditors' funds to finance its project so as to make
the capital structure of the company balanced and to increase the return to the
shareholders.
The total cost of capital is
the aggregate of costs of specific capitals. In financial decision making, the
concept of composite cost is relevant. The composite costs of capital is the
weighted average of the cost of various sources of funds, weights being the
proportion of each source of funds in the capital structure. It should be
remembered, tat it is weighted average, and not the simple average, which is
relevant in calculating the overall cost of capital. The composite cost of all
capital lies between the leas t and the most expensive funds. This approach
enables the maximizations of corporate profits and the wealth of the equity
shareholders by investing the funds in a project’s earnings in excess of the
cost of its capital-mix.
Weighted average, as the
name implies, is an average of the costs of specific source of Capital employed
in a business, properly weighted by the proportion, they hold in the firm's
capital structure.
Weighted Average, How
to Calculate?
Though the concept of weighted average cost of capital is
very simple, yet there are so many problems in the way of its calculations.
Its computation requires two steps.
(i) Computation of weights to be assigned to each type of funds,
and
(ii) Assignment of cost to various sources of capital.
Once these values are known, the calculation of weighted average cost becomes very simple. It may be obtained by adding up the products of cost of all types of capital multiplied by their appropriate weights.
