The financial requirement of a firm can be met through ownership capital and/or borrowed capital. The ownership capital refers to the amount of capital contributed by the owners. In case of a company, it refers to the amount of funds raised by issuing shares. The main characteristic of the ownership capital is that its contributors are entitled to get dividend out of earnings after the payment of interest and taxes. Hence, the rate of return on such capital depends upon the level of profits earned, and, if there are no profits, no dividend may be paid.


Borrowed capital, on the other hand, refers to the amount of funds raised through long term loans and debentures on which its contributors are entitled to a fixed rate of interest which has to be paid at regular intervals (half-yearly or yearly) irrespective of the profits earned. There is also a commitment that the principal amount shall be repaid on maturity. However, it is still considered advantageous to finance business activities through borrowed capital because if the rate of earnings from the planned business investment is expected to be better than the rate of interest on the borrowed funds, it shall ensure higher returns on owners’ funds. Let us take an example and understand this concept more clearly.


“The mix of equity and debt actually used by a company for meeting its requirement of capital is known as its capital structure.”


Thus, the term capital structure refers to the makeup of a firm’s capital in terms of the planned mix of different kinds of long-term funds like equity shares, preference shares, debentures and long term funds. So capital structure involves two basic decisions:


(a) The type of securities to be issued or raised; and

(b) The relative proportion of each type of security


Factors Determining the Capital Structure


  1. Expected earnings and their stability: If the expected earnings, in terms of rate of return on the amount to be invested are sufficiently large, use of debt is considered quite desirable. Not only that, the stability of earnings should also be taken into account because if the firm is engaged is business activities in which sales and profits are subject to wide fluctuations, it will be risky to use higher proportion of debt. In other words, if there is an element of uncertainty about the expected earnings it is considered better to rely more on equity share capital. However, with assured prospects of rising earnings, there should be greater reliance on debt so as to take advantage of leverage effect.


  1. Cost of debt : If the rate of interest on borrowings is lower than the expected rate of return on capital employed, then debt may be preferred. With lower cost of debt financing, the overall cost of financing is reduced and the return on equity capital will be higher, as explained earlier.


  1. Right to manage the business: You know that the debenture holders and preference shareholders do not have much say in management of the company. This authority lies primarily with the equity shareholders who have the voting rights. Hence, while deciding on the mix of equity and debt, the promoters/existing management of the company may also take into account the possible effect of raising funds through equity shares on the right to control the business. In order to retain their right to control the affairs of the company, they may prefer to raise additional funds mainly through debentures and preference shares.


  1. Capital market conditions: The conditions in the capital market also influence the capital structure decision. At times capital market is so depressed that the investors are unwilling to subscribe to shares. In such a situation, it is considered better to rely on debt or defer the decision till a favourable market condition is restored.


  1. Regulatory norms : While deciding on the capital structure, the legal constraints like the limit on debt-equity ratio should also be kept in view. At present, such limit is 2:1 in most cases. This implies that at any point of time, the debt should not be more than twice the amount of share capital. This limit keeps on changing with changing economic environment and varies from industry to industry.


  1. Flexibility: The planned capital structure should be flexible enough to raise additional funds without much difficulty. The company should be able to raise additional capital in the form of debt or equity whenever required. But if the company’s capital structure has too much debt, then the lenders may not be able to give more loan to the company. In a such a situation it may be forced to raise the funds only through shares for which the capital market condition may not be conducive. Similarly, when on account of declining business and lack of other investment opportunities the funds need to be refunded, it may not be possible to do so if the company has heavily relied on equity shares which cannot be redeemed easily. Hence, to ensure an element of flexibility, it is better if the firm relies more on redeemable securities that can be paid off if necessary and, at the same time, have some unused debt raising capacity so that future financial needs can be fully taken care of without much difficulty.


  1. Investors’ attitude towards investment: While planning the capital structure of a company one must bear in mind that all investors do not have the same attitude towards their investment. Some are highly conservative who prefer safety to return. For such investors, debentures are considered most suitable. As against this, there are some who are interested in high return on their investments and are ready to take the risk involved. Such investors prefer equity shares. Then, there are many who are willing to take a limited risk provided the return is better than the rate on secured debentures and bonds. Preference shares are most suitable for this category of investors. In order to attract all categories of investors, it is considered more desirable to issue different types of securities especially when the amount of capital requirement is large.




The primary meaning of cost of capital is simply the cost an entity must pay to raise funds. The term can refer, for instance, to the financing cost (interest rate) a company pays when securing a loan.


In other words, Cost of capital refers to the opportunity cost of making a specific investment. It is the rate of return that could have been earned by putting the same money into a different investment with equal risk. Thus, the cost of capital is the rate of return required to persuade the investor to make a given investment.


The cost of various capital sources varies from company to company, and depends on factors such as its operating history, profitability, credit worthiness, etc. In general, newer enterprises with limited operating histories will have higher costs of capital than established companies with a solid track record, since lenders and investors will demand a higher risk premium for the former.
