Each and every business or company requires money to smoothly function, expand its operations, and remain stable in terms of finances. The companies arrange the funds through different ways, like selling shares (equity), borrowing loans or using a mix of both. This is called a company’s capital structure. defines the cost of capital for the company, affects its profitability, and indicates its level of financial risk (e.g., greater debt levels raise the risk of bankruptcy).
Understanding the types, importance, and meaning of capital structure helps a company make well-informed decisions related to financial planning, performance, and when comparing itself with other companies. Capital structure is a significant aspect of money handling and planning for businesses of all sizes. It enables a company to obtain loans and remain healthy for many years—not only make profits.
Capital structure refers to the way a business utilises a combination of borrowed capital (loans) and its own money (equity) in order to operate its day-to-day operations, expand operations, and remain healthy financially. It is like a blueprint that guides the business in making informed choices regarding the amount of money to be borrowed and the amount to utilise from its own funds.
The capital structure of a company illustrates how it arranges money to operate its business and settle its bills. It also facilitates decisions regarding investment, risk, and profit. Opting for an appropriate proportion of loans and its own capital can reduce expenses and make the business strong in the long term.
Here’s an example:
If a firm uses 60% of its own money and 40% of its loan, it minimises repayment pressure while retaining control and ensuring steady growth.
A company can have different types of capital structures depending on how they arrange their financing. Each capital structure can have distinctions in ownership, financial risk and cost of raising capital.
Equity capital is the money a company raises from shareholders or owners. The funds do not have to be repaid, but ownership dilution will occur with shared ownership. Primarily, equity capital is used for long-term expansion of the business.
Debt capital generally consists of money borrowed from outside sources in the form of loans or bonds, and the funds must be repaid with interest within an agreed timeframe. Debt capital has more tax benefits than equity capital, and while borrowing to fund growth can generate shareholder value, too much borrowing of loans can lead to financial distress.
Hybrid capital, as the title suggests, has the elements of both loans as well as equity. Preference shares (fixed dividends like debt, no voting rights like equity) and convertible debentures (debt convertible to equity) are examples of hybrid capital. Hybrid capital gives more flexibility and usually it's used by larger companies for tax efficiency..
An optimal capital structure balances debt and equity to minimise funding costs while aligning with the company's risk profile and growth needs. When structured effectively, it enhances returns and financial performance by ensuring borrowed capital generates higher returns than its cost.

To best understand the company's money from loans compared to the total money, you should have an understanding of the capital structure formula. It provides a quick view of how the company generates its funds. Here is the formula:
Capital Structure = (Total Debt ÷ Total Capital) × 100
This formula will help figure out the portion of loans in total capital. This will give the company an idea of the loan funds that are being utilised.
In order to understand how capital structure is determined, let us understand through an example of a real-life business situation.
Example:
Suppose a company has taken a loan of Rs 50 Lakh and it has Rs 50 Lakh own money (equity). Here, the capital structure is 50:50, meaning the company is using an equal amount of borrowed money and own funds to finance its operations.
