A company can fund itself in two ways: with equity, the shareholders' money (what they put in plus profits kept in the business), or with debt, money borrowed from banks, bondholders and other lenders. Equity does not have to be paid back and has no fixed cost. Debt has to be repaid on schedule and carries interest whether the business is doing well or not. The debt to equity ratio shows the balance between the two, and it is one of the first numbers to check when judging how risky a company is.
The formula
Debt to equity = total borrowings ÷ shareholders' equity
Total borrowings means long-term loans plus short-term loans, including bonds and debentures, from the balance sheet. Many analysts also add lease liabilities, which work like debt. Shareholders' equity (also called net worth) is share capital plus reserves.
A ratio of 0.5 means the company has borrowed ₹50 for every ₹100 of owners' money. A ratio of 2 means lenders have put in twice as much as owners.
Why debt cuts both ways
Borrowing is not bad in itself. If a company can borrow at 9% and earn 18% on the money, the extra goes to shareholders and pushes up return on equity. This is called leverage. The problem comes when business slows. Revenue falls, but interest does not. A company with little debt can ride out a bad year; a heavily indebted one may have to sell assets, raise new shares at a low price (diluting existing holders), or in the worst case default.
A worked example
Two cement companies each earn operating profit (EBIT) of ₹1,000 crore in a normal year and have ₹5,000 crore of equity.
| Item (₹ crore) | Company A | Company B |
|---|---|---|
| Borrowings | 1,000 | 7,500 |
| Debt to equity | 0.2 | 1.5 |
| Interest at 9% | 90 | 675 |
| Interest cover (EBIT ÷ interest) | 11.1× | 1.5× |
| EBIT in a bad year (falls 40%) | 600 | 600 |
| Interest cover in the bad year | 6.7× | 0.9× |
In the bad year, Company A still earns more than six times its interest. Company B no longer earns enough to pay its interest from operations at all; it must use cash reserves, borrow more, or sell something. Same business, same profit, very different risk, entirely because of the debt.
Interest cover and net debt
Two companion measures make the ratio far more useful:
- Interest coverage ratio = EBIT ÷ interest expense. It shows how many times over the company can pay its interest from operating profit. Below about 2 to 3 leaves little room; many lenders watch this closely.
- Net debt = borrowings − cash and liquid investments. A company with ₹3,000 crore of debt and ₹2,800 crore of cash is close to debt-free in practice. A negative net debt (more cash than debt) is called a net cash position.
- Net debt to EBITDA tells you how many years of operating profit it would take to repay the debt. Lenders and rating agencies use it widely.
Where to find the numbers
Borrowings and equity come from the balance sheet, published with the annual results and, for listed companies, also at the half year (check the current disclosure rules). Look for:
- Non-current borrowings: loans and bonds due after more than a year.
- Current borrowings: short-term loans, working capital lines and commercial paper, plus the part of long-term loans due within a year.
- Lease liabilities: rent commitments that accounting rules now treat like debt, important for retailers, airlines and restaurant chains.
- Total equity: equity share capital plus other equity (reserves). In consolidated accounts, use the part belonging to the company's own shareholders.
Interest expense is the "finance costs" line in the quarterly results, so interest cover can be tracked every quarter even though full balance sheets come less often. A quickly rising finance cost is often the first hint that debt is climbing. Credit ratings from rating agencies, mentioned in company announcements, are another outside view of how lenders see the company.
What is "normal" depends on the sector
| Type of business | Typical debt profile |
|---|---|
| IT services, FMCG brands | Often little or no debt; cash rich |
| Manufacturing, cement, chemicals | Moderate debt to fund plants |
| Power, roads, telecom, real estate | High debt, long projects, steady or contracted income |
| Banks, NBFCs, housing finance | Very high by design: borrowing and lending is the business |
For banks and finance companies, debt to equity is not the right measure. Their deposits and borrowings are raw material. Look instead at capital adequacy (how much capital they hold against risky loans), bad loans (NPAs) and asset quality. Comparing a bank's debt to equity with a cement maker's is meaningless.
Live example: debt and the price trend
Debt matters most when interest rates rise or business slows, and both tend to show up in the share price before they show up in the next results. Here is a live box for Reliance Industries, a large company that has borrowed heavily at times to build new businesses:
Compare the price with its 200-day average and check the RSI: for indebted companies, a long slide below the average often reflects worries about debt or interest costs long before the balance sheet is updated. The screener lets you combine a debt filter with these price measures.
How investors use it
- Screening out fragile balance sheets: many investors set a maximum debt to equity (for example 0.5 or 1) outside financial companies.
- Watching the trend: debt rising quarter after quarter while profit is flat is a warning; debt falling as cash flow repays it is usually a strength.
- Checking against cash flow: debt is repaid from cash, not profit. The cash flow statement shows whether operations generate enough.
- Combining with promoter pledges: borrowing by the company and by its promoters (see promoter pledge) can amplify each other in a downturn.
- Interest rate cycles: when the RBI raises rates, indebted companies' costs rise; when rates fall, they benefit most.
Limits and common mistakes
- Ignoring cash. Gross debt can look high when the company also holds large cash. Use net debt.
- Missing hidden debt. Leases, guarantees given for group companies and supplier credit do not always appear as borrowings. Read the notes.
- Negative equity. If losses have wiped out equity, the ratio becomes negative or meaningless; that is itself a serious warning.
- Using one year. Debt often peaks while a new plant is being built and falls after it starts earning. Look at several years.
- Applying it to banks. Use capital adequacy and asset quality instead.
