Borrowed money is called leverage. Used well, it can increase the return to owners. Used badly, it can magnify losses and, in the worst case, threaten the company's survival.
The obligation to pay interest does not pause when business slows. A company with heavy debt must keep paying whether sales are strong or weak — that is the core risk.
Why industries differ
| Type of business | Typical relationship with debt |
|---|---|
| Banks and lenders | Borrowing is central to the business model; their ratios are judged differently |
| Stable utilities | Often carry more debt because cash flows are predictable |
| Cyclical manufacturers | Heavy debt can be risky when demand swings |
| Asset-light services | Often carry little debt |
What is normal depends on the industry, not a single rule.
This is why comparing one company's debt-to-equity with a firm in a different industry tells you very little. Compare it with close peers and with its own history.
Debt-to-Equity Ratio
How much borrowed money the company uses for every rupee of owners' money.
Debt / Equity = Total Debt ÷ Shareholders' Equity
Debt / Equity

Debt is not automatically bad — it can fund growth more cheaply than issuing shares. What matters is whether the business earns more on that capital than the interest it pays, and whether its cash flows can comfortably service the debt. Capital-intensive industries tend to carry more debt than asset-light ones.
Look at the direction
Watch the trend, not just the level. A rising debt-to-equity ratio alongside flat profits is a prompt to ask how the interest will be paid.
It also helps to check interest coverage — how many times operating profit covers the interest bill — because that shows how comfortably the debt is being serviced.
