Debt to equity vs Interest cover
Debt to equity compares how much a company has borrowed with how much its owners have put in. Interest cover compares operating profit with the interest it must pay each year. The first tells you how big the debt is; the second tells you whether the company can comfortably carry it.
| Point | Debt to equity | Interest cover |
|---|---|---|
| Formula | Total debt ÷ shareholders’ equity | Operating profit ÷ interest expense |
| Found in | Balance sheet | Profit and loss statement |
| Measures | Size of borrowing | Ability to pay interest |
| Comfortable | Below 0.5 | Above 5× |
| Needs a closer look | Above 1 | Below 2× is dangerous |
| Changes with profit? | Slowly | Quickly, falls when profit dips |
What each ratio tells you
Debt to equity is a snapshot of the balance sheet. A ratio of 0.5 means the company has borrowed ₹50 for every ₹100 of owners’ money. Debt isn’t bad by itself. Debt growing much faster than the business is.
Interest cover is a flow measure. If operating profit is ₹100 crore and interest is ₹20 crore, interest cover is 5×. The company could see profit fall a lot before it struggled to pay its lenders.
A worked example
Company A has ₹200 crore of equity and ₹300 crore of debt. Debt to equity is 1.5, which looks high. But its operating profit is ₹120 crore and interest is ₹24 crore, so interest cover is 5×. It is borrowing heavily, but the profit carries it.
Company B has ₹200 crore of equity and only ₹100 crore of debt, a ratio of 0.5. But its operating profit is just ₹15 crore against ₹10 crore of interest, so interest cover is 1.5×. The debt is smaller, yet one weak year could leave it unable to pay.
Reading them together
Look at both, and at their direction over a few years. Falling interest cover tells you lenders are taking a bigger slice every year. Rising debt to equity alongside falling interest cover is the combination that most deserves your attention.
Banks and NBFCs borrow by design, so these ratios don’t apply to them in the usual way. Judge them on bad loans and lending margins instead.
When to use which
Use debt to equity to see how much the company leans on borrowed money. Use interest cover to see whether its profit can safely carry that debt. A company with low debt to equity and high interest cover is on firm ground.
Common questions
Which is more important, debt to equity or interest cover?
Interest cover often matters more in the short term, because it shows whether the company can pay its lenders. Debt to equity shows the bigger structural risk.
What is a safe interest coverage ratio?
Above 5× is generally considered safe. Below 2× is dangerous, because a small fall in profit can make interest hard to pay.
Is a debt to equity above 1 always bad?
Not always. Some capital-heavy businesses carry more debt, but it deserves a closer look at interest cover and cash flow.
