Debt-to-equity (D/E) is one of the first numbers worth checking on any stock you hold. It's a quick read on how much risk a company has taken on to fund itself. But there is no single “good” number that applies to every stock — what's healthy for a cement maker would be alarming for an IT services firm. Here's how to read it properly.
What debt-to-equity actually measures
D/E compares a company's total debt to its shareholders' equity. A ratio of 1.0 means the company owes as much as shareholders have put in; a ratio of 0.3 means it's mostly equity-funded with modest debt. Higher leverage magnifies returns in good times and losses in bad times, and it adds fixed interest costs the company must pay regardless of how business is going.
A quick note on units: D/E is sometimes quoted as a ratio (0.5) and sometimes as a percentage (50%). They mean the same thing — just confirm which form a source is using before you compare.
Healthy ranges by sector
The “right” level of debt depends entirely on how stable and capital-intensive the business is. Broad rules of thumb for Indian stocks:
IT services & FMCG (low debt expected)
Asset-light, cash-generative businesses like IT services and consumer staples typically run very low leverage — often near 0 to 0.3. Here, meaningful debt is unusual and worth questioning.
Manufacturing & capital goods (moderate)
Companies that build plants and carry inventory reasonably take on more debt. A D/E up to around 0.5 to 1.0 can be perfectly healthy if cash flows are steady and interest is comfortably covered.
Infrastructure, power & real estate (high by nature)
Heavily capital-intensive sectors routinely run D/E above 1.0, sometimes well above. The question isn't “is debt high?” — it will be — but “is it under control and well-serviced?”
Banks & NBFCs (don't apply D/E the same way)
For lenders, debt is raw material, not a warning sign — D/E figures look enormous and aren't comparable to other sectors. Use capital-adequacy and asset-quality measures instead.
Red flags to watch
A number in isolation isn't enough. Watch for leverage that is rising quarter after quarter, debt growing faster than revenue, or interest costs eating an increasing share of operating profit. A high but stable, well-covered D/E is usually fine; a moderate but rapidly climbing one can be the earlier warning.
Putting it in context
Debt-to-equity is one input, not a verdict. Read it alongside revenue growth, margins, and return on equity — the same metrics covered in our guide on how to analyze your portfolio. Judged together, and tracked every quarter, they tell you whether a holding is genuinely healthy or quietly getting riskier.
