Debt-equity & financial leverage

Every company uses some mix of debt and equity to fund its operations. The debt-to-equity (D/E) ratio tells you how aggressively a company is leveraging borrowed money.

The formula

D/E ratio = Total Debt ÷ Shareholders' Equity

D/E of 1 means: for every ₹1 of equity, the company has ₹1 of debt.

D/E of 3 means: ₹3 of debt for every ₹1 of equity, highly leveraged.

Why debt is a double-edged sword

Debt amplifies returns when times are good. A company borrowing at 8% and earning 15% on that capital makes a 7% spread, paid to shareholders.

But debt amplifies losses when times are bad. Interest must be paid regardless of revenue. In downturns, over-leveraged companies face bankruptcy while their competitors with clean balance sheets survive and gain market share.

> Two companies can carry identical leverage: the one with stable cash flows services it through the cycle; the one without collapses under it.

Sector context matters

• Banks: inherently high D/E (lending is their business). D/E of 8–10 is normal for banks.
• Infrastructure: capital intensive, moderate debt is expected.
• Consumer goods: should have near-zero debt. High D/E here is a red flag.
• IT companies: ideally zero debt. Cash-rich balance sheets.

D/E < 0.5Generally conservative and financially safe

D/E > 2Elevated risk. Verify the company has stable cash flows to service debt

Interest coverage ratio

Interest Coverage = EBIT ÷ Interest expense

This tells you how many times over the company can pay its interest from operating profits. Below 1.5: danger zone. Above 3: healthy. Above 5: very comfortable.

Takeaway. D/E ratio measures leverage. High debt amplifies both gains and losses. Context matters. IT companies should be near-zero debt; banks are inherently leveraged. Always check interest coverage.
