A bad product can be fixed. A bad hire can be replaced. Too much debt at the wrong moment wipes out the equity and never gives it back. Some of the worst wealth destruction on Indian exchanges came from businesses with real customers and real revenue, where interest ate the cash flow and the cycle turned before the debt did.
I trade derivatives, so I think about leverage as a position size. Debt does not make a business better or worse. It makes every move bigger, in both directions, and it puts a date on your survival. This module gives you the ratios, the maths, and the one table in the annual report most investors never open.
- Net debt to EBITDABelow about 3 for most non financial sectors.
- Interest coverAbove 3 as a floor, above 5 for comfort.
- Maturity profileNo single year carrying a large share of the debt.
- Cash flow stabilityVolatile earnings need less debt.
- Hidden debtLeases, guarantees, pledged promoter shares.
The three core leverage metrics
No single ratio is enough. Net debt to EBITDA tells you the size of the debt. Interest coverage tells you whether this year's profit can carry it. Neither tells you when the debt is due, and that is often what kills a company.
How leverage amplifies equity returns, and losses
Two illustrative businesses, round numbers. Each earns ₹100 crore of EBIT. Business A has no debt. Business B has ₹500 crore of debt at 10%, so ₹50 crore of interest a year. To keep it simple, ignore tax.
| Illustrative, ₹ crore | EBIT | A: earnings to equity | B: earnings to equity |
|---|---|---|---|
| Base year | 100 | 100 | 50 |
| Good year, EBIT +20% | 120 | 120 (+20%) | 70 (+40%) |
| Bad year, EBIT −30% | 70 | 70 (−30%) | 20 (−60%) |
| Severe year, EBIT −55% | 45 | 45 (−55%) | −5 (loss) |
- A, good year20%
- B, good year40%
- A, bad year-30%
- B, bad year-60%
- A, severe year-55%
- B, severe year-110%
Change in earnings to equity against the base year. Illustrative businesses, ₹500 crore debt at 10% for B, tax ignored.
In the severe year Business B cannot pay its interest from operating profit. A temporary problem in the business becomes a solvency problem for the shareholder. That is the asymmetry: the upside from debt is a bigger good year, the downside is losing the company.
Rates matter too. The RBI raised the repo rate by 25 basis points to 5.50% on 7 Oct 2026 and moved its stance to calibrated tightening. For a company with ₹2,000 crore of floating rate loans, a 25 basis point rise in its borrowing cost is ₹5 crore a year of extra interest. Small for a company with interest cover of 8. Not small for one with cover of 1.5.
RBI, Monetary Policy Statement, 7 Oct 2026The maturity wall: when the debt is due
The ratios describe a balance sheet on one day. Lenders care about the next 12 months. A company can show a comfortable 2.5 times net debt to EBITDA and still be in trouble if most of its borrowing is due in the same year and the credit market shuts. India saw exactly that pattern when the NBFC funding market froze after a large infrastructure lender defaulted in 2018: companies that depended on rolling over short term paper found nobody to roll it with.
The fix is a habit. Open the notes to accounts and find the maturity table for borrowings, which the financial risk note on liquidity usually shows by bucket: within a year, one to five years, beyond five years. Then ask three questions.
- How much is due within a year, and how does it compare with cash plus a year of operating cash flow?
- Is any one year carrying a large share of the debt? I get uneasy when one year holds more than about a third.
- Is short term debt funding long term assets? Commercial paper paying for a plant that takes five years to earn back is a rollover bet.
Illustrative example. A company has ₹2,000 crore of gross debt and net debt to EBITDA of 2.5. ₹1,100 crore, 55% of it, falls due in the next 12 months. Cash is ₹200 crore and operating cash flow is about ₹400 crore a year. If lenders roll over the debt, nothing happens. If they do not, there is a ₹500 crore hole that has to be filled by selling assets, issuing shares at a bad price, or defaulting. The ratio looked fine. The calendar did not.
Since 1 January 2020, listed companies have had to disclose a default on loans from banks and financial institutions within 24 hours if it continues beyond 30 days, under a SEBI circular of November 2019. So a default is now public quickly. Your job is to see the wall before the disclosure.
What happens when it goes wrong: the IBC
When a company cannot pay, creditors can take it to the National Company Law Tribunal under the Insolvency and Bankruptcy Code, 2016. The corporate insolvency resolution process is meant to finish in 180 days, extendable by 90, with an outer limit of 330 days including litigation. Control passes from the promoter to a resolution professional and a committee of creditors.
- Admission and moratorium
Suits and recovery against the company pause; the board is suspended.
- Target to finish
Creditors vote on resolution plans.
- After one 90 day extension
Granted by the tribunal if creditors ask.
- Outer limit with litigation
No approved plan usually means liquidation.
Insolvency and Bankruptcy Code 2016, Section 12, as amended in 2019.
For shareholders the outcome is usually close to nothing. Creditors come first, and even they take a large cut. Under resolution plans up to March 2025, creditors recovered 32.8% of their admitted claims, according to IBBI. That was 93.41% of the fair value of the assets and 170.1% of what liquidation would have fetched, which tells you the claims were far larger than the businesses were worth by the time they arrived.

These bands are my working ranges, not rules. A toll road with 20 years of contracted cash flow can carry more debt than a steel maker at the bottom of the cycle. For banks, the regulator sets the floor: the RBI requires a minimum total capital ratio of 9% plus a capital conservation buffer of 2.5% for scheduled commercial banks, and NBFCs in the middle and upper layers must hold capital of at least 15% of risk weighted assets.
Operating leverage: the amplifier before financial leverage
Operating leverage is the share of costs that stay fixed when revenue moves. High fixed costs mean small changes in revenue produce large changes in EBIT, before any debt enters the picture.
Take an illustrative airline like business with ₹1,000 crore of revenue, ₹700 crore of fixed costs (aircraft leases, crew, maintenance, airport charges) and variable costs of 20% of revenue. EBIT is ₹100 crore. If revenue falls 15% to ₹850 crore, variable costs fall to ₹170 crore but fixed costs stay at ₹700 crore. EBIT becomes a loss of ₹20 crore. A 15% revenue fall wiped out 120% of operating profit. Add debt on top and the equity becomes extremely fragile.
Distribution and trading businesses sit at the other end. Most of their costs move with sales, so the same revenue fall moves EBIT much less. At any given level of debt they are less risky. When you judge leverage, judge both layers together.
Hidden leverage
- Corporate guarantees given for group companies, shown as contingent liabilities in the notes. If the group company fails, the listed company pays.
- Promoter pledges. The company's own debt can be low while the promoter has borrowed heavily against the shares. A falling price then triggers margin calls and selling. The quarterly shareholding pattern shows the pledged share.
- Supplier credit and acceptances. Some companies fund working capital through long supplier credit arranged by banks. It behaves like debt but may sit in trade payables.
- Debt at subsidiaries. Always read the consolidated balance sheet, not only the standalone one.
Common mistakes
MythA low debt to equity ratio means the company is safe.
FactSafety depends on debt against cash flow and on when it is due. A company with modest debt can still fail if most of it matures in one year and lenders stop rolling it over.
- Using the standalone balance sheet. Group debt often sits in subsidiaries.
- Ignoring lease liabilities. Since 2019 they are on the balance sheet. Leave them out and a retailer looks debt free when it is not.
- Reading coverage in a peak year. Recalculate it with EBIT from the worst year of the last cycle.
- Treating a bank like a manufacturer. Bank leverage of 8 to 10 times is the business model. Judge it on capital, asset quality and liquidity.
- Trusting the cash balance. Check that cash is free, not lien marked against loans or held in a subsidiary abroad.
Leverage risk in a stock tends to show up first as falling prices, and RupeeCase strategies are built to react to that rather than to forecast it. They rank NSE index universes on price momentum and sell names that drop out of the top ranks at the next scheduled rebalance, so a stock sliding into a debt crisis usually leaves the portfolio well before an insolvency filing. Some cards also hold a debt or gold sleeve to soften equity drawdowns, for example Large Mid Hybrid. Balance sheet scoring of individual companies is planned for the analysis and research module for qualified investors and institutions. Compare the cards on the strategies page.
Questions readers ask
Is EBITDA the right denominator for leverage?
It is the convention because it approximates cash available before interest and tax. For capital heavy companies, use EBITDA minus maintenance capex as well, since that capex is not optional. A company that has to spend most of its EBITDA to keep the plant running cannot use it to repay debt.
What happens to shareholders in an IBC resolution?
Usually the existing equity is wiped out or heavily diluted, because creditors take large losses first. Under resolution plans up to March 2025 creditors recovered about a third of their admitted claims, per IBBI. Shareholders rank behind them.
Where do I find the debt maturity table?
In the annual report notes, usually under financial risk management, liquidity risk, where borrowings are split by due date. Many companies also show it in their investor presentation or credit rating rationale, which SEBI registered rating agencies publish.
