Debt has a bad reputation it only half deserves. Borrowing is how a cement company builds a plant it could never fund from a single year's profit, and how a growing manufacturer holds enough stock to serve a season it has not yet sold into. What debt actually does is magnify — it makes a good year better for the owners and a bad year considerably worse, because the interest and the repayment fall due whether the sales arrive or not. This topic is about reading how much of that magnification a company has taken on: the ratios that measure it, the one that signals trouble first, and the thing none of the ratios can see, which is when the money is due.
Is debt actually bad for a company?
No, and treating it as automatically bad will make you misread most of the industrial and infrastructure half of the Indian market. Debt is cheaper than equity for two structural reasons: lenders accept a lower return because they are paid before shareholders and usually hold security over assets, and the interest a company pays is deductible against tax while dividends are not. A business that can earn more on borrowed money than the borrowing costs makes its owners better off by borrowing.
What debt does is magnify, in both directions and by the same arithmetic. Suppose a business earns a 15 per cent return on its capital and borrows a slice of that capital at 9 per cent. The six-point spread accrues entirely to the shareholders, so their return rises. Now suppose a downturn takes the return on capital to 6 per cent. The 9 per cent interest is unchanged and still contractually due, so the shortfall also comes entirely out of the shareholders' return. The lever that lifted is the same lever that drops.
The difference between the two cases is not the debt. It is the volatility of the operating profit underneath it. A regulated utility with contracted revenue can carry a debt load that would be reckless for a commodity chemicals maker whose realisations swing with global prices. This is why debt ratios have to be read alongside how cyclical the business is, and why a single threshold applied across sectors is worthless.
Note — The question is never how much debt a company has in absolute rupees. It is whether the operating cash flow, in a bad year rather than a good one, comfortably covers the interest and the repayments that fall due in that same year.
Gross debt or net debt — which should you use?
Gross debt is everything the company has borrowed: long-term loans, the portion of them falling due within twelve months, working capital facilities, commercial paper, debentures and any lease liabilities recognised on the balance sheet. It is the sum the company is contractually obliged to repay.
Net debt subtracts cash and liquid investments from that figure, on the reasoning that money sitting in a bank account could be used to repay borrowings tomorrow. For a company with genuine surplus cash this is the more honest measure of the burden, and it is what analysts and rating agencies generally quote.
But net debt carries an assumption that is worth testing rather than accepting. It presumes the cash is actually available. Cash held in an overseas subsidiary that would be taxed on repatriation, cash pledged as margin or as debt service reserve, and cash that is really the float of a business with large customer advances are all counted in the netting and none of them can be reached to repay a loan. The cash and bank balances note in the annual report separates restricted from unrestricted balances, and reading it takes a minute.
Gross debt is also the figure that determines the interest bill. A company can hold Rs 150 crore of cash earning a low deposit rate while paying a much higher rate on Rs 600 crore of borrowings. Net debt makes that look better than it is on the profit and loss statement, where the full gross interest is charged.
Gross debt = Long-term borrowings + Short-term borrowings
+ Current maturities of long-term debt + Lease liabilities
Net debt = Gross debt - Cash and cash equivalents - Liquid investments
Konkan Ceramics Ltd (figures illustrative, not a real company):
Gross debt Rs 600 cr - Cash and liquid investments Rs 150 cr = Net debt Rs 450 cr- Current maturities of long-term debt sit inside current liabilities in the balance sheet, so a reader who takes only the 'long-term borrowings' line understates gross debt
- Check the cash and bank balances note for restricted balances before netting them off
Debt-to-equity, and how to read the bands
Debt-to-equity divides total borrowings by shareholders' funds. It answers a structural question: for every rupee the owners have in this business, how many rupees have the lenders put in?
Konkan Ceramics carries Rs 600 crore of gross debt against Rs 500 crore of shareholders' funds, so its gross D/E is 1.20. Net of its Rs 150 crore of cash, net D/E is 0.90. Both are worth quoting, because the gap between them tells you how much of the apparent leverage is offset by liquidity the company actually holds.
The bands below describe what different levels mechanically imply, not what any of them recommends. And the ratio has two real weaknesses. It uses book equity, which is a historical accounting figure — a company that has taken large past losses has an eroded net worth, so its D/E looks alarming even if the operations now generate plenty of cash, while a company that revalued its land upward looks conservatively financed on paper. And it says nothing at all about whether the debt can be serviced, because it never touches the profit and loss statement.
| Gross D/E | What it mechanically implies | What to check next |
|---|---|---|
| Below 0.5 | Owners have funded most of the asset base; the interest bill is small relative to operating profit and a rate cycle barely registers in the P&L | Whether the balance sheet is underused — very low leverage in a stable business can mean capital sitting idle |
| 0.5 to 1.0 | A conventional mix for a manufacturer; lenders fund a meaningful minority of assets and interest is a visible but not dominant cost | Interest coverage and the direction of D/E over five years |
| 1.0 to 2.0 | Lenders have put in as much as or more than the owners; profit before tax becomes noticeably sensitive to both sales and interest rates | The maturity schedule, and whether the borrowing funded capacity or losses |
| Above 2.0 | The business is financed mostly by lenders, so a rate rise or a demand dip hits profit before tax well before it shows up in revenue | Interest coverage first, then near-term repayments against operating cash flow |
Watch out — Book equity can be manufactured. Revaluation reserves inflate it, accumulated losses hollow it out, and a large buyback shrinks it deliberately. Never read D/E without glancing at what the equity is actually made of in the reserves note.
Net debt to EBITDA — how many years of earnings would clear this?
This is the more useful of the two structural measures, because its denominator is earnings rather than an accounting balance. It asks a question anyone can picture: if the company devoted its entire annual operating cash generation to repayment and nothing else, how many years would it take to clear the borrowings?
Konkan Ceramics generates EBITDA of Rs 180 crore against net debt of Rs 450 crore, so the answer is 2.5 years. On gross debt it is 3.3 years. That is a far more intuitive statement of a debt load than 'D/E of 1.2', and it is directly comparable across companies of different sizes in the same industry.
EBITDA is used rather than net profit for a specific reason: it approximates the cash the operations throw off before the financing and tax decisions, and lenders care about the cash available to service them, not the accounting profit after they have been paid. The approximation has a well-known flaw, though. EBITDA adds back depreciation, and depreciation is a real economic cost for a company whose plant genuinely wears out and must be replaced. A cement or steel business with heavy maintenance capital expenditure cannot in fact use its full EBITDA to repay lenders, because a large part of it has to go back into keeping the plant running. Loan covenants are frequently written on this ratio, which is one reason it is worth computing the way a lender would.
Net debt / EBITDA = Net debt / (EBIT + Depreciation and amortisation)
Konkan Ceramics:
EBITDA = EBIT 120 + Depreciation 60 = Rs 180 cr
Net debt / EBITDA = 450 / 180 = 2.5 times
Gross debt / EBITDA = 600 / 180 = 3.3 times- EBITDA = earnings before interest, tax, depreciation and amortisation — roughly the cash the operating business generates before paying lenders or the government
- A cyclical company should be tested on trough EBITDA, not the current year's, because that is the year the ratio has to hold up in
Interest coverage — the ratio that signals distress first
Every other measure on this page describes the size of the debt. Interest coverage describes whether the company can currently afford it, and that is why it deteriorates before anything else does.
The logic is one of sequence. A business under pressure does not default on its principal first — the principal is not due yet. It struggles with the interest, which falls due every quarter regardless of how sales are going. So the first visible sign of strain is operating profit shrinking relative to a fixed interest bill, and interest coverage is exactly that comparison. D/E and net debt to EBITDA are photographs of the balance sheet; interest coverage is a live reading of the pressure on it.
Konkan Ceramics earns EBIT of Rs 120 crore against an interest cost of Rs 48 crore, so coverage is 2.5 times. Read that as a cushion: operating profit could fall by 60 per cent before the company stopped covering its interest from operations. Now run the same sum on a bad year. If a demand slowdown took EBIT to Rs 70 crore, coverage would be 1.5 times and the cushion would be down to a third. If it took EBIT to Rs 48 crore, coverage would be 1.0 and every rupee of operating profit would be going to lenders, leaving nothing for tax, dividends, capital expenditure or the repayment of principal.
That is what makes coverage the one to watch. It converts a debt load into the only unit that matters — how far the business can fall before the obligation stops being comfortably payable.
Interest coverage = EBIT / Interest expense
Konkan Ceramics:
120 / 48 = 2.5 times
EBITDA-based variant (the lender's version):
180 / 48 = 3.75 times
Stress test the same ratio:
EBIT falls 40% to Rs 72 cr -> 72 / 48 = 1.5 times
EBIT falls 60% to Rs 48 cr -> 48 / 48 = 1.0 times- Interest expense is in the finance costs note; take the gross figure, not net of interest income, and check whether any interest has been capitalised into an asset under construction
- Capitalised interest does not appear in the P&L at all, so a company mid-project can show better coverage than its actual cash interest outgo supports
Pro tip — Compute coverage on the worst EBIT of the last decade rather than the latest one. A ratio that survives a trough is telling you something; a ratio that only works at the top of a cycle is telling you when it will stop working.
The four leverage measures side by side
No single ratio captures a debt position. Each of the four below sees something the others miss, and the reason to run all four is that they fail in different places — a company can look reasonable on two and strained on the other two, and that combination is itself the finding.
| Measure | What it captures | What it misses |
|---|---|---|
| Debt to equity — 1.20x gross, 0.90x net | The structural split between lenders' money and owners' money in funding the asset base | Says nothing about affordability; distorted by revaluation reserves and by an equity base eroded by past losses |
| Net debt to EBITDA — 2.5x | The size of the burden expressed in years of operating earnings; the measure most loan covenants use | Adds back depreciation, so it overstates repayment capacity for any business with heavy maintenance capital expenditure |
| Interest coverage — 2.5x on EBIT | Whether this year's operating profit comfortably services this year's interest, and how far profit could fall before it does not | Only covers interest, not repayment of principal; flattered when interest is capitalised into a project under construction |
| Maturity profile — Rs 250 cr due within 12 months | When the money is actually due, which is the dimension every ratio above averages away | Assumes disclosed schedules hold; refinancing risk depends on credit markets and the lender relationship, neither of which is in the accounts |
The maturity profile — a company fails on timing, not on totals
This is the part most retail analysis skips, and it is where distress actually happens. A company is not in trouble because it owes money. It is in trouble when it owes money sooner than it can generate it.
Spread Konkan Ceramics' Rs 600 crore of borrowings across the repayment schedule disclosed in the borrowings note and the picture changes character. Rs 250 crore falls due within twelve months. Against that, the company generates roughly Rs 110 crore of cash from operations in a year and holds Rs 150 crore of cash — Rs 260 crore in total, and only if it spends nothing on maintaining its plant, pays no dividend and grows not at all.
Every ratio earlier on this page said the same thing about this company: a debt load in the ordinary range for a manufacturer. The maturity schedule says something the ratios cannot — that the next twelve months depend on refinancing. In practice the loan will very likely be rolled over, because that is what normally happens, and the company will carry on. But the company no longer controls its own outcome. It is now dependent on lenders being willing to renew, which is a decision made by someone else in conditions the company does not set. When credit conditions tighten, refinancing that everyone assumed was routine stops being routine, and companies that were solvent on every ratio run out of time.
The schedule is disclosed. It sits in the borrowings note and in the financial risk management note of the annual report, usually as a table of contractual maturities. Reading it against the cash flow statement takes five minutes and is the single highest-value thing in this topic.
| Repayment due | Rs crore | Against which resources |
|---|---|---|
| Within 12 months | 250 | Cash Rs 150 cr + annual operating cash flow Rs 110 cr, before any capex or dividend |
| Year 2 | 120 | Next year's operating cash flow, which also has to fund maintenance capex |
| Year 3 | 80 | Comfortable if operations hold |
| Year 4 and beyond | 150 | Long-dated; refinancing risk is remote at this distance |
| Total gross debt | 600 |
What does a rate cycle do to fixed and floating debt?
Borrowings carry either a fixed rate agreed for the life of the loan, or a floating rate that resets periodically against a benchmark — in India typically a repo-linked or MCLR-linked rate that moves when the RBI moves policy rates or when bank funding costs change. The split is disclosed in the borrowings note, and it determines how much of a rate cycle lands in the profit and loss statement.
Fixed-rate debt insulates the P&L while the loan runs, but the protection expires at maturity — a company that fixed cheaply and has to refinance into a higher-rate environment takes the increase all at once. Floating-rate debt passes the change through immediately and in both directions: it hurts through a tightening cycle and helps through an easing one.
Suppose 60 per cent of Konkan Ceramics' Rs 600 crore is floating, so Rs 360 crore reprices. A 100 basis point rise adds Rs 3.6 crore to the interest bill. Against EBIT of Rs 120 crore that looks trivial, which is exactly why people dismiss it. But it comes out of profit before tax of Rs 72 crore, so it is a 5 per cent hit to pre-tax profit from a rate move that did not touch a single unit of sales. Interest coverage slips from 2.5 to about 2.3 times. Repeat that across a full tightening cycle of several hundred basis points and a modest-looking exposure becomes a material earnings event.
That is the general shape of the thing worth internalising: for a leveraged company, an interest rate move is a profit event long before it is a demand event. The macro indicators topic in this module covers which other P&L lines respond to the rate, currency and commodity cycles.
Debt taken to build capacity versus debt taken to fund losses
Two companies can both show borrowings rising by Rs 200 crore and be in opposite situations. What separates them is not on the balance sheet — it is in the cash flow statement, and it takes one glance to see.
Debt raised to build capacity shows up as borrowings rising in financing activities and cash going out as capital expenditure in investing activities. There is an asset being created, it appears as capital work-in-progress on the balance sheet, and the management discussion will describe the project with a commissioning timeline. The leverage is temporary in character: it rises while the plant is built, revenue arrives once it is commissioned, and the ratios normalise. During the build, ratios look worse for a reason that has an end date.
Debt raised to fund losses shows up quite differently. Borrowings rise in financing activities while cash from operations is negative or barely positive, and there is no matching capital expenditure — the money went into paying for the running of a business that is not paying for itself. No asset is created, so nothing normalises. Next year the same gap has to be funded again, with a larger interest bill attached to it.
A third pattern sits between them and is easy to miss: debt raised to fund working capital that keeps expanding. Receivables and inventory grow faster than sales, the gap is plugged with short-term borrowing, and the company looks like it is growing while its cash is being absorbed by customers who pay late and stock that does not move. The working capital and cash conversion cycle topic covers how to read that from the balance sheet, and the cash flow statement topic covers the pattern of profit rising while operating cash flow does not follow.
Example — The test is a single comparison. Put the increase in borrowings next to the capital expenditure line in the same year's cash flow statement. If they roughly correspond, an asset is being built. If borrowings rose and capex did not, ask what the money paid for.
The debt that is not on the balance sheet
Every ratio on this page is computed from disclosed borrowings. Some obligations are real, are binding, and never appear in that number, so a company can look moderately leveraged on the face of the balance sheet while carrying commitments that behave exactly like debt.
Contingent liabilities are disclosed in the notes rather than on the balance sheet, because they depend on a future event — disputed tax demands, claims in litigation, and guarantees the company has given on behalf of subsidiaries, associates or joint ventures. None of them is a certainty, which is why accounting keeps them off the face of the statements. But a guarantee given for a struggling subsidiary's loan is an obligation that becomes very real at exactly the wrong moment, and a large disputed tax demand can crystallise as a cash outflow years after everyone stopped thinking about it.
Alongside them sit capital commitments — contracts already signed for capital expenditure not yet incurred — which tell you money is going out whether or not the business wants it to by then. And letters of credit, bill discounting and supply chain finance arrangements can leave a company economically borrowed while the amount sits in trade payables rather than in borrowings.
The practical habit is simple. Read the contingent liabilities and commitments note every time, and compare its total against shareholders' funds. When contingent items are a large fraction of net worth, the leverage ratios you computed above are describing only part of the obligation. The annual report topic in this module covers where these notes sit and which of them carry signal.
- Guarantees given for the borrowings of subsidiaries, associates and joint ventures.
- Disputed tax, excise, GST and customs demands, with the amounts and the stage of appeal.
- Claims against the company not acknowledged as debt, including litigation.
- Capital commitments — contracts signed for capex not yet spent.
- Lease and long-term supply obligations that behave like fixed payments regardless of how the business performs.
Why lenders get paid before shareholders do
This is the fact underneath everything else on the page, and it is a legal ordering rather than a convention. Lenders hold a contractual claim: a fixed amount, on a fixed date, usually secured against specific assets. Shareholders hold a residual claim, which means they own what is left after every other claimant has been satisfied. In a liquidation the order runs through secured creditors, then unsecured creditors, then preference shareholders, and equity holders come last. Under the Insolvency and Bankruptcy Code, when a company is admitted to insolvency proceedings the equity holders' claim is the one that absorbs the loss first, and frequently absorbs all of it.
That ordering is why the same operating profit produces a steady experience for a lender and a volatile one for a shareholder. The lender's Rs 48 crore of interest is taken off the top of Konkan Ceramics' Rs 120 crore of EBIT whether EBIT was Rs 200 crore or Rs 60 crore. Everything after that is the shareholder's, and 'everything after that' is a much smaller number swinging on a much bigger percentage.
So leverage is not only a solvency question. It is a description of how volatile the shareholder's slice will be. Two companies with identical operating businesses and different debt loads offer their equity holders quite different experiences of the same year, and the more leveraged one requires the operating business to be more predictable to justify it. That is the connection between this topic and DuPont analysis, where the equity multiplier is the same fact expressed as a return ratio.
Why none of this applies to banks and NBFCs
Every rule on this page breaks for a lender, and applying them to a bank or an NBFC will produce conclusions that are not merely wrong but backwards.
For a manufacturer, borrowing is a financing choice made outside the business. For a bank, borrowing is the business. Deposits and market borrowings are the raw material a bank buys in order to sell loans, so its balance sheet is deliberately many times its equity. A debt-to-equity ratio that would signal severe distress at a cement company is the ordinary operating condition of a healthy bank. Net debt is meaningless when the institution's assets are themselves loans and its liabilities are themselves deposits. Interest coverage is meaningless when interest paid is the principal cost of goods sold.
Lenders are read through an entirely different set of measures — capital adequacy against a regulated minimum, net interest margin, the CASA mix, gross and net non-performing assets, and the provision coverage ratio. The banks and NBFCs topic in this module covers that framework. If you are looking at a bank, an NBFC, a housing finance company or an insurer, use that one instead of this.
Watch out — A screener will happily compute debt-to-equity for a bank and display a number around ten. That number is not a red flag and it is not comparable with anything else in your list. Filter financials out of any leverage screen before you sort it.
Running a leverage check against a real annual report
Everything here comes from four places in a filed annual report: the balance sheet, the finance costs note, the borrowings note with its maturity schedule, and the contingent liabilities note. Use consolidated figures — debt frequently sits in subsidiaries, and standalone accounts can show a parent company that looks unlevered while the group is not.
The fifteen-minute debt read
- Build gross debt properly: long-term borrowings, short-term borrowings, current maturities of long-term debt, and lease liabilities.
- Subtract only unrestricted cash and liquid investments, after reading the cash and bank balances note for pledged or restricted amounts.
- Compute gross and net D/E, and check the reserves note for revaluation reserves or accumulated losses distorting the equity base.
- Compute net debt to EBITDA, then recompute it on the worst EBITDA of the last five to ten years.
- Compute interest coverage on EBIT, and check the notes for interest capitalised into assets under construction.
- Read the contractual maturity table and set the next twelve months' repayments against cash in hand plus operating cash flow minus maintenance capex.
- Note the fixed versus floating split and work out what 100 basis points does to profit before tax.
- Compare the year's increase in borrowings with the year's capital expenditure in the cash flow statement.
- Read the contingent liabilities and capital commitments note in full and compare the total against shareholders' funds.
- Check the credit rating disclosure and, more importantly, whether the rating or its outlook has changed in the last two years.
Key points
Interest coverage = EBIT / Interest expense; Net debt / EBITDA = (Gross debt - cash and liquid investments) / (EBIT + depreciation and amortisation)
Example — Konkan Ceramics Ltd (figures illustrative, not a real company) carries Rs 600 cr of gross debt and Rs 150 cr of cash against Rs 500 cr of shareholders' funds, so gross D/E is 1.20 and net D/E is 0.90. On EBITDA of Rs 180 cr, net debt to EBITDA is 2.5 years. EBIT of Rs 120 cr against interest of Rs 48 cr gives interest coverage of 2.5 times. All of that reads as an ordinary manufacturer. The maturity schedule then shows Rs 250 cr falling due within twelve months against Rs 150 cr of cash and roughly Rs 110 cr of annual operating cash flow — the ratios were fine and the calendar was the constraint.
Pro tip — Ratios describe the size of a debt; the maturity table describes its urgency. Open the borrowings note, take the amount due within twelve months, and divide it by last year's operating cash flow. If that number is above one, the company is dependent on refinancing regardless of how comfortable every other ratio looks.
Warning — The most common error is taking only the 'long-term borrowings' line as total debt. Current maturities of long-term debt sit inside current liabilities, working capital facilities sit in short-term borrowings, and lease liabilities sit separately again. Miss them and gross debt can be understated by a third, which flows into every ratio you then compute. Build the figure from the borrowings note, not from one line on the face of the balance sheet.
Frequently asked questions
How do you calculate the interest coverage ratio?
Divide EBIT — operating profit, before interest and tax — by the interest expense for the same period. A result of 2.5 means operating profit is two and a half times the interest bill, so profit could fall roughly 60 per cent before the company stopped covering interest from operations. Take gross interest from the finance costs note rather than a figure netted against interest income, and check whether any interest has been capitalised into an asset under construction, because that portion never appears in the P&L.
Debt-to-equity vs net debt to EBITDA — which is better?
They measure different things. Debt-to-equity is structural: how the asset base was funded, split between lenders and owners. Net debt to EBITDA is a burden measure: how many years of operating earnings the borrowings represent. Net debt to EBITDA is generally the more useful of the two because its denominator is earnings rather than a historical book value, and it is what most loan covenants are written on — but it overstates capacity for capital-heavy businesses because it adds back depreciation.
What is a safe debt-to-equity ratio?
There is no level that is safe across sectors, because the ratio has to be read against how stable the operating profit underneath it is. A regulated utility with contracted revenue can carry leverage that would be untenable for a commodity producer whose realisations swing. What can be said mechanically is that above roughly 2.0 the business is financed mostly by lenders, so profit before tax becomes highly sensitive to both interest rates and any dip in demand.
What is the difference between gross debt and net debt?
Gross debt is total borrowings — long-term, short-term, current maturities of long-term debt and lease liabilities. Net debt subtracts cash and liquid investments from that. Net debt is the more realistic measure of the burden when the cash is genuinely surplus and unrestricted, but gross debt is what determines the interest bill, and cash that is pledged, held as a debt service reserve, or trapped in a subsidiary cannot legitimately be netted off.
Why does interest coverage fall before other debt ratios worsen?
Because it is the only one of them that compares a fixed obligation against current earnings. Principal is not due until its scheduled date, so a struggling company keeps its debt-to-equity ratio looking unchanged for a while. Interest, though, falls due every quarter irrespective of sales, so the moment operating profit weakens the coverage ratio moves. It is a live pressure reading rather than a balance sheet photograph.
Is a company with high debt always risky?
Not automatically — the risk depends on three things the debt figure alone does not show. How stable the operating profit is, because volatile earnings make any fixed obligation harder to carry. When the debt is due, because refinancing risk is about the calendar rather than the total. And what the borrowing paid for, since debt matched by capital expenditure is building an asset that will generate cash, while borrowing that funds operating losses has no such end point.
Do these debt ratios work for banks and NBFCs?
No. For a lender, borrowing is the raw material rather than a financing decision, so a bank's balance sheet is deliberately many times its equity and a debt-to-equity ratio around ten is ordinary rather than alarming. Interest coverage is meaningless when interest is the main cost of the business. Banks and NBFCs are assessed on capital adequacy against a regulated minimum, net interest margin, CASA mix, gross and net NPAs, and provision coverage instead.
