Working Capital: Full Guide for Indian Investors

Most beginners look at profit first. It is the headline everyone watches. But some businesses do not fail because they stop making sales — they fail because their cash gets trapped in unpaid invoices and unsold inventory while the bills keep arriving.

You see profit rising. The stock looks cheap. Then a quarter later the company quietly raises debt because its customers have not paid. That is the working-capital trap.

Here is why it fools people. Profit shows up in the profit-and-loss statement, in plain view. But unpaid invoices and unsold stock sit further away, in the balance sheet, where fewer beginners look. Working capital is the simplest way to check whether the profit is actually turning into cash.

Most beginners also read working capital as a simple positive-is-good, negative-is-bad signal. That misses the point. Hindustan Unilever — the fast-moving consumer goods (FMCG) giant behind Lux, Surf Excel and Dove — runs a structurally negative operating working capital, with its suppliers effectively funding the business, and still earns one of the highest returns on capital in the Indian market.

What working capital actually measures

Picture a friend running a small kirana store. To stock his shelves he buys ₹3 lakh worth of goods from a wholesaler on thirty-day credit. He sells most of it in three weeks and collects ₹4 lakh in cash from customers paying upfront.

When the wholesaler's bill comes due, he pays from the cash already sitting in the till. The supplier's credit financed his inventory; the customers paid before he had to. His own money was barely involved.

A listed company works the same way at a much larger scale. Current assets are the things expected to turn into cash within a year: cash itself, short-term investments, money owed by customers, and inventory waiting on the shelves.

Current liabilities are the bills due within a year: money owed to suppliers, short-term loans, and the portion of long-term debt that has to be repaid in the next twelve months.

The difference between the two is the working capital. A large positive number means the company has a thick liquidity cushion. A small or negative number means it leans on supplier credit and customer pre-payments to bridge the gap.

Why this matters comes down to one word: survival. A business can be deeply profitable on paper and still go under if it cannot meet next month's bills. Working capital is the simplest reading of whether that risk is real.

How to calculate working capital, with real Indian examples

The formula in textbook form is simple.

Working capital = Current assets − Current liabilities

Many analysts prefer the ratio form, which scales across companies of different sizes.

Current ratio = Current assets ÷ Current liabilities

Here is the same idea drawn as two stacks. Imagine a company with these (illustrative) balances:

Before the examples, hold onto the distinction from the top of this article. The same topic answers four different questions, and mixing them up is where most beginners go wrong.

Three Indian names show how different the answer can look. The figures below are approximate, taken from FY25 (the year ended March 2025) balance sheets on a consolidated basis, and are meant to illustrate the pattern rather than serve as a research note. Always confirm the latest numbers in the company's own annual report.

Sun Pharma carries roughly ₹52,000 crore of current assets against about ₹18,000 crore of current liabilities. Working capital is a large positive figure of around ₹34,000 crore, and the current ratio is close to 2.9.

The business holds genuine inventory and extends credit to customers, and it keeps a thick cushion on top. This is the classic "comfortable" balance sheet.

Tata Steel runs around ₹68,000 crore of current assets against roughly ₹86,000 crore of current liabilities. Here working capital is actually negative — a gap of about ₹18,000 crore — and the current ratio is near 0.8.

But this is not the "good" kind of negative. A large slice of those current liabilities is short-term borrowing, so the gap reflects how the company is financed, not customers paying early. Steelmaking also locks up huge amounts of raw material and finished inventory.

Hindustan Unilever is the most interesting case. Its current assets sit near ₹22,000 crore against current liabilities of about ₹16,500 crore, so its accounting working capital is positive and the current ratio is roughly 1.3 — helped by a cash-and-investments pile of around ₹11,000 crore.

Yet strip out that cash and look only at the trade cycle, and HUL's operating working capital is negative: it pays suppliers far later than its customers pay it. The headline number and the trade cycle tell two different stories, and both are true.

Three companies, three different shapes of the same balance-sheet line, all listed on the National Stock Exchange (NSE), India's largest exchange. A thick positive cushion, a debt-driven shortfall, and a brand so dominant its suppliers fund its trade cycle.

One habit to build from the start. Some screeners report only the current ratio, others show the absolute figure. Pull both for the names you study; the ratio normalises across sizes, but the absolute number tells you how much liquidity is actually on the table.

What healthy working capital looks like across Indian sectors

There is no single safe figure that works for every business. A current ratio of 1.0 is normal for an FMCG company and worrying for a capital-goods maker. The right anchor is always the sector.

The picture below is a rough, illustrative guide to how much cash different sectors tie up in their operating cycle. Treat it as a starting intuition, not a set of benchmarks — real ratios vary widely even within a sector.

Hindustan Unilever, ITC, Nestle India and IndiGo sit at the top of that list for a reason. Distributors pay upfront for FMCG stock, and airline tickets clear the bank account before the flight takes off. Suppliers are paid weeks later, so the trade cycle funds the business and lifts return on capital.

IT services like TCS and Infosys, and paint majors like Asian Paints, carry little inventory and collect quickly, so their working capital is light. Pharma, auto and cement names like Sun Pharma, Maruti and UltraTech need real raw material, finished goods in the warehouse and credit to dealers, so they tie up a few months of cash — the natural working state of the industry.

Capital goods companies like ABB India and Siemens, and engineering, procurement and construction (EPC) firms like L&T, lock cash into multi-year projects. Their current ratio is often only moderate, though, because large customer advances and supplier payables sit on the other side — which is exactly why you judge the cash cycle, not just the ratio.

Real estate and infrastructure builders can trap the most cash of all, in unsold inventory and slow receivables. Their current ratios vary widely; a high one built on flats no one is buying is far weaker than a moderate one backed by cash.

So the anchor question is never "is the current ratio above 1.5." It is "is this number reasonable for this sector, and is the composition of current assets clean."

Here is the same idea as a quick-reference table.

The cash conversion cycle — the version that actually matters

A snapshot of working capital tells you how things look on March 31. The cash conversion cycle tells you how long money is actually trapped inside the business across the year.

It is built from three numbers, each taken from the financial statements.

Inventory days = how long stock sits on the shelves before being sold.

Receivable days = how long it takes customers to pay after the sale.

Payable days = how long the company takes to pay its own suppliers.

Cash conversion cycle = Inventory days + Receivable days − Payable days

The number is the count of days cash is locked up between paying suppliers and getting paid by customers. A shorter cycle means cash returns faster and can be redeployed into growth without borrowing.

Hindustan Unilever is the textbook example. Inventory turns over in roughly 60 days and customers pay in about 20 days, but suppliers are paid only after around 150 days. The cycle works out to roughly negative 70 days.

In other words, the supplier is financing the business while HUL earns operating profits on cash it has not yet paid out. (These day-counts are approximate, drawn from recent reported figures, and shift a little each year.)

Sun Pharma sits at the other end of the same league. Cash can stay locked up in stock and customer credit for well over a hundred days at a time — a long operating cycle, but a normal one for a global generics maker that holds large inventory and gives wide credit.

The lesson is straightforward. Always pull all three components, and let the trend over five years tell the story. A flat or shrinking cycle with rising sales is one of the cleanest signs of a high-quality business. A rising cycle without rising sales is one of the cleanest early warnings that something is wrong.

This single reading cuts through a lot of the false comfort the headline current ratio gives. Two companies can both show a current ratio of 1.8 — one quietly building a cash machine, the other slowly drowning in unsold inventory.

How to actually use working capital in your research

Once the framework clicks, the workflow is short — maybe ten minutes per company. Run these five steps in order.

1. Check the sector first. Pin down what the business actually does. FMCG, airlines and quick-service restaurants naturally run a current ratio near or below 1. Capital goods and construction sit higher. Compare to peers, not to a textbook number.
2. Read the current ratio in context. Place the company next to three or four close peers. A 1.2 ratio is normal for an FMCG name and uncomfortably tight for a cement company. The sector decides the verdict.
3. Look at the five-year trend. A single year of high working capital can be a one-off, often a big project or a planned inventory build. A current ratio drifting up year after year usually means receivables are growing faster than sales — rarely a good story.
4. Calculate the cash conversion cycle. Work out inventory days, receivable days and payable days from the latest annual report. The direction of the cycle over five years matters far more than the absolute number.
5. Check the composition. Read the notes to the balance sheet. If a large chunk of receivables is over 180 days old, or inventory has grown without matching sales, the headline number is lying. Quality of current assets matters as much as quantity.

A useful Saturday-morning exercise for a beginner is to pick five companies from completely different sectors. Note the current ratio, the cash conversion cycle, the five-year trend, and the composition of receivables for each.

The pattern jumps out fast. The genuine compounders with negative or shrinking cycles, the appropriately funded industrials with stable ratios, and the troubled names with rising cycles and ageing receivables sort themselves into three obvious groups.

Repeat the exercise each quarter as fresh results come in. Over a year, working capital stops being a number on a screen and becomes the way you actually see whether a business is generating cash or quietly burning it.
