Every business needs two types of money — money to buy long-term assets like factories and machinery (CAPEX), and money to keep the business running day to day. This second type is called Working Capital. Understanding it is essential for anyone analysing a company’s financial health.
Working Capital — Meaning
Working Capital is the money a company needs to fund its day-to-day operations — paying suppliers, managing inventory, collecting payments from customers, and meeting short-term obligations.
In simple terms: working capital is the cash tied up in the operating cycle of a business — from buying raw materials, converting them into products, selling them, and finally collecting payment.
Working Capital Formula
Working Capital = Current Assets − Current Liabilities
Where:
- Current Assets = assets expected to be converted to cash within 12 months (inventory, trade receivables, cash, short-term investments)
- Current Liabilities = obligations due within 12 months (trade payables, short-term borrowings, accrued expenses)
How to Calculate Working Capital — Example
Company ABC — Balance Sheet as of March 31, 2025:
| Current Assets | ₹ crore | Current Liabilities | ₹ crore |
|---|---|---|---|
| Cash & Equivalents | 200 | Trade Payables | 300 |
| Trade Receivables | 400 | Short-term Borrowings | 150 |
| Inventory | 350 | Accrued Expenses | 100 |
| Other Current Assets | 50 | Other Current Liabilities | 50 |
| Total Current Assets | 1,000 | Total Current Liabilities | 600 |
Working Capital = ₹1,000 − ₹600 = ₹400 crore
This company has ₹400 crore of working capital — meaning it has more than enough short-term assets to cover its short-term obligations.
Positive vs Negative Working Capital
| Working Capital | What It Means | Examples |
|---|---|---|
| Positive (Current Assets > Current Liabilities) | Company can meet short-term obligations comfortably | Most manufacturing, pharma, FMCG companies |
| Zero (Current Assets = Current Liabilities) | Tight but manageable — no buffer | Lean operations with efficient cash cycles |
| Negative (Current Assets < Current Liabilities) | May struggle to pay short-term dues — but can be intentional in some models | Retail (Walmart, D-Mart), subscription businesses |
Important: Negative working capital is not always bad. Companies like D-Mart (Avenue Supermarts) run negative working capital deliberately — they collect cash from customers immediately but pay suppliers after 30–60 days. This means suppliers are essentially financing D-Mart’s operations — a sign of extreme business strength, not weakness.
Components of Working Capital
Current Assets (what you own short-term):
- Cash and Cash Equivalents — most liquid, immediately available
- Trade Receivables (Debtors) — money owed by customers for goods/services delivered
- Inventory — raw materials, work-in-progress, finished goods
- Short-term Investments — liquid mutual funds, T-Bills held temporarily
- Prepaid Expenses — expenses paid in advance (insurance, rent)
Current Liabilities (what you owe short-term):
- Trade Payables (Creditors) — money owed to suppliers for goods received
- Short-term Borrowings — bank overdrafts, working capital loans
- Accrued Expenses — expenses incurred but not yet paid (salaries, utilities)
- Advance from Customers — payment received before delivering goods
- Current portion of Long-term Debt — loan instalments due within 12 months
Working Capital Cycle (Operating Cycle)
The working capital cycle shows how long it takes a company to convert its investments into cash:
Raw Material Purchase → Production → Finished Goods → Sale → Cash Collection
The shorter the working capital cycle, the better — the company needs less cash tied up in operations at any given time.
| Metric | Formula | What It Measures |
|---|---|---|
| Inventory Days | Inventory / (COGS ÷ 365) | Days inventory is held before sale |
| Debtor Days (DSO) | Receivables / (Revenue ÷ 365) | Days to collect payment from customers |
| Creditor Days (DPO) | Payables / (Purchases ÷ 365) | Days taken to pay suppliers |
| Cash Conversion Cycle | Inventory Days + Debtor Days − Creditor Days | Net days cash is tied up in operations |
Lower Cash Conversion Cycle = less working capital needed = more Free Cash Flow.
Working Capital and Free Cash Flow
Working capital directly impacts Free Cash Flow (FCF). When working capital increases (e.g. inventory builds up or customers take longer to pay), cash is consumed — reducing FCF even if PAT looks healthy.
FCF = Operating Profit + Depreciation − Tax − CAPEX − Increase in Working Capital
This is why a company can show rising profits but falling cash — if working capital is expanding faster than profits. Always check the working capital trend alongside EBITDA and PAT.
Working Capital Ratios — Key Metrics
1. Current Ratio
Current Ratio = Current Assets / Current Liabilities
Measures ability to pay short-term obligations. A ratio above 1.5 is generally comfortable; below 1.0 means current liabilities exceed current assets.
2. Quick Ratio (Acid Test)
Quick Ratio = (Current Assets − Inventory) / Current Liabilities
More conservative than current ratio — removes inventory (least liquid current asset). Above 1.0 is considered safe.
3. Working Capital Turnover
Working Capital Turnover = Revenue / Working Capital
Higher is better — shows how efficiently the company uses working capital to generate revenue.
Working Capital by Industry — What’s Normal?
| Industry | Typical Working Capital | Why |
|---|---|---|
| Manufacturing (Auto, Engineering) | High positive | Large inventory + long debtor cycles |
| FMCG (HUL, Nestle) | Low positive / near zero | Fast inventory turnover, strong supplier terms |
| Retail (D-Mart, Reliance Retail) | Negative | Immediate cash sales, delayed supplier payments |
| IT Services (TCS, Infosys) | Low positive | Minimal inventory, service-based model |
| Pharma (Sun Pharma, Cipla) | High positive | Large inventory requirements, regulatory holds |
| Infrastructure / Capital Goods | Very high positive | Long project cycles, milestone-based billing |
Working Capital and ROCE
Working capital is part of Capital Employed — the denominator in ROCE calculation. Companies that efficiently manage working capital (keeping it lean) have a lower Capital Employed for the same revenue, which directly improves ROCE.
This is one reason why asset-light businesses with negative or very low working capital — like D-Mart or Zomato — can generate exceptional ROCE despite seemingly thin margins.
Working Capital Management — What Good Looks Like
When analysing a company’s working capital management, look for these positive signs:
- Falling debtor days — customers paying faster
- Rising creditor days — company getting better supplier terms (paying later)
- Stable or falling inventory days — efficient stock management
- Shrinking Cash Conversion Cycle — less cash tied up in the operating cycle
- Working capital stable as % of revenue — not growing faster than the business
Red flags in working capital:
- Rapidly rising receivables without matching revenue growth — customers not paying, possible bad debts
- Inventory ballooning — goods not selling, potential write-offs
- Working capital loan (CC limit) growing every year — company funding operations through short-term debt
Key Takeaways
- Working Capital = Current Assets − Current Liabilities
- It represents the cash tied up in day-to-day business operations
- Positive working capital = buffer to meet short-term obligations; negative can be strength in retail models
- The Cash Conversion Cycle measures how long cash is tied up — shorter is better
- Rising working capital consumes cash and reduces Free Cash Flow even when profits are growing
- Efficient working capital management improves ROCE by reducing Capital Employed
Frequently Asked Questions (FAQ)
Q: What is working capital in simple terms?
Working capital is the money a company needs to run its day-to-day operations — paying suppliers, holding inventory, and collecting payments from customers. It is calculated as Current Assets minus Current Liabilities. A positive working capital means the company has more short-term assets than short-term obligations.
Q: What is the working capital formula?
Working Capital = Current Assets − Current Liabilities. Current Assets include cash, receivables, and inventory. Current Liabilities include trade payables, short-term borrowings, and accrued expenses. Both figures are found on the company’s balance sheet.
Q: Is negative working capital bad?
Not always. Negative working capital means current liabilities exceed current assets. For most businesses this signals financial stress. However, for retailers like D-Mart or Reliance Retail, negative working capital is a sign of strength — they collect cash from customers immediately but pay suppliers after 30–60 days, meaning suppliers fund their operations.
Q: What is a good working capital ratio?
The Current Ratio (Current Assets ÷ Current Liabilities) is the most common working capital ratio. A ratio of 1.5 to 2.5 is generally considered healthy for most industries. Below 1.0 may indicate liquidity risk; above 3.0 may suggest inefficient use of assets. Always compare within the same industry.
Q: How does working capital affect Free Cash Flow?
An increase in working capital consumes cash — reducing Free Cash Flow. For example, if a company’s inventory increases by ₹100 crore, that cash is tied up in stock and not available for other uses. This is why a company can report rising profits but declining cash — if working capital expands faster than profits.
Q: What is the Cash Conversion Cycle?
The Cash Conversion Cycle (CCC) = Inventory Days + Debtor Days − Creditor Days. It measures the number of days cash is tied up in a company’s operations. A lower or negative CCC means the business collects cash before it has to pay suppliers — a very capital-efficient model.
Q: Where can I find working capital data for Indian companies?
Working capital components (current assets and current liabilities) are available on any company’s balance sheet in their annual report. On Screener.in, you can find current ratio and working capital data under the balance sheet section. Tickertape and Moneycontrol also display these figures for all NSE/BSE listed companies.
Q: How does working capital relate to ROCE?
Working capital is part of Capital Employed — the denominator in the ROCE formula. Companies with lean or negative working capital have a lower Capital Employed for the same revenue, which boosts ROCE. This is why efficient working capital management is a key driver of superior returns on capital.
