Liquidity Analysis
Each dollar of current liabilities is backed by 1.69 dollars of current assets - $1,250,000 of net working capital in reserve. Obligations due within twelve months are comfortably covered, leaving margin to absorb slower collections or inventory write-downs while staying ahead of the 1.5× industry norm.
*Computed from the balance-sheet lines you enter as at the reporting date. Working capital ignores the timing of cash flows within the year; verify with receivables ageing and inventory notes in the annual report. Educational only, not investment advice.
The Twelve-Month Solvency Test Every Balance Sheet Faces
Working capital is the gap between what a company owns that turns into cash within twelve months and what it owes within twelve months. Net working capital is that gap in dollars; the working capital ratio - current assets divided by current liabilities - expresses the same test as a coverage multiple. A ratio of 2.0 says each dollar of near-term obligations is backed by two dollars of cash, receivables and inventory; a negative working capital position says short-term debts already outrun short-term assets and survival depends on collections, supplier terms or a credit line arriving on schedule. For Australian investors the metric earns its keep every reporting season. Half-year and full-year balance sheets publish the exact lines this calculator consumes - cash, trade debtors, inventories against payables, short-term borrowings and accruals - and the verdicts differ sharply by sector. Woolworths and Coles run ratios below 1.0 deliberately because customers pay before suppliers do, while builders and contractors with the same reading have historically been insolvencies in progress. The number only means something next to its industry norm and its own trend, which is exactly what the benchmark slider and the dollar readout here are designed to expose.
Building the Ratio From the Balance-Sheet Lines
The calculator reconstructs the two aggregates from their components rather than asking for totals. Current assets sum cash and equivalents, trade receivables, inventories and other current assets; current liabilities sum trade payables, short-term borrowings and other current liabilities such as accruals and the income tax liability. Net working capital is current assets minus current liabilities, and the working capital ratio divides the same two totals - so a $1,220,000 asset base against $560,000 of obligations produces $660,000 of working capital and a 2.18 ratio. Two derived readouts add context. Liability coverage restates the ratio as a percentage - 218% coverage in that example - which is often easier to communicate. The benchmark gap compares your ratio against the industry figure you set, expressing how far above or below the sector norm the company sits; a 2.18 reading against a 1.5 norm is 45% ahead. The verdict bands follow standard screening practice: below 1.0 is at risk, 1.0-1.5 is tight, 1.5-3.0 is healthy, and above 3.0 suggests capital sitting idle that could fund dividends or growth.
Expert Insights
Negative Working Capital Can Be a Business Model
Supermarkets, hardware chains and subscription businesses routinely run ratios below 1.0 without distress: customers settle immediately while supplier invoices stretch out 60 to 90 days, so growth generates free financing rather than consuming cash. Woolworths and JB Hi-Fi have operated this way for decades. The red flag is not the sub-1.0 reading itself but a negative-reading company that lacks pricing power or supplier leverage - context the industry slider is there to supply.
In Construction, the Reading Predicts the Headlines
Australia's builder insolvencies follow a balance-sheet script: progress claims sit in receivables, retention monies are withheld, and trade payables pile up between projects - leaving negative working capital long before the administrator arrives. When a contractor's ratio slips under 1.0 while receivables balloon faster than revenue, the market is being warned. Treat the trend across successive half-year reports as the signal, and the dollar shortfall as its size.
Watch the Composition, Not Just the Total
Two companies can both show a 1.8 ratio with entirely different quality: one holds mostly cash, the other mostly inventory that may need discounting to clear. A rising inventory line against flat sales hints at slowing demand; receivables growing faster than revenue hints at stretched collection terms. Read the notes to the accounts - debtor ageing and inventory write-downs - before trusting any single ratio, however healthy it looks.
Actionable Tips

Pull the Lines Straight From the Balance Sheet
Every ASX annual report and half-year accounts list current assets and current liabilities in the balance sheet, with the component lines in the notes. Enter them as reported rather than adjusting optimistically - the point of the exercise is the company's own arithmetic, not yours. Ten minutes per stock each reporting season keeps a working-capital watchlist current across your whole portfolio.

Set the Benchmark to the Sector, Not a Universal Rule
The healthy reading varies enormously: grocers and retailers cluster near 0.8-1.1, diversified industrials near 1.5-2.0, miners swing with commodity cycles, and professional-services firms run lean because inventory barely exists. Set the industry slider to the sector's typical range before reading the benchmark gap - a 1.2 ratio is alarming for a manufacturer and unremarkable for a supermarket.

Pair It With the Quick Ratio for Quality
The working capital ratio counts inventory at full value; the quick ratio on this site strips it out to test whether the most liquid assets alone cover obligations. Run both: when the two diverge sharply, inventory is doing the heavy lifting and deserves scrutiny - check turnover and write-down history before accepting the healthier headline number as the whole story.
Real-World Examples
Marcus Screened a Builder Before the Collapse
Marcus liked a small-cap contractor's order book but ran the balance sheet through this tool first: $560,000 of current assets against $690,000 of current liabilities, with receivables up 40% in six months. The negative working capital and the benchmark gap against its 1.3 sector norm were enough to pass. Eighteen months later the company entered administration - the ratio had flagged it two reporting periods early.
Elena Nearly Dumped a Supermarket Over a Sub-1.0 Ratio
Elena's screen flagged a grocer at 0.85 - 'at risk' by the standard bands - and she nearly sold. Setting the industry benchmark to the retail norm of 0.8 reframed it: the company collected from customers daily while paying suppliers on 75-day terms, so negative working capital was the engine of expansion, not a warning. She held, and the stock compounded while the supplier float funded new stores.
Raj Tracked a Miner Through the Cycle
Raj watched an iron ore producer's working capital swing from $900 million positive to near zero across a price downturn as receivables stretched and inventory of unsold stock built up. The dollar readout - not just the ratio - showed him the squeeze was worth hundreds of millions. He trimmed before the dividend was cut, using the working capital line as his early-warning dashboard rather than waiting for the payout announcement.
Glossary of Terms
