About this tool

Working capital is the difference between current assets and current liabilities — it measures how much short-term financial cushion a company has. Positive working capital means the company can pay its bills for the next twelve months from what it already owns; negative working capital means it cannot, at least on paper. The figure matters because a profitable company can still run out of cash if its receivables come in slower than its payables go out.

Three ratios refine the picture. The current ratio (current assets ÷ current liabilities) is the broadest measure — above 1.0 is generally healthy, below 1.0 is a warning. The quick ratio, also called the acid test, subtracts inventory from current assets before dividing, because inventory is the hardest current asset to turn into cash quickly — a ratio above 1.0 means the company can pay its short-term debts without selling inventory. The cash ratio uses only cash and equivalents, the most conservative measure.

None of these ratios tell the whole story alone. A supermarket chain routinely runs on negative working capital because it sells goods before paying suppliers — that is a business model, not a crisis. A construction company with a current ratio of 3.0 may still be illiquid if most of its current assets are receivables that will not arrive for months. Use the ratios as a starting point, not a verdict, and compare them with industry benchmarks rather than with a universal rule.

The formula

Net working capital = current assets − current liabilities. Current ratio = CA / CL. Quick ratio = (CA − inventory) / CL. Cash ratio = cash / CL.

Frequently asked questions

What is a good current ratio?

Generally above 1.0, and in many industries between 1.5 and 2.0. But it depends on the business — retailers often operate below 1.0 because they collect before they pay.

What is the quick ratio?

Current assets minus inventory, divided by current liabilities. It excludes inventory because it may take time to sell — the ratio shows whether the company can pay its debts from assets that are already or nearly liquid.

Can working capital be negative?

Yes. Some business models run on negative working capital by design — for example, supermarkets receive cash from customers before paying suppliers. For most businesses, sustained negative working capital is a risk.

Does my data leave my browser?

No. All calculations run in JavaScript on your device. Nothing is stored or transmitted.

Is this enough for a financial analysis?

It is a starting point. A full analysis considers cash flow statements, debt maturity schedules, seasonality and industry benchmarks — none of which a single ratio captures.
