What Is Working Capital?
Working capital is the difference between a company's current assets and its current liabilities — the short-term capital available to fund day-to-day operations. Positive working capital means current assets exceed current liabilities; negative working capital means the reverse.
What working capital is and why it matters
Working capital measures whether a business has enough short-term resources to cover its short-term obligations and keep operating smoothly. It's tied up in the operating cycle — cash becomes inventory, inventory becomes receivables, and receivables become cash again — so managing it is really about managing that cycle's timing. Too little working capital risks missing payments and stalling operations; too much can mean cash is sitting idle in inventory or receivables instead of being put to work. The working-capital ratio (current assets ÷ current liabilities, i.e. the current ratio) expresses the same idea as a ratio rather than a dollar amount.
A worked example
A company has current assets of $180,000 (cash $40,000, receivables $70,000, inventory $70,000) and current liabilities of $110,000 (payables $60,000, short-term debt $50,000). Working capital = $180,000 − $110,000 = $70,000. That $70,000 cushion funds operations between paying suppliers and collecting from customers. The current ratio is $180,000 ÷ $110,000 ≈ 1.6, confirming comfortable short-term coverage.
How firms handle it today
Firms monitor working capital from reconciled balance-sheet figures and advise clients on improving it — accelerating collections, managing inventory, and timing payables — to free up cash.

FAQ
What's the working capital formula?
Current assets minus current liabilities.
Is negative working capital always bad?
Not always — some efficient businesses (like fast-turnover retailers) operate with negative working capital by collecting from customers before paying suppliers. For most, though, negative working capital signals liquidity risk.
What's the difference between working capital and cash flow?
Working capital is a snapshot of short-term resources at a point in time; cash flow is the movement of cash over a period.
