What is Working capital?
Current assets minus current liabilities — the operating buffer the business runs on day-to-day.
Working capital is current assets minus current liabilities — the short-term operating buffer a business runs on day to day. It measures the cushion of liquid resources a company has after covering the obligations due within the year.
Positive working capital means a company can comfortably cover its near-term obligations from its current assets; negative or shrinking working capital can signal a cash crunch ahead. But context matters: some strong businesses deliberately run on negative working capital, collecting cash from customers before they have to pay suppliers — a sign of pricing power, not weakness. The revealing thing is usually the trend and the reason: working capital deteriorating because inventory and receivables are ballooning is a warning, while a stable or efficiently managed position is a sign of a healthy operating cycle.
Working capital is current assets minus current liabilities — the short-term cushion a business runs on. Positive means near-term bills are comfortably covered; a deteriorating one warns of a cash squeeze.
For example
A company with $30M of current assets and $20M of current liabilities has $10M of working capital — the operating buffer it runs on day to day.

Working capital matters because it's a quick read on short-term financial health and how efficiently a company manages its operating cycle. A comfortable, stable position means the business can meet its obligations without strain; a deteriorating one — especially driven by swelling inventory or receivables — warns of a cash squeeze the profit figures may not yet show. Changes in working capital also directly affect operating cash flow, which is why tracking it links the balance sheet to the cash a business actually generates.
⚠ Assuming negative working capital is always bad
Negative working capital can signal a cash crunch — but for some strong businesses it's a deliberate strength, meaning they collect from customers before paying suppliers, effectively being funded by their own operations. Treating negative working capital as automatically alarming misreads these cases. What matters is the trend and the cause, not the sign alone.
