working capital

Imagine your month's near-term money: the cash and quick funds you can use soon, minus the bills coming due soon. If what is coming in shortly comfortably exceeds what you must pay shortly, you have breathing room; if not, you are squeezed. For a business, that breathing room has a name — working capital.

Working capital is simply current assets minus current liabilities. If a firm has 90,000 of current assets (cash, receivables, inventory) and 60,000 of current liabilities (payables, short-term debt), its working capital is 30,000. A positive figure means the short-term resources more than cover the short-term obligations, suggesting the business can pay its near-term bills without scrambling. A negative figure (current liabilities exceeding current assets) is a warning sign that the company may struggle to meet obligations as they fall due — though a few efficient businesses, like some supermarkets that collect cash instantly but pay suppliers later, run on negative working capital quite deliberately.

Working capital matters because it is a quick read on short-term financial health and on how much of a firm's money is tied up in day-to-day operations. Managers watch it closely: too little and the firm risks running short of cash; too much can mean lazy resources, with cash needlessly trapped in excess inventory or uncollected receivables. The honest caveat is that the headline number hides quality. Working capital of 30,000 looks fine, but if most of the current assets are slow-moving inventory or doubtful receivables, the firm may be far less able to pay its bills than the figure suggests.
