Working Capital
Key Takeaways
- Working capital = Current Assets - Current Liabilities
- Positive working capital means a company can cover its short-term obligations
- Too much working capital may indicate inefficient use of assets
- Working capital management directly impacts cash flow
Definition
Working capital is a measure of a company's short-term financial health and operational efficiency, calculated as current assets minus current liabilities. It represents the amount of liquid resources available to fund day-to-day operations after meeting short-term obligations.
Current assets include cash, accounts receivable, inventory, and other assets expected to be converted to cash within one year. Current liabilities include accounts payable, short-term debt, accrued expenses, and other obligations due within one year.
Positive working capital indicates a company has sufficient short-term assets to cover its short-term obligations. Negative working capital means current liabilities exceed current assets, which can signal liquidity problems — though some businesses like Amazon operate successfully with negative working capital by collecting from customers before paying suppliers.
How It Works
Working Capital = Current Assets - Current Liabilities. The current ratio (Current Assets / Current Liabilities) expresses the same concept as a ratio. A current ratio above 1.0 means positive working capital.
Working capital management involves optimizing the balance between receivables, inventory, and payables. Companies aim to collect receivables quickly, turn inventory efficiently, and extend payables as long as commercially acceptable. The cash conversion cycle measures how many days it takes to convert working capital investments into cash.
Changes in working capital directly affect cash flow. An increase in accounts receivable or inventory uses cash. An increase in accounts payable provides cash. These working capital changes appear in the operating cash flow section of the cash flow statement.
Example
Walmart (WMT) reported current assets of $75 billion (including $9B cash, $7B receivables, $57B inventory) and current liabilities of $92 billion (including $54B accounts payable, $13B accrued liabilities). Working capital = $75B - $92B = -$17 billion. Despite negative working capital, Walmart operates successfully because it collects cash from customers immediately while paying suppliers 30-60 days later. This negative working capital actually generates cash for the business — a hallmark of companies with strong bargaining power over suppliers.
Why It Matters
Working capital management is critical to a company's survival. Even profitable companies can go bankrupt if they cannot meet short-term obligations. Monitoring working capital trends helps investors identify potential liquidity problems before they become crises.
For investors, working capital efficiency reveals management quality. Companies that manage working capital well — collecting receivables promptly, maintaining lean inventory, and negotiating favorable payment terms — generate stronger free cash flow and require less external financing.
