Where it fits
Working capital is the difference between current assets and current liabilities, representing the short-term liquidity available to fund daily operations. This fundamental measure of financial health shows whether a company has sufficient resources to meet its near-term obligations and continue normal business activities.
The basic formula:
Working Capital = Current Assets - Current Liabilities
For example, a company with $500 million in current assets and $300 million in current liabilities has $200 million in working capital.
Components of working capital:
Current Assets (typically convertible to cash within one year):
- Cash and cash equivalents
- Accounts receivable
- Inventory
- Prepaid expenses
- Short-term investments
Current Liabilities (obligations due within one year):
- Accounts payable
- Short-term debt and current portion of long-term debt
- Accrued expenses (wages, taxes, interest)
- Deferred revenue
The cash conversion cycle measures working capital efficiency:
CCC = Days Inventory Outstanding + Days Sales Outstanding - Days Payables Outstanding
Shorter cycles mean cash is tied up for less time, improving liquidity and reducing financing needs.
Why working capital matters:
- Operational continuity: Adequate working capital ensures the business can pay suppliers and employees
- Growth capacity: Expanding operations requires investment in inventory and receivables
- Financial flexibility: Surplus working capital provides buffer against unexpected needs
- Creditworthiness: Lenders evaluate working capital when extending credit
Interpreting working capital levels:
- Positive working capital: Current assets exceed current liabilities—company can meet short-term obligations
- Negative working capital: Current liabilities exceed current assets—may signal financial stress
- Excessive working capital: May indicate inefficient use of resources that could be invested elsewhere
Negative working capital exceptions:
- Retailers: Collect cash immediately but pay suppliers later
- Subscription businesses: Deferred revenue creates current liabilities without cash outflow
- Fast-moving consumer goods: High inventory turnover reduces working capital needs
Working capital management strategies:
- Accelerate collections: Reduce days sales outstanding through better credit policies
- Optimize inventory: Balance stock levels against carrying costs
- Extend payables: Negotiate longer payment terms with suppliers when appropriate
- Cash forecasting: Anticipate seasonal fluctuations in working capital needs
Investors should monitor working capital trends over time. Deteriorating working capital may signal operational problems or aggressive growth that could strain liquidity, while improving working capital often indicates better operational efficiency.
