Working capital commonly means current assets minus current liabilities, subject to any specific definition used by a firm or transaction.
Definition
Working capital commonly measures short-term resources available after subtracting short-term obligations: current assets minus current liabilities. For an engineering firm, current assets may include cash, accounts receivable, and other amounts expected to turn into cash or be used soon; current liabilities may include payables, accrued payroll, and other near-term obligations. A sale agreement or lender may define an adjusted working capital measure with specific inclusions, exclusions, or a target level. Billing patterns, collections, seasonality, project activity, and accounting choices can all affect the reported amount. Owners use it to understand short-term liquidity and, in a transaction, to discuss how much operating capital stays with the business at closing. Working capital is not the same as cash flow, which measures movement over a period, or profit, which follows revenue and expense recognition. It also does not mean every current asset is readily available cash, since receivables may be delayed or disputed.
How owners use it
- Review current assets and liabilities together when assessing short-term resources and obligations.
- Identify transaction-specific adjustments before comparing a measured balance with a target.
- For example, $420,000 current assets - $310,000 current liabilities = $110,000 working capital.
- Monitor billing and collection timing because receivables affect the reported balance.
