Working capital is the amount of a company's current assets minus the amount of its current liabilities. For example, if a company's balance sheet dated June 30 reports total current assets of $323,000 and total current liabilities of $310,000 the company's working capital on June 30 was $13,000. If another company has total current assets of $210,000 and total current liabilities of $60,000 its working capital is $150,000.
