Working capital is the capital of a business which is used in its day-to-day trading operations, calculated as the current assets - the current liabilities.

Working capital, also known as net working capital, is the difference between a company's current assets, like cash, accounts receivable (customers' unpaid bills) and inventories of raw materials and finished goods, and its current liabilities, like accounts payable.
