What Is Working Capital?

Working capital, also known as net working capital (NWC), is the difference between聽a company鈥檚 current assets, such as cash, accounts receivable (customers鈥 unpaid bills) and inventories of raw materials and finished goods, and聽its聽current liabilities, such as accounts payable. Net operating working capital is a measure of a company's liquidity and refers to the difference between operating current assets and operating current liabilities. In many cases these calculations are the same and are derived from company cash plus accounts receivable plus inventories, less accounts payable and less accrued expenses.

Working capital is a measure of a company's liquidity, operational efficiency and its short-term financial health. If a company has substantial positive working capital, then it should have the potential to invest and grow. If a company's current assets do not exceed its current liabilities, then it may have trouble growing or paying back creditors, or even go bankrupt.

Key Takeaways

  • A company has negative working capital If the ratio of current assets to liabilities is less than one.
  • Positive working capital indicates that a company can fund its current operations and invest in future activities and growth.
  • High working capital isn't always a good thing. It might indicate that the business has too much inventory or is not investing its excess cash.

The Formula for Working Capital

To calculate the working capital, compare a company's current assets to its current liabilities. Current assets listed on a company's balance sheet include cash, accounts receivable, inventory and other assets that are expected to be liquidated or turned into cash in less than one year. Current liabilities include accounts payable, wages, taxes payable, and the current portion of long-term debt. Current assets are available within 12 months. Current liabilities are due within 12 months.

The standard formula for working capital is current assets minus current liabilities.

Working capital that is in line with or higher than the industry average for a company of comparable size is generally considered acceptable. Low working capital may indicate a risk of distress or default.

Changes in Working Capital Affect a Company's Cash Flow

Most major new projects, such as an expansion in production or into new markets, require an investment in working capital. That reduces cash flow. But cash will also fall if money is collected too slowly, or if sales volumes are decreasing 鈥 which will lead to a fall in accounts receivable. Companies that are using working capital inefficiently can boost cash flow by squeezing suppliers and customers.
