Working capital definition and example
Working capital is defined as current assets minus current liabilities. For example, if a company has current assets of $90,000 and its current liabilities are $80,000, the company has working capital of $10,000.
Note that working capital is an amount. Some of the factors that determine the amount of working capital needed include:
- Whether or not a company needs to have an inventory of goods
- How fast customers pay for goods or services
- How fast the company must pay its suppliers
- The company's growth rate
- The company's profitability
- The company's ability to get financing
Working capital can be increased by:
- Profitable business operations
- Sale of long-term assets
- Long-term borrowings
- Investment by owners
Working capital can decrease from:
- Unprofitable business operations
- Purchasing long-term assets (without long-term financing)
- Repaying long-term debt
- Distributing cash to owners
Liquidity is having the money to pay the company's obligations when they are due. In other words, it is the company's ability to convert its current assets to cash so that the current liabilities can be paid when they come due. Liquidity is necessary for a company to continue its business operations.
Liquidity could increase by:
- Increasing working capital (see the above list for increasing working capital)
- Increasing the speed at which current assets are converted to cash
- Delaying the payment of current liabilities
- Delaying the payment of long-term liabilities
- Omitting the distribution of cash to owners
Liquidity could decrease from:
- A decrease in working capital (see the above list for decreasing working capital)
- Purchasing and/or producing too many items for inventory
- A slowdown in the speed at which current assets are converted to cash
- Paying current liabilities too soon
Working capital vs. liquidity
A retailer, distributor or manufacturer may have a large amount of working capital. However, if most of its current assets are in slow-moving inventory, the company may not have the liquidity to pay its obligations on the agreed upon due dates. Similarly, if a company is unable to collect its accounts receivable, it may not have the liquidity to pay its obligations.
In contrast, consider a company that sells popular products online and customers pay with bank credit cards or debit cards when they order. Further, the company's suppliers allow the company to pay 60 days after it purchases the products. This company may have very little in working capital, but it may have the liquidity it needs.
Financial ratios and other metrics
There are some financial ratios and metrics that are closely related to working capital and liquidity, such as:
- Amount of working capital
- Current ratio
- Quick ratio
- Accounts receivable turnover ratio
- Average collection period
- Inventory turnover ratio
- Days' sales in inventory
- Cash from operating activities
- Operating cash flow ratio
We will discuss and calculate each of these. We will also point out that if these metrics are calculated by using the amounts from a company's financial statements, the amounts are likely from the prior year. Further, the amounts reported on the financial statements are highly-summarized. Hence, some unusual transactions and amounts will likely be hidden or buried by the enormous number of normal transactions.
People within a company will have access to more current amounts and more detailed information that can be sorted, reviewed and analyzed. Therefore, people within a company will gain more insights from the detailed internal information than someone calculating financial ratios by using the amounts reported on the prior year's published financial statements.
Finding the root cause
It is also important to understand the root cause for a change in working capital and/or liquidity. In the case of a liquidity problem, you should "drill down" by asking "Why has liquidity decreased?" You may discover a decrease in the company's accounts receivable turnover rate and an increase in its average collection period. Next ask "Why is there a decrease in the turnover rate and the increase in the average collection period?" You may find that two large customers have slowed their remittances of the amounts they owe. That should lead to another question: "Why is Customer X not paying according to the agreed-upon terms?" The answers could range from the customer is having financial difficulty to the customer is not pleased with the company's products or service. That should lead to yet another "Why?" question. The goal is to get past the symptoms and get to the root cause.
Similarly, if the decreases in working capital and/or liquidity are due to unprofitable business operations, a person should also begin a series of "Why?" questions. The answers may lead to an urgent need for an immediate reduction in expenses lest the company is forced to stop operating. Eliminating operating losses is also important for ongoing relationships with lenders, suppliers, customers, employees, owners and more.
Cash is king
"Cash is king" is a popular phrase for several reasons. One reason involves liquidity: cash is necessary to meet Friday's payroll, to make a loan payment, to pay suppliers, to remit payroll taxes, etc.
Another reason for "cash is king" pertains to the accrual method of accounting. Under this generally required method of accounting, a company's financial statements will report revenues and the related receivables when they are earned (not when the customers' cash is received). Further, expenses and liabilities are reported when they are incurred (not when the cash is paid out). Because of the judgements used in determining when the revenues and expenses are reported on the income statement, there is a concern with this perceived "flexibility". With cash there are no judgments or estimates involved. The company either has the cash or it doesn't.
Fortunately, companies are required to include the statement of cash flows (SCF) whenever its financial statements are distributed. The SCF will report the major cash inflows and cash outflows during the same period as the income statement. The SCF also reconciles the change in a company's cash during the past year. Since liquidity involves cash, you will gain valuable insights by understanding the SCF.
Components of Working Capital
Working capital (also known as net working capital) is defined as current assets minus current liabilities. Therefore, a company with $120,000 of current assets and $90,000 of current liabilities will have $30,000 of working capital. A company with $100,000 of current assets and $100,000 of current liabilities has no working capital. As you can see, working capital is an amount even though it is usually discussed as part of financial ratios.
A major component of working capital is current assets. A shortened definition of current assets is: a company's cash plus its other resources that are expected to turn to cash within one year.
However, the following is a more complete definition:
Current assets include cash (which is not restricted for a long-term purpose) plus the company's other resources that will turn to cash or will be used up within one year (of the date shown in the heading of the balance sheet). However, in the rare situations when a company's normal operating cycle is longer than one year, the length of the operating cycle is used in place of one year for determining a current asset.
Examples of current assets (listed in the order they are expected to turn into cash) include:
- cash and cash equivalents
- temporary investments
- accounts receivable
- prepaid expenses
The other major component of working capital is current liabilities. A shortened definition of current liabilities is: a company's obligations that will be due within one year.
However, a more complete definition is:
Current liabilities are a company's obligations (that are the result of a past event) that will be due within one year of the balance sheet's date. However, in the rare situations when a company's normal operating cycle is longer than one year, the length of the operating cycle is used in place of one year for determining a current liability.
Examples of current liabilities include:
- loan principal amounts that will be due within one year
- accounts payable
- wages payable
- payroll taxes withheld from employees
- accrued expenses/liabilities (utilities, repairs, interest, etc.)
- customer deposits and deferred revenues
If there is assurance that a current liability will be replaced by a long-term liability, it should be reported as a long-term liability. (The reason is the liability will not be requiring the use of the company's working capital.)
For a complete understanding of working capital, current assets, and current liabilities, it is necessary to understand the term operating cycle. A company's operating cycle is the average amount of time it takes for the company's cash to be put into the business operations and then make its way back into the company's cash account. To illustrate, let's assume that a distributor of products experiences the following:
- It uses its cash to purchase inventory items
- It takes on average 120 days to get the items sold by offering credit terms of 30 days
- On average, the company receives the money from these customers 45 days after the sales occurred (even though the credit terms were 30 days)
With these conditions, the distributor's operating cycle is on average 165 days, as illustrated here:
Throughout this topic you should assume that the companies we are discussing have:
- operating cycles of less than one year
- insignificant amounts of supplies and prepaid expenses
