Working Capital Formula: What Is It?

What is the working capital formula?

Working capital is crucial for any business, and using the working capital formula is a simple way to see how a company is performing. Before we look at the formula, let’s delve into the subject of working capital.

Definition of working capital

Businesses need working capital to pay employees, as well as cover ongoing expenses and operating costs, such as paying rent and utilities. Working capital is calculated by subtracting current liabilities from current assets

When you understand working capital (sometimes called ‘net working capital’), you can plan for sustainable growth and meet future expenses. 

The components of working capital

The components used to calculate working capital are current assets and current liabilities: 

Current Assets: This includes cash and cash equivalents, marketable securities, inventory and accounts receivable. Assets that a company owns that can be converted into cash within 12 months also fall under this category.

Current Liabilities: Money the business owes in the form of the accounts payable, accrued expenses, and short-term loans that are due within a year fall under this category. Long-term debt is not classified as a current liability. 

Calculating the working capital ratio

Here’s the net working capital formula used to calculate the working capital ratio:

 Working Capital = Current Assets – Current Liabilities

This working capital ratio formula shows how much short-term liquid assets you have after paying off the short-term liabilities. It measures short-term liquidity and is used in financial modelling, financial analysis, and cash flow management. This formula is considered to be the broadest, since it includes all the accounts. 

There’s another formula that’s not as broad and only includes three accounts:

 Net Working Capital = Accounts Receivable + Inventory – Accounts Payable

Example of net working capital

Here’s an example of the balance sheet that will indicate how to derive the net working capital (NWC):

Current Assets

Cash: $30,000

Inventory: $50,000

Accounts Receivable: $25,000

Total: $105,000

 Current Liabilities

Accrued Liabilities: $20,000

Accounts Payable: $25,000

Short-term Borrowings: $3,000

Total: $48,000

 Using the working capital formula, we subtract current liabilities from current assets:

Working Capital = $105,000 (current assets) – $48,000 (current liabilities) = $57,000

 If we use the other working capital formula, which is sometimes used by business lenders, working capital will be:

 Net Working Capital = $25,000 (Accounts Receivable) + $50,000 (Inventory) – $25,000 (Accounts Payable) = $50,000

Positive working capital

If a company has positive working capital, it’s a good sign. It shows that the business is doing well and has enough liquid assets to pay any short-term obligations such as short-term debt and bills. The example above shows that the company has a positive working capital.

Here’s another example that shows the positive working capital in a balance sheet. 

The ABC company has the following current assets and liabilities:

Current Assets

Cash: $30,000

Inventory: $ 20,000

Accounts Receivable: $5,000

Total: $ 55,000

Current Liabilities

Accrued Liabilities: $22,000

Accounts Payable: $25,000

Short-term Borrowings: $3000

Total: $50,000

In this example, Net Working Capital (NWC) = $55,000 (Total Assets) $50,000 (Current Liabilities) = $5,000.

Negative working capital

Negative working capital indicates that a company is not using current or fixed assets effectively. Here’s an example:

Current Assets

Cash: $10,000

Inventories: $ 20,000

Accounts Receivable: $5,000

Total: $35,000

Current Liabilities

Accrued Liabilities: $15,000

Accounts Payable: $25,000

Short-term Borrowings: $5000

Total: $45,000

In this example, Net Working Capital (NWC) = $35,000 (Total Assets) – $45,000 (Current Liabilities) = – $10,000.

This situation will eventually damage the credit rating of the business, especially if it ends up borrowing more money or when it’s late in paying suppliers and creditors.

In some cases, negative working capital is perfectly okay. For example, high-volume retail businesses such as Woolworths and Coles. Although they may have negative working capital, they can raise large amounts of capital to cover temporary shortfalls. This is possible because of the quick turnover rates of the vast inventory that they hold in their stores. They are in a position where they can sell products before they need to pay the suppliers and vendors. So while they might have negative working capital at times (as a result of their accounts payable), they are constantly selling inventory to boost their cash. 

In contrast, companies that manufacture things like machinery and equipment need large amounts of working capital as there are large time gaps between creating products and receiving revenue from selling them. These types of issues can be analysed using the working capital formula.

Unsecured business loans are one option to overcome negative working capital.
