Changes in Working Capital: An Easy Walk Through

Equity Accounting, Financial Statements

Updated 5/29/2023

Changes in working capital help explain how a company uses its assets to generate growth. Some companies build up inventories, pay down liabilities, or extend their repayments to vendors to growt their cash flows. The better we understand how a company uses its assets and liabilities, the better we can predict changes in value.

Please read the page slowly and take your time as we work through the topic. Some of the info we will cover can be confusing, but it is important to understand.

Understanding the topic will give you a great insight into the company’s free cash flow, their use of the cash flow, and where it comes from in the process.

In today’s post, we will learn:

What Are Changes in Working Capital: A Definition
Differences Between Working Capital and Changes in Working Capital
What is Operating Working Capital?
Breaking Down the “Change” in Working Capital
How to Calculate Changes in Working Capital
Real-Life Examples of Changes in Working Capital

Let’s get started, shall we?

What Are Changes in Working Capital: A Definition

So what are changes in working capital, and what does it mean?

Working capital is not changes in working capital.

The simple definition of working capital is:

Current assets – current liabilities

Unfortunately, this is a little too simple, and what we are looking for is the how and why of working capital.

According to Investopedia:

“Working capital is the difference between a company’s current assets, such as cash, accounts receivable (customers unpaid bills), and inventories of raw materials and finished goods. And its current liabilities, such as accounts payable.

Working capital measures a company’s liquidity, operational efficiency, and short-term financial health. If a company has substantial 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 bankrupt.”

That explains what working capital is and how it works to help a company grow nicely and tidy.

However, we need to look beyond the accounting standpoint and understand what the “change” in changes in working capital means.

Beyond a formula or equation defining working capital, the important issue remains what the change part means and how to interpret the changes and use those changes in valuing companies.

Differences between Working Capital and Changes in Working Capital

Remember that

working capital = current assets – current liabilities.

Working capital is a balance sheet definition that only gives us a value at a certain time.

Changes in working capital are an idea that lives in the cash flow statement.

Companies need working capital to survive and continue their operations; it is a necessary ingredient and remains the real reason for working capital, its raison d’etre.

Constantly looking at your balance sheet to determine your current assets minus your current liabilities makes little sense as a business owner.

key takeaways from changes in working capital

Changes in working capital will help you determine where Microsoft is in its working capital cycle. Companies will try to shorten their working capital cycle by collecting receivables sooner or extending accounts payable.

This cycle is what all companies strive to shorten instead of looking at the balance sheet definition, which defines only one certain point in time.

What is Operating Working Capital?

When discussing working capital, we need to determine the capital needs of operating the business and the business cycle.

All companies strive to shorten their business cycle by collecting their receivables sooner or extending their accounts payable. This ebb and flow of their business cycle give them more “cash” to operate their company.

When looking at the working capital needs, we need to consider only those items that affect their operational needs.

We could also refer to this as non-cash working capital because the company’s current assets include cash, which we need to exclude. After all, non-cash doesn’t drive Visa.

Let’s take a look at an actual cash flow statement from Amazon (AMZN) to use as an example of how we break the changes all down.

For the remainder of the post, the section we will focus on is the Changes in Operating Assets and Liabilities. The section of the cash flow statement is where the changes in working capital live and breathe.

Breaking the sections down by generalities:

Operating part of the asset side of working capital will include:

Accounts receivable
Inventories
Prepaid expenses
And some uncommon current assets found in the financials

The big point of the working capital section is increasing any of these requires cash, a very important point, which we will come back to many times.

Current liabilities are the next section, including debt, which is not an operating factor of the business.

Remember that debt is a choice each business will make for financial reasons.

Items that are categorized as operations on the liabilities side of the ledger:

Accounts payable
Accrued expenses
Deferred revenue
Income taxes payable
And some uncommon liabilities found in the financials

Increasing any of these liabilities decreases the use of cash, which all companies like.

We referenced the business cycle earlier; stretching accounts payable and collecting our receivables earlier helps increase our cash available for operations.

Breaking down the “Change” in Working Capital

This section can be a little difficult to understand, so please read through it carefully and return to it as often as needed.

Most people assume the change in working capital means you calculate the change from one year to the next via these items from the balance sheet.

The wrong way to calculate, use the working capital in year one from the balance sheet, calculate the working capital in year two, and then subtract to get the change.

Change in working capital is a cash flow item that reflects the actual cash used to operate the business.

To explain this further, I will quote Jae Jun, who has written several great articles on this very subject.

“The “change” refers to how the cash flow has changed based on the working capital changes. You have to think and link what happens to cash flow when an asset or liability increases.

If current assets are increasing, cash is being used.

If current liabilities are increasing, less cash is being used as the company is stretching out payments or getting money upfront before the service is provided.

To tie this together, the “change” is about determining whether current operating assets or current operating liabilities are increasing.

If the final value for Change in Working Capital is negative, that means that the change in the current operating assets has increased higher than the current operating liabilities. Cash has been used, and this reduces Free Cash Flow.

If Changes in Working Capital is positive, the change in current operating liabilities has increased more than the part of the current assets. This means the use of cash has been delayed, which increases Free Cash Flow.

Put another way, if changes in working capital are negative, the company needs more capital to grow, and therefore working capital (not the “change”) is increasing.

If the change in working capital is positive, the company can grow with less capital because it is delaying payments or getting the money upfront. Therefore working capital is decreasing.”

He says that far more eloquently than I could have, and the last two sentences are key to understanding this concept.

Please re-read that part again until you understand the concept of changes in working capital; until you do the math, the above part will not make much sense.

How to Calculate Changes in Working Capital

Calculating the changes in working capital is fairly easy once you understand the principles behind the theory.

A word of caution, not all financial filings will list every line item the same, i.e., not all will list every asset or liabilities. Their terminology may vary from company to company or industry to industry.

If you remain unsure of any line item, my suggestion, use either our friend Mr. Google or email me, and I will give you a hand unless you have your handy-dandy accounting 101 books lying around.

To calculate our change in working capital, we will take all the items from the assets and add them together; then, we will do the same for the liabilities.

Once we have both the assets and liabilities tallied, we can subtract the liabilities from the assets to arrive at our number for the change in working capital.

The math portion of this calculation remains very simple; the harder part is understanding where the numbers come from and why it is important to focus on the change in working capital and interpret the result.

To make the changes in working capital a bit easier to calculate, I am including a excel calculator for you use, it is adaptable for you to add or subtract any line items you wish, but the calculator will make understanding the changes in working capital easier.

Next, let’s look at some examples from real companies to find our changes in working capital.

Real-Life Examples of Changes in Working Capital

For our first example, I would like to return to my old friend, Amazon; we can revisit their cash flow statement and look at our math.

To review the items from Oshkosh Corp that are assets are:

Receivables
Inventories
Other Current assets

From the current liabilities:

Accounts payable
Customer Advances
Payroll-related obligations
Income taxes
Other long-term liabilities and assets

Taking the numbers from the cash flow statement and adding them up, we get:

Oshkosh Corp Changes in Working Capital
Assets:
Receivables +	($18,163) million

Inventories +	$(9,487) million
Other current assets +	$0 million
Total current assets =	$(27,650) million

Next, looking at the liabilities from the cash flow statement, we get:

Liabilities
Accounts Payable +	3,602 million

Accrued Expenses +	$2,123 million
Unearned Revenue +	$2,314 million
Other current liabilities +	$0 million
Total current liabilities =	$8,039 million

Now adding the current assets to the current liabilities, we get:

Changes in working capital = $(27,650) million + $8,039 million = $(19,611) million

That was pretty easy, just some easy math for a change, and all the numbers laid out all nice and easy for us.

What does this negative number mean? It means that the changes in working capital are negative and that Amazon needs more capital to bridge the gap, and therefore, working capital is decreasing.

Some companies will do the math for us, adding a line item below the changes in working capital.

Not all companies will do this for you; most won’t.

Let’s look at a few more to help nail down this idea.

Next, let’s look at Hormel as we have used them for our owner earnings examples.

First, I will pull the cash flow statement, and then we can go from there.

Now, I will build our chart based on the numbers from above.

Line Item	Dollar Amount
Assets:
Receivables +	-$191,627 thousand
Inventories +	-$145,176 thousand
Prepaid Expenses +	$34,555 thousand
Pension and Post-retirement +	-$15,448 thousand
Total current assets =	-$317,696 thousand

Next, current liabilities:

Liabilities:
Accounts payable +	$115,099 thousand
Net income taxes payable +	$36,811 thousand
Total current liabilities =	$151,910

Now, we will calculate Hormel’s changes in working capital:

Changes in working capital = ($317,696) + $151,910 = ($165,786) thousand

Notice the different language for the assets and liabilities; it can get confusing; why spend a few minutes double-checking our terminology.

Also, notice that we have excluded the net cash at the bottom of the cash flow statement. The reason for this, we do not use cash in working capital.

The negative changes in working capital tell us Hormel uses its current cash flow to grow the assets, either buying more inventory or extending its receivables to receive better pricing on its inventories.

Bottom line, a negative change in working capital tells investors the company hopes to generate growth by spending cash on inventories or receivables.

Next up, let’s look at Verizon; we have used companies with a strong manufacturing base, whereas Verizon would be far more tech-based.

Ok, now that we have our cash flow statement for Verizon, we can go ahead and put together our chart.

Accounts receivable +	$1,592 million
Inventories +	-$905 millin
Prepaid expenses +	$150 million
Total current assets =	$837 million

And now current liabilities:

Accounts payable +	$1,457 million
Other, net +	-$93 million
Total current liabilities	$1,364 million

Verizon Changes in working capital = $837 + $1,364 = $2,201 million

Again notice the similarities in the language that each company uses when differentiating between assets and liabilities.

As before with Hormel, we are excluding the net cash. We are also not including the employee benefits and net as they can’t be included in our liabilities because they don’t contribute to our working capital.

We can see from our chart that Verizon has a negative number in their change in working capital.

Today I want to focus on how the changes in working capital work and that we understand the concept.

Final Thoughts

We have covered a lot of ground today; we have discussed the particulars of changes in working capital and what they mean for our business.

To drive the point home, I will include the quote from Jae Jun because I think it bears repeating and remains critical to understand what impact this has on our business.

“The “change” refers to how the cash flow has changed based on the working capital changes. You have to think and link what happens to cash flow when an asset or liability increases.

If current assets are increasing, cash is being used.

If current liabilities are increasing, less cash is being used as the company is stretching out payments or getting money upfront before the service is provided.

To tie this together, the “change” is about determining whether current operating assets or current operating liabilities are increasing.

Put another way, if changes in working capital are negative, the company needs more capital to grow, and therefore working capital (not the “change”) is increasing.

If the change in working capital is positive, the company can grow with less capital because it is delaying payments or getting the money upfront. Therefore working capital is decreasing.”

The key is to remember how the positive number and negative number correspond to our company and what it means to the growth of our company.

I have tried to include many different examples from a range of different industries so you can get an idea of how this will work for you.

As with everything I try to teach, please let me know if you have any questions or if there is anything I can make clearer for you.

Thanks for reading, and I hope you found some value in this post.

Take care,
