How to calculate cash flow
The company's cash flow from operating activities, otherwise known as its operating cash flow, is the most commonly used metric to describe the "cash flow" of a business. And this certainly makes sense -- after all, investing activities such as buying Treasuries and financing activities such as repurchasing stock don't necessarily have to do with the financial health of the business itself. As a good rule of thumb, operating cash flow should be higher than the company's net income.
There are two methods of calculating the cash flow of a business -- the direct and indirect methods. Direct cash flow involves simply adding all of a business's cash transactions in the operating activities section of the cash flow statement. The indirect cash flow method starts with the business's net income and makes a series of adjustments.
It's important to realize that the method you use will produce the same end result for operating cash flow. It's also worth noting that cash flow statements generally provide a total of operating cash flow, as you'll see in the next section.
The other commonly used cash flow metric is known as free cash flow, which is defined as the company's net cash from operating activities (operating cash flow) minus its capital expenditures, which is listed in the investing activities section.
Free cash flow is an important metric because it shows the company's available cash generated during the time period, which can then be used to reinvest in the business, pay dividends, make acquisitions, repurchase stock, and for other desirable uses. Some businesses (airlines and oil companies, for example) can be rather capital-intensive, while others don't require a ton of ongoing capital investment. So, free cash flow can provide valuable insight into how much of a company's operating cash flow is actually available for use.
Example of a cash flow statement
To give you a better idea of what a cash flow statement looks like and how to use it in your investment analysis, here's a real-world example. This is Apple's (AAPL +0.54%) cash flow statement from the first quarter of its 2025 fiscal year.
