What Is Free Cash Flow?
Free cash flow is the cash a company produces through its operations, less the cost of expenditures on assets. In other words, free cash flow (FCF) is the cash left over after a company pays for its operating expenses and capital expenditures, also known as CAPEX.
Free cash flow is an important measurement since it shows how efficient a company is at generating cash. Investors use free cash flow to measure whether a company might have enough cash, after funding operations and capital expenditures, to pay investors through dividends and share buybacks.
Calculating Free Cash Flow
To calculate FCF, from the cash flow statement, locate the item cash flow from operations (also referred to as "operating cash" or "net cash from operating activities"), and subtract the capital expenditure required for current operations.
The formula for free cash flow is:
FCF=Operating Cash Flow − Capital Expenditureswhere:
Example of Free Cash Flow
Cash Flow From Operating Activities=$1.944 billionCapital Expenditures=$760 million

Interpreting Free Cash Flow
Of Note: the $411 million credit from the sale of property and equipment listed under Cash Flows from Investing Activities was not included since it's a one-time event and not part of everyday cash flow activities.
Growing free cash flows are frequently a prelude to increased earnings. Companies that experience surging FCF—due to revenue growth, efficiency improvements, cost reductions, share buybacks, dividend distributions, or debt elimination—can reward investors tomorrow. That is why many in the investment community cherish FCF as a measure of value. When a firm's share price is low and free cash flow is on the rise, the odds are good that earnings and share value will soon be heading up.
By contrast, shrinking FCF might signal that companies are unable to sustain earnings growth. An insufficient FCF for earnings growth can force companies to boost debt levels or not have the liquidity to stay in business.
To calculate free cash flow another way, locate the income statement and balance sheet. Start with net income and add back charges for depreciation and amortization. Make an additional adjustment for changes in working capital, which is done by subtracting current liabilities from current assets. Then subtract capital expenditure (or spending on plants and equipment):
|- Change in Working Captial|
|- Capital Expenditure|
|= Free Cash Flow|
It might seem odd to add back depreciation/amortization since it accounts for capital spending. The reasoning behind the adjustment is that free cash flow is meant to measure money being spent right now, not transactions that happened in the past. This makes FCF a useful instrument for identifying growing companies with high up-front costs, which may eat into earnings now but have the potential to pay off later.
The Bottom Line
One drawback to using the free cash flow method is that capital expenditures can vary dramatically from year to year and between different industries. That's why it's critical to measure FCF over multiple periods and against the backdrop of a company's industry.
It's important to note that an exceedingly high FCF might be an indication that a company is not investing in its business properly, such as updating its plant and equipment. Conversely, negative FCF might not necessarily mean a company is in financial trouble, but rather, investing heavily in expanding its market share, which would likely lead to future growth.
