Free cash flow is the cash a company's operations bring in minus what it spends on equipment, buildings and other long-lived assets. What remains is the money available to repay debt, pay dividends, buy back shares or reinvest in the business. It comes straight from the cash flow statement, one of the three main financial statements a company reports alongside the income statement and balance sheet.
How it works
Where the figures come from
Free cash flow is built from the cash flow statement, the financial report that tracks cash moving in and out of a company over a period, as opposed to the income statement, which records revenue and expenses whether or not cash has changed hands. The two figures needed both sit on this one statement.
- Operating cash flow: the cash generated by a company's core business activities
- Capital spending, also called capital expenditures: cash spent on equipment, buildings, machinery and other long-lived assets
Operating cash flow then capital spending then the subtraction
The calculation has two steps. First find operating cash flow, then subtract capital spending; what remains is free cash flow.
As an illustration using round numbers, a company whose operations generated $800 million of cash and that spent $300 million on capital spending had free cash flow of $500 million ($800 million minus $300 million).
Why free cash flow can differ a lot from net income
Net income, the profit left after all expenses on the income statement, includes non-cash charges such as depreciation, the gradual expensing of an asset's cost over its useful life, which reduce reported profit without reducing cash. Net income also excludes the full upfront cash cost of buying equipment, which capital spending captures in the year the cash goes out.
Because of this timing gap, a company can report solid net income while spending heavily on capital projects, leaving far less free cash flow than its profit would suggest, or the reverse.
Free cash flow yield free cash flow divided by market cap
Free cash flow yield divides free cash flow by market capitalization, the total value of a company's outstanding shares, turning a dollar figure into a percentage that can be compared across companies of different sizes. In the illustration above, $500 million of free cash flow against a $10 billion market cap works out to a free cash flow yield of 5% ($500 million divided by $10 billion).
Why negative free cash flow is not always bad
Free cash flow can be negative even for a healthy, growing company.
- A retailer opening many new warehouses may spend more on capital projects than its operations currently generate in cash
- A company building data centers or factories for future growth may show negative free cash flow while that spending is underway
In both cases, the shortfall reflects a choice to invest now rather than a sign that operations are failing.
What it cannot tell you
Free cash flow does not say why a company is spending what it spends, whether that spending will pay off, or how its cash flow will look next year. It also does not adjust for one-time items, debt levels or how a company's capital spending compares with rivals in different industries.
A worked example with real figures
Apple generated $146.72 billion of operating cash flow over the four quarters to June 27, 2026, and spent $10.04 billion on capital spending, leaving free cash flow of $136.68 billion. Against a market cap of $5.09 trillion, that works out to a free cash flow yield of 2.68%, reflecting a business that converts most of its operating cash into free cash flow because it spends relatively little on physical assets.
Amazon generated more operating cash flow than Apple, $168.30 billion over the four quarters to September 30, 2026, but its capital spending of $215.19 billion exceeded that, producing negative free cash flow of $46.89 billion and a free cash flow yield of -1.78% against its $2.63 trillion market cap. The New York Times reported that Amazon and other large technology companies have been sharply increasing capital spending on data centers, with industry-wide spending roughly tripling over two years as the gap widened between cash generated and cash invested.
Placed side by side, the two figures show how the same calculation, operating cash flow minus capital spending, can produce very different results depending on how much a company is currently investing in long-lived assets.
