Same profit, different cash left over
Two companies can each report $300 million of net income while one ends the year with $350 million of cash to spare and the other with $80 million. Profit is an accounting result; the actual capacity to pay dividends, repay debt, or reinvest comes from cash. Free cash flow (FCF) measures that capacity.
This guide covers the basic definition of free cash flow, the items companies handle differently, and how investment cycles and one-off changes affect the number, using a hypothetical comparison. It also lays out how to trace where the cash actually went.
Defining free cash flow
The most common definition is operating cash flow minus capital expenditure (purchases of property, equipment, and intangibles). It is the cash left after paying for the investment needed to maintain and grow the business. Both items appear in the cash flow statement prepared under IAS 7 or U.S. GAAP.
Free cash flow is not a defined accounting measure, so companies calculate it in slightly different ways. Check what a company includes and excludes in its reported FCF, and compare it with your own calculation from the statements.
A hypothetical comparison
The table compares two hypothetical companies with identical net income and operating cash flow.
| Item | Company A | Company B |
|---|---|---|
| Net income | 300 | 300 |
| Operating cash flow | 500 | 500 |
| Capital expenditure | 150 | 420 |
| Free cash flow | 350 | 80 |
| FCF as % of net income | 117% | 27% |
| (Memo) stock-based compensation added back in operating cash flow | 60 | 10 |
Company B needs far more investment each year to earn the same profit. Company A's FCF is large, but treating its $60 million of stock compensation as a real cost brings it to $290 million.
Items to align
Stock-based compensation is a non-cash expense, so it is added back to net income in operating cash flow. Companies that pay heavily in stock can therefore show large FCF while diluting existing shareholders. Recalculating FCF after subtracting stock compensation, as for Company A, is the more conservative view.
Leases matter too. Under IFRS, the principal portion of lease payments is classified in financing cash flow and so drops out of operating cash flow. For a company that leases most of its stores or equipment, subtracting lease principal payments gives a figure closer to the cash really left over. Companies also differ in where they classify interest paid and received.
The investment cycle
In a year of major expansion, free cash flow can fall sharply or turn negative. That alone does not make the company a poor one; what matters is how much the investment raises operating cash flow in later years.
Looking at three-to-five-year totals or averages is more stable than a single year. As a hypothetical example, FCF of -$100 million, $50 million, and $400 million over three years averages about $117 million, which can lead to a very different conclusion than any one of those years.
Separating one-off swings
Temporary working-capital moves also distort FCF. Delaying supplier payments past year-end flatters that year's operating cash flow and penalizes the next. A year with an unusually large inflow of customer prepayments has the same effect.
Proceeds from asset sales sit in investing cash flow and are not part of the usual FCF calculation, but some companies blend them into the figure they report. Check the line items of the cash flow statement for non-recurring inflows.
Tracing where the cash went
Once you have free cash flow, follow where it went. Investor.gov's guide to the 10-K points to the financial statements and the MD&A's liquidity discussion. A practical order:
- Copy operating cash flow and purchases of property, equipment, and intangibles for three to five years and calculate FCF.
- Check stock-based compensation and lease principal payments and calculate a conservative FCF.
- Look for working-capital swings or one-off inflows that distort particular years.
- From financing cash flow, record dividends, buybacks, borrowing, and repayments to see how FCF was used.
- If shareholder payouts consistently exceed FCF, find out what fills the gap: borrowing or falling cash balances.
Limits of free cash flow
Free cash flow is often seen as harder to manipulate than earnings, but the timing of investment and working-capital management can still move it a lot in the short run. It can also understate the future value of companies investing heavily for growth.
The companies in the table are hypothetical. For real analysis, use the latest filings with their dates and compare a company's reported FCF with your own calculation on a consistent definition.
