What Is Free Cash Flow?
Free cash flow is a way to look at how much cash a company generates after the spending needed to maintain and grow the business. Investors often compare it with earnings because accounting profit and cash generation can differ.
A common free-cash-flow formula
A common starting formula is:
- Free cash flow = operating cash flow − capital expenditures
Operating cash flow comes from the cash-flow statement. Capital expenditures are cash spent on property, equipment, technology infrastructure, stores, factories, or other long-lived assets.
Different analysts may adjust the formula, but the core question is the same: after running the business and investing in necessary assets, how much cash is left?
Why free cash flow matters
Free cash flow can support several uses:
- Paying down debt.
- Funding new products or expansion.
- Paying dividends.
- Buying back shares.
- Building cash reserves.
A company with rising earnings but consistently weak cash flow may deserve a closer look. The gap could come from working-capital timing, heavy growth investment, accounting items, or business stress.
What to check before relying on it
Free cash flow can be lumpy. A manufacturer, utility, or telecom company may have large capital spending needs. A software company may have lighter physical investment but other costs to watch.
Compare free cash flow over several periods, not just one quarter. Read the cash-flow statement and management discussion to understand why cash rose or fell.
