What Is Free Cash Flow?
Free Cash Flow (FCF) is the amount of cash a company generates after paying for operating expenses and capital expenditures (CapEx). It represents the money that’s truly available for shareholders and reinvestment.
Free Cash Flow=Operating Cash Flow−Capital Expenditures\text{Free Cash Flow} = \text{Operating Cash Flow} – \text{Capital Expenditures}
Unlike accounting-based profits, FCF focuses on real money in the bank.

How to Calculate Free Cash Flow
You can find this data on a company’s cash flow statement—not the income statement. Look for:
- Operating Cash Flow (from business operations)
- Capital Expenditures (typically found under “Investing Activities”)
Here’s a basic example:
- Operating Cash Flow = $5 billion
- Capital Expenditures = $1.5 billion
- Free Cash Flow = $5B – $1.5B = $3.5 billion
You can quickly find Operating Cash Flow and Capital Expenditures on financial sites like Yahoo Finance, which offers user-friendly charts and historical financial data.

How Warren Buffett Uses Free Cash Flow
Warren Buffett popularized a concept called owner earnings, which closely mirrors FCF. In his view, the value of a business is the present value of its future cash flows.
“The value of any business is determined by the cash it’s going to produce from now until forever.” — Warren Buffett
Buffett uses tools like the Discounted Cash Flow (DCF) model to estimate intrinsic value:

Real-World Examples of Free Cash Flow Analysis
✅ Apple (AAPL)
- FCF (2023): $100+ billion
- Apple has consistently high FCF, allowing it to buy back shares and pay dividends comfortably.
⚠️ AT&T (T)
- FCF: Often strained by high debt and CapEx
- Dividend cuts in the past were predictable by declining FCF.
🚀 Tesla (TSLA)
- Historically burned cash, but now generating strong FCF due to operational improvements.
Use sites like Yahoo Finance or Morningstar to find FCF metrics easily.
Common Mistakes When Using Free Cash Flow
- Ignoring industry context: Capital-heavy industries may show low FCF but still be sound.
- Using one year of data: Always review 5–10 year trends.
- Not adjusting for unusual items: Look deeper into notes for one-time CapEx spikes.

FAQs About Free Cash Flow
1. What is a good Free Cash Flow yield?
A good Free Cash Flow yield is typically above 5%, meaning the company generates free cash flow equivalent to 5% or more of its market cap. This suggests the company is returning solid value for each dollar investors pay. However, what’s “good” can vary by industry—utilities and telecoms may have lower yields, while tech companies often post higher ones. Always compare FCF yield to peers and historical norms for context.
2. Can a company have high earnings but low Free Cash Flow?
Yes, and this is a major red flag. High earnings with low or negative free cash flow often indicate that profits are being tied up in accounts receivable, inventory, or are the result of aggressive accounting. In such cases, the company might look profitable on paper but isn’t generating actual cash. That’s why savvy investors rely on free cash flow—it shows how much money is really available to run and grow the business.
3. Why is Free Cash Flow more reliable than net income?
Net income can be influenced by non-cash items like depreciation, stock-based compensation, or tax strategies. It also follows accounting standards (GAAP), which can sometimes obscure reality. Free Cash Flow, on the other hand, shows actual cash generated after essential reinvestments. It cuts through the accounting noise and reveals whether a business is financially healthy. If a company reports strong FCF consistently, it usually means the profits are real and sustainable.
4. How does Free Cash Flow impact dividends?
Dividends are paid out of real cash, not accounting profits. Free Cash Flow is a key indicator of a company’s ability to sustain and grow dividends. If a company consistently generates more FCF than it pays out in dividends, that dividend is likely safe. But if dividend payouts exceed FCF over time, it’s a warning sign the company might borrow or deplete reserves to maintain the payout—often a setup for a future dividend cut.
5. Where can I find Free Cash Flow data?
You can find FCF data on a company’s cash flow statement, usually located in quarterly or annual reports (10-Q or 10-K). Alternatively, free financial websites like Yahoo Finance or Morningstar show “Operating Cash Flow” and “Capital Expenditures”—subtract the latter from the former to get FCF. For detailed analysis, look at the company’s investor relations site or use spreadsheet models like a Discounted Cash Flow (DCF) valuation.
Conclusion
Free Cash Flow is the unsung hero of fundamental analysis. It gives you a clear, no-nonsense view of how much actual cash a business is producing and what it can do with that cash. For long-term investors who want to own high-quality companies, FCF should be a key tool in your arsenal.
It doesn’t mean you ignore other metrics, but using free cash flow will help you avoid businesses that look good on paper but fail to produce real results. Combine it with other principles of value investing and compounding, and you’ll be ahead of 90% of market participants.
Free Cash Flow is more than a number—it’s a mindset.
Happy Investing!
