Free Cash Flow — CFO minus Capex
Learning Objectives
After reading this chapter, you will be able to:
- Apply: FCF = OCF − Capex — cash available after running and maintaining the business. Most reliable measure of financial strength and shareholder return capacity. Negative FCF requires context (growth vs weakness). Always analyze multi-year trends. Buffett and value investors prioritize FCF over accounting profit
- Apply Free Cash Flow (FCF) metrics and formulas using consolidated NSE/BSE annual report data
- Identify red flags when interpreting Free Cash Flow (FCF): Profit rising but FCF not
- Connect Free Cash Flow (FCF) analysis to peer comparison and buy/hold/avoid decisions
Introduction
Revenue can be inflated; Profit can be shaped by accounting rules; EPS can be boosted by buybacks. But:
Cash does not lie.
Free Cash Flow answers: "After running and maintaining the business, how much Cash is actually left?"
Core Concepts
Financial Terms
| Term | Meaning |
|---|---|
| Free Cash Flow (FCF) | Operating Cash Flow − Capital Expenditure |
| Operating Cash Flow (OCF) | Actual cash from business operations |
| Capex | Capital Expenditure — Factory, Machines, Plant, Warehouse |
| FCF Margin | FCF ÷ Revenue × 100 |
| Capital Allocation | Dividend, Buyback, Debt Repayment, Acquisition, Expansion |
Investment Decision
| Check | Criteria |
|---|---|
| FCF | Positive and rising |
| FCF vs Profit | Convergence preferred |
| ROCE | Strong |
| Debt | Low relative to FCF |
| Trend | 5–10 year view |
Decision: Positive FCF + Rising Trend + Strong ROCE + Low Debt → worth further study.
Golden Rule: Cash Flow shows truth; FCF shows wealth creation potential.
"Revenue tells the story; Profit creates hope; Cash Flow shows truth; Free Cash Flow shows wealth creation potential."
| Item | Amount |
|---|---|
| Operating Cash Flow | ₹500 Cr |
| Capex | ₹200 Cr |
| FCF | ₹300 Cr |
Business actually saved ₹300 Cr — usable for Dividend, Buyback, Debt, Acquisition, Expansion.
| Item | Amount |
|---|---|
| Profit | ₹100 Cr |
| Capex + Maintenance | ₹90 Cr |
| Free Cash | ₹10 Cr |
Profit ₹100 Cr sounds great; actual free cash only ₹10 Cr — Analyst vs Retail Investor divergence point.
| Item | Amount |
|---|---|
| Revenue | ₹1000 Cr |
| FCF | ₹200 Cr |
| FCF Margin | 20% |
₹20 Free Cash on every ₹100 of Sales.
| Company A | Company B | |
|---|---|---|
| Profit | ₹100 Cr | ₹100 Cr |
| FCF | ₹90 Cr | ₹5 Cr |
| Verdict | Excellent | Investigation Required |
| Year | FCF |
|---|---|
| 2021 | ₹100 Cr |
| 2022 | ₹150 Cr |
| 2023 | ₹200 Cr |
| 2024 | ₹250 Cr |
| 2025 | ₹300 Cr |
Excellent rising trend — minimum 5–10 years analysis recommended.
Positive FCF: Cash generation, self-funded growth possible
Negative FCF: Not always bad — ask why?
- Expansion Capex → acceptable
- Weak business → problem

Visual Guide
Worked Example — Indian Market
FCF Calculation
CFO ₹200 Cr, Capex ₹80 Cr → FCF ₹120 Cr. If PAT ₹150 Cr but FCF ₹40 Cr → earnings quality concern.
Real World Example
Monthly Salary ₹1,00,000; Expenses ₹60,000 → ₹40,000 saved. But the bike breaks down and a new bike costs ₹20,000 — actual free cash:
In business too: Profit ≠ Free Cash after maintenance/expansion spending.
Case Study
| Company | FCF Focus |
|---|---|
| TCS | Strong, Stable FCF expected — Asset-Light IT business |
| BEL | OCF, Working Capital, FCF Trend |
| Maithan Alloys | FCF often more important than Profit in Commodity Cycle |
FCF + Debt:
| Company A | Company B | |
|---|---|---|
| Debt | ₹1000 Cr | ₹1000 Cr |
| FCF | ₹500 Cr | ₹20 Cr |
| Risk | Comfortable | Risky |
FCF + Dividend: Dividend comes from Cash, not Profit — FCF supports dividend sustainability.
Buffett Test: "If I buy the whole company, how much Free Cash will it generate every year?"
CFA Exam Tip
Always ask FCF before Profit alone. FCF funds all shareholder returns — Dividends, Buybacks, Debt repayment.
Strong FCF = Strong Capital Allocation Flexibility
Key question for negative FCF: Expansion investment or business weakness?
Common Mistakes
- Profit rising but FCF not
- FCF continuously negative (without clear growth capex plan)
- Debt rising + Weak FCF
- Revenue rising but Cash not
- Management raising equity while FCF weak
Key Takeaways
FCF = OCF − Capex — cash available after running and maintaining the business. Most reliable measure of financial strength and shareholder return capacity. Negative FCF requires context (growth vs weakness). Always analyze multi-year trends. Buffett and value investors prioritize FCF over accounting profit.
