The Restaurant That Made Money But Went Bankrupt
Chef Zhang's restaurant had ¥5 million in revenue last year. After all costs, net profit was ¥1 million. Looks great, right?
But here's the problem: ¥800K of that revenue is corporate IOUs that haven't been collected. He spent ¥600K renovating the kitchen. And he has ¥300K in loan payments due. His bank account is empty. The restaurant is profitable on paper but broke in reality.
Net Profit vs Free Cash Flow
Net Profit is an accounting concept — it includes revenue that hasn't been collected, depreciates equipment over time, and uses many assumptions. It can be manipulated.
Free Cash Flow (FCF) = Operating Cash Flow − Capital Expenditures. It's the actual cash left after running the business and reinvesting. You can't fake cash.
"A good company is one that makes money lying down — pure cash inflow. If a company reports high profits but has no cash, something is wrong."
| Metric | Net Profit | Free Cash Flow |
|---|---|---|
| What it measures | Accounting earnings | Actual cash generated |
| Can be manipulated? | Yes (accounting tricks) | Very hard to fake |
| Includes uncollected revenue? | Yes | No |
| Includes depreciation? | Yes (reduces profit) | No (adds it back) |
| Most useful for | Regulatory reporting | Actual business health |
Why FCF Matters More for Investors
💡 FCF Is King
- Dividends come from cash, not accounting profits
- Share buybacks require actual cash
- Debt repayment needs real money, not paper earnings
- A company with high profits but negative FCF is burning cash
- Warren Buffett: 'Owner earnings (≈FCF) is the real measure of a business'
Next time you look at a company, don't just check the bottom line. Ask: how much actual cash did this business generate?
💡 Key Summary
- Net profit is an accounting concept; FCF is real cash
- Profitable companies can go bankrupt if they run out of cash
- FCF = Operating Cash Flow − Capital Expenditures
- Look for companies where FCF ≥ Net Profit consistently
- Duan: 'Good companies make money lying down — pure cash inflow'
- When in doubt, follow the cash, not the earnings
一个赚钱却破产的餐厅
老李开了一家火锅店。去年营业额500万，净利润80万——看起来不错对吧？但到了年底，他发现银行账户只剩3万块。
为什么？因为他年初花了200万装修新店（资本支出），又花了150万囤了大量底料和食材（存货增加），还有50万的应收账款没收回来（企业客户赊账）。利润表上赚了80万，但真正的现金流是负数。
这就是为什么段永平说「好公司要看自由现金流，不能只看利润」。利润是会计师算出来的，但现金流是银行账户里的实数。
自由现金流（FCF）是什么
自由现金流 = 经营活动产生的现金流 - 资本性支出
翻译成人话：公司做主业赚了多少真金白银（经营活动现金流），减去维持和扩张业务必须花的钱（买设备、建厂房等资本支出），剩下的就是「自由」的——可以拿来分红、回购股票、偿还债务，或者存着以备不时之需。
"好公司就是「躺着赚钱」的公司。纯粹的现金流入，不需要不断追加投入来维持利润。"
为什么利润可以「造假」但现金流很难
| 会计操作 | 对利润的影响 | 对现金流的影响 |
|---|---|---|
| 提前确认收入 | 利润↑ | 现金没变 |
| 延长折旧年限 | 利润↑ | 现金没变 |
| 将费用资本化 | 利润↑ | 现金没变 |
| 减少坏账准备 | 利润↑ | 现金没变 |
| 应收账款增加 | 利润不变 | 现金↓ |
每一种常见的会计操纵，都只影响利润表，不影响现金流量表。这就是为什么老道的投资者（包括段永平、巴菲特）都把自由现金流当做最核心的指标——它最难被操纵。
实战案例：茅台 vs 京东方
| 指标 | 贵州茅台 | 京东方 |
|---|---|---|
| 净利润（2024） | 862亿 | 36亿 |
| 经营现金流 | 750亿 | 300亿 |
| 资本支出 | 85亿 | 280亿 |
| 自由现金流 | 665亿 | 20亿 |
| FCF/净利润 | 77% | 56% |
| 商业模式 | 酿酒卖酒，几乎不用新设备 | 面板制造，需要不断建新产线 |
| 段永平的评价 | 「印钞机」 | — |
茅台每赚100块利润，有77块变成了真金白银的自由现金流。京东方每赚100块利润，只有56块变成自由现金流——大部分都要投回去买新设备。这就是「轻资产」和「重资产」公司的根本区别。
💡 自由现金流核心要点
- FCF = 经营现金流 - 资本支出 → 真正「自由」可支配的钱
- FCF/净利润 比值越高越好（>70%为优秀）
- 连续多年FCF为负 → 公司可能在烧钱模式，需要警惕
- FCF充裕的公司有能力分红、回购、抵御危机
- 重资产行业（制造、基建）FCF天然偏低，不能和轻资产行业直接比
