# How to Read a Cash Flow Statement

> A cash flow statement tracks actual cash in and out over a period, split into operating, investing, and financing activities. Unlike the income statement's accrual accounting, it shows real cash — the best place to judge whether profits are backed by money in the bank.

## Why cash flow differs from profit

The income statement uses accrual accounting — revenue when earned, not when paid. The cash flow statement shows actual cash, which is why a profitable company can still run out of money and why cash flow is harder to manipulate.

## The three sections

| Section | Captures | Watch for |
|---------|----------|-----------|
| Operating (CFO) | Cash from core operations | Positive, ideally > net income |
| Investing (CFI) | Capex, acquisitions, asset sales | Negative is normal |
| Financing (CFF) | Debt, dividends, buybacks | How the company funds itself |

## Operating cash flow

CFO starts from net income, adds back non-cash charges, adjusts for working capital. Red flag: profits rising while CFO stalls — deteriorating earnings quality.

## Free cash flow

CFO minus capex = free cash flow (/learn/fcf) — cash for dividends, buybacks, debt.

## Earnings quality

Compare CFO to net income over years. CFO ≥ net income = high quality. Net income >> CFO warrants a closer look.

## FAQ

**Why is the cash flow statement important?** It shows the real cash a company generates, which is harder to manipulate than accrual-based earnings. It reveals whether reported profits are backed by actual cash and whether the business can fund itself.

**What is the difference between cash flow and profit?** Profit (net income) is an accrual measure that records revenue and expenses when earned or incurred. Cash flow tracks actual money moving in and out. A company can be profitable on paper yet cash-poor if customers haven't paid.

**What is a good operating cash flow?** A healthy company generates operating cash flow that is positive, growing, and at least in line with (ideally above) its net income. That indicates its profits are backed by real cash.
