How to Read a Cash Flow Statement
There really are cases where a company goes under even though it showed a profit on the books. The reason is that it had no 'cash.' The cash flow statement shows exactly that flow of real money.
Why Look at Cash Separately from Profit
The profit on an income statement is calculated on an 'accrual basis.' Even if goods are sold on credit, it's recorded as revenue and profit. But until that credit is actually collected, there's no money in the company's account.
So even if there's a profit on the books, if cash is short, the company can collapse from being unable to pay salaries, interest, or supplier bills. This is called 'insolvency despite being profitable' (bankruptcy in the black).
The cash flow statement is a table that separately tracks only the 'cash' that actually moved, in order to catch this trap. It plays the role of a lie detector that verifies the quality of profit.
The Three Branches of Cash Flow
The cash flow statement splits the source and use of cash into three branches.
- Operating cash flow: the cash actually earned from the core business (selling goods and services). Having this consistently positive (+) is the baseline of a healthy company. - Investing cash flow: cash spent on buying equipment and buildings, acquiring other companies, and so on. Growing companies often have this negative (−) (they're investing in the future). - Financing cash flow: cash from taking on or repaying debt, issuing stock, or returning it to shareholders via dividends and buybacks.
The ideal picture is 'operating +, investing −, financing depending on the situation.' It means the company is investing in the future with the money it earned from operations.
Operating cash flow is usually derived by starting from net income, adding back expenses that didn't actually involve cash outflow (like depreciation), and adjusting for changes in receivables and inventory (the indirect method). So looking at the gap between net income and operating cash flow reveals the quality of profit.
Key Checkpoints for Beginners
Even though it looks complex, a beginner can grasp the big picture with just this much.
① Is operating cash flow consistently positive? (Does the core business really earn cash?) ② Is net income positive but operating cash flow persistently negative? (If so, you should question the quality of profit.) ③ Are dividends and investments funded by the core business's cash, or repeatedly patched up with debt and stock issuance?
Operating cash flow minus capital expenditure (capex) is exactly 'free cash flow (FCF).' Since it's money the company can truly use freely, it's covered more in a separate article.
Frequently Asked Questions
Q. Is negative investing cash flow bad?
No. On the contrary, growing companies commonly have negative investing cash flow because they spend money on factories, equipment, and research. The question is whether they invest 'with cash earned from the core business (operating activities)' or keep taking on debt to invest. You have to view the flows as a set.
Q. Can I know everything about a company just by looking at the cash flow statement?
Not quite. The cash flow statement is powerful because it's the 'cash perspective,' but you have to look together at profitability (income statement) and financial structure (balance sheet) for a complete picture. The three tables are originally connected as one, so reading them as a set is the standard.
