The cash flow statement, section by section
6 min read · updated July 2, 2026
Here's the whole reason this statement exists: a company can report a profit and still bleed cash, and the cash flow statement is where that gap shows up. The income statement is built on accruals, meaning you book a sale when you earn it, not when the money lands. So net income is an opinion about a period. Cash is a fact. This statement walks you from the opinion back to the fact.
If you can build it section by section and explain why each line moves cash, you understand the plumbing that a first-year analyst gets paid to model. Let's build it.
Where it starts: net income
The top line of the cash flow statement is net income, pulled straight from the bottom of the income statement. That's the indirect method, and it's the only one you'll see in interviews and in almost every real filing. You start with the accrual profit number and then make a series of adjustments to strip the accruals back out and get to cash.
Three sections do that work: operating, investing, financing.
Section 1: Cash from operations (CFO)
This is the cash the core business actually generated. Two kinds of adjustments get you there.
Add back non-cash charges. Some expenses reduced net income but no cash left the building. The big one is depreciation and amortization (D&A). You spent the cash on the asset years ago; this period's depreciation is just an accounting allocation. So you add it back. Same logic for stock-based comp and asset impairments. They hit the income statement, but no check was written this period.
Adjust for changes in working capital. This is where beginners flip signs, so slow down. Working capital is the money tied up in running the business day to day, and when it moves, cash moves the opposite way for assets.
- An operating asset goes up = a use of cash. If accounts receivable rises, you booked the revenue but haven't collected. If inventory rises, you spent cash to build product still sitting on the shelf.
- An operating liability goes up = a source of cash. If accounts payable rises, you're holding onto your suppliers' cash longer. If deferred revenue rises, a customer prepaid for something you haven't delivered, so cash is in the door with no revenue recognized yet.
Think of it from the checking account, not the ledger. Selling on credit grows receivables and feels like profit, but no cash arrived, so it gets subtracted. Delaying a payment to a supplier grows payables and keeps cash in your account, so it gets added. Assets tie up cash; liabilities free it up.
Section 2: Cash from investing (CFI)
This section is about long-term assets: buying them and selling them. The line that matters almost every time is capital expenditures, or CapEx, the cash spent on property, plant, and equipment (PP&E). That's a cash outflow, so it's negative. Acquisitions of other companies land here too, as does cash received from selling a division or a building.
Here's the tell that separates a real business from a cheap-looking one. EBITDA ignores CapEx entirely. A capital-hungry business (factories, fleets, fiber) can post strong EBITDA and convert almost none of it to cash because it's plowing everything back into PP&E. CFI is where that reality lives. It's why EV/EBITDA can look cheap while cash flow tells a different story.
Section 3: Cash from financing (CFF)
This section tracks cash between the company and the people who fund it: lenders and shareholders.
- Debt: drawing on a loan or a revolver brings cash in; repaying principal sends it out.
- Equity: issuing shares raises cash; a share repurchase spends it.
- Dividends: cash paid out to shareholders, a straight outflow.
Note the split: paying down debt principal shows up here in financing, but the interest on that debt already ran through the income statement above net income. Don't double-count it.
Closing the loop: the net change in cash
Add the three sections and you get the net change in cash for the period. Add that to the cash you started with, and you have your ending cash balance, which drops directly onto the balance sheet as the new cash line. That's the loop closing. If you've done every adjustment correctly, the balance sheet still balances. For the full mechanics of how all three tie together, see Walk me through the three statements.
Two errors sink this answer, over and over. One: forgetting to add back non-cash charges. Depreciation, amortization, and stock comp reduced net income, but no cash moved, so they get added straight back in operations. Two: getting the sign of a working-capital change backwards. An increase in receivables or inventory uses cash (subtract it); an increase in payables or deferred revenue is a source of cash (add it). When you're not sure, ask "did money actually leave my account?" and let the answer set the sign.
Why profit is not cash: a quick example
Say you sell $100 of product entirely on credit. Net income shows the profit, but receivables jump $100 and not a dollar has been collected. On the cash flow statement, that $100 rise in receivables is subtracted, so CFO reflects $0 collected. The profit is real on paper. The cash is not there yet. Flip it: a subscription business that collects a year upfront books deferred revenue, so cash shows up long before the income statement recognizes it. That's why software companies can run on customer float, and it's exactly the kind of nuance that reads as depth in a Superday.
Rehearse the sequence out loud until it's automatic: net income, add back non-cash, adjust working capital (right signs), then investing, then financing, then net change lands on the balance sheet. When an interviewer changes one line and asks you to trace it, that fixed order is your safety rail. Analysts who can run it without pausing signal they've actually built models, not just memorized a script.
Glossary
New to the lingo? Every term used above, in plain English.
- Cash flow statement
- The report that tracks the actual cash moving in and out of a company, bridging accrual profit to real cash. It explains why a profitable company can still run low on cash.
- Net income
- A company profit after all expenses, interest, and taxes are taken out. It is the bottom line of the income statement, also called earnings.
- Accrual accounting
- Recording a sale when it is earned and a cost when it is incurred, not when the cash actually changes hands. It is why reported profit and cash can differ.
- Non-cash charge
- An expense that lowers reported profit but involves no cash leaving the company, such as depreciation or amortization. It gets added back on the cash flow statement.
- D&A (Depreciation and Amortization)
- Spreading the cost of long-lived assets over the years they are used. Depreciation is for physical assets, amortization for intangible ones. Both are non-cash expenses.
- Working capital
- The short-term money tied up in day-to-day operations, roughly current assets like receivables and inventory minus current liabilities like payables.
- Accounts receivable (AR)
- Money customers owe a company for sales already made but not yet paid for. It is an asset, and it ties up cash until the customer pays.
- Inventory
- The goods a company has made or bought but not yet sold. It is a current asset, and cash stays locked up in it until it is sold.
- Accounts payable (AP)
- Money a company owes its suppliers for goods or services it has received but not yet paid for. It is a liability, and it is a source of short-term financing.
- Deferred revenue
- Cash a company has collected for a product or service it has not delivered yet, like an annual subscription paid up front. It sits as a liability until it is earned.
- CapEx (Capital Expenditures)
- Cash a company spends to buy or upgrade long-lived assets like equipment, factories, or technology. It is an investment in the business, not a day-to-day expense.
- PP&E (Property, Plant and Equipment)
- The long-lived physical assets a company uses to operate, like buildings, machines, and equipment. Its value drops over time through depreciation.
- Dividend
- A cash payment a company makes to its shareholders out of profits. It is one of the two main ways (along with buybacks) a company returns cash to owners.
- Revolver (revolving credit facility)
- A flexible line of credit a company can draw on and repay as needed, like a corporate credit card. In a model it plugs any short-term cash shortfall.
- Balance sheet
- A snapshot at a single point in time of what a company owns (assets) and what it owes (liabilities), plus the equity left for owners. Assets always equal liabilities plus equity.
- EBITDA
- Earnings Before Interest, Taxes, Depreciation, and Amortization. A rough proxy for a company’s operating cash profit, before financing and accounting choices.
