The cash flow statement: why profit isn't cash
Profit and cash are not the same thing. This lesson shows the three ways cash moves through a company, how to work out free cash flow, and how a business that reports a profit can still run out of money.
Why profit and cash drift apart
The income statement follows accounting rules about when to count a sale or a cost. Those rules don’t wait for money to change hands. Three gaps show up again and again:
- Sales are counted on delivery, not payment. When Pebble Creek Bikes ships 20 bikes to a shop that pays in 60 days, the sale counts today. The cash arrives later, or not at all.
- Unsold goods aren’t a cost yet. Parts and labor for bikes sitting in the warehouse are paid for now, but they hit the income statement only when the bikes sell.
- Big purchases are spread out. A $150,000 machine drains the bank account today. On the income statement it shows up a slice at a time, as depreciation, over many years.
The cash flow statement ignores those timing rules. It tracks the actual dollars that came in and went out during the period, and it explains exactly why the bank balance changed.
Three kinds of cash flow
- Operating cash flow comes from the everyday business: collecting from customers, and paying suppliers, workers, interest and taxes.
- Investing cash flow is money spent on, or received from, long-term assets such as machines, buildings or another company. Spending on equipment and buildings is called capital expenditures, or capex.
- Financing cash flow is money moving between the company and the people who fund it: borrowing, repaying loans, selling new shares, paying dividends.
Add the three together and you get the change in cash for the period.
Starting from net income
Most companies build the operating section backward. They start with net income from the income statement, then undo the parts that weren’t cash:
- Add back depreciation. It lowered profit, but no money left the bank.
- Subtract a rise in receivables. Those sales were counted, but customers haven’t paid yet.
- Subtract a rise in inventory. Cash went into goods that haven’t sold.
- Add a rise in accounts payable. Those costs were counted, but the company hasn’t paid its suppliers yet.
Here is Pebble Creek’s year. Net income comes from the income statement lesson. Every change comes from the start and end columns in the balance sheet lesson.
| Line | Amount |
|---|---|
| Operating activities | |
| Net income | $120,000 |
| Add back depreciation | +$100,000 |
| Receivables rose ($150,000 to $250,000) | −$100,000 |
| Inventory rose ($250,000 to $400,000) | −$150,000 |
| Accounts payable rose ($250,000 to $300,000) | +$50,000 |
| Cash from operations | $20,000 |
| Investing activities | |
| New equipment (capex) | −$150,000 |
| Financing activities | |
| New bank loan | +$200,000 |
| Loan repaid | −$100,000 |
| Dividends paid | −$20,000 |
| Cash from financing | +$80,000 |
| Change in cash | −$50,000 |
Operating: $120,000 + $100,000 − $100,000 − $150,000 + $50,000 = $20,000.
All three together: $20,000 − $150,000 + $80,000 = −$50,000. Cash started the year at $200,000 and ends at $150,000, exactly what the balance sheet shows.
The other lines tie out too. Equipment: $1,050,000 + $150,000 bought − $100,000 depreciation = $1,100,000. Bank debt: $600,000 + $200,000 borrowed − $100,000 repaid = $700,000.
Free cash flow
Free cash flow is cash from operations minus capital expenditures. It is the cash the business produced after paying to keep and grow its equipment. That money is free to pay dividends, pay down debt or save.
Pebble Creek: $20,000 − $150,000 = −$130,000. The everyday business didn’t produce enough cash to pay for its own new machines, so the bank loan filled the hole and paid the dividend too. One negative year while a company grows isn’t alarming by itself. Year after year of it, covered by borrowing, is.
How a profitable company runs out of cash
Pebble Creek earned $120,000, yet it ended the year with less cash and more debt. Where did the money go?
- Customers paid late. To win new bike shops, Pebble Creek let them pay later. Receivables jumped $100,000. That is profit sitting in other people’s bank accounts.
- Inventory piled up. It built bikes for shops that didn’t reorder as fast as hoped. That tied up $150,000 of cash in the warehouse.
- Slower bill-paying helped only a little. Paying its own suppliers later freed $50,000.
Now picture next year going the same way. Pebble Creek starts with $150,000. Operations bring in $20,000. It buys another $150,000 of equipment, must repay the $100,000 of loan due within the year, and pays a $20,000 dividend:
$150,000 + $20,000 − $150,000 − $100,000 − $20,000 = −$100,000.
A bank account can’t go below zero. So Pebble Creek has to borrow again, skip the dividend, delay the machines or collect from customers faster. If the bank says no, a company that reports a profit every year is out of cash. That is how many fast-growing businesses fail. When there is substantial doubt that a company can keep going for another year, its auditor has to flag it; see the going-concern lesson.
Warning signs to look for
- Cash from operations stays far below net income, year after year. Pebble Creek turned $120,000 of profit into just $20,000 of operating cash.
- Receivables and inventory grow faster than sales.
- Dividends or share buybacks are paid with borrowed money.
Over several years, a healthy company’s operating cash flow usually runs about even with, or above, its net income. Cash is also harder to dress up than profit, which leans on estimates.
- Cash from operations
- Cash produced or used by the everyday business.
- Cash from investing
- Cash spent on or received from long-term assets.
- Capital expenditures (capex)
- Cash spent on equipment, buildings and other long-lasting assets.
- Cash from financing
- Cash from borrowing or selling shares, minus loan repayments, dividends and buybacks.
- Free cash flow
- Cash from operations minus capital expenditures.
- Accounts receivable
- Money customers owe for things already delivered.
Where to see it on Filing.fyi
The full cash flow statement is in each 10-K and 10-Q, linked from a company page’s filing timeline. Two of the nine Piotroski F-Score tests come straight from it: is operating cash flow positive, and is it larger than net income? Pebble Creek would pass the first and fail the second. The Beneish M-Score also measures the gap between profit and operating cash, and it checks whether receivables grew faster than sales. A big gap pushes that score toward the warning zone.
- Profit follows accounting timing rules; the cash flow statement follows actual dollars.
- Operating, investing and financing cash flows add up to the change in cash.
- Free cash flow is operating cash minus capital expenditures.
- Slow-paying customers and piled-up inventory can drain a profitable company.
- Operating cash far below net income, year after year, deserves a closer look.
