What are the three sections of the cash flow statement?

Cash from operations (the core business), cash from investing (buying and selling long-term assets), and cash from financing (money exchanged with lenders and shareholders). Add them up and you get the net change in the company's cash.

Why does the cash flow statement start with net income?

Because the operating section reconciles accounting profit back to actual cash. It starts from net income, then adds back non-cash charges like depreciation and adjusts for changes in working capital — turning a profit figure into a real cash figure.

What is the difference between profit and cash flow?

Profit is an accounting figure that includes non-cash items and records revenue when it's earned, not when cash arrives. Cash flow is the actual money moving in and out. A company can be profitable on paper and still run out of cash — which is exactly why this statement exists.

What is free cash flow?

Free cash flow is roughly operating cash flow minus capital expenditure — the cash left over after a company has maintained and grown its asset base. Many professionals consider it the truest measure of financial health, since it's money genuinely available to reward investors or reinvest.

The Cash Flow Statement Explained

The cash flow statement follows the real money — the actual cash moving in and out of a company — and reconciles reported profit to the change in the bank balance. It’s the antidote to the fact that profit and cash are not the same thing.

The income statement tells you whether a company is profitable. The cash flow statement tells you whether it actually has money — and those two questions have surprisingly different answers more often than you’d think.

Why it exists

Because net income includes non-cash items and accruals, a perfectly profitable company can still run out of cash — the classic way promising businesses die. The cash flow statement cuts through the accounting and shows the actual cash generated and used over a period, split into three activities. Follow it and you can’t be fooled by profit that never turned into money.

Cash from operations

Operating cash flow is the cash thrown off by the core business — the most important of the three. It typically starts from net income, then adds back non-cash expenses like depreciation and adjusts for changes in working capital (money tied up in unpaid invoices, inventory, and bills owed). A healthy company generates steady, positive operating cash flow. If profits are rising but operating cash flow isn’t, that’s a red flag worth investigating.

Cash from investing

Investing activities cover buying and selling long-term assets: capital expenditure ("capex") on equipment and property, acquisitions, and buying or selling investments. Heavy capex makes this section negative — which often isn’t bad at all. It’s frequently the sign of a company investing to grow.

Cash from financing

Financing activities cover the cash exchanged with investors and lenders: issuing or repaying debt, issuing or buying back shares, and paying dividends. Raising money is an inflow; repaying debt, buying back shares, and paying dividends are outflows.

Putting it together

Add the three up — operating, investing, and financing — and you get the net change in cash for the period, which ties directly to the cash line on the balance sheet. One especially useful figure falls out of this: free cash flow, roughly operating cash flow minus capex. It’s the cash left over after a company has maintained and grown its asset base — money genuinely available to reward investors or reinvest. Many professionals consider it the truest measure of a company’s financial health.

The cash flow statement tracks real cash, not accounting profit.
A profitable company can still run out of cash — this statement reveals it.
