What is a Cash Flow Statement?

The cash flow statement tracks the actual movement of cash into and out of a business during a period of time. While the income statement shows accounting profit, the cash flow statement shows reality: did we actually receive money, and did we actually spend it?

The Three Sections of a Cash Flow Statement

Operating activities show cash generated by the core business — collecting from customers, paying suppliers and employees. This is the most important section; strong, positive operating cash flow means the business is self-sustaining. Investing activities show cash spent on or received from long-term assets — buying equipment, selling a building. Financing activities show cash from or to investors and lenders — taking a loan, repaying debt, paying dividends.

Why Cash Flow Differs From Profit

A company can show a profit on its income statement but still be cash-negative. This happens because of timing differences: revenue is recognized when earned (not when cash arrives), expenses are recorded when incurred (not when paid), and capital expenditures are depreciated over years rather than expensed immediately. The cash flow statement bridges this gap, converting accrual profit into actual cash reality.

The Most Important Number: Free Cash Flow

Free cash flow — operating cash flow minus capital expenditures — is what serious investors watch most closely. It shows how much cash the business generates after maintaining and growing its assets. Positive free cash flow means the business can fund growth, pay down debt, or return money to owners without relying on external financing.
