How to Read a Cash Flow Statement

A cash flow statement is one of the three core financial statements. It tracks the actual cash moving in and out of a business over a period of time, organized into three sections: operating activities, investing activities, and financing activities. Unlike the income statement, it ignores accruals and shows real cash — answering the question 'where did the money actually go?'

1. Operating activities: Cash from day-to-day business — customer payments minus payments to suppliers, employees, and for operating expenses. 2. Investing activities: Cash spent on or received from long-term assets — buying equipment, property, or selling assets. 3. Financing activities: Cash from owners and lenders — taking loans, repaying debt, owner contributions, and distributions. Adding all three to your starting cash gives your ending cash balance.

Profit (net income) is calculated on an accrual basis — revenue is recorded when earned and expenses when incurred, regardless of when cash changes hands. Cash flow tracks only actual money moving. A business can be profitable on paper but cash-poor if customers pay late (high accounts receivable), if it bought inventory in bulk, or if it made a large equipment purchase. This is why profitable businesses still go bankrupt — they run out of cash.

Operating cash flow (OCF) is the cash generated by a company's core business operations. It starts with net income and adjusts for non-cash items (like depreciation) and changes in working capital (accounts receivable, inventory, accounts payable). Positive OCF means the business generates more cash than it consumes from operations — the single most important sign of a healthy business.

The indirect method starts with net income and adjusts it back to cash: add back non-cash expenses (depreciation, amortization), subtract increases in current assets (AR, inventory), and add increases in current liabilities (AP). Most small businesses and accounting software use the indirect method because it ties directly to the income statement and balance sheet. The direct method instead lists actual cash receipts and payments.

Negative cash flow from investing usually means the business is buying long-term assets — equipment, vehicles, property, or other companies. This is often a healthy sign of growth and reinvestment. It only becomes a concern if the business is funding these purchases with debt it can't service, or if it's selling off assets (positive investing cash flow) just to stay afloat.

Free cash flow (FCF) = Operating Cash Flow − Capital Expenditures. It's the cash left after a business pays for the investments needed to maintain or grow operations. FCF is what's actually available to pay down debt, distribute to owners, or build reserves. Many investors consider free cash flow a better measure of financial health than net income because it's harder to manipulate.

The cash flow statement ties the income statement and balance sheet together. It starts with net income (from the income statement), adjusts for changes in balance sheet accounts (AR, inventory, AP, equipment), and ends with the change in cash — which must match the difference in the cash line between two balance sheets. All three statements must reconcile; if they don't, there's an error.
