Finance & Accounting
Definition
A cash flow statement shows how cash moves in and out of a business over a specific period, divided into operating, investing, and financing activities. Unlike the income statement, it shows actual cash movement — not accrual-based accounting entries — making it the definitive measure of a business's liquidity.
Operating cash flow reflects cash from core business operations — net income adjusted for non-cash items (depreciation, amortization) and changes in working capital (receivables, payables, inventory). Investing cash flow covers capital expenditures and asset sales. Financing cash flow includes debt proceeds and repayments, equity raises, and dividends. Free Cash Flow (FCF) = Operating Cash Flow − Capital Expenditures — a critical metric for valuing businesses and assessing ability to service debt or self-fund growth. A company can be profitable (positive net income) but cash-flow negative if working capital grows faster than earnings — common for rapidly growing businesses. The cash flow statement reconciles the difference between reported net income and actual cash generated, explaining why profitable companies can run out of cash.
The cash flow statement is often the most important financial statement because cash is what keeps a business alive, not accounting profits. Investors and lenders scrutinize Free Cash Flow to assess health and valuation. A fractional CFO or financial advisor can build a rolling 13-week cash flow model — the most effective tool for preventing liquidity crises.
