What is Cash Flow Analysis?
Cash flow analysis examines how cash moves through a company's operating, investing, and financing activities to assess liquidity and the quality of reported earnings. Because net income relies on accruals and estimates, comparing it to actual operating cash flow reveals whether profits are backed by real cash. A low quality-of-earnings ratio is a classic red flag for aggressive accounting.
Cash flow analysis evaluates a company's cash generation and the quality-of-earnings ratio, QoE = Operating Cash Flow ÷ Net Income, where a ratio near or above 1 signals that reported profits are backed by real cash.

Step-by-step worked examples
A company reports net income of $350,000 and operating cash flow of $420,000. Compute the quality of earnings ratio and interpret it.
QoE = Operating Cash Flow ÷ Net Income QoE = 420,000 ÷ 350,000 QoE = 1.2, meaning cash flow exceeds reported profit — high quality earnings
A company reports net income of $500,000 but operating cash flow of only $150,000. What does this suggest?
QoE = 150,000 ÷ 500,000 = 0.3 A ratio well below 1 suggests profits are not backed by cash Possible causes: aggressive revenue recognition, rising receivables, or inventory buildup — warrants further investigation
Operating cash flow is $200,000, investing activities use $150,000 for equipment, and financing activities include $50,000 of debt repayment. What is the net change in cash?
Net change in cash = Operating CF + Investing CF + Financing CF Net change = 200,000 + (−150,000) + (−50,000) Net change = $0 — cash balance stayed flat this period
