What is Cash Flow?

Cash flow is money coming in minus money going out. Positive cash flow means you have more coming in than going out. In corporate finance, the SEC requires public companies to publish a statement of cash flows, which categorizes cash movements into operating activities, investing activities, and financing activities. In personal finance, positive cash flow occurs when cash inflows (such as salary and investment income) exceed outflows (such as bills and debt payments), providing capital for wealth building.

Conversely, negative cash flow occurs when expenditures exceed income, resulting in cash depletion or debt accumulation. Analyzing cash flow differs from analyzing profitability, as cash flow tracks the timing of actual cash receipts and payments, which is critical for maintaining solvency and liquid reserves.

PRACTICAL EXAMPLE

A small business has $50,000 in monthly sales but operates on net 60-day payment terms. While profitable on paper, if it must pay $30,000 in monthly expenses immediately, its cash flow is negative during the collection period, requiring liquid cash reserves to maintain operations.
