Cash flow statement explained: operating, investing and financing cash

Why the cash flow statement matters

The cash flow statement explains why cash changed during a period. It separates operating activity from investment and financing decisions, helping readers distinguish cash generated by the core business from cash raised through borrowing or asset sales.

Operating cash flow

Operating activities include cash collected from customers and cash paid for suppliers, employees, taxes and other operating costs. Under the indirect method, the statement starts with profit and adjusts for non-cash expenses and movements in working capital. An increase in receivables, for example, uses cash because recognized revenue has not yet been collected.

Investing cash flow

Investing activities commonly include purchases and sales of equipment, long-term assets and investments. Negative investing cash flow is not automatically bad: it may reflect deliberate investment in capacity. The question is whether the investment is affordable and expected to create value.

Financing cash flow

Financing activities include borrowing, debt repayment, owner contributions, share issues and distributions. A business can report positive total cash flow while operations consume cash if new financing fills the gap.

Reconcile the movement

Opening cash + net cash movement = closing cash

Closing cash should reconcile to the relevant bank and cash balances on the balance sheet. Differences often indicate omitted accounts, duplicated entries or classification mistakes.

Turn history into a forecast

Historical cash flow explains what happened; a forecast estimates what may happen next. Start by separating committed from variable payments and applying realistic collection timing. Try the cash flow forecast calculator, then read the cash flow forecasting guide for a recurring process.
