operating cash flow
/ OCF /
Think of a lemonade stand at the end of the summer. Forget the paper accounting for a moment and ask one blunt question: after paying for lemons, sugar, cups, and the kid you hired, how much more cash is in the box than when you started — purely from selling lemonade? That number, the cash the core business itself throws off, is operating cash flow. It is the clearest single measure of whether a business pays for itself.
Operating cash flow is the net cash a company generates from its normal business operations during a period — the bottom line of the operating activities section of the cash flow statement. It can be presented two ways that always agree: the direct method (cash from customers minus cash to suppliers, employees, interest, and taxes) or the indirect method (net income adjusted for non-cash items and changes in working capital). If customers paid 480,000 and the business paid 410,000 to run itself, operating cash flow is 70,000.
It is one of the most-watched numbers in finance because, unlike profit, it is hard to dress up with estimates. Strong, growing operating cash flow signals a healthy engine; it is what funds new equipment, debt repayment, and dividends without needing outside money. It is also the starting point for free cash flow. A caveat: a single year can be distorted by timing — for instance, a one-off delay in paying suppliers can flatter operating cash flow — so it is best read over several periods.
Two companies each report 40,000 of net income, but Company A has operating cash flow of 55,000 and Company B has just 5,000. Company B's profit is mostly tied up in receivables and inventory — A is converting profit into cash far more effectively.
Same profit, very different cash — operating cash flow tells them apart.
Operating cash flow can be positive even in a year of net loss (depreciation and timing can outweigh the loss), and it can be negative in a profitable year — which is precisely why both numbers are reported.
