TL;DR: Operating cash flow is the net cash generated by a company core operations in a period. Illustrative example only: a company reports net income of $240,000, adds back depreciation of $60,000, subtracts a $25,000 increase in accounts receivable, adds a $10,000 decrease in inventory, and adds a $15,000 increase in accounts payable. That gives $300,000, since $240,000 plus $60,000 minus $25,000 plus $10,000 plus $15,000 equals $300,000. Profit is an accounting measure. Operating cash flow is cash.

Start from net income, then adjust for cash
All figures in this section are illustrative. Net income is calculated under accounting rules that include non cash charges and timing differences. Operating cash flow, usually taken from the cash flow statement, strips those effects back out to show the cash the core business actually produced. The standard reconciliation starts with net income and adjusts it in two groups in this simplified example, which assumes no other adjustments.
First, add back non cash charges. Depreciation of $60,000 reduced net income but no cash left the business for it in this period, so it is added back. Second, adjust for working capital changes. Accounts receivable rose by $25,000, meaning $25,000 of recorded sales had not yet been collected in cash, so it is subtracted. Inventory fell by $10,000, meaning the business sold goods already on hand rather than buying replacements in the period, so $10,000 is added. Accounts payable rose by $15,000, meaning $15,000 of costs had been recorded but not yet paid, so it is added. Real filings can carry further adjustments, such as removing gains or losses on asset sales that belong in the investing or financing sections. The result here is $300,000 of operating cash flow, which is higher than net income of $240,000 in this example.
How is operating cash flow different from net income and free cash flow?
Net income, covered in what is net income, is profit after all expenses, including non cash ones. Operating cash flow can be higher or lower than net income in any single period, and a gap between them is not automatically good or bad. A fast growing company often shows operating cash flow below net income because receivables grow with sales. A company collecting old invoices can show the reverse.
Free cash flow goes one step further. As what is free cash flow explains, it subtracts capital expenditure, maintenance and expansion spending alike, from operating cash flow to show cash left after maintaining and growing the asset base. Operating cash flow itself does not subtract that spending, nor does it include cash from borrowing, repaying debt, issuing shares, or buying and selling investments. Once capital expenditure is subtracted, the result is the free cash flow priced per share in price to free cash flow explained. Those sit in the financing and investing sections of the cash flow statement. Reading all three sections together is what gives the full picture.
What to look for when you use it
Compare operating cash flow with net income over several periods, not one. A business that reports rising profit year after year while operating cash flow stays flat is asking investors a question worth investigating, because earnings that never turn into cash need an explanation. Also check the working capital moves. One period of rising receivables may be growth. Repeated rises paired with management commentary that never mentions collections deserve scepticism.
Operating cash flow is also the starting point for cash based valuation work and for judging whether dividends and buybacks are funded by the business itself. It is not a complete quality score on its own, and it can be flattered in a single period by delaying payments to suppliers, which reverses later. Use it as a cash reality check alongside the income statement, not as a replacement for it.
