What Is Operating Cash Flow?

Operating cash flow (OCF) is the actual cash generated—or consumed—by your core business operations, excluding investment and financing activities. It's one of the three sections of a cash flow statement and is often considered the most reliable indicator of business health because it strips away non-cash accounting items (like depreciation) and focuses on real cash movement.

A company can show strong net income on an income statement yet have negative operating cash flow if it's not collecting from customers quickly or if it's building inventory. Conversely, OCF can be positive even during unprofitable periods if working capital is shrinking. Investors and lenders trust OCF because it's harder to manipulate than profit figures.

Formula

Operating Cash Flow = Net Income + Depreciation/Amortization − Change in Accounts Receivable − Change in Inventory + Change in Accounts Payable − Other Adjustments

(The specific adjustments depend on your accounting method; accrual-basis businesses need more adjustments than cash-basis.)

Example

A retail business reports $30,000 in net income for the quarter. It also recorded $2,000 in depreciation (a non-cash expense added back). Meanwhile, accounts receivable grew by $8,000 (customers haven't paid yet), inventory increased by $10,000, and the business reduced accounts payable by $5,000 (it paid suppliers faster, which uses cash rather than freeing it up). Operating cash flow = $30,000 + $2,000 − $8,000 − $10,000 − $5,000 = $9,000. Despite solid net income, OCF is far lower because cash is tied up in inventory and receivables, and the business is also paying down suppliers more quickly.
