Operating Cash Flow
Last reviewed 2026-05-11 by Asad Ali, Founder & CEO
Cash generated from core business operations.
Operating cash flow (OCF) measures the cash a business generates from its normal operating activities, excluding investing and financing activities. It is the first major section of the statement of cash flows under FASB ASC 230. Under the indirect method (used by most US companies), OCF starts with net income and adjusts for non-cash items (depreciation, amortization, stock-based compensation, deferred taxes) and changes in working capital (accounts receivable, inventory, accounts payable, accrued expenses). Under the direct method, it lists cash collected from customers minus cash paid to suppliers, employees, and tax authorities. Consistently positive OCF is the strongest signal of a fundamentally sound business — a company can manage temporary net losses, but persistent negative OCF leads to bankruptcy.
Formula
OCF (Indirect Method) = Net Income + Non-cash Expenses (Depreciation, Amortization) ± Changes in Working Capital (AR, Inventory, AP, Accrued Expenses)Example
A retail store reports $30,000 net income. Adjustments: add back $10,000 depreciation (non-cash); accounts receivable decreased $4,000 (customers paid down balances) so add $4,000; inventory increased $7,000 (cash tied up in stock) so subtract $7,000; accounts payable increased $3,000 (deferred supplier payments) so add $3,000. OCF = $30,000 + $10,000 + $4,000 − $7,000 + $3,000 = $40,000. Even though net income was $30,000, the business actually generated $40,000 of cash from operations.
Why It Matters for Your Business
Operating cash flow reveals whether your core business generates enough cash to sustain itself, independent of loans or asset sales.
Practical Tips
- •Compare OCF to net income each quarter — large persistent gaps in either direction signal aggressive revenue recognition or working-capital problems
- •When OCF is negative but net income is positive, look at receivables and inventory first — those are usually where the cash is trapped
- •Lenders care more about OCF than net income for debt-service coverage — strong OCF makes loans easier and cheaper
- •Track OCF margin (OCF ÷ Revenue) — a ratio under 10% in mature businesses signals weak cash generation regardless of reported profits
Common Questions About Operating Cash Flow
