Operating Cash Flow Calculator (Indirect Method)
The indirect method starts from net income and adjusts for non-cash items and working-capital movements to arrive at operating cash flow (OCF) — the cash actually generated by a company's core business. Enter net income, D&A, and the change in net working capital to get OCF instantly.
Cash generated by core operations (indirect method)
- 1
Net income
800,000 - 2
Add D&A (non-cash add-back)
800,000 + 150,000 = 950,000 - 3
Subtract ΔNWC
950,000 − 50,000 = 900,000A rise in working capital uses cash and reduces OCF. - 4
Add other adjustments → OCF
900,000 + 0 = 900,000
How does this calculator work?
OCF (indirect) = Net Income + Depreciation & Amortisation − Change in Net Working Capital + Other non-cash items. It converts accrual profit to actual cash generated by operations. Positive OCF means the business funds itself; compare OCF to net income to gauge earnings quality — large divergence often signals accruals risk.
Formula
How this is calculated
Operating cash flow (OCF) measures the cash generated or consumed by a company's core business activities, stripping out financing and investing decisions. The indirect method — the form most companies use in their cash flow statement — starts with accrual-basis net income and reverses non-cash items and changes in working capital to convert it to cash.
Depreciation and amortisation (D&A) are added back because they reduce accounting profit but involve no actual cash outflow. A rise in net working capital (current assets minus current liabilities) uses cash — inventory bought but not yet sold, or receivables outstanding — so the change in NWC is subtracted; a fall in NWC provides cash and is added. Other common non-cash adjustments include stock-based compensation, deferred tax movements, impairment charges and gains/losses on asset disposals — enter these net as a positive (adds to OCF) or negative (reduces OCF).
Positive OCF is the hallmark of a financially healthy business; it means the company does not need external financing just to sustain day-to-day operations. Consistently comparing OCF to net income reveals earnings quality: OCF significantly below net income may indicate aggressive revenue recognition or growing receivables.
Frequently asked questions
Depreciation reduces accounting profit on the income statement but is a non-cash charge — no money actually leaves the business. Adding it back converts accrual profit toward a cash basis. The same logic applies to amortisation of intangibles, impairment write-downs, and any other non-cash expenses.
An increase in net working capital means the company is holding more current assets (e.g., inventory, receivables) or fewer current liabilities — all uses of cash. For example, if accounts receivable grows, the business has booked revenue but hasn't yet collected the cash; OCF is lower than net income by that amount. A decrease in NWC is the reverse: the company collected cash faster or stretched payables.
Operating cash flow is the cash from the business before capital expenditures. Free cash flow (FCF) = OCF − Capital Expenditures. FCF is the cash available to pay down debt, return to shareholders, or reinvest after maintaining and growing the asset base. A company with high OCF but very high capex may have little or even negative FCF.
