Operating Cash Flow Calculator
Calculate Operating Cash Flow using Net Income, non-cash expenses and working-capital changes with a simplified indirect-method cash flow formula.
Use this calculator to estimate Operating Cash Flow using a simplified indirect method. Start with Net Income, add back non-cash expenses, then adjust for changes in operating assets and liabilities. Enter all amounts for the same accounting period and in one currency. Dollar signs are illustrative; currencies are not converted. For account changes, enter a positive value for an increase and a negative value for a decrease.

Estimate Operating Cash Flow using a simplified indirect method and signed changes in operating accounts.
Operating Cash Flow Example
Static example using the simplified indirect method: Net Income $100,000 + Depreciation $20,000 + Amortization $10,000 − Accounts Receivable increase $20,000 − Inventory increase $10,000 + Accounts Payable increase $15,000 = $115,000 Operating Cash Flow. This informational example is not calculated from current form inputs.
About this calculator
What Is Operating Cash Flow?
Operating Cash Flow (OCF), also called cash flow from operations, estimates cash generated or used by operating activities during a period. This simplified indirect-method calculation starts with Net Income and adjusts for selected non-cash expenses and operating balance changes.
Operating Cash Flow Formula
OCF = Net Income + Depreciation + Amortization + Other Non-Cash Expense Add-Backs − Change in Accounts Receivable − Change in Inventory − Change in Other Operating Assets + Change in Accounts Payable + Change in Other Operating Liabilities.
How to Enter Signed Account Changes
Enter a positive balance change when an account increased during the period and a negative balance change when it decreased. For operating assets, an increase generally reduces OCF and a decrease generally increases it. For operating liabilities, an increase generally increases OCF and a decrease reduces it. The calculator applies these cash-flow signs for you.
Why Does the Indirect Method Start With Net Income?
The indirect method reconciles accrual-based Net Income with operating cash flow by adjusting for non-cash expenses and changes in operating assets and liabilities. The entered fields model only selected adjustments; this is not a complete cash-flow statement.
Why Add Back Depreciation and Amortization?
Depreciation and amortization reduce accounting earnings but generally are not current-period cash payments in the same way as ordinary operating expenses. If included in Net Income, these non-cash expenses are added back in this simplified calculation.
How Do Receivables Affect Cash Flow?
An increase in Accounts Receivable generally means more sales have not yet been collected, tying up operating cash. A decrease generally releases cash, all else equal. Enter increases as positive and decreases as negative.
How Does Inventory Affect Cash Flow?
An increase in Inventory generally uses operating cash, while a decrease generally releases cash, all else equal. Enter increases as positive and decreases as negative.
How Does Accounts Payable Affect Cash Flow?
An increase in Accounts Payable generally delays a cash payment and temporarily supports operating cash flow; a decrease generally represents payments using cash. This is a timing effect, not profit. Enter increases as positive and decreases as negative.
Operating Cash Flow vs. Net Income
Net Income is an accounting earnings measure. Operating Cash Flow adjusts Net Income for non-cash expenses and changes in operating assets and liabilities, so the two measures can differ materially. See the live Net Profit Margin Calculator for an earnings-to-sales measure; it is not an OCF calculation.
Operating Cash Flow vs. EBITDA
EBITDA is an earnings measure that excludes interest, taxes, depreciation and amortization. Operating Cash Flow is affected by working-capital changes and cash timing. EBITDA is not Operating Cash Flow. See the live EBITDA Margin Calculator for the separate margin measure.
Operating Cash Flow vs. the Cash Flow Calculator
This Tool estimates financial-statement Operating Cash Flow from Net Income using selected indirect-method adjustments. The separate Cash Flow Calculator plans cash inflows and outflows for a period or across monthly projections. Use that planning Tool when you need projected cash balances, not a Net Income reconciliation.
Operating Cash Flow vs. Free Cash Flow
Free Cash Flow generally starts with Operating Cash Flow and subtracts Capital Expenditures. This Operating Cash Flow calculator does not calculate that separate measure.
Working-Capital Effects
Operating asset increases such as receivables and inventory generally use cash; decreases generally release cash. Operating liability increases such as payables generally provide a temporary source of operating cash; decreases generally use cash. These changes are not themselves profit.
Use Consistent Accounting Periods
All inputs should cover the same accounting period. For annual Net Income, use annual depreciation and amortization and operating-account changes from the beginning to the end of that same year. Use consistent accounting classifications and balance-sheet dates.
Positive, Zero and Negative Operating Cash Flow
Positive OCF means the entered operating activities and adjustments generated net operating cash for the period; it does not establish financial health. Negative OCF means they used net operating cash; it does not establish insolvency or failure. Zero OCF means the entered amounts net to zero. Net Income and operating cash flow can have different signs.
Operating Cash Flow and Financial Health
OCF answers a different question from profitability, working-capital, leverage and liquidity measures, and should not be used alone to judge financial health. It can eventually be considered alongside Free Cash Flow, debt servicing and other contextual metrics; this calculator does not score a business or make financing recommendations.
Frequently asked questions
What is Operating Cash Flow?
Operating Cash Flow estimates cash generated or used by operating activities during a period. This Tool uses a simplified indirect method.
How do you calculate Operating Cash Flow?
Start with Net Income, add back eligible non-cash expenses and adjust for selected operating asset and liability changes using their cash-flow effects.
What is the indirect method?
The indirect method reconciles Net Income to operating cash flow by adjusting for non-cash expenses and balance changes in operating assets and liabilities.
Is Operating Cash Flow the same as Net Income?
No. Net Income is an accounting earnings measure; Operating Cash Flow adjusts it for non-cash expenses and selected working-capital changes.
Is Operating Cash Flow the same as EBITDA?
No. EBITDA is an earnings measure; Operating Cash Flow also reflects working-capital changes and cash timing.
Why is depreciation added back?
Depreciation reduces accounting earnings but generally is not a current-period cash payment in the same manner as an ordinary operating expense.
How does Accounts Receivable affect Operating Cash Flow?
An increase in receivables generally uses cash; a decrease generally releases it, all else equal.
How does Inventory affect Operating Cash Flow?
An increase in inventory generally uses cash; a decrease generally releases it, all else equal.
How does Accounts Payable affect Operating Cash Flow?
An increase in payables generally delays cash payment and temporarily supports OCF; it is a timing effect, not profit.
Can Operating Cash Flow be negative?
Yes. Entered operating activities can use more cash than they generate; negative OCF does not by itself imply insolvency.
What is the difference between Operating Cash Flow and Free Cash Flow?
Free Cash Flow generally starts with OCF and subtracts Capital Expenditures. This Tool calculates Operating Cash Flow, not Free Cash Flow.
Is positive Operating Cash Flow always good?
Not automatically. Positive OCF describes the entered period but does not alone establish financial health, sustainability or profitability.
This is a simplified indirect-method calculation, not a formal cash-flow statement. Actual statements can contain additional adjustments, and accounting classifications may vary. Results depend on user-entered information; use the same accounting period and consistent beginning and ending balance data. Positive OCF does not by itself establish financial health; negative OCF does not by itself establish financial distress.
