Operating Cash Flow Calculator for Business Cash
Calculate cash generated by core business operations with working-capital adjustments.

Operating cash flow = net income + depreciation and amortization + other non-cash expenses − taxes paid − change in receivables − change in inventory + change in payables.

About the Operating Cash Flow Calculator

Operating cash flow, often shortened to OCF, measures the cash a business generates or uses through its ordinary activities during a reporting period. It starts with an accrual-based profit figure and then adjusts that figure for items that affected accounting income without moving cash, plus movements in working-capital accounts. That distinction is important: a profitable business can still have weak operating cash flow when customers have not paid invoices or inventory has absorbed cash. The operating cash flow calculator follows the indirect-method layout shown in its formula. Add net income, depreciation and amortization, and other non-cash expenses. Subtract taxes paid, increases in accounts receivable, and increases in inventory. Add an increase in accounts payable because unpaid supplier balances preserve cash in the current period. Enter decreases as negative changes. For example, a $2,000 decrease in receivables is entered as −2,000, which increases the calculated cash flow. The result is useful for a quick operating-performance review. Managers can compare OCF with net income to see whether reported earnings are becoming cash. Lenders may examine it when considering debt-service capacity, while investors often follow its trend alongside capital expenditure and free cash flow. A single result is not a verdict on financial health; seasonal purchasing, a large collection cycle, or a one-time tax payment can materially change one period. Use amounts from the same accounting period and apply a consistent sign convention. This version treats taxes paid as a separate cash outflow because it is an explicit input in the supplied formula. In a formal cash-flow statement, the treatment of taxes and other adjustments should match the reporting framework and the way net income was defined. Reconcile unusual results to the underlying ledger, review receivable and inventory movements separately, and compare several periods before making a financing or investment decision. The calculator is an analytical aid, not a substitute for audited financial statements or professional accounting advice.

Income $40,000; depreciation $5,000; taxes $6,000; receivables $0; inventory $0; payables $0$39,000.00With no working-capital movement, non-cash depreciation is added back after the tax payment.

How to Use the Operating Cash Flow Calculator

  1. Enter net income for the period using the same currency for every amount.
  2. Add depreciation, amortization, and any other non-cash expenses to be added back.
  3. Enter taxes actually paid, not simply tax expense accrued.
  4. Enter the period-to-period change for receivables, inventory, and payables; use a negative number for a decrease.
  5. Select Calculate and review the result together with the movement in its underlying accounts.

Operating Cash Flow FAQ

What does a positive operating cash flow mean?

It means normal operations generated more cash than they used during the period under the inputs supplied. It does not by itself guarantee profitability, liquidity, or sustainable future cash flow.

Why are receivables subtracted?

An increase in receivables represents sales recognized in income that customers have not yet paid in cash. It therefore reduces cash relative to accrual-based net income.

How should I enter a decrease in inventory?

Enter it as a negative number. The formula subtracts the change in inventory, so subtracting a negative reduction correctly increases operating cash flow.

Is operating cash flow the same as free cash flow?

No. Free cash flow normally begins with operating cash flow and then subtracts capital expenditures and, depending on the definition, may include other adjustments.
