Calculated from the sample figures using the displayed formula.
What is the operating cash flow formula?
Net income + Noncash expenses − Increase in working capitalThis reconciliation form of operating cash flow adjusts accrual net income for noncash expenses and working-capital changes.
What do the inputs mean?
- Net income
- The value entered for net income. Keep its period and units consistent with the other inputs.
- Depreciation and other noncash expenses
- The value entered for depreciation and other noncash expenses. Keep its period and units consistent with the other inputs.
- Increase in working capital
- The value entered for increase in working capital. Keep its period and units consistent with the other inputs.
How to calculate it step by step
- Define the decision.
Write down what the result will help you compare or decide. - Collect matching inputs.
Use figures from the same period and apply the definitions shown on this page. - Apply the formula.
Net income + Noncash expenses − Increase in working capital. - Check the units.
Confirm whether the result is a currency amount, percentage, number of periods or ratio. - Test a second case.
Change one assumption at a time to see what drives the result.
Worked example
Using the sample figures in the calculator, the result is $160,000.00. Change one figure at a time and recalculate to see which assumption has the greatest effect. A spreadsheet should return the same result when it uses the same formula, units and timing.
When should you use operating cash flow formula?
Use it to understand cash generated by core operations.
Limitations and common mistakes
A complete cash-flow statement includes every operating adjustment, not only the three inputs shown here.
Do not mix annual figures with monthly figures, ending balances with averages, or percentages with whole numbers. Record the definition used so another person can reproduce the result.
