Indirect-method calculation for a single period. Figures are rounded to the nearest dollar. Check the result against your statement of cash flows before reporting it externally.
Methodology
A simple model with visible math.
Start with net income
Pull net income straight from the bottom of the income statement.
Add back non-cash expenses
Depreciation and amortization reduced net income but never moved cash.
Adjust working capital
Subtract increases in inventory and receivables, add increases in payables.
Add remaining accruals
Income tax payable and other non-cash items such as deferred revenue.

What is operating cash flow?
Operating cash flow (OCF) is the actual cash a business generates from its core operating activities, day-to-day sales, payments to suppliers, payroll, and collections, before any investing or financing activity is factored in.
It's a more reliable read on financial health than net income, because it strips out non-cash accounting items like depreciation.
How to calculate operating cash flow
Most businesses use the indirect method, since it starts from numbers you already have on the income statement and balance sheet.
- 1
Get net income from the income statement.
- 2
Add back depreciation and amortization, since neither one is an actual cash outflow.
- 3
Adjust for the change in working capital: subtract increases in inventory and accounts receivable, add increases in accounts payable.
- 4
Add any income tax payable that has not been paid out in cash yet.
- 5
Add other non-cash items, such as deferred revenue or stock-based compensation.
In short: operating cash flow = net income + non-cash expenses + changes in working capital. The calculator above runs this exact calculation, so you can enter your own figures or use the built-in example to see it applied to real numbers.
Reading changes in working capital
| Account | Increase | Decrease |
|---|---|---|
| Inventory | Cash outflow (use) | Cash inflow (source) |
| Accounts receivable | Cash outflow (use) | Cash inflow (source) |
| Accounts payable | Cash inflow (source) | Cash outflow (use) |
How increases and decreases in working capital accounts affect operating cash flow.
Why it matters
Why operating cash flow matters more than net income
A profitable business can still run out of cash. OCF is the number that shows whether operations are actually generating money, not just booking it.
Spotting trouble before it shows up elsewhere
- Negative OCF alongside positive net income is an early warning sign
- Rising receivables can mask a collections problem for months
- OCF trends often move before earnings per share does
Judging real operational health
- Excludes one-time investing or financing activity
- A useful input for interest coverage and cash flow to debt ratios
- Growing OCF supports reinvestment without new debt or equity

You need OCF for the cash flow statement and to explain any gap between it and net income to leadership.
Funding growth
You're deciding whether operations can fund growth without new financing, and OCF trend is the number that answers it.
Owning the payables lever
Accounts payable timing is one of the few working capital levers your team directly controls, and it shows up straight in this formula.
