Quick answer
How do you calculate Cash Flow?
Use Net cash flow = Cash inflows − Cash outflows. Enter the matching values above to calculate the result instantly.
What it measures
Understanding Cash Flow
Calculate net cash flow by subtracting cash outflows from cash inflows. Unlike accounting profit, cash flow tracks money that actually moved, so unpaid invoices and non-cash expenses can make the two measures differ.
Interpretation
What the result means
A positive result means more cash entered than left during the period; a negative result means operations or financing consumed cash.
Action
How to use it
Use it in a rolling cash forecast and investigate the timing of large receipts, payroll, tax, debt, and inventory payments.
Limits
What it leaves out
This simple measure does not separate operating, investing, and financing cash flows or show the opening cash balance.

Common questions
Frequently asked questions
Which inputs should I use for Cash Flow?
Use cash inflows, cash outflows, measured from the same source and period. Include only values that match the definitions shown beside each field.
Why might two Cash Flow calculations differ?
The systems or accounting policies may define cash inflows, cash outflows differently. Compare the time period, scope, source, and treatment of exceptional items before comparing results.
How often should I recalculate Cash Flow?
Recalculate when any input changes materially and on the same reporting cadence used for the decision. Save the source and date of each input so the trend remains comparable.
Can I use Cash Flow by itself?
No single metric captures the full decision. Use the result with the related measures, assumptions, and limitations shown on this page.
