Interpretation
Change one assumption at a time and identify where the system is most sensitive.

Revenue without margin, sales-cycle time and service cost does not show true return.
FAQ
Frequently asked questions
What should count as a lead?
Use one stable event: a relevant form submission, qualified call, confirmed registration or another step the team genuinely processes.
Why will the result differ from actual revenue?
The model does not include seasonality, stage delays, repeat business, refunds, margin or segment differences. It is designed to test funnel logic and sensitivity.
How should reverse calculation be used?
Enter target revenue and realistic conversion rates. The resulting top-of-funnel volume indicates the order of demand required. Then test whether the market and team can support it.
