How to Read Your Results
Revenue shows the estimated value created by new customers in the selected period.
Net profit is revenue minus the marketing and sales costs you included.
ROI tells you how large the profit is relative to total funnel cost, not just as a raw dollar amount.
Cost per lead and customer acquisition cost help you compare efficiency across channels or campaigns.
Assumptions & Important Notes
- Each example uses monthly traffic, monthly costs, and monthly revenue for consistency.
- Conversion rates are treated as stable averages across the period.
- Average revenue per customer is assumed to represent the value of new customers generated in that month.
- The examples do not include refunds, churn, or delayed revenue recognition unless reflected in the revenue figure.

Frequently Asked Questions
Why do some examples show fractional customers?
The calculator produces average estimates. In real life you cannot have part of a customer, but averages are useful for planning.
Which matters more: traffic or conversion rate?
Both matter, but a weak conversion rate can limit ROI even when traffic is high. The examples show how bottlenecks affect results.
Can a high-cost funnel still have good ROI?
Yes. If conversion quality and revenue per customer are strong enough, higher costs can still produce strong profit and ROI.
Why is a high-value B2B funnel different from a B2C funnel?
B2B funnels often have fewer customers but higher revenue per customer, while B2C funnels may rely more on larger volumes.
