General questions
Basic questions about what the calculator does and when to use it.
What does a sales funnel ROI calculator measure?
It estimates leads, customers, revenue, net profit, ROI, cost per lead, and customer acquisition cost from your funnel inputs.
Who can use a sales funnel ROI calculator?
It can be used by marketers, founders, sales teams, and business operators who want a simple estimate of funnel efficiency.
Can this calculator be used for both B2B and B2C funnels?

Is the result an exact forecast?
No. It is an estimate based on the assumptions and averages you enter.
Formula and calculation questions
Questions about how the calculator turns inputs into outputs.
How are leads calculated?
Leads are calculated as monthly visitors multiplied by the visitor-to-lead conversion rate.
How are customers calculated?
Customers are calculated as leads multiplied by the lead-to-customer conversion rate.
How is revenue calculated?
Revenue is estimated by multiplying customers by average revenue per customer.
How is ROI calculated?
ROI is calculated as ((revenue - total cost) / total cost) × 100.
What is customer acquisition cost in this calculator?
Customer acquisition cost is total monthly funnel cost divided by estimated customers.
Accuracy and assumptions
Questions about what may affect reliability and how to interpret the numbers.
Why might actual results differ from the estimate?
Real performance can vary because of traffic quality, seasonality, sales cycle timing, pricing changes, and attribution differences.
Does the calculator include refunds or churn?
Not automatically. Those factors are only reflected if you build them into your revenue assumptions.
Does it account for repeat purchases or lifetime value?
Only if your average revenue per customer input includes those amounts.
Why can ROI be negative?
ROI is negative when estimated revenue is lower than the total monthly cost.
Inputs and results
Questions about what to enter and how to read the outputs.
What costs should be included?
Include monthly marketing and sales costs directly tied to generating and closing funnel opportunities.
Should I use monthly or annual data?
Use one time period consistently. If visitors are monthly, revenue and costs should also be monthly.
What does cost per lead tell me?
It shows the average total cost to generate one lead and helps compare lead generation efficiency.
What does a high ROI mean?
It means the funnel is generating a relatively large profit compared with the cost used to run it.
