How to Read Your Results
Compare cost per lead with your typical lead quality, not just with traffic volume.
Use cost per customer to judge acquisition efficiency across the full funnel.
Review revenue alongside total funnel cost to understand estimated profit potential.
ROAS focuses on ad spend only, so it should be read together with total funnel cost.
A low cost per lead does not always mean a profitable funnel if lead-to-customer conversion is weak.
Assumptions & Important Notes
- Each example uses the same time period for spend, visitors, leads, and customers.
- Conversion rates are treated as averages rather than exact outcomes for every campaign.
- Average order value reflects revenue per customer and excludes refunds or repeat purchase effects unless stated.
- Fractional customer estimates are shown for calculation clarity, although real customer counts are whole numbers.

Frequently Asked Questions
Why do some examples show fractional customers?
The calculator applies average conversion rates mathematically, so projected customer counts can be fractional even though real-world results are whole numbers.
Which example is most realistic?
That depends on your traffic quality, offer, sales process, and price point. The examples are meant to show different possible funnel patterns.
What should I focus on first in the results?
Most users start with cost per customer, total funnel cost, and estimated revenue because those metrics show efficiency and scale together.
Can the same funnel have a low cost per lead and a high cost per customer?
Yes. That usually happens when visitors become leads easily but only a small share of leads become paying customers.
