This B2B funnel produces a CAC of $500.00 with higher costs but better conversion quality than many lower-touch funnels.
How to Read Your Results
Compare CAC against your own historical performance, not a generic benchmark.
Review cost per lead together with lead-to-customer rate to avoid judging lead quality from CPL alone.
A rising CAC can come from higher spend, weaker conversion, or both.
Lead qualification rate helps identify whether the problem starts near the top of the funnel.
Use the same time period and attribution method when comparing examples to your own data.
Assumptions & Important Notes
- All costs and funnel counts refer to the same reporting period.
- Only direct acquisition-related costs are included.
- Each new customer is counted once.
- Lead and qualified lead definitions remain consistent across examples.

Frequently Asked Questions
What do these CAC examples help me understand?
They show how different cost levels and conversion rates can change customer acquisition cost and cost per lead.
Why can two funnels with similar cost per lead have very different CAC?
Because CAC depends heavily on how many leads eventually become customers, not just how cheaply leads are generated.
Is a higher qualified lead rate always better?
Usually it suggests better lead quality, but it still needs to lead to customer conversions to improve CAC.
Why does the B2B example have a higher cost per lead?
It includes heavier sales involvement, which raises total acquisition costs per lead.
Can I use these examples for weekly or quarterly planning?
Yes, but keep all inputs within the same time period for meaningful results.
