Use one documented boundary
Choose the period, included costs and outcome definition before comparing the result across campaigns or teams.
CAC calculator
Calculate customer acquisition cost from the spend you include.
Compare acquisition cost for new customers with a blended view that also counts reactivated customers.
Where the work changes.
Treat the output as a decision input
A calculator makes assumptions visible. It does not replace attribution quality, margin context or direct account review.
Questions before the audit.
- What costs belong in CAC?
- Include the sales and marketing costs your team has agreed are attributable to acquisition, then keep that boundary consistent across comparisons.
- Why show blended CAC?
- A blended view includes reactivated customers and can explain why a total acquisition program looks different from new-customer acquisition alone.
- Is a lower CAC always better?
- No. Customer value, margin and payback determine whether a lower acquisition cost represents useful growth.
Calculate from your numbers.
New CAC equals marketing plus sales spend divided by new customers. Blended CAC divides the same spend by new plus reactivated customers.
Review what is inside your CAC.
We will trace the spend, customer definition and campaign evidence behind the number.
