Formula Used
Blended CAC = Total Acquisition Costs ÷ Number of New Customers
- Total Acquisition Costs = Sum of channel spend ± optional fixed costs such as salaries tools and overhead.
- Paid CAC = Sum of spend from channels tagged as paid ÷ Customers from those same paid channels.
- Payback Period = Blended CAC ÷ ARPU (if ARPU provided).
Note: Ensure customers represent new customers acquired in the selected period not trials or signups unless that matches your definition.
