In the process
Frequently asked
What is the CAC payback period?
It is the amortization period of customer acquisition costs. It measures at what point a new customer has recouped the cost of their acquisition.
How do you calculate the CAC payback period?
You divide the customer acquisition cost by the monthly gross profit per new customer. The result is the payback period in months.
Is a short payback period always good?
Not automatically, because customer quality, churn and scalability also count. A fast amortization is of little use if customers soon leave again.
