What is a customer acquisition cost (cac)?
Customer acquisition cost (CAC) estimates how much an organization spends to acquire each new customer during a defined period. Include the relevant marketing and sales costs and divide by new customers acquired in that same period. Consistent attribution and period boundaries are essential for a useful comparison.
Formula and calculation method
