About this tool
Enter total sales and marketing spend for a period and the new customers won in that period, and the tool gives cost per customer. This is an estimate from your own totals, not an industry benchmark, and it is only useful when spend and customers cover the same period.
Frequently asked questions
What period should I use?
Use one month or one quarter, and keep spend and new customers in the same period.
What is a good CAC?
There is no universal good figure. Compare it with what a customer is worth to you over their lifetime.
