CAC (Customer Acquisition Cost) is how much, on average, it costs you to win a new customer. On its own it says little — what matters is comparing it to customer lifetime value (LTV).

The rule of thumb is an LTV:CAC ratio of at least 3:1. Below that, your growth is not sustainable.

Frequently asked questions

How is CAC calculated?

CAC = total sales and marketing spend in a period / number of new customers acquired in that same period.

What LTV:CAC ratio is healthy?

A common benchmark is 3:1 or higher. Below 1:1 you lose money per customer; far above 5:1 may mean you are underinvesting in growth.
