What is Customer Acquisition Cost (CAC)?

CAC is the total cost of sales and marketing divided by the number of new customers acquired. Formula: CAC = (Marketing Spend + Sales Costs) ÷ New Customers

What is a good CAC?

A LTV:CAC ratio of 3:1 or higher is generally considered healthy for B2B businesses. Below 2:1 means you're spending too much to acquire customers relative to what they're worth.

How can a CRM lower your CAC?

  • Faster follow-up — automated reminders mean no lead waits more than a few hours for a response.
  • Better pipeline visibility — you close more deals by knowing exactly where every prospect stands.
  • Attribution data — custom reports show which channels actually produce customers.

Want to reduce your CAC?

A custom CRM built around your sales process can cut CAC by 20–40% through faster follow-up and better attribution. Let's talk.
