Frequently Asked Questions (FAQs)
What costs should be included in CAC calculations?
You should include all sales and marketing expenses—such as ad spend, software subscriptions, salaries, agency fees, and promotional overhead—attributable to customer acquisition.
What is a good LTV to CAC ratio?
A healthy benchmark for many businesses is an LTV to CAC ratio of 3:1, meaning the value a customer brings over their lifetime is three times what it cost to acquire them.
How can I lower my Customer Acquisition Cost?
You can reduce CAC by improving conversion rate optimization (CRO), targeting higher-converting audience segments, enhancing organic marketing channels, and streamlining your sales funnel.
