Frequently Asked Questions

What is customer acquisition cost (CAC)?
CAC is the total cost of acquiring a new customer, including all marketing and sales expenses divided by the number of customers acquired. CAC = (Marketing Spend + Sales Spend) / New Customers. It is one of the most important metrics for any business.
What is a good CAC payback period?
For SaaS: under 12 months is good, under 6 months is excellent. For e-commerce: ideally on the first purchase. B2B companies typically have longer payback (6-18 months). Venture-funded startups may accept 12-18 months; bootstrapped companies should target under 6 months.
How can I reduce my CAC?
Improve conversion rates at each funnel stage, optimize ad targeting, invest in organic/content marketing (lower long-term CAC), build referral programs, improve sales efficiency, reduce sales cycle length, and focus on higher-converting channels.
