FAQ

Customer acquisition cost questions answered

What costs should I include in CAC?+
Include ALL marketing and sales expenses: ad spend, marketing salaries, sales commissions, software subscriptions (CRM, marketing automation), agency fees, creative production, and allocated overhead. Exclude product development and G&A.
What's a healthy LTV:CAC ratio?+
Target LTV:CAC > 3x. Below 3x means you're spending too much to acquire customers. Between 3x-5x is healthy. Above 5x means you may be under-investing in growth. SaaS investors look for >3x.
What's a good CAC payback period?+
Payback period = CAC / (Monthly ARPU × Gross Margin). Best-in-class SaaS: <12 months. Acceptable: 12-18 months. Concerning: >24 months. Longer payback strains cash flow.
How do I calculate CAC by channel?+
Channel CAC = Total spend on that channel / New customers from that channel. Include channel-specific salaries, ad spend, and tools. Our calculator does this for 10+ channels automatically.
What's the difference between CAC and CPA?+
CPA (Cost Per Acquisition) typically refers to ad platform cost per conversion. CAC includes ALL marketing and sales costs — salaries, software, overhead. CAC is always higher than CPA.
How does CAC vary by business model?+

How often should I calculate CAC?+
