What is Customer Acquisition Cost (CAC) in SaaS?
Customer Acquisition Cost (CAC) is the total cost a SaaS company spends to acquire a new customer, including marketing, sales, onboarding, and related expenses.
It helps measure how efficiently a company is attracting and converting customers.
Why Does CAC Matter for SaaS Companies?
CAC is important because it:
- Determines the cost-effectiveness of marketing and sales efforts
- Supports profitability and growth planning
- Helps compare the cost of acquiring customers to their lifetime value (LTV)
- Guides budget allocation for campaigns and sales initiatives
- Informs pricing and revenue strategy
A low CAC relative to LTV indicates efficient growth, while a high CAC may signal overspending on acquisition.
How is CAC Calculated in SaaS?
The formula for Customer Acquisition Cost is:
Example:
- Total marketing & sales spend: $100,000
- New customers acquired: 200
- CAC = 100,000 ÷ 200 = $500 per customer
What Factors Influence CAC in SaaS?

How Can SaaS Companies Optimize CAC?

What Are Common Mistakes in Calculating CAC?
