What is CLV:CAC Ratio in SaaS?
The CLV:CAC Ratio is the relationship between Customer Lifetime Value (CLV) and Customer Acquisition Cost (CAC).
It measures how efficiently a SaaS company is acquiring customers relative to the revenue they generate over their lifetime.
Why Does CLV:CAC Ratio Matter for SaaS Companies?
The CLV:CAC Ratio is important because it:
- Indicates the profitability of acquiring customers
- Guides marketing and sales spending decisions
- Helps identify whether growth is sustainable
- Supports investor evaluation and business valuation
- Highlights the balance between acquisition cost and long-term revenue
Rule of thumb:
- CLV:CAC = 3: Ideal balance (spend $1 to earn $3 in lifetime value)
- CLV:CAC < 1: Unsustainable (acquisition costs exceed revenue)
- CLV:CAC > 5: May indicate under-investment in growth
How is CLV:CAC Ratio Calculated in SaaS?
Example:
- CLV: $1,800
- CAC: $600
- CLV:CAC Ratio = 1,800 ÷ 600 = 3
This means for every $1 spent to acquire a customer, the company expects $3 in revenue over the customer’s lifetime.
