1. What is a SaaS CAC Calculator?

Definition: This calculator determines the Customer Acquisition Cost (CAC) for SaaS businesses by dividing total acquisition costs by the number of customers acquired.

Purpose: It helps SaaS companies measure the effectiveness of their marketing and sales efforts by calculating how much it costs to acquire each customer.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( CAC \) — Customer Acquisition Cost (USD)
• \( C \) — Total acquisition costs (USD)
• \( N \) — Number of customers acquired (dimensionless)

Explanation: The total marketing and sales costs are divided by the number of new customers gained during the same period.

3. Importance of CAC Calculation

Details: CAC is a critical SaaS metric that helps businesses understand their marketing efficiency, profitability, and scalability potential.
