CAC = Total S&M Spend / New Customers AcquiredAbout this tool
Customer Acquisition Cost (CAC) measures the total sales and marketing expenditure required to acquire a single new paying customer account. A common trap for software founders is calculating 'blended' or 'paid-only' CAC by dividing Google or Meta ad spend by total signups, completely omitting sales representative salaries, marketing agency retainers, and the software stack (HubSpot, ZoomInfo, Apollo) used to close those deals. True, fully loaded CAC includes all direct and overhead costs associated with customer acquisition. Knowing your exact fully loaded CAC ensures that paid growth initiatives are genuinely profitable and provides the baseline needed to calculate acquisition payback horizons. Use this calculator to determine your true fully loaded CAC.
How It Works
- 1Input your total sales and marketing expenditures during the period (advertising, sales salaries, marketing tools, agency fees).
- 2Input the total number of brand-new paying customer accounts acquired during that same period.
- 3Review your calculated fully loaded CAC per customer account.

Calculation / Steps
$27,000 / 90 = $300.00
