How to Calculate Your True Customer Acquisition Cost

Customer Acquisition Cost (CAC) seems straightforward: total sales and marketing spend divided by new customers. But most businesses are calculating it wrong, leading to poor decisions and wasted budgets.

The real cost of acquiring a customer includes much more than just ad spend. Here's how to calculate your true CAC and use it to make better business decisions.

What Most Businesses Miss

Traditional CAC calculations often ignore:

- Sales team salaries and commissions
- Marketing team time and tools
- Content creation and design costs
- Software and tool subscriptions
- Event and conference costs

The True CAC Formula

True CAC = (Sales + Marketing + Overhead) ÷ New Customers Acquired

This gives you a complete picture of what each customer actually costs to acquire.

Why This Matters

Accurate CAC helps you:

- Set realistic growth targets
- Optimize your sales and marketing mix
- Make better hiring decisions
- Improve your unit economics

Hidden Costs to Include

How to Use True CAC

Once you have accurate CAC numbers:

1. Compare to Customer Lifetime Value (LTV)
2. Set realistic growth budgets
3. Optimize your sales and marketing mix
4. Make data-driven hiring decisions

The Bottom Line

Most businesses are spending 2-3x more on customer acquisition than they think. By calculating true CAC, you can make better decisions about where to invest your growth budget and how to scale efficiently.
