What Is CAC (Customer Acquisition Cost)?
Customer Acquisition Cost (CAC) measures the average cost of acquiring a new customer. It’s a key metric to understand the efficiency of your marketing and sales efforts.
Unlike revenue-focused metrics, CAC shines a light on your investment per customer, helping you assess profitability, scalability, and long-term growth potential.
High CAC doesn’t always mean there’s an issue. It could also reflect strategic investment in high-value customers, but consistent monitoring ensures your marketing spend is generating bright, sustainable returns.
How to Calculate CAC
The CAC calculation formula is straightforward:
CAC = Total Sales & Marketing Spend ÷ Number of New Customers Acquired
For example: if your business spent €5,000 on marketing and gained 100 new customers, your CAC is:
CAC = €5,000 ÷ 100 = €50 per customer
Tracking CAC over time allows you to spot trends, identify high-cost channels, and make data-driven decisions to optimize customer acquisition strategies.
Why CAC Matters
Customer Acquisition Cost is not just a number, it’s a guiding light for sustainable growth. By understanding CAC, you can:
- Allocate budgets more effectively across channels.
- Identify which campaigns and strategies deliver the most value.
- Balance acquisition cost against customer lifetime value (CLV) for profit-driven growth.
- Illuminate areas where efficiency can be improved and revenue can be maximized.
Consistently monitoring CAC ensures your campaigns remain both cost-effective and high-performing, helping you grow your business without wasting resources.

Frequently Asked Questions
Let our FAQ section illuminate the path to improving your CAC.
How do you calculate CAC?
Divide your total sales and marketing spend by the number of new customers acquired. Example: €10,000 ÷ 200 = €50 CAC.
What is a good CAC?
A good CAC depends on your industry, business model, and customer lifetime value (CLV). Lower CAC is generally better, but the goal is profitable growth rather than the lowest possible cost.
Does CAC include all marketing spend?
Yes. Include advertising costs, sales team expenses, marketing campaigns, and any other investment directly linked to acquiring customers.
Why is CAC important?
It helps you understand the efficiency of your marketing, plan budgets wisely, and ensure that acquisition strategies are sustainable over time.
Can CAC be reduced without lowering revenue?
