What is CAC
Customer Acquisition Cost (CAC) is the total cost your business incurs to acquire a new customer. It's one of the most important metrics for any business, especially those focused on growth.
CAC includes:
- Marketing costs (advertising, content, campaigns)
- Sales costs (salaries, commissions, tools)
- Related overhead directly tied to acquisition
How to Calculate CAC
The CAC formula is straightforward:
CAC = (Total Marketing Cost + Total Sales Cost) ÷ Number of New Customers
Practical Example
Suppose in one month:
- Marketing Cost: $15,000 (ads, content, tools)
- Sales Cost: $10,000 (team salaries, commissions)
- New Customers: 50
Calculation:
- Total Acquisition Cost = $15,000 + $10,000 = $25,000
- CAC = $25,000 ÷ 50 = $500 per customer
Why CAC Matters
1. Profitability Assessment
If your CAC is higher than what a customer generates in profit, you're losing money on growth.
2. Growth Strategy
Understanding CAC helps you:
- Decide which acquisition channels to scale
- Set realistic growth targets
- Allocate marketing budget effectively
- Evaluate campaign performance
3. Investor Confidence
Investors look at CAC to assess business sustainability. A healthy CAC relative to LTV (Lifetime Value) indicates a scalable business model.
CAC vs LTV
The relationship between CAC and Customer Lifetime Value (LTV) is critical:
LTV:CAC Ratio
- Less than 1:1: You're losing money on each customer
- 1:1 to 3:1: Break-even to marginal profitability
- 3:1 or higher: Healthy, sustainable growth
- Higher than 5:1: You might be under-investing in growth
Example
- CAC: $100
- Average Customer Value: $400
- LTV:CAC Ratio: 4:1 ✓ (Healthy)

- E-commerce: $10-$50
- Travel: $7-$15
- Real Estate: $200-$600

Common CAC Mistakes
1. Not Including All Costs
Many businesses underestimate CAC by excluding:
- Software and tools
- Team salaries and overhead
- Agency and contractor fees
- Content production costs
2. Wrong Time Period
Ensure you're matching costs and acquisitions from the same period. Some businesses have longer sales cycles where costs are incurred before conversions.
3. Ignoring Retention
High CAC can be acceptable if customer retention is strong. Always consider CAC alongside churn rate and LTV.
Frequently Asked Questions
What is CAC (Customer Acquisition Cost)?
CAC is the total cost your business spends to acquire a new customer. It includes all marketing and sales expenses divided by the number of new customers acquired in that period.
How do I calculate CAC?
CAC = (Total Marketing Cost + Total Sales Cost) ÷ Number of New Customers. For example, if you spend $10,000 on marketing and sales and acquire 100 customers, your CAC is $100.
What is a good CAC?
A good CAC depends on your Customer Lifetime Value (LTV). Generally, you want an LTV:CAC ratio of at least 3:1. This means the lifetime value of a customer should be at least 3 times your acquisition cost.
How can I reduce my CAC?
Focus on improving conversion rates, optimizing ad targeting, leveraging referrals and word-of-mouth, improving sales efficiency, and creating content that attracts organic traffic.
What costs should be included in CAC?
Include all marketing expenses (ads, content, tools, agency fees), sales team costs (salaries, commissions, software), and related overhead directly tied to customer acquisition.
