What is Customer Acquisition Cost (CAC)?
Customer acquisition cost (CAC) is a metric that measures the average cost of acquiring a new customer. It's essentially the total spend on sales and marketing efforts divided by the number of new customers acquired during a specific period.
How to calculate Customer Acquisition Cost (CAC)
The basic formula for calculating CAC is:
CAC = Total Sales & Marketing Costs / Number of New Customers Acquired
This includes costs such as:
Marketing expenses: Advertising, content marketing, social media marketing, search engine optimization (SEO), pay-per-click (PPC) advertising, etc.
Sales expenses: Salaries and commissions for salespeople, sales tools and technology, training, etc.
Other costs: Referral programs, public relations, events, etc.
Let's look at an example to illustrate Customer Acquisition Cost (CAC). Imagine an SMB sells workout equipment online. During a recent sales campaign, they invested the following:
Marketing expenses:
- $10,000 on social media ads
- $4,000 on search engine ads
- $2,000 on influencer partnerships
Sales expenses:
- $6,000 on salaries for sales representatives
- $2,000 on sales software
Through this campaign, they acquired 300 new customers. To calculate their CAC, they would use the formula:
CAC = Total Sales and Marketing Costs / Total New Customers Acquired
CAC = ($10,000 + $4,000 + $2,000 + $6,000 + $2,000) / 300
CAC = $24,000 / 300
CAC = $80
Therefore, their customer acquisition cost for this campaign was $80 per customer.
This means they spent an average of $80 to acquire each new customer. Whether this cost is good depends on factors like industry benchmarks, customer lifetime value, profit margin, campaign specifics, and growth metrics. Achieving a low customer acquisition cost (CAC) isn't necessarily the primary goal. Instead, our focus should be on obtaining high-quality customers to ensure sustainable growth.
Why is Customer Acquisition Cost (CAC) Important?
CAC is a crucial metric for businesses of all sizes because it helps them understand:
The efficiency of their customer acquisition efforts: A low CAC indicates that you're effectively bringing in new customers at a reasonable cost. Conversely, a high CAC suggests that your acquisition strategies need refinement. High CAC relative to the customer's lifetime value can lead to unsustainable business models.
The profitability of customer relationships: By comparing CAC to customer lifetime value (LTV), you can gauge whether your customers are generating enough revenue to cover the cost of acquiring them. Your LTV should be several times higher than your CAC.
- The effectiveness of different marketing channels: Tracking CAC by channel can help you identify which marketing efforts bring in the most customers at the lowest cost.

Factors affecting Customer Acquisition Cost (CAC)
Several factors can affect a company's CAC, including:
Industry: Different industries have different average CACs. For example, acquiring customers in the B2B space is typically more expensive than in the B2C space.
Business model: Subscription-based businesses often have lower CACs than businesses that sell one-time purchases.
Customer acquisition channels: Some channels, such as PPC advertising, can be more expensive than others, such as organic SEO.
- Target audience: Your target audience's demographics and online behavior can impact the cost of reaching them.
