Customer Acquisition Cost (CAC) is a key performance indicator (KPI) that measures the cost of acquiring a new customer. It is calculated by dividing the total cost of sales and marketing efforts by the number of new customers acquired during a specific period of time. CAC is often used by businesses to determine the efficiency of their sales and marketing efforts and to identify areas for improvement.
Understanding CAC
CAC is a measure of the efficiency of a company’s sales and marketing efforts in attracting and converting new customers. It takes into account all the costs associated with acquiring new customers, including advertising, marketing, sales, and customer support. CAC is typically expressed as a dollar amount per customer:
CAC = Total Cost of Sales and Marketing / Number of New Customers Acquired
For example, if a company spends $100,000 on sales and marketing efforts in a year and acquires 100 new customers, the CAC would be $1,000 per customer. This means that it cost the company an average of $1,000 to acquire each new customer.
CAC is an important metric because it helps businesses understand the cost of acquiring new customers and the return on investment (ROI) of their sales and marketing efforts. By tracking CAC over time, businesses can identify trends and make data-driven decisions to optimise their marketing and sales efforts and improve their ROI.
Factors that Affect CAC
There are several factors that can affect CAC, including:
- Market competition: CAC tends to be higher in markets with high competition, as businesses need to invest more in sales and marketing efforts to stand out and attract new customers.
- Marketing channels: Different marketing channels have different costs and effectiveness in acquiring new customers. For example, paid advertising through Google Ads may have a higher CAC than organic search or social media marketing.
- Marketing and sales efficiency: The efficiency of a company’s marketing and sales efforts can also impact CAC. Businesses that are able to effectively target and convert potential customers at a lower cost will have a lower CAC.
- Customer lifetime value (CLV): CLV is the estimated revenue a customer will generate for a business over the course of their relationship with the company. A higher CLV can justify a higher CAC, as the cost of acquiring a new customer can be offset by the revenue they generate over time.

Best Practices for Managing CAC
There are several best practices for managing CAC and optimising the efficiency of a company’s sales and marketing efforts:
- Track CAC over time: By tracking CAC over time, businesses can identify trends and make data-driven decisions to optimise their marketing and sales efforts and improve their ROI.
- Optimise marketing channels: By testing different marketing channels and measuring their CAC, businesses can determine the most effective and cost-efficient channels for acquiring new customers.
- Increase CLV: By focusing on improving customer retention and increasing the lifetime value of customers, businesses can justify a higher CAC, as the cost of acquiring a new customer can be offset by the revenue they generate over time.
- Improve marketing and sales efficiency: By optimising marketing and sales efforts, businesses can reduce the cost of acquiring new customers and improve their CAC. This may involve improving targeting and messaging, streamlining sales processes, and investing in training and development for sales and marketing teams.
- Reduce costs: Businesses can also reduce CAC by reducing the costs of sales and marketing efforts. This may involve cutting unnecessary expenses, negotiating better rates with vendors, or automating certain processes to reduce labour costs.
The Importance of CAC in PPC Advertising
In the context of pay-per-click (PPC) advertising, CAC is a particularly important metric to track, as it helps businesses understand the cost of acquiring new customers through paid advertising channels. By measuring the CAC of different PPC campaigns, businesses can determine the ROI of their advertising efforts and optimise their campaigns to improve their CAC and ROI.
One important consideration when tracking CAC in PPC advertising is the impact of invalid traffic on CAC. Invalid traffic, also known as ad fraud, refers to fake touchpoints that artificially inflate ad impressions and clicks, resulting in wasted ad spend and inflated CAC. To prevent invalid traffic and improve the accuracy of CAC calculations, it is important for businesses to use a tool like Lunio to detect and prevent ad fraud.
CAC and CLV: Balancing Short-Term and Long-Term Goals
CAC and CLV are closely related metrics, as the cost of acquiring a new customer is ultimately justified by the revenue that customer generates over time. As such, it is important for businesses to balance the short-term goal of reducing CAC with the long-term goal of increasing CLV.
In some cases, investing more in sales and marketing efforts to acquire new customers may be justified if it leads to higher CLV and long-term profitability. On the other hand, if CAC is too high relative to CLV, it may be necessary to focus on improving marketing and sales efficiency or reducing costs to improve CAC and increase profitability.
