Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC)

Customer Acquisition Cost (CAC) is a fundamental metric in the world of marketing that measures the expenses incurred by a business to acquire a new customer. This essential figure encompasses various costs associated with marketing and sales efforts, such as advertising, promotions, salaries of sales teams, and any other expenditures aimed at attracting and converting prospects into paying customers. CAC provides businesses with valuable insights into the efficiency of their marketing strategies and helps them determine the sustainability and profitability of their customer acquisition efforts.

CAC is calculated by dividing the total cost incurred to acquire new customers within a specific period by the number of customers acquired during that same period. This formula allows businesses to assess the cost-effectiveness of their marketing campaigns and make informed decisions about resource allocation and strategy adjustments. The ultimate goal of optimizing CAC is to ensure that the cost of acquiring customers does not exceed the lifetime value (LTV) of those customers, guaranteeing a positive return on investment (ROI).

In essence, CAC is the financial yardstick that helps businesses evaluate how efficiently they are growing their customer base and whether they need to refine their marketing approaches for better results.

TL;DR What is Customer Acquisition Cost (CAC)?

Customer Acquisition Cost (CAC) is the total cost a business incurs to acquire new customers, including expenses related to marketing and sales efforts. It is a crucial metric used to assess the efficiency of customer acquisition strategies.


Customer Acquisition Cost plays a pivotal role in shaping a company’s marketing strategies and campaigns. Here’s why it’s so important:

  1. Resource Allocation: CAC assists businesses in allocating their marketing budgets effectively. By knowing how much it costs to acquire a customer, they can distribute resources where they are most likely to yield profitable results.
  2. Profitability Assessment: Calculating CAC in conjunction with Customer Lifetime Value (CLV) helps businesses determine whether their customer acquisition efforts are profitable in the long run. If CAC exceeds CLV, it indicates a need for adjustments.
  3. Performance Benchmark: CAC serves as a benchmark for evaluating the performance of different marketing channels and campaigns. Companies can identify which channels are delivering the most cost-effective results and allocate resources accordingly.
  4. Scalability: Understanding CAC enables businesses to assess whether they can scale their operations profitably. Lowering CAC while maintaining quality ensures sustainable growth.

  • Subscription Service: A subscription-based streaming platform spends $50,000 on marketing campaigns in a quarter and gains 2,000 new subscribers. The CAC for this period is $50,000 / 2,000 = $25 per subscriber.
  • SaaS Company: A Software as a Service (SaaS) company spends $100,000 on sales and marketing in a year and acquires 500 new clients. The CAC is $100,000 / 500 = $200 per client.
