Customer acquisition cost

Key takeaways

Measures the cost efficiency of gaining new customers

Crucial metric for assessing marketing and sales effectiveness

Includes both direct and indirect costs of acquisition

Often compared with customer lifetime value (CLV) for profitability analysis

Varies significantly across industries and business models

Customer Acquisition Cost = Total acquisition costs/ Number of new customers acquired

Acquisition costs typically include:

Advertising expenses
Marketing team salaries
Sales team compensation
Software and tools used in marketing and sales
Creative costs for content and ad production

Understanding CAC is essential for:

Evaluating the effectiveness of marketing channels
Determining appropriate customer pricing
Assessing overall business profitability
Making informed decisions about marketing budget allocation
Comparing performance against industry benchmarks

A low CAC relative to the customer's lifetime value indicates efficient acquisition strategies and potential for profitability. Conversely, a high CAC may signal the need for more cost-effective marketing approaches or a reevaluation of the target market.

Real-world examples

Case study: Airbnb's two sided market place

Airbnb faces the unique challenge of acquiring both hosts and guests to fuel its platform. In 2022, the company allocated $1.19 billion to sales and marketing. With 6.6 million active listings by the end of 2022, this spend highlights the cost of acquiring hosts, which plays a significant role in Airbnb's growth. However, the customer acquisition cost (CAC) for Airbnb is multifaceted, given its two-sided marketplace, where both guests and hosts must be recruited and retained for success.

Dual acquisition effort: Airbnb must focus on acquiring both hosts and guests, each requiring different strategies. While guest acquisition relies on traditional marketing, attracting hosts demands building trust and offering incentives.

High complexity in CAC: Due to the two-sided marketplace, calculating CAC is more complex for Airbnb. The cost of recruiting hosts (who provide listings) is just as critical as acquiring guests.

Marketing spend allocation: The $1.19 billion spent on marketing in 2022 emphasises Airbnb's strategic focus on ensuring both sides of its marketplace are equally supported.

Growth leverage: Airbnb’s success lies in its ability to balance the acquisition of both hosts and guests, ensuring a consistent flow of listings and bookings across the platform.

2) How does CAC relate to customer lifetime value (CLV)?

Ideally, CLV should be significantly higher than CAC to ensure profitability. The ratio of CLV to CAC is a key indicator of business health.
