Customer Acquisition Cost (CAC)

Customer Acquisition Cost, or CAC, measures how much an organization spends to acquire new customers. CAC – an important business metric – is the total cost of sales and marketing efforts, as well as property or equipment, needed to convince a customer to buy a product or service.

What is Customer Acquisition Cost (CAC)?

Customer acquisition cost (CAC) is the cost related to acquiring a new customer. In other words, CAC refers to the resources and costs incurred to acquire an additional customer. Customer acquisition cost is a key business metric that is commonly used alongside the customer lifetime value (LTV) metric to measure value generated by a new customer.

Customer acquisition vs. customer satisfaction

Customer acquisition and customer satisfaction may seem different, but they’re actually highly interconnected.

Customer acquisition is the process of bringing new customers into your business, and it’s required for business expansion and generating revenue. However, focusing solely on customer acquisition without adequately considering customer satisfaction can lead to a high churn rate, which in turn increases your cost of customer acquisition (CAC).

On the other hand, customer satisfaction speaks to how happy your existing customers are with your product or service. A high level of customer satisfaction can lead to increased customer retention, repeat purchases, and referrals, all of which can lower your CAC.

In essence, driving customer acquisition is crucial, but maintaining customer satisfaction is equally important — if not more important —  for sustainable business growth.

Where:

  • Sales and marketing expenses are the advertising and marketing spend, commissions and bonuses paid, salaries of marketers and sales managers, and overhead costs related to sales and marketing over the measurement period.
  • Number of new customers is the total number of acquired customers over the measurement period.

Factors affecting customer acquisition cost

CAC is influenced by various factors, and understanding these factors can empower you to adjust your marketing and sales strategies more effectively. Let’s take a closer look at some elements that can impact your customer acquisition cost:

  1. Marketing channels: Different marketing channels come with different costs. Paid advertising, content marketing, social media marketing, and organic search will all have varying expense levels associated with them. The effectiveness of your chosen channels and the costs involved can greatly affect your overall CAC.

  2. Target audience: The demographics and preferences of your target audience play a significant role in determining your CAC. Certain audience segments may be more expensive to market to due to high competition, whereas others might be less expensive due to lower competition or a niche audience.

  3. Industry: Your sector can also influence your CAC. Companies in highly competitive industries might face stiffer competition, making it more challenging and expensive to acquire new customers.

  4. Competition: Higher competition can lead to businesses vying for the same customer base, which can result in escalating advertising expenses and overall acquisition costs.

  5. Product quality and offerings: A well-crafted, high-quality product or service, paired with competitive pricing, can help reduce CAC. Generally, a good product will require less convincing, reducing the effort required to get new customers on board.

  6. Geographic location: The geographic regions targeted by your marketing also contribute to CAC. Advertising rates and marketing costs will vary depending on the region, country, and sometimes even city.

Customer acquisition cost by industry

Just as businesses vary by nature, size, and operation, CAC also varies across industries. It’s important to consider these variations when setting your expectations and crafting your strategies.

Here’s an overview of how CAC can change based on different industries:

Tech/digital services

Tech and digital service companies typically have high CAC due to the technology and skill investments they require. However, their high potential customer lifetime value (CLV) often offsets this cost, making this high CAC more manageable.

Ecommerce

With competition high and margins often low, ecommerce businesses often have a challenging CAC scenario. These businesses must pay close attention to their CAC and constantly innovate to maintain their balance of value.

Healthcare

In the healthcare industry, the cost to acquire new customers can often be high due to a heavy emphasis on trust and quality of care, which can lead to higher marketing and sales costs.

Education

Educational institutions often have a lower CAC since they mostly rely on referrals, reputation, and direct inquiries. However, ed-tech companies may face higher CAC due to the competitive market and cost of technology.

Knowing where your business stands in relation to the industry standard can offer helpful perspective and ground your CAC goals in reality. Remember, the key is not necessarily to lower your CAC but to optimize it in harmony with your customer lifetime value (CLV). So while studying your industry’s norms, keep your focus on the bigger picture.

How to improve CAC

  1. Aim for high-quality leads: Not all leads are created equal. Some will engage more, convert into paying customers, and likely stick around longer. High-quality leads not only help lower the CAC but also increase CLV.

  2. Optimize your marketing channels: Some channels might work better than others for your business. When you find a marketing channel that offers a high return on investment, focus more of your budget and effort there.

  3. Improve conversion rates: Optimizing your website for conversions can reduce your CAC. Test different elements of your website, like headings, calls to action, site speed, and navigation to reduce friction in the user experience.

  4. Customer retention strategies: It’s often cheaper to retain existing customers than to research, market to, and attract new ones. Look for ways to increase customer loyalty through excellent service and adding value wherever possible.

  5. Referral programs: Happy customers are your best advocates. Implementing a referral program can not only attract new customers at a lower cost but also help in increasing engagement and loyalty of your existing customers.

  6. Superior customer support: Customer support plays a crucial role in retaining existing customers and winning over new ones.
