How to Calculate Customer Acquisition Cost (CAC) and Why It Matters?

Calculate Customer Acquisition Cost (CAC)

Are You Wasting Money Acquiring New Customers?

As a business owner or marketer, acquiring new customers is crucial for growth and sustainability. However, the cost of acquiring those customers can quickly spiral out of control if you're not keeping a watchful eye on your customer acquisition cost (CAC). Calculating and monitoring your CAC is a vital practice that can save you from pouring money down the drain and help you make more informed decisions about your marketing and sales strategies.

But what exactly is customer acquisition cost, and why does it matter? Let's dive in and explore this essential metric.

What is Customer Acquisition Cost (CAC)?

Customer acquisition cost (CAC) is a metric that measures the total cost of convincing a customer to buy your product or service. It includes all the expenses associated with marketing, advertising, and sales efforts required to acquire a new customer.

The formula for calculating CAC is straightforward:

CAC = Total Cost of Acquisition / Number of New Customers Acquired

The total cost of acquisition encompasses all the expenses related to your marketing and sales activities during a specific period, such as:

  • Advertising costs (pay-per-click, social media ads, etc.)

  • Marketing campaign costs (email, content, events, etc.)

  • Sales team salaries and commissions

  • Tools and software used for marketing and sales

The number of new customers acquired refers to the total number of customers who made their first purchase from your business during the same period.

Why Does Customer Acquisition Cost Matter?

Understanding and optimizing your CAC is crucial for several reasons:

Profitability Assessment: Knowing your CAC allows you to determine whether your customer acquisition efforts are profitable or not. If your CAC is higher than the lifetime value of a customer (CLV), it means you're losing money on every new customer acquired. This unsustainable situation requires immediate attention and adjustments to your marketing and sales strategies.

Budget Allocation: By calculating your CAC, you can make informed decisions about where to allocate your marketing and sales budgets. If a particular channel or campaign has a high CAC, you may want to reallocate resources to more cost-effective channels or optimize the underperforming ones.

Competitive Advantage: Understanding your CAC in relation to your competitors can give you a significant advantage. If your CAC is lower than your competitors', you can potentially acquire customers at a lower cost, allowing you to reinvest those savings into product development, customer retention efforts, or other growth initiatives.

Scalability and Growth: As your business grows, keeping your CAC in check becomes even more important. A low CAC means you can acquire new customers more efficiently, enabling faster and more sustainable growth without draining your resources.

How to Calculate Customer Acquisition Cost?

Calculating your CAC involves gathering data from various sources, including your marketing, sales, and finance departments. Here's a step-by-step guide to help you get started:

Determine the Time Period: Choose a specific time period for your CAC calculation, such as a month, quarter, or year. This will ensure consistency in your data and allow you to track changes over time.

Identify Acquisition Costs: Gather all the expenses related to your marketing and sales efforts during the chosen time period. This may include advertising costs, marketing campaign expenses, sales team salaries and commissions, and any tools or software used for acquisition purposes.

Count New Customers Acquired: Determine the total number of new customers who made their first purchase from your business during the same time period. This data can typically be obtained from your customer relationship management (CRM) system or sales records.

Apply the CAC Formula: Once you have the total acquisition costs and the number of new customers acquired, simply divide the acquisition costs by the number of new customers to calculate your CAC for the chosen time period.

CAC = Total Acquisition Costs / Number of New Customers Acquired

For example, if your total acquisition costs for the quarter were $100,000 and you acquired 500 new customers, your CAC for that quarter would be:

CAC = $100,000 / 500 = $200

Monitor and Optimize: Calculating your CAC is not a one-time exercise. It's essential to monitor your CAC regularly (monthly, quarterly, or annually) to identify trends and make necessary adjustments to your marketing and sales strategies.

Strategies to Reduce Customer Acquisition Cost

Once you have a clear understanding of your CAC, you can explore strategies to reduce it and improve the efficiency of your customer acquisition efforts. Here are some effective tactics to consider:

Optimize Your Marketing Channels: Evaluate the performance of your marketing channels and double down on the ones that yield the lowest CAC. Continuously test and optimize underperforming channels or consider reallocating resources to more cost-effective alternatives.

Improve Conversion Rates: By improving the conversion rates of your marketing and sales funnels, you can acquire more customers without increasing your acquisition costs. Focus on enhancing your website's user experience, refining your messaging, and streamlining the purchase process.

Leverage Referral Programs: Implementing a referral program can be a cost-effective way to acquire new customers. Incentivize your existing customers to refer their friends and family, effectively turning them into brand advocates and reducing your CAC.

Enhance Customer Retention: While CAC focuses on acquiring new customers, retaining existing ones is equally important. Investing in customer retention strategies, such as loyalty programs, excellent customer service, and upselling/cross-selling efforts, can lower your overall acquisition costs in the long run.

Automate and Streamline Processes: Automating and streamlining your marketing and sales processes can help reduce operational costs and increase efficiency. Consider implementing tools and technologies that can automate tasks, improve lead nurturing, and optimize your team's productivity.


Mastering the art of calculating and optimizing your customer acquisition cost is a game-changer for any business. By understanding this crucial metric, you can make data-driven decisions, allocate your resources effectively, and ultimately, acquire new customers more profitably.
