SaaS Terms Explained: Customer Acquisition Cost (CAC)

As a software as a service (SaaS) provider, measuring various metrics is vital to the success of your business. One such metric is customer acquisition cost (CAC), which is the cost associated with acquiring a new customer. In this article, we'll walk you through everything you need to know about CAC, including how to calculate it, factors that influence it, and how to reduce it.

Understanding Customer Acquisition Cost (CAC)

Customer acquisition cost refers to the amount of money you need to spend to acquire a new customer. It's a critical metric for SaaS businesses since it directly impacts profitability. Whenever an SaaS company spends money on marketing, sales, promotions, or advertising, they incur a cost. CAC helps in measuring the efficiency of these investments. By calculating how much money you're spending to acquire customers, you can determine how much revenue each customer must contribute to ensure that your business remains profitable.

What is Customer Acquisition Cost (CAC)?

Customer acquisition cost is a metric used to measure how expensive it is for a business to acquire a new customer. It's calculated by dividing the total cost spent on marketing and sales by the number of new customers gained in a given period. Essentially, CAC helps you identify the cost per customer acquisition and helps you allocate your resources accordingly.

For example, if your SaaS company spent $10,000 on marketing and sales in a month and acquired 100 new customers during that period, your CAC would be $100.

Importance of CAC in SaaS business models

In SaaS business models, customer acquisition cost is a critical metric since the business model itself is heavily focused on customer lifetime value (CLTV). CLTV refers to the total revenue a customer generates over the course of their relationship with your business. If the cost of acquiring a customer is too high, it makes it challenging to achieve the desired CLTV. By keeping the CAC low, you can keep CLTV high, and in turn, generate healthy revenue streams for your business.

For example, if your SaaS company has a CLTV of $1,000 and a CAC of $100, it means that you can expect to generate $900 in revenue from each customer over their lifetime. If your CAC were to increase to $200, it would cut your profit in half.

How to Calculate CAC

Calculating customer acquisition cost isn't complicated – you need to divide the total amount you spent on acquiring customers by the total number of new customers acquired. The formula looks like this:

  1. Gather all marketing and sales costs for the period you're analyzing.

  2. Calculate the total number of new customers acquired in that period.

  3. Divide the total marketing and sales costs by the total number of new customers.

  4. The result is your CAC for that period.

It's essential to remember that customer acquisition cost should be a dynamic number that you should track regularly. If you notice your CAC begins to deviate from your expectations, it's essential to take a closer look and adjust accordingly. For example, you may need to adjust your marketing strategy to target a different audience or optimize your sales process to reduce costs.

Ultimately, understanding and managing your CAC is critical to the success of your SaaS business. By keeping your acquisition costs low and maximizing customer lifetime value, you can build a sustainable and profitable business that delivers value to both your customers and your stakeholders.

Factors Influencing Customer Acquisition Cost

Customer Acquisition Cost (CAC) is a critical metric for businesses, especially those operating on the Software-as-a-Service (SaaS) model. CAC refers to the amount of money a business spends on acquiring a new customer. Several factors influence CAC in SaaS business models. Understanding these factors will help you optimize your resources better and reduce overall costs. Here are the four significant factors that influence CAC:

Marketing and Advertising Expenses

Marketing and advertising are essential components of any business strategy. However, the amount of money spent on advertising and marketing directly impacts CAC. Higher marketing and advertising expenses lead to higher CAC, while lower expenses lead to lower CAC. Therefore, it's crucial to monitor marketing expenses and determine their impact on acquiring new customers to optimize CAC.

Businesses can use various marketing channels, including social media, email marketing, search engine optimization (SEO), and pay-per-click (PPC) advertising, to reach their target audience. However, it's essential to identify the most effective channels to avoid wasting resources and increasing CAC. Conducting A/B testing and analyzing metrics such as click-through rates (CTR) and conversion rates can help optimize marketing and advertising expenses.

Sales Team Efforts

The sales team's performance and productivity can significantly influence customer acquisition costs. Metrics like conversion rate and sales cycle duration determine how many leads turn into actual customers and how long it takes to happen. Therefore, ensuring that the sales team is highly motivated and productive is vital to maintaining a low CAC.

Businesses can optimize sales team efforts by providing adequate training, setting realistic targets, and incentivizing performance. Additionally, using customer relationship management (CRM) software to track leads and analyze sales data can help identify areas that need improvement and optimize sales team efforts.

Product Pricing and Packaging

Product pricing and packaging can positively or negatively impact CAC, depending on how they align with your target audience. Higher-priced products or complex package offerings might deter potential customers, leading to higher CAC. Therefore, tailoring pricing and packaging to your target audience can help optimize CAC.

Businesses can use various pricing strategies, such as value-based pricing, cost-plus pricing, and penetration pricing, to optimize CAC. Additionally, offering different package options and customizing packages to meet customers' specific needs can increase the perceived value of the product and reduce CAC.

Target Audience and Market Competition

The target audience and the competition are critical factors in determining CAC. Niche or highly competitive markets will have higher CAC than less competitive markets, given the significant investments required in terms of marketing and sales. Therefore, understanding how target audiences and competition impact CAC can help businesses make informed decisions on marketing and sales strategies.

Businesses can use various market research techniques, such as surveys and focus groups, to identify their target audience's needs and preferences. Additionally, analyzing competitors' marketing and sales strategies can help identify gaps and opportunities to optimize CAC.

Optimizing CAC is critical for businesses, especially those operating on the SaaS model. By understanding the factors that influence CAC, businesses can make informed decisions on resource allocation and improve their overall profitability.

Reducing Customer Acquisition Cost

Reducing customer acquisition costs will help businesses maximize their revenue potential by ensuring that the costs incurred to acquire customers remain minimal. Here are a few strategies to reduce CAC:

Optimizing Marketing Strategies

Optimizing marketing strategies can help reduce CAC. By understanding which marketing channels are most effective, businesses can channel their resources towards them and optimize their CAC.

Leveraging Organic Channels

Leveraging organic channels like social media or referral programs can be a cost-effective way to acquire customers. Encouraging existing customers to refer new customers can have a significant impact on CAC, reducing it substantially.

Improving Sales Team Efficiency

Improving the sales team's productivity can significantly reduce CAC. Ensuring that sales teams respond quickly and efficiently to leads can shorten the sales cycle duration and increase conversion rates.

Refining Product Offerings and Pricing

Refining product offerings and pricing to align with the target audience can reduce CAC. By providing customers with solutions tailored to their needs, businesses can reduce sales cycles and lower marketing and advertising expenses.

Analyzing CAC in Relation to Other SaaS Metrics

Customer acquisition cost must be viewed in relation to other SaaS metrics to gain a more comprehensive understanding of business health. Here are a few metrics you should consider when analyzing CAC:

Customer Lifetime Value (CLTV)

Customer lifetime value refers to the total revenue generated by a customer over their lifetime. CLTV should be higher than CAC to ensure profitability and a successful business model.

Churn Rate

Churn rate is the number of customers who leave over a given period. High churn rates negatively impact CLTV and increase CAC since new customers must replace the lost revenue.

Average Revenue Per User (ARPU)

Average revenue per user is the average revenue generated by each customer. ARPU can help in determining whether the product pricing aligns with the target audience and can have a significant impact on CAC.

CAC Payback Period

CAC payback period is the amount of time it takes for an SaaS company to recoup the cost of customer acquisition. A long payback period might not be sustainable or profitable, leading to optimization of the marketing and sales strategies.


Customer acquisition cost is a critical metric for SaaS businesses. It impacts profitability and can be optimized by tracking and analyzing the various factors that influence it. By reducing CAC and monitoring other SaaS metrics like CLTV, ARPU, and churn rate, businesses can create a sustainable and profitable business model.
