How to Calculate and Reduce Customer Acquisition Cost (CAC) for Your SaaS Business

As a SaaS business owner, you know that acquiring new customers is crucial to your success. But have you ever stopped to consider how much it costs to acquire those customers? This is where customer acquisition cost (CAC) comes in. Understanding CAC is essential for managing your budget and maximizing your revenue. In this blog post, we’ll cover what CAC is, how to calculate it, and strategies for reducing it.

Understanding CAC

CAC is the cost of acquiring a new customer. It includes all expenses related to sales and marketing, such as advertising, events, and salaries of sales and marketing personnel. To calculate CAC, divide your total sales and marketing expenses for a specific period by the number of customers you acquired during that same period.

For example, if you spent $100,000 on sales and marketing in the first quarter of the year and acquired 100 new customers, your CAC for that period would be $1,000.

Knowing your CAC is essential for budgeting and forecasting, as well as for measuring the success of your sales and marketing efforts. You can use it to determine the ROI of different marketing channels, such as social media, email, or search engine advertising.

Average CAC benchmarks for SaaS businesses vary depending on the industry, but they usually range from $400 to $2,000. However, it’s essential to note that CAC can be higher or lower depending on your business model, target audience, and competition.

Factors Affecting CAC

Several factors can impact your CAC, such as market competition, marketing and sales strategies, customer lifetime value (CLV), and seasonality.

For example, if your competitors are spending more on marketing and offering better deals, your CAC may be higher. If your sales and marketing strategies aren’t aligned, you may be targeting the wrong audience, resulting in a higher CAC.

Customer lifetime value (CLV) also plays a role in determining CAC. The higher the CLV, the more you can afford to spend on acquiring new customers. For instance, if your customers tend to purchase your software on a monthly or annual subscription, you can afford to spend more upfront to acquire them.

Lastly, seasonality and other external factors can impact your CAC. For example, if your business caters to students, your sales may increase during the back-to-school season, resulting in a higher CAC.

Strategies for Reducing CAC

To reduce CAC, you need to focus on improving lead generation and qualification, refining targeting and segmentation, enhancing the customer onboarding experience, and maximizing upselling and cross-selling opportunities.

1. Improve Lead Generation and Qualification

Lead generation is the process of attracting potential customers to your business. To reduce your CAC, you need to focus on generating high-quality leads that are more likely to convert into paying customers.

One way to generate high-quality leads is by creating targeted content. For example, if you offer accounting software for small businesses, you could create a blog post on “5 Accounting Tips for Small Business Owners.” This would attract potential customers who are interested in accounting and own a small business.

Lead qualification is the process of determining whether a lead is a good fit for your business. You want to make sure you’re spending time and resources on leads that are more likely to convert into paying customers.

To qualify leads, you can create a scoring system that assigns points to different actions, such as downloading a white paper, attending a webinar, or requesting a demo. Leads with higher scores are more likely to convert and should receive more attention from your sales team.

2. Refine Targeting and Segmentation

Targeting the right audience is essential for reducing your CAC. By focusing on the people who are most likely to become paying customers, you can maximize your marketing budget and improve your ROI.

To refine your targeting, you can use customer personas. These are fictional representations of your ideal customers, based on factors such as demographics, behavior, and interests. By creating customer personas, you can tailor your marketing and sales efforts to the specific needs and preferences of your target audience.

Segmentation is the process of dividing your audience into smaller groups based on shared characteristics. For example, you could segment your audience based on their location, company size, or industry. By segmenting your audience, you can create more targeted and personalized marketing messages that resonate with each group.

3. Enhance the Customer Onboarding Experience

The customer onboarding experience is critical for reducing churn and improving CLV. If your onboarding process is confusing, time-consuming, or unhelpful, your customers may become frustrated and cancel their subscription.

To enhance the customer onboarding experience, you can create a step-by-step guide that walks new customers through the setup and implementation process. You could also offer personalized training sessions or webinars to help them get started.

By providing a smooth and helpful onboarding experience, you can increase customer satisfaction and loyalty, leading to higher CLV and lower CAC.

4. Maximize Upselling and Cross-Selling Opportunities

Upselling and cross-selling are strategies for increasing revenue from existing customers. Upselling involves offering a higher-priced version of your product, while cross-selling involves offering complementary products or services.

By maximizing upselling and cross-selling opportunities, you can increase your CLV and reduce your CAC. For example, if you offer a basic and premium version of your software, you could encourage existing customers to upgrade to the premium version by highlighting its additional features and benefits.

You could also offer complementary products or services that align with your customers’ needs and preferences. For example, if you offer accounting software, you could also offer bookkeeping or tax preparation services.


In conclusion, customer acquisition cost (CAC) is a crucial metric for SaaS businesses. By understanding and reducing your CAC, you can maximize your revenue and grow your business more efficiently. To reduce your CAC, you need to focus on improving lead generation and qualification, refining targeting and segmentation, enhancing the customer onboarding experience, and maximizing upselling and cross-selling opportunities.

By implementing these strategies, you can acquire and retain high-quality customers that will provide long-term value to your business.
