In this series of articles we are looking closer into common Customer Acquisition Cost (CAC) metrics for businesses, to grasp a better understanding of CAC metrics and how to influence them to reduce CAC. Last article dived into the CAC by Channel metric, which provides insights into the effectiveness of each channel in acquiring customers. Now the time has come to look closer at the CAC Payback Period.
The CAC Payback Period represents the time it takes for a SaaS business to recoup the investment made in acquiring a new customer through the revenue generated from that customer. It is calculated by dividing the CAC by the average revenue per customer per unit of time (e.g., month or year). This metric provides insights into the efficiency of customer acquisition efforts and the company's ability to achieve positive cash flow from new customers in a timely manner.
So what is a good CAC Payback Period you may wonder. Well, that depends. For businesses selling to SMEs you would expect a lower CAC Payback Period than for those selling to Enterprises. Essentially, a CAC Payback Period of less than 12 months is great as this signals you have a scalable operation and probably have found your sales process fit. In this case, you should invest more in whatever you are doing (marketing, new sales reps, etc.) as you will get your investment back in less than a year . Be aware, however, that high performing individuals can influence the metric and that new sales reps usually requires some ramp-up time before hitting their quota. In other words, by investing more in already proven processes may slow them down for a while as your organization get settled.
Normally, for SMEs you would be confident if your CAC Payback Period is lower than 15-18 months, and less than 24-27 months for Enterprises. If your metric is higher than this, you should not freak out but rather look closer into how your sales and marketing process is set-up, and whether it is possible to increase your prices. Generally, if your target audience are SMEs and your CAC Payback Period is 18+ months your sales process is inefficient and you should consider to find more scalable ways to distribute your product.
For an Enterprise-focused company, it might be hard to see how you can improve this metric as the complexity these in sales processes requires more attention from your sales team, however, there are different go-to-market strategies that can be considered such as "land and expand" where you sell a smaller part of your solution with less sales effort and then focus on upsell and expansion strategies.
Continuously reducing your CAC Payback Period will help you achieve ARR growth increasing your Monthly Recurring Revenue (MRR) and help you unlock profitability for sustainable growth. Moreover, having healthy CAC levels will improve your CLV:CAC and influence Sales Efficiency Ratio to help you unleash your potential.
Tracking CAC Payback Period offers several key benefits for SaaS businesses:
Let's consider a hypothetical example to illustrate the calculation of CAC Payback Period:
CAC Payback Period = CAC / (Average Revenue per Customer per Month * Number of Months)
In this case:
This analysis reveals that it would take Company XYZ 100 months, or approximately 8.3 years, to recoup the customer acquisition costs through the revenue generated from those customers.
By tracking and optimizing the CAC Payback Period, SaaS businesses can improve financial health, increase cash flow efficiency, and achieve sustainable growth. Implementing strategies to shorten the payback period not only enhances profitability but also strengthens the company's competitive position in the market. Continuous monitoring, analysis, and optimization are key to maximizing the effectiveness of customer acquisition efforts and driving long-term success in the SaaS industry.
