Understanding the difference between customer acquisition cost vs customer lifetime value, that is CAC vs CLV is essential for businesses looking to thrive in a competitive market. Calculating CAC and CLV helps companies evaluate the effectiveness of their marketing and sales strategies, as well as make informed decisions regarding customer acquisition and retention.
Understanding customer acquisition cost (CAC)
Customer acquisition cost (CAC) refers to the amount of money a business spends to acquire a new customer. It is an essential metric for businesses to track as it helps them determine the effectiveness of their marketing and sales strategies. CAC takes into account all the costs incurred in attracting and converting a lead into a paying customer. These costs may include advertising expenses, marketing campaigns, employee salaries, and any other resources utilized in the customer acquisition process.
How to calculate CAC
Calculating customer acquisition cost is relatively straightforward. To determine the CAC, divide the total costs associated with acquiring customers by the number of customers acquired during a specific period.
CAC = Sales & Marketing Cost / Total Customers Acquired
For example, if a company spends $10,000 on marketing and sales efforts in a month and acquires 100 customers, the CAC would be $100.
Understanding Customer lifetime value (CLV)
Customer lifetime value (CLV) is a metric that estimates the total revenue a business can expect to generate from a customer throughout their entire relationship. It takes into account not only the initial purchase but also the potential future purchases and the duration of the customer’s engagement with the business. CLV is a crucial metric as it helps companies understand the long-term value of their customer base and guides decision-making regarding customer retention and acquisition strategies.
How to calculate customer lifetime value
Calculating customer lifetime value involves estimating the average value of a customer’s purchase and multiplying it by the number of purchases they are likely to make in a given period. The next step is to multiply this value by the average lifespan of a customer.
CLV = Customer Value x No. of purchases x Avg Customer Lifespan
For example, if a customer typically spends $100 per purchase and makes an average of 5 purchases in a year, with an expected customer lifespan of 3 years, the CLV would be $1,500.
The relationship between CAC and CLV
The relationship between CAC and CLV is crucial in determining the financial health of a business.
Ideally, the CLV should be significantly higher than the CAC. This indicates that the revenue generated from a customer over their lifetime exceeds the cost of acquiring them. A positive CLV:CAC ratio demonstrates that a business is making a profit from its customer base and can afford to invest in customer acquisition.
On the other hand, if the CAC is higher than the CLV, it suggests that the business is spending more to acquire customers than it can potentially earn from them, leading to unsustainable growth.
Evaluating CAC and CLV: Which is more important?
Determining whether CAC or CLV is more important depends on the specific goals and circumstances of a business. In general, both metrics are crucial for understanding the financial viability of a customer acquisition strategy. However, if a business is focused on short-term growth and rapid customer acquisition, CAC may hold more significance. On the other hand, for businesses with a long-term perspective and a focus on customer retention and loyalty, CLV becomes more critical. Striking a balance between the two metrics is essential for sustainable growth and profitability.
