How to Calculate CAC: Customer Acquisition Cost Formula
Customer acquisition costs measure the total cost of your sales and marketing efforts to earn new customers over a specified period of time. The equation to calculate CAC is to divide all the costs spent on acquiring new customers (both sales and marketing expenses) by the number of customers acquired in the same time period.
CAC Calculation Example
A small online clothing store is calculating CAC for the month of October. During October, this company spent $5,000 on marketing and sales. This includes everything from social media ad campaigns to email marketing software to the time the commerce-driving team spent crafting catchy social media captions.
In that same month, 200 new customers were acquired. The CAC formula can be used to calculate CAC for the month of October for this small online clothing store. Divide your total marketing spend by the number of new customers. So, it looks like this: $5,000 ÷ 200 = $25.
CAC for the month of October is $25. That means, on average, the small online clothing retailer spent $25 to acquire each new customer. Understanding this figure is a game-changer. It helps businesses evaluate whether marketing and sales efforts are cost-effective and where there might be room for improvement.
What is the LTV: CAC Ratio?
The LTV:CAC ratio is a key performance indicator that helps businesses understand their return on investment in customer acquisition. The acronym stands for “lifetime value to customer acquisition cost” ratio. This ratio compares the average cost of acquiring a customer (CAC) to the average lifetime value of a customer (LTV).
A healthy LTV:CAC ratio is considered to be 3:1 or better. This means that the value you get from a customer over their lifetime should be three times more than what you spent to acquire them. If the ratio is 1:1, it implies you’re losing money the more you sell because you’re not earning back your investment in customer acquisition. On the other hand, a ratio of 4:1 or higher indicates an exceptional business model where the return on customer acquisition cost is high.
It’s important to understand that while a higher LTV:CAC ratio is generally better, an extremely high ratio could indicate underinvestment in marketing and growth opportunities. It’s all about finding the right balance. This ratio not only helps in understanding your customers’ overall spending with your business based on how much you spend to earn them but also serves as a primary indicator of your brand’s profitability, growth potential, and the overall health of your business.
The LTV:CAC ratio offers a clear picture of customer profitability against acquisition costs. By understanding this metric, businesses can make informed decisions about their marketing and sales strategies, ensuring they’re investing their resources where they’ll see the most return.
How to Calculate LTV to CAC Ratio
Understanding how to calculate the LTV to CAC ratio is crucial for any ecommerce company.
The formula for calculating the LTV:CAC ratio is straightforward: you simply divide the customer lifetime value (LTV) of a customer by the customer acquisition cost (CAC). The LTV represents the total revenue you can expect from a customer over their lifetime, while the CAC is the total cost of acquiring that customer.
Let’s break down how to calculate each component:
- Calculate LTV: To calculate the LTV, you’ll need to determine the average purchase value, average purchase frequency, customer lifespan, and profit margin. Multiply the average purchase value by the average purchase frequency to get the customer value per year. Then, multiply this by the average customer lifespan to get the total customer value. Finally, multiply the total customer value by the profit margin to get the LTV.
- Calculate CAC: To calculate the CAC, add up all the costs spent on acquiring more customers (marketing and sales expenses), then divide by the number of customers acquired in the period the money was spent.
Once you have these two figures, simply divide the LTV by the CAC to get your LTV:CAC ratio.
As an example, if your LTV is $3,000 and your CAC is $1,000, your LTV:CAC ratio would be 3:1. This means that you’re earning $3 for every $1 spent on acquiring a new customer, which is generally considered a healthy ratio.
Remember, the higher the ratio, the higher the return on your investment in customer acquisition. However, an extremely high ratio could indicate underinvestment in growth opportunities. It’s about finding a balance that works best for your unique business situation.

What is Customer Acquisition Cost?
Customer acquisition cost, commonly referred to as CAC, represents the total cost of convincing a potential customer to buy your company’s product or service. It includes all marketing and sales costs involved in attracting that new customer.
Knowing how to calculate CAC via the CAC formula gives you a powerful insight into how much you’re investing to gain each new customer. This retail math knowledge enables you to make informed decisions about where to allocate important resources and how to steer your growth strategy. A lower CAC means you’re acquiring customers more efficiently — a clear win for any ecommerce company.
Why Customer Lifetime Value (LTV) is Important
Few business metrics are as crucial to your long-term success as customer lifetime value (LTV). This powerful metric offers a glimpse into the future, projecting the total revenue you can expect from a customer over their lifetime. Here’s why it is so important:
- Understanding Profitability: LTV is fundamental in understanding customer profitability. It tells you how much net profit each customer is expected to bring to your business over the course of their relationship with you. A high LTV indicates that customers are likely to continue doing business with you, which translates to more revenue and profit for your company.
- Smarter Marketing Decisions: It also helps in making smarter marketing decisions. By knowing the lifetime value of a customer, you can determine how much you should be spending to acquire new customers (customer acquisition cost) and retain existing ones. If your LTV is high, it might be worth investing more in customer acquisition and retention strategies or in reengagement campaigns.
- Targeting the Right Customers: LTV helps in identifying and targeting the right customers. Not all customers are equal. Some will buy more, refer more, and stay loyal longer. Understanding who these customers are allows you to target your marketing efforts more effectively, leading to a higher return on investment.
- Forecasting Revenue and Growth: LTV is also essential for forecasting future revenue and growth. With this metric, you can predict how changes in customer behavior or market conditions might affect your company’s financial future. It’s like having a crystal ball that can guide your strategic planning.
In essence, customer lifetime value is more than just a number. It’s a strategic tool that can help you navigate the complex landscape of business growth. It empowers you to make informed decisions, optimize your marketing efforts, and ultimately, drive sustainable growth.
Improving CAC and LTV
Both CAC and LTV are crucial for measuring the effectiveness of your marketing efforts, and improving them can significantly boost your profitability.
To reduce CAC, think about refining your marketing strategies. Use targeted campaigns to reach audiences who are more likely to convert, thereby getting more bang for your buck. Optimizing your website for SEO also helps attract organic traffic, reducing reliance on paid advertising. A robust customer referral program can lead to new customers at a lower cost.
LTV is the total revenue you expect from a customer over their lifetime. Boosting this involves enhancing customer retention and increasing the frequency or value of purchases. You can do this by providing exceptional customer service, creating loyalty programs, or offering upsells and cross-sells. Personalized email marketing campaigns can also encourage repeat purchases, improving your LTV.
The LTV:CAC ratio is also essential to consider. If you’re spending more to acquire a customer than they’re worth, you’re running at a loss. Conversely, if your LTV is significantly higher than your CAC, you might be missing opportunities to invest in growth.
So, take a holistic approach. Look at ways to simultaneously decrease your CAC while increasing your LTV for the best results. By doing so, you’re not only making your marketing efforts more efficient but also maximizing the value of each customer relationship.
Focusing on improving your CAC and LTV can pave the way for sustainable growth and profitability. It’s all about smart spending, targeted marketing, and building long-lasting, valuable relationships with your customers.
