Customer lifetime value (CLV) refers to calculating the contribution of each customer to your business for the lifetime. You indeed have to pay something to get another thing. So, a customer's lifetime value is the return of your marketing efforts.
Customer lifetime value helps you to improve your services to get maximum ROI. So, let's study several methods to calculate CLV.
Calculate by CLV Formula
The CLV formula is similar to calculating return on investment (ROI). Subtract the total cost you spend on the customer from the total revenue you got from the customer for the lifetime.
Formula: CLV = lifetime revenue - lifetime cost
For example:
You spent 100$ to gain, retain and serve a customer. However, the revenue you generate from that customer is 160$.
Then according to the CLV formula,
160$ - 100$ = 60$
60$ is the customer's lifetime value.
Well, each customer is different. Some customers make one-time purchases, and some are loyal ones. So, we can only determine the lifetime value of each customer through this formula.
Calculate by Customer Revenue Distribution
Customer revenue distribution is the more reliable method of CLV calculation. Initially, we group the customers based on their purchases.
Let's assume the groups to make a better understanding:
Group 1: Customer who purchase for 35$
Group 2: Customers who purchase for 70$
Group 3: Customers who purchase for 100$
We must determine how many customers fall into each group to pursue customer revenue distribution.
For instance:
Group Number
Number of customers
1
86
2
120
3
159
Now put the values in the formula to calculate CLV.
Formula: CLV= (group 1 no. of customers x group 1 purchases) + (group 2 no. of customers x group 2 purchases) + (group 3 no. of customers x group 3 purchases) and so on…
Calculation:
CLV= (86 x 35) + (120 x 70) + (156 x 100) = 27,010
Now divide the total value by the total number of customers to get CLV
CLV = 27,010 / 362 = 74.6$
We take into account the one-time customers, the occasional customers, and the regular customers in the revenue distribution method. So, the CLV calculated from this method is more reliable and accurate.
Use Purchase Frequency Rate and Average Order Value
It's a slightly complicated method of calculating customer lifetime value. Let's start with the formula of CLV.
Formula: CLV = Customer value x Average customer lifespan
Now, how to get the customer value and average customer lifespan? Analyze purchase history to determine the average customer lifespan. Generally, we take 1 to 3 years as an average customer lifespan.
Customer value is different from customer lifetime value. We calculate customer value through a different formula.
Customer value = Purchase frequency rate x average order value
We must calculate purchase frequency and average order value before calculating customer value.
Purchase frequency rate= the number of orders in a certain period/number of customers in a particular period
Average order value= Total sales / number of orders
Firstly, we must calculate the average order value and purchase frequency rate. Put both values in the formula to calculate customer value. Eventually, multiply customer value by the average customer lifespan to get customer lifetime value.
Multiply Profit by the Lifetime Value
It's another method of calculating CLV. To calculate it, we will use the formula:
CLV = lifetime value x profit margin
Firstly, we have to determine the lifetime value to calculate further. Here is the formula to get the lifetime value:
Lifetime Value = average customer lifespan x number of transactions x average order value.
Once you get the lifetime value, put it in the first formula to calculate CLV.
Use Calculation Tools
Instead of doing complex calculations manually, you can use various tools to calculate CLV. Some marketing platforms, online calculators, and software are used for this purpose. The tools and software even provide accurate results.
These tools access the purchasing history to calculate CLV. Some tools use artificial intelligence to analyze customers' purchasing behavior.
CLV Calculation Examples
Simple formula example: A customer generates $500 in revenue over three years. Your cost to acquire and serve them is $150. CLV = $500 - $150 = $350.
Purchase frequency and AOV example: Your average order value is $80, and customers order 4 times per year. Average customer lifespan is 5 years. Customer value = 4 x $80 = $320 per year. CLV = $320 x 5 = $1,600.
With profit margin: If your profit margin is 25 percent and lifetime value is $1,600, CLV (profit-based) = $1,600 x 0.25 = $400.
Strategies to Improve CLV
- Loyalty programs: Reward repeat purchases with points, tiers, or exclusive access
- Subscription options: Recurring revenue increases predictability and CLV
- Upselling and cross-selling: Suggest complementary products at checkout
- Post-purchase engagement: Follow-up emails, surveys, and support build lasting relationships
- Personalization: Tailored recommendations and offers increase order frequency
- Reducing churn: Address pain points, simplify returns, and improve customer service
Track these strategies and segment CLV by acquisition channel to understand where your best customers come from. Use this to optimize marketing spend and product assortment. Recalculate CLV periodically as customer behavior and market conditions change. Use CLV to set acquisition budgets and evaluate marketing channels. High-CLV segments deserve more investment in retention and experience. Prioritize these customers in your product and support roadmap. CLV-driven decisions lead to more sustainable growth.
