CLV (Customer Lifetime Value)
CLV (Customer Lifetime Value) is a metric that shows how much money, on average, one customer brings to a company over the entire duration of their relationship. In other words, CLV helps a business understand a customer’s value in the long term, not just at the moment of the first purchase.
Why a Business Needs CLV
This metric allows for forecasting revenue from customers and planning customer acquisition costs. If a company knows how much money a customer brings “over their lifetime,” it can make more informed investments in marketing, loyalty programs, and service.
CLV helps to:
- Evaluate the profitability of investments in customer acquisition (CAC vs. CLV).
- Segment the audience and focus on the most valuable customers.
- Plan long-term sales and marketing strategy.
- Choose priority marketing channels.
CLV Calculation Formula
Several calculation methods exist, from simple to more detailed.
Basic Formula:
CLV = Average Purchase Amount × Number of Purchases per Month × Average Relationship Duration (in months)
For example, a customer buys for an average of 3,000 ₽ twice a month and stays with the company for 12 months.
CLV = 3,000 × 2 × 12 = 72,000 ₽.
This means one customer brings the company 72,000 ₽ in revenue over the entire relationship.
Extended Formula:
CLV = (Average Purchase Amount × Purchase Frequency × Average Relationship Duration) – CAC
Here, the metric CAC (Customer Acquisition Cost) is added to the calculation. This allows understanding not just revenue, but the customer’s actual profitability.
Example CLV Calculation
A company sells a subscription to an online service.
- Average Purchase Amount: 1,000 ₽ per month.
- Average Subscription Duration: 18 months.
- Customer Acquisition Cost (CAC): 3,000 ₽.
CLV = (1,000 × 18) – 3,000 = 15,000 ₽.
Thus, each customer brings the company an average of 15,000 ₽ in profit over their entire time using the service.
Calculation Mistakes and Limitations
- Oversimplified formulas. Calculating CLV based only on average purchase amount can underestimate important factors like seasonality or additional purchases.
- Ignoring customer churn. Customer lifespan varies by industry: years for banks, months for e-commerce.
- Ignoring segmentation. CLV differs greatly between customer categories: a premium audience can bring dozens of times more value than a mass-market one.
CLV and Other Metrics
CLV is closely related to other indicators:
- CAC (Customer Acquisition Cost) — helps determine if customer acquisition costs are recouped.
- LTV (Lifetime Value) — often used synonymously with CLV, though sometimes LTV refers to the theoretical maximum revenue from a customer, while CLV refers to the actual.
- ROI and ROMI — help assess marketing investment effectiveness, while CLV shows the customer’s value as an asset.
Tools for Calculating CLV
- Excel and Google Sheets — for simple calculations.
- CRM systems (amoCRM, Bitrix24) — automatic purchase tracking.
- Analytics services (e.g., Roistat) — allow accounting for all acquisition channels, costs, and repeat purchases.
Conclusion
CLV is a strategic metric that helps a business understand how much, on average, a customer brings over their entire relationship with the company. Correctly calculating CLV enables effective allocation of the marketing budget, evaluation of investment profitability, and building a long-term development strategy.
