CLV (Customer Lifetime Value)

Homepage Glossary 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.
