Customer lifetime value (CLV) calculation in Digital Marketing - Full Explanation

Introduction

Businesses often struggle to understand how much each customer is truly worth over time. Knowing this helps them decide how much to spend on marketing and how to keep customers happy.

Explanation

What is CLV

Customer lifetime value (CLV) estimates the total money a business expects to earn from a customer during their entire relationship. It helps businesses focus on long-term profits rather than just one sale.

CLV measures the total value a customer brings over time, not just a single purchase.

Basic CLV formula

The simplest way to calculate CLV is to multiply the average purchase value by the number of purchases a customer makes in a year, then multiply by the average number of years they stay a customer. This gives an estimate of total revenue from that customer.

Basic CLV = Average purchase value × Purchase frequency × Customer lifespan.

Considering profit margin

To understand real value, businesses subtract costs from revenue. Multiplying CLV by the profit margin shows how much profit a customer generates, not just sales.

Profit margin adjusts CLV to reflect actual profit, not just revenue.

Discounting future value

Money earned in the future is worth less today. Businesses use a discount rate to reduce future earnings to their present value, making CLV more accurate.

Discounting accounts for the time value of money in CLV.

Using CLV in marketing

Knowing CLV helps businesses decide how much to spend to acquire and keep customers. Higher CLV means more budget can be spent on marketing and customer service.

CLV guides smart spending on customer acquisition and retention.

Real World Analogy

Imagine a coffee shop owner who wants to know how much each regular customer is worth. Instead of just counting one coffee purchase, they think about how many coffees the customer buys each week and how many years they keep coming back.

What is CLV → Thinking about the total money a regular customer spends over many visits, not just one.

Basic CLV formula → Multiplying the price of one coffee by how many coffees the customer buys weekly and how many years they stay loyal.

Considering profit margin → Remembering that the coffee shop has costs like beans and rent, so profit is less than total sales.

Discounting future value → Knowing that money earned next year is not as valuable as money earned today.

Using CLV in marketing → Deciding how much to spend on loyalty cards or promotions based on how valuable a regular customer is.
