Customer lifetime value

What is Customer lifetime value?

Customer lifetime value (CLV or LTV) is the total value — usually revenue or contribution margin — that a single customer is expected to generate over the entire relationship with your store. A simple model is average order value × purchase frequency × average customer lifespan. If you want a profit figure rather than revenue, multiply by your gross margin so you are measuring what actually reaches the bottom line.

Why does Customer lifetime value matter?

CLV tells you what a customer is worth over time, not just at the first purchase. That is critical because it sets the ceiling for how much you can pay to acquire a customer. An LTV:CAC ratio of around 3:1 is widely cited as a healthy benchmark in ecommerce. Once you know your CLV, you can bid more aggressively on ads for customers who stay with you, instead of blindly optimizing for the cheapest first sale.

Common use cases

• Set a realistic customer-acquisition budget based on the LTV:CAC ratio.
• Segment customers by expected value so VIP customers get special offers and loyalty perks.
• Assess whether subscription or repeat-purchase models can raise purchase frequency and therefore CLV.
• Prioritize efforts to reduce churn, since retention is often cheaper than acquisition.
• Calculate when a customer breaks even against your acquisition costs.

Shopify perspective

Shopify Analytics shows repeat-purchase rate and customer cohorts, and under customer segments you can filter on a predicted spend tier (high, medium, low). Use the segments to target email and ad flows toward your most valuable customers. For a more precise CLV calculation — with margin and time horizon — most stores export data via reports or an analytics app rather than relying on a single default figure.
