How to Calculate Customer Lifetime Value in GA4

Customer Lifetime Value (LTV) is arguably the most important metric for any e-commerce business. It tells you how much revenue you can expect from each customer over their entire relationship with your brand.

What is Customer Lifetime Value?

LTV represents the total revenue a business can reasonably expect from a single customer account. It considers a customer's revenue value and compares that to the company's predicted customer lifespan.

The Simple LTV Formula

Breaking Down Each Component

• Average Order Value (AOV): Total revenue divided by number of orders
• Purchase Frequency: How often a customer buys (orders per year)
• Customer Lifespan: Average years a customer remains active

Calculating LTV in GA4

Google Analytics 4 doesn't have a built-in LTV report, but you can calculate it using custom explorations:

Step 1: Create a User Lifetime Exploration

1. Go to Explore → User Lifetime
2. Set your date range (recommend 12+ months)
3. Add dimensions: First user medium, First user campaign

Step 2: Add Revenue Metrics

Include these metrics in your exploration:

• Lifetime revenue per user
• Purchase revenue
• Purchases per user

Why LTV Matters

Understanding LTV helps you:

• Set appropriate customer acquisition budgets
• Identify your most valuable customer segments
• Optimize marketing spend across channels
• Make better decisions about retention vs. acquisition

Improving Your LTV

Once you know your LTV, focus on these strategies to improve it:

1. Increase AOV through bundling and upsells
2. Boost frequency with email marketing and loyalty programs
3. Extend lifespan through exceptional customer service
4. Reduce churn by identifying at-risk customers early
