What Is Lifetime Value?
Customer Lifetime Value (LTV) is the predicted net profit a business can expect to earn from a
single customer over the entire duration of their relationship. It helps you:
- Determine how much to spend on customer acquisition
- Forecast long-term revenue
- Identify your most profitable customer segments
- Focus your retention efforts where they’ll matter most
How to Determine Lifetime Value: The Basic Formula
LTV = Average Purchase Value × Purchase Frequency × Customer Lifespan
Let’s break that down into steps:
1. Calculate Average Purchase Value
Formula:
Total Revenue ÷ Total Number of Purchases
Example: If your business made $120,000 from 2,000 purchases, Average Purchase Value =
$120,000 ÷ 2,000 = $60
2. Determine Purchase Frequency
Formula:
Total Number of Purchases ÷ Total Number of Customers
Example: 2,000 purchases ÷ 400 customers = 5
3. Measure Customer Lifespan
Formula:
Sum of Customer Lifespans ÷ Number of Customers
Example: Average Customer Lifespan = 3 years
Final Calculation Example
LTV = $60 × 5 × 3 = $900
Advanced Lifetime Value Calculation: LTV With Gross Margin
LTV = (Average Purchase Value × Purchase Frequency × Customer Lifespan) × Gross Margin
If Gross Margin = 70%, then LTV = $900 × 0.70 = $630
Why Is LTV So Important?
- Smarter Marketing Spend
- Business Valuation

acquiring a customer.
