What is LTV (Customer Lifetime Value)?
Customer Lifetime Value (LTV or CLV) is the predicted total net revenue a business earns from a customer throughout the entire business relationship. Formula: LTV = Average Order Value × Purchase Frequency × Customer Lifespan × Gross Margin %. Why it matters: LTV helps ecommerce businesses determine how much they can spend on customer acquisition (CAC) while remaining profitable. The industry benchmark for a healthy LTV:CAC ratio is 3:1.
Customer Lifetime Value (LTV) is one of the most important metrics for ecommerce businesses. It tells you how much profit you can expect from a customer over their entire relationship with your brand. Understanding your LTV helps you:
- Set marketing budgets: Know how much you can spend to acquire customers profitably
- Prioritize retention: Understand the value of keeping customers longer
- Optimize pricing: Make data-driven decisions about discounts and promotions
- Evaluate channels: Compare which marketing channels bring the most valuable customers
Use the calculator below to calculate your LTV, LTV:CAC ratio, and payback period. The tool includes benchmarks and actionable insights to help you improve your customer value.

What is Customer Lifetime Value (LTV)?
Customer Lifetime Value (LTV) represents the total profit a business can expect to earn from a single customer throughout their entire relationship. It's calculated by multiplying:
- Average Order Value (AOV): How much a customer spends per order
- Purchase Frequency: How many times they buy per year
- Customer Lifespan: How many years they remain a customer
- Gross Margin: Your profit percentage after cost of goods
Why LTV:CAC Ratio Matters
The LTV:CAC ratio compares how much a customer is worth versus how much it costs to acquire them. A healthy ratio is typically 3:1 or higher, meaning each customer is worth at least 3 times what you spent to acquire them. This ratio helps you:
- Determine if your marketing spend is profitable
- Identify opportunities to scale customer acquisition
- Spot problems before they become costly
How to Use Your LTV Results
Once you've calculated your LTV, use it to:
- Set CAC targets: If your LTV is $150, you can afford to spend up to $50 per customer (3:1 ratio)
- Prioritize improvements: Focus on the metric with the biggest impact (AOV, frequency, or lifespan)
- Test strategies: Model how changes in pricing, retention, or acquisition affect your LTV
- Compare segments: Calculate LTV for different customer groups to find your most valuable segments
