LTV Calculator: How to Measure Customer Lifetime Value
What is LTV (Customer Lifetime Value)?
LTV, or Customer Lifetime Value, is the total revenue a business can expect from a customer throughout their entire relationship. Instead of looking only at one-time purchases, LTV helps you understand the long-term profitability of each customer.
In simple terms:
LTV = Average Purchase Value × Purchase Frequency × Customer Lifespan
For example, if your customer spends $50 per purchase, buys 5 times per year, and stays with your business for 3 years, then:
LTV = $50 × 5 × 3 = $750
Why Use an LTV Calculator?
An LTV Calculator saves time and gives accurate insights by automating the formula. Businesses use it to:
- Optimize marketing spend – Know how much you can afford to acquire a new customer.
- Improve retention strategies – Focus on keeping high-value customers longer.
- Forecast revenue growth – Predict long-term income based on existing customer behavior.
- Segment customers – Identify your most profitable audience groups.
How to Calculate LTV Step-by-Step
- Find the average purchase value – Total revenue ÷ number of purchases.
- Calculate purchase frequency – Number of purchases ÷ number of customers.
- Measure customer lifespan – Average time (in years or months) a customer stays with you.
- Apply the formula – Multiply all three values together.
Example:
- Total revenue = $100,000
- Number of purchases = 2,000
- Customers = 500
- Customer lifespan = 4 years
- Average purchase value = $100,000 ÷ 2,000 = $50
- Purchase frequency = 2,000 ÷ 500 = 4
- LTV = $50 × 4 × 4 = $800
