Customer Lifetime Value (LTV) Calculator
Use this calculator to estimate the total revenue a business can reasonably expect from a single customer account throughout their relationship with the company. Understanding LTV is crucial for strategic planning, marketing budget allocation, and customer retention efforts.
The average amount a customer spends per transaction.
The average number of times a customer makes a purchase in a year.
The average number of years a customer continues to purchase from your business.
The percentage of revenue that is profit after deducting the cost of goods sold.
The average cost to acquire one new customer. (Optional, for LTV:CAC ratio)
Understanding Customer Lifetime Value (LTV)
Customer Lifetime Value (LTV) is a critical metric that estimates the total revenue a business can expect from a single customer account throughout their entire relationship with the company. It's not just about a single transaction; it's about the long-term profitability of each customer.
Why is LTV Important?
- Strategic Planning: LTV helps businesses understand the long-term value of their customer base, informing decisions about product development, marketing strategies, and customer service.
- Marketing Budget Allocation: By knowing the LTV, companies can determine how much they can afford to spend on acquiring new customers (Customer Acquisition Cost – CAC) while remaining profitable. A healthy LTV:CAC ratio (ideally 3:1 or higher) indicates sustainable growth.
- Customer Retention: High LTV often correlates with strong customer loyalty. Businesses can focus on strategies to increase customer lifespan and purchase frequency, which directly boosts LTV.
- Profitability Insights: LTV provides a clearer picture of a customer's true worth, moving beyond immediate sales figures to reveal the underlying profitability of customer relationships.
How the LTV Calculator Works
Our calculator uses a common formula to estimate LTV, incorporating several key variables:
- Average Purchase Value: This is the average amount of money a customer spends each time they make a purchase from your business.
- Average Purchase Frequency: This represents how often, on average, a customer makes a purchase within a given period (usually a year).
- Average Customer Lifespan: This is the estimated number of years a customer continues to do business with your company.
- Gross Margin Percentage: This is the percentage of revenue left after subtracting the cost of goods sold. It reflects the profit margin on each sale.
- Customer Acquisition Cost (CAC): While not directly part of the LTV calculation, CAC is crucial for understanding the profitability of your customer base. It's the total cost of sales and marketing efforts needed to acquire one new customer.
The Formula:
First, we calculate the Customer Value (CV):
Customer Value (CV) = Average Purchase Value × Average Purchase Frequency
Then, we calculate the Lifetime Value (LTV):
Lifetime Value (LTV) = Customer Value × Average Customer Lifespan × Gross Margin Percentage (as a decimal)
If provided, we also calculate the LTV:CAC Ratio:
LTV:CAC Ratio = Lifetime Value / Customer Acquisition Cost
Example Calculation:
Let's say a business has the following metrics:
- Average Purchase Value: $50
- Average Purchase Frequency: 3 times per year
- Average Customer Lifespan: 5 years
- Gross Margin Percentage: 60%
- Customer Acquisition Cost (CAC): $30
Step 1: Calculate Customer Value (CV)
CV = $50 (APV) × 3 (APF) = $150
Step 2: Calculate Lifetime Value (LTV)
LTV = $150 (CV) × 5 (ACL) × 0.60 (GM as decimal) = $450
Step 3: Calculate LTV:CAC Ratio
LTV:CAC Ratio = $450 / $30 = 15:1
This example shows that for every dollar spent on acquiring a customer, the business generates $15 in lifetime value, indicating a very healthy and profitable customer relationship.
