Calculate the total value a customer brings to your business over their entire relationship. Understand CLV to optimize marketing spend, improve retention strategies, and maximize profitability.
Total revenue / number of purchases
Number of purchases / number of customers
1 / churn rate (e.g., 5% churn = 20 years)

Optional: for CLV:CAC ratio analysis
Customer Lifetime Value (CLV or LTV) represents the total revenue a business can expect from a single customer account throughout their relationship. It's one of the most important metrics for understanding customer profitability and making informed decisions about customer acquisition costs, retention investments, and marketing budgets. A higher CLV indicates that customers are more valuable to your business, justifying higher acquisition costs and retention efforts.
The basic CLV formula multiplies three key components: Average Purchase Value (how much customers spend per transaction), Average Purchase Frequency (how often they buy), and Average Customer Lifespan (how long they remain customers). By understanding and optimizing each component, businesses can significantly increase overall customer value. CLV is particularly valuable when compared to Customer Acquisition Cost (CAC)—a healthy business typically has a CLV:CAC ratio of at least 3:1, meaning customers generate three times more value than it costs to acquire them.
The average amount a customer spends per transaction.
APV = Total Revenue / Number of Purchases
Example: If you generated $100,000 from 500 purchases, your APV is $200. This metric helps you understand typical transaction sizes and identify opportunities for upselling or bundling.
How often customers make purchases within a time period.
APF = Number of Purchases / Number of Customers
Example: If 400 customers made 500 purchases, your APF is 1.25 purchases per customer. Increasing purchase frequency through loyalty programs or subscription models directly increases CLV.
The average time a customer continues buying from you.
ACL = 1 / Churn Rate
Example: If your monthly churn rate is 5% (0.05), your average customer lifespan is 20 months. Reducing churn through better service and engagement dramatically increases CLV.
Complete CLV Formula:
CLV = Average Purchase Value × Average Purchase Frequency × Average Customer Lifespan
Using the examples above: CLV = $200 × 1.25 × 20 months = $5,000 per customer
| Industry | Typical CLV Range | Average Lifespan | Key Factors |
|---|---|---|---|
| SaaS (B2B) | $5,000 - $50,000+ | 2-5 years | Monthly recurring revenue, low churn |
| E-commerce | $200 - $2,000 | 1-3 years | Repeat purchase rate, average order value |
| Subscription Box | $300 - $1,500 | 6-18 months | Monthly subscription, retention rate |
| Mobile Apps | $50 - $500 | 3-12 months | In-app purchases, engagement rate |
| Insurance | $5,000 - $20,000 | 5-10 years | Annual premiums, policy renewals |
| Automotive | $10,000 - $50,000 | 10-15 years | Vehicle purchases, service, parts |
| Banking | $2,000 - $10,000 | 10-20 years | Account fees, loan interest, services |
| Fitness/Gym | $500 - $2,000 | 1-2 years | Monthly membership, personal training |
CLV varies significantly by industry based on purchase frequency, transaction size, and customer loyalty. Understanding your industry benchmarks helps set realistic targets and identify improvement opportunities.

Focus acquisition efforts on high-value customer segments:
| CLV:CAC Ratio | Business Health | Interpretation | Action Required |
|---|---|---|---|
| Less than 1:1 | Critical | Losing money on every customer | Immediate action needed to reduce CAC or increase CLV |
| 1:1 to 2:1 | Poor | Barely profitable, unsustainable | Optimize acquisition costs and retention strategies |
| 2:1 to 3:1 | Acceptable | Profitable but room for improvement | Focus on increasing CLV through retention |
| 3:1 to 5:1 | Good | Healthy, sustainable business model | Maintain current strategies, test growth initiatives |
| Greater than 5:1 | Excellent | Very profitable, strong unit economics | Consider increasing marketing spend to accelerate growth |
The CLV:CAC ratio is a critical metric for business sustainability. A ratio of 3:1 or higher indicates healthy unit economics, meaning you're generating three dollars of customer value for every dollar spent on acquisition. If your ratio is below 3:1, focus on either reducing acquisition costs or increasing customer lifetime value through retention and upselling strategies.
Don't calculate a single CLV for all customers. Segment by acquisition channel, product category, customer demographics, or behavior patterns. Different segments often have dramatically different CLVs, and understanding these differences helps you allocate resources more effectively. High-value segments may justify higher acquisition costs and more personalized retention efforts.
The most accurate CLV calculations use actual historical customer data rather than estimates. Track cohorts of customers over time to see real purchase patterns, retention rates, and lifetime values. This historical approach is more reliable than predictive models, especially for established businesses with sufficient data. For new businesses, start with estimates but refine them as you gather real data.
The basic CLV formula calculates revenue, but what really matters is profit. Calculate CLV using gross profit (revenue minus cost of goods sold) rather than total revenue to get a more accurate picture of customer value. This is especially important for businesses with varying profit margins across products or services. A customer who generates $10,000 in revenue at 20% margin is less valuable than one who generates $8,000 at 40% margin.
For sophisticated CLV analysis, apply a discount rate to future cash flows. A dollar earned today is worth more than a dollar earned in three years. This is particularly important for businesses with long customer lifespans or subscription models. Use your company's cost of capital or required rate of return as the discount rate. This approach provides a more accurate net present value of customer relationships.
CLV isn't a static metric—it changes as your business evolves, market conditions shift, and customer behavior changes. Recalculate CLV quarterly or at least annually to ensure your strategies remain aligned with current customer value. Track trends over time to identify whether your initiatives are successfully increasing CLV. Regular updates also help you spot problems early, such as declining retention rates or decreasing purchase frequency.
