What is Customer Lifetime Value (CLV)?
Customer Lifetime Value (also called LTV or CLTV) is a prediction of the total revenue a business can expect from a single customer account throughout the entire business relationship. It helps businesses understand how much they should invest in acquiring and retaining customers.
CLV is one of the most important metrics for any business because it shifts focus from short-term transactions to long-term customer relationships. Understanding CLV helps you make smarter decisions about marketing spend, customer service investments, and product development.
The CLV Formula
CLV = Average Purchase Value x Purchase Frequency x Customer Lifespan
For a more sophisticated calculation that accounts for profit margins and the time value of money:
Profit-Based CLV = (Avg Purchase x Frequency x Lifespan) x Profit Margin
How to Use This Calculator
Enter Average Purchase Value
The average amount a customer spends per transaction. Calculate this by dividing total revenue by number of purchases.
Enter Purchase Frequency
How many times per year a typical customer makes a purchase from your business.
Enter Customer Lifespan
The average number of years a customer continues to buy from you before churning.
Add Optional Metrics
Include profit margin for profit-based CLV, acquisition cost for CLV:CAC ratio, and discount rate for NPV calculation.
Why CLV Matters
- Marketing Budget: Determines how much you can profitably spend to acquire customers
- Customer Segmentation: Identifies your most valuable customers for targeted marketing
- Business Valuation: CLV is a key metric investors use to value companies
- Retention Focus: Highlights the long-term value of keeping customers happy
- Resource Allocation: Helps prioritize which customers deserve more attention
CLV to CAC Ratio
The CLV:CAC ratio shows the relationship between customer lifetime value and acquisition cost. This ratio is crucial for understanding business health:
- Below 1:1 - You're losing money on each customer. Unsustainable.
- 1:1 to 3:1 - Breaking even or slight profit. Room for improvement.
- 3:1 to 5:1 - Healthy ratio. This is the sweet spot for most businesses.
- Above 5:1 - Excellent! But consider if you're under-investing in growth.
Pro Tip: Improving Your CLV
The fastest ways to improve CLV are: (1) increase average order value through upselling and cross-selling, (2) improve purchase frequency with engagement campaigns, and (3) extend customer lifespan through excellent service and loyalty programs. Even small improvements in each area compound significantly.
