📊 CLV Metrics
What is Customer Lifetime Value (CLV)?
Customer Lifetime Value (CLV or LTV) is the total gross profit a business expects to earn from a customer over the entire duration of their relationship. CLV is one of the most important metrics in business because it tells you how much each customer is worth. Knowing CLV helps determine sustainable customer acquisition costs and informs marketing budget decisions.
How to Use This CLV Calculator
Calculate customer lifetime value in 5 simple steps:
- Enter Average Order Value ($): Average purchase amount per transaction
- Enter Purchase Frequency: Number of purchases per year
- Enter Customer Lifespan (years): Average years a customer stays
- Enter Profit Margin (%): Your gross profit percentage
- Enter CAC ($): Customer Acquisition Cost (optional for ratio)
- Results show CLV, annual revenue, lifetime profit, and LTV:CAC ratio
Customer Lifetime Value Formulas
CLV = Average Order Value × Purchase Frequency × Customer Lifespan
Annual Revenue = Average Order Value × Purchase Frequency
Lifetime Profit = CLV × (Profit Margin / 100)
LTV:CAC Ratio = CLV / Customer Acquisition Cost
Payback Period = CAC / (Annual Revenue × Profit Margin) × 12 months
Real-World Example
Example: $100 AOV, 4 purchases/year, 3-year lifespan, 30% margin, $50 CAC:
Annual Revenue: $100 × 4 = $400
Customer LTV: $400 × 3 = $1,200
Lifetime Profit: $1,200 × 30% = $360
LTV:CAC Ratio: $1,200 ÷ $50 = 24:1
Payback Period: $50 ÷ ($400 × 30%) × 12 = 5 months
Why CLV Matters
Understanding customer lifetime value helps you:
- Set acquisition budgets - Know maximum CPA for profitability
- Improve retention - Focus on high-LTV segments
- Optimize marketing - Allocate spend to highest-value channels
- Drive growth - Balance acquisition with retention investments
Frequently Asked Questions
What is a good LTV:CAC ratio?
3:1 is the industry benchmark for sustainable growth. Below 1:1 means you're losing money on every customer. Above 5:1 indicates you may be under-investing in customer acquisition. The optimal range is 3:1 to 5:1.
How can I increase customer lifetime value?
Increase CLV by: improving product quality to reduce churn, implementing loyalty programs, using upsells and cross-sells to increase AOV, investing in customer success and onboarding, and personalizing the customer experience.
What's the difference between CLV and LTV?
CLV (Customer Lifetime Value) and LTV (Lifetime Value) are the same metric. Both represent the total gross profit a business expects to earn from a customer over their entire relationship.
Why use profit margin instead of revenue?
Revenue-based CLV doesn't account for costs. A $1,000 CLV at 10% margin = $100 profit. Same CLV at 50% margin = $500 profit. Using profit margin gives accurate unit economics for sustainable growth.
How long should I measure customer lifespan?
Customer lifespan depends on your business model. SaaS typically uses 3-5 years. Ecommerce varies widely (1-10 years). Use historical data or industry benchmarks if you don't have enough history yet.
