CLV Formulas
Simple CLV
CLV = Average Purchase Value × Purchase Frequency × Customer Lifespan
Example:
- Average purchase: $100
- Purchases per year: 4
- Customer lifespan: 3 years
- CLV = $100 × 4 × 3 = $1,200
CLV with Margin
CLV = (Average Purchase × Frequency × Lifespan) × Profit Margin
Example:
- Revenue CLV: $1,200
- Profit margin: 30%
- CLV = $1,200 × 0.30 = $360
CLV with Churn
CLV = Average Revenue per User / Churn Rate
Example (subscription):
- ARPU: $50/month
- Monthly churn: 5%
- CLV = $50 / 0.05 = $1,000
CLV:CAC Ratio
| Ratio | Meaning |
|---|---|
| 1:1 | Break even (bad) |
