## Unit Economics Analysis

### Customer Acquisition Cost (CAC)
Calculate total cost to acquire one customer:
- Marketing spend / New customers = CAC
- Include: ads, content, sales team, tools

**My CAC breakdown:**

### Lifetime Value (LTV)

**For Subscription:**
LTV = ARPU x Gross Margin x Customer Lifetime
Customer Lifetime = 1 / Churn Rate

**For Transactional:**
LTV = AOV x Purchase Frequency x Customer Lifespan x Gross Margin

**My LTV calculation:**
- Average revenue per user (ARPU): $
- Gross margin: %
- Average customer lifetime: months
- **LTV:** $
