Questions.
- Why 3:1 LTV:CAC?
- 3:1 leaves room for overhead, payback time and forecast error. Spending to breakeven LTV means any surprise (returns, churn, rising CPMs) pushes you underwater.
- What repeat rate should I use?
- Share of orders from returning customers over the last 90-180 days. If unknown, most DTC categories sit between 20% and 45%.
These are estimates. Your order data isn't.
