Example
Your Q1 cohort of 2,500 new customers generated $312,500 within their first 180 days:
| Cohort | Customers | Revenue (180d) | LTV 180 |
|---|
| Q1 2024 | 2,500 | $312,500 | $125.00 |
| Q2 2024 | 2,800 | $378,000 | $135.00 |
| Q3 2024 | 2,200 | $308,000 | $140.00 |
If your average CAC is $45, the Q3 cohort’s 6-month LTV:CAC ratio is 3.1×—indicating healthy acquisition economics.
How It Works
LTV 180 calculates the average total revenue per customer within 180 days of their first purchase. This 6-month window captures two to three typical purchase cycles for most repeat-buy categories like consumables, skincare, and apparel—making it ideal for evaluating mid-term acquisition payback.
