LTV:CAC = Customer Lifetime Value / Customer Acquisition Cost
A 3:1 ratio is often used as a rough target, but the right threshold depends on margins, payback period, and growth stage. Use the calculator to test realistic retention assumptions.
Définitions des métriques
Ce que le ratio peut signifier
| Ratio | Interpretation | Next step |
|---|---|---|
| Below 1:1 | Acquisition costs more than the customer is worth | Fix retention or acquisition before scaling |
| 1:1 to 2:1 | Potentially viable, but thin | Improve onboarding, upsells, or conversion quality |
| 3:1 or higher | Often healthy for scaling | Watch payback and saturation as spend rises |

- Payback period, to see how long it takes to recover spend.
- ROAS, to see the short-term revenue signal.
- Retention and churn, because a high CAC can still work with strong lifetime value.
