| Field | Detail |
|---|---|
| Definition | Payback period measures how long it takes to recover customer acquisition cost from customer revenue or gross profit. |
| Formula | CAC / Monthly Gross Profit per Customer |
| Why it matters | Payback period helps operators decide whether acquisition is sustainably fundable, especially in subscription, SaaS, and cash-sensitive growth models. |
| Good benchmark context | Payback period is strongest when paired with CAC, activation, churn, and gross margin so the benchmark reflects the full economic picture. |
Glossary entries should explain where interpretation goes wrong, not just repeat a formula.
| Common mistake |
|---|
| Calculating payback from revenue without accounting for margin. |
| Ignoring churn or delayed activation when estimating recovery time. |
| Using one payback target across very different pricing or contract models. |
