Output Modes and Metrics
Use CAC Calculator with consistent source data to produce reliable decisions for spend allocation, margin control, and scaling plans.
| Metric | How It Is Used | Typical Benchmark | Optimization Move |

| Primary Input | Core number driving final output | Validated campaign window | Standardize data source before analysis |
| Efficiency Ratio | Return per unit of spend | Above break-even | Cut low-intent traffic and weak creatives |
| Profit Signal | Positive vs negative economics | Consistent positive trend | Tune pricing, AOV, and conversion steps |
