## Example

New customers generated **\$7,000** CM4 from **\$50,000** net revenue.

| Component      | Value    | Calculation              |
| -------------- | -------- | ------------------------ |
| NC CM4         | \$7,000  | Operating profit         |
| NC Net Revenue | \$50,000 | Revenue base             |
| **NC CM4 %**   | **14%**  | \$7,000 ÷ \$50,000 × 100 |

## How It Works

NC CM4 % shows the operating profit margin from new customer acquisition. A positive NC CM4 % means you're profitable on first orders. Compare against RC CM4 % to understand how profitability changes as customers become repeat buyers.
