## Example

Your Shopify store has **\$10,800** subscription CM1 on **\$18,000** subscription revenue.

| Component              | Value    | Calculation         |
| ---------------------- | -------- | ------------------- |
| Subscription CM1       | \$10,800 | Gross margin        |
| Subscription Revenue   | \$18,000 | Revenue             |
| **Subscription CM1 %** | **60%**  | \$10,800 ÷ \$18,000 |

***

## How It Works

Subscription CM1 % shows product-level margin efficiency for subscriptions. Compare to overall CM1 % to understand if subscription orders are more or less profitable at the gross margin level.
