## Example

You had **169 new subscribers** in January with an average first order of **\$45**.

| Metric                              | Value   | Notes                  |
| ----------------------------------- | ------- | ---------------------- |
| Subscription Initial Purchases      | 169     | New subscribers        |
| Avg First Order Value               | \$45    | Average initial order  |
| Subscription Initial Purchase Value | \$7,605 | New subscriber revenue |

***

## How It Works

This metric sums the value attribute from all first-time subscription orders. It captures revenue specifically from new subscriber acquisition, separate from recurring revenue.
