| ------------------ | --------------------------------------------------------------- |
| **Orders**         | Total purchase events tracked by the Upstack pixel              |
| **P90\_threshold** | The 90th percentile of your historical order value distribution |

| **Type**        | Number                  |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Count                   |

## Example

Your Shopify store has a P90 AOV threshold of **\$275**. In January, you received **282 orders** above this threshold.

| Metric            | Value | Notes                 |
| ----------------- | ----- | --------------------- |
| Total Orders      | 2,820 | All tracked purchases |
| P90 AOV Purchases | 282   | Orders > \$275        |
| P90 Percentage    | 10%   | Top-tier order share  |

***

## How It Works

The Upstack pixel calculates the 90th percentile of your historical order values to establish the P90 threshold. Any order above this threshold is counted as a P90 AOV Purchase. This represents your top 10% of orders by value—your whale customers.
