## Formula

<Info>
  **Cost per High AOV Purchase** = **Channel Spend** ÷ **High AOV Purchases**
</Info>

### Formula Components

| Metric                 | Definition                                                              |
| ---------------------- | ----------------------------------------------------------------------- |
| **Channel Spend**      | Total advertising spend across all connected ad platforms               |
| **High AOV Purchases** | Purchase events where order value exceeds your configured AOV threshold |

| Metadata        |                         |
| --------------- | ----------------------- |
| **Type**        | Currency                |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Ratio                   |

***

## Example

Your Shopify store spent **\$25,000 on ads** this month. You track purchases where order value exceeds **\$150** as high AOV purchases:

| Order Value Segment | Purchases | Share    |
| ------------------- | --------- | -------- |
| High AOV (>\$150)   | 320       | 26%      |
| Standard AOV        | 900       | 74%      |
| **Total**           | **1,220** | **100%** |

**Cost per High AOV Purchase** = \$25,000 ÷ 320 = **\$78.13**

***

## How It Works

This metric divides your total advertising spend by high AOV purchase events tracked by the Upstack pixel. High AOV purchases are orders where the cart value exceeds a predefined threshold based on your store's average order value. The metric helps identify how efficiently your ad campaigns drive premium, high-margin transactions from your Shopify store.
