| -------------------------------------------------------------------------------- | --------------------------------------------------------------------- |
| **Channel Spend**                                                                | Total advertising spend across all connected ad platforms             |
| [**Add Shipping Info**](/reference/metrics/funnel/conversions/add-shipping-info) | Count of shipping info submission events tracked by the Upstack pixel |

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

## Example

Your Shopify store spent **\$8,000 on ads** this month and generated **2,000 add shipping info events** during checkout.

| Stage             | Events | Cost per Event |
| ----------------- | ------ | -------------- |
| Initiate Checkout | 3,200  | \$2.50         |
| Add Shipping Info | 2,000  | \$4.00         |
| Add Payment Info  | 1,600  | \$5.00         |
| Purchase          | 1,200  | \$6.67         |

**Cost per Add Shipping Info** = \$8,000 ÷ 2,000 = **\$4.00**

## How It Works

This metric divides your total advertising spend by the number of times visitors submitted their shipping information during checkout, as tracked by the Upstack pixel. It provides visibility into the cost efficiency of moving shoppers through the shipping information stage—a critical mid-funnel checkpoint between checkout initiation and payment.
