| ----------------------- | --------------------------------------------------------- |
| **SUM**                 | Aggregation function that totals all custom event values  |
| **Custom Event Values** | Monetary value assigned to each custom event when tracked |

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

## Example

Your store tracked **\$12,500** in custom event value this month across 2,500 events:

| Event Name          | Value   | Count | Avg Value |
| ------------------- | ------- | ----- | --------- |
| quiz\_completed     | \$5,200 | 520   | \$10.00   |
| wishlist\_shared    | \$3,800 | 760   | \$5.00    |
| video\_watched      | \$2,100 | 700   | \$3.00    |
| size\_guide\_opened | \$1,400 | 520   | \$2.69    |

## How It Works

Custom Event Value sums the monetary value assigned to each custom event tracked by the Upstack pixel. Custom events are user-defined tracking events you configure for actions specific to your business—such as completing a quiz, sharing a wishlist, or watching a product video. Each event can include a custom value representing expected revenue impact or conversion likelihood. This metric helps quantify the total engagement value from custom interactions across your marketing campaigns.
