</Tip>

## Formula

<Info>
  **Google Spend** = **SUM** ( Amount Spent )
</Info>

| Metadata        |                                   |
| --------------- | --------------------------------- |
| **Type**        | Currency                          |
| **Data Source** | [Google Ads](/sources/google-ads) |
| **Aggregation** | Sum                               |

## Example

A home goods retailer spent **\$12,450** on Google Ads in March across their campaigns:

| Campaign                | Spend   | Share of Budget |
| ----------------------- | ------- | --------------- |
| Shopping - Best Sellers | \$5,200 | 42%             |
| Search - Brand Terms    | \$3,100 | 25%             |
| Performance Max         | \$2,850 | 23%             |
| Display Remarketing     | \$1,300 | 10%             |

## How It Works

Google Spend is pulled directly from the Google Ads API and represents actual charges to your account. This includes all costs across Search, Shopping, Display, Video, and Performance Max campaigns. The metric updates as Google processes billing events.
