<Tip>
  Google ROAS measures how much revenue you earn for every dollar spent on Google Ads.
</Tip>

## Formula

<Info>
  **Google ROAS** = [**Google Purchases Value**](/reference/metrics/advertising/google/google-conversions/google-purchases-value) ÷ [**Google Spend**](/reference/metrics/advertising/google/google-spend/google-spend)
</Info>

### Formula Components

| Metric                                                                                                        | Definition                                      |
| ------------------------------------------------------------------------------------------------------------- | ----------------------------------------------- |
| [**Google Purchases Value**](/reference/metrics/advertising/google/google-conversions/google-purchases-value) | Revenue from purchases attributed to Google Ads |
| [**Google Spend**](/reference/metrics/advertising/google/google-spend/google-spend)                           | Total amount spent on Google Ads                |

| **Type**        | Multiplier (displayed as Nx)      |
| **Data Source** | [Google Ads](/sources/google-ads) |
| **Aggregation** | Ratio                             |

## Example

**Your Google Ads campaign generated \$12,500 in revenue from \$2,500 in ad spend:**

| Metric                 | Value    |
| ---------------------- | -------- |
| Google Purchases Value | \$12,500 |
| Google Spend           | \$2,500  |
| **Google ROAS**        | **5.0x** |

A 5.0x ROAS means you earned \$5 in revenue for every \$1 spent on Google Ads.

***

## How It Works

Google ROAS divides revenue from purchases attributed to your Google Ads by your total ad spend. A ROAS of 3x means \$3 in revenue per \$1 spent. Higher ROAS indicates more efficient advertising performance.

## When to Use

| Scenario                          | Action                                              |
| --------------------------------- | --------------------------------------------------- |
| Evaluating campaign profitability | Compare ROAS against your target (e.g., 3x minimum) |
| Optimizing budget allocation      | Shift spend toward campaigns with higher ROAS       |
| Testing ad creatives              | Measure which variations drive better returns       |
| Setting bid strategies            | Use target ROAS bidding in Google Ads               |
