# Blended Conversions ROAS: Cross-Platform Efficiency

<Tip>
  Blended Conversions ROAS measures the revenue generated from all conversion types across all ad platforms for every dollar spent on advertising.
</Tip>

## Formula

<Info>
  **Blended Conversions ROAS** = **Blended All Conversions Value** ÷ **Blended Spend**

### Formula Components

| Metric                                                                                                                        | Definition                                               |
| ----------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------- |
| [**Blended All Conversions Value**](/reference/metrics/advertising/blended/blended-conversions/blended-all-conversions-value) | Total revenue from all conversion types across platforms |
| [**Blended Spend**](/reference/metrics/advertising/blended/blended-spend/blended-spend)                                       | Total amount spent on advertising across all platforms   |

| Metadata        |                                                                                                     |
| --------------- | --------------------------------------------------------------------------------------------------- |
| **Type**        | Multiplier                                                                                          |
| **Data Source** | [Meta Ads](/sources/facebook-ads), [Google Ads](/sources/google-ads), [TikTok Ads](/sources/tiktok) |
| **Aggregation** | Ratio                                                                                               |

***

## Example

Your campaigns spent **\$10,000** across all platforms and generated **\$45,000** in conversion value from all event types.

| Metric                        | Value    |
| ----------------------------- | -------- |
| Blended All Conversions Value | \$45,000 |
| Blended Spend                 | \$10,000 |
| **Blended Conversions ROAS**  | **4.5x** |

***

## How It Works

This metric aggregates all conversion events (purchases, signups, leads, etc.) across Meta, Google, and TikTok Ads, then divides by total spend. It provides a holistic view of advertising efficiency by including all conversion types, not just purchases.
