# Blended Cost per Lead: Cross-Platform Lead Acquisition Cost

> Track your blended cost per lead across Meta, Google, and TikTok ads. Measure lead acquisition efficiency with unified CPL metrics.

<Tip>
  Blended Cost per Lead measures how much you spend on average to acquire a single lead across all advertising platforms combined.
</Tip>

## Formula

<Info>
  **Blended Cost per Lead** = [**Blended Spend**](/reference/metrics/advertising/blended/blended-spend/blended-spend) ÷ [**Blended Leads**](/reference/metrics/advertising/blended/blended-conversions/blended-leads)
</Info>

### Formula Components

| Metric                                                                                        | Definition                                                |
| --------------------------------------------------------------------------------------------- | --------------------------------------------------------- |
| [**Blended Spend**](/reference/metrics/advertising/blended/blended-spend/blended-spend)       | Total advertising spend across all connected ad platforms |
| [**Blended Leads**](/reference/metrics/advertising/blended/blended-conversions/blended-leads) | Total lead conversions attributed across all ad platforms |

| Metadata        |                                                                                                     |

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

## Example

Your business spent **\$5,000** across all ad platforms last month and generated **250 leads**.

| Metric                    | Value       |
| ------------------------- | ----------- |
| Blended Spend             | \$5,000     |
| Blended Leads             | 250         |
| **Blended Cost per Lead** | **\$20.00** |

At **\$20 per lead**, you can evaluate whether your cross-platform lead generation strategy is cost-effective compared to industry benchmarks or your target acquisition costs.

***

## How It Works

Blended Cost per Lead aggregates total advertising spend from Meta, Google, and TikTok, then divides by the total number of leads attributed to those platforms. This provides a unified view of lead acquisition efficiency without platform-specific silos.
