</Info>

### Formula Components

| Metric                                                                                       | Definition                                        |
| -------------------------------------------------------------------------------------------- | ------------------------------------------------- |
| [**Meta Spend**](/reference/metrics/advertising/meta/meta-spend/meta-spend)                  | Total amount spent on Meta advertising campaigns  |
| [**Meta Unique Clicks**](/reference/metrics/advertising/meta/meta-clicks/meta-unique-clicks) | Number of unique people who clicked your Meta ads |

| Metadata        |                                   |
| --------------- | --------------------------------- |
| **Type**        | Currency                          |
| **Data Source** | [Meta Ads](/sources/facebook-ads) |
| **Aggregation** | Ratio                             |

## Example

Your Meta campaign spent **\$5,000** and received clicks from **2,000 unique users**.

| Metric                         | Value      | Calculation               |
| ------------------------------ | ---------- | ------------------------- |
| Meta Spend                     | \$5,000    | Total ad spend            |
| Meta Unique Clicks             | 2,000      | Unique people who clicked |
| **Meta Cost per Unique Click** | **\$2.50** | \$5,000 ÷ 2,000           |

***

## How It Works

Meta Cost per Unique Click divides your total ad spend by the number of unique individuals who clicked your ads. Unlike standard CPC which counts every click, this metric de-duplicates users who clicked multiple times, giving you the true cost to engage each unique person.

## When to Use

| Scenario                             | Action                                                        |
| ------------------------------------ | ------------------------------------------------------------- |
| Evaluating audience reach efficiency | Compare against standard CPC to see repeat click impact       |
| Optimizing retargeting campaigns     | Monitor if the same users click repeatedly without converting |
| Budget allocation decisions          | Identify campaigns with efficient unique user acquisition     |
| Audience fatigue analysis            | Rising cost per unique click may indicate creative exhaustion |
