# Cost per Submit Application: Acquisition Efficiency

> Track cost per submit application event. Measure acquisition efficiency for application-based conversion funnels using Upstack pixel tracking.

<Tip>
  Cost per Submit Application measures the average ad spend required to generate one application submission tracked by the Upstack pixel.
</Tip>

## Formula

<Info>
  **Cost per Submit Application** = **Channel Spend** ÷ **Submit Application Events**
</Info>

### Formula Components

| Metric                                                                                    | Definition                                                 |
| ----------------------------------------------------------------------------------------- | ---------------------------------------------------------- |
| **Channel Spend**                                                                         | Total advertising spend across all connected ad platforms  |
| [**Submit Application Events**](/reference/metrics/funnel/conversions/submit-application) | Total application submissions tracked by the Upstack pixel |

| **Type**        | Currency                |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Ratio                   |

## Example

Your loan application funnel received **847 submit application events** last month. Your total ad spend across Meta and Google was **\$12,500**.

| Metric                          | Value       |
| ------------------------------- | ----------- |
| Total Channel Spend             | \$12,500    |
| Submit Application Events       | 847         |
| **Cost per Submit Application** | **\$14.76** |

***

## How It Works

This metric divides your total advertising spend by the number of application submissions tracked by the Upstack pixel. It provides a unified cost efficiency view across all ad platforms, helping you understand the true acquisition cost for application-based conversion funnels.

## When to Use

| Scenario                       | Action                                                                     |
| ------------------------------ | -------------------------------------------------------------------------- |
| Evaluating campaign efficiency | Compare cost per application across campaigns to identify top performers   |
| Budget allocation decisions    | Shift spend toward channels with lower cost per application                |
| Funnel optimization            | High cost per application may indicate targeting or landing page issues    |
| Benchmarking over time         | Track trends to ensure acquisition efficiency improves as campaigns mature |
