> Track the monetary value of plan upgrades. Measure expansion MRR from upsells.

<Tip>
  Subscription Upgraded Value totals the expansion MRR from plan upgrades.
</Tip>

## Formula

<Info>
  **Subscription Upgraded Value** = **SUM** ( value ) **FROM** subscription\_upgraded events
</Info>

### Formula Components

| Metric                            | Definition                            |
| --------------------------------- | ------------------------------------- |
| **value**                         | The MRR increase from each upgrade    |
| **subscription\_upgraded events** | Events fired when subscribers upgrade |

| Metadata        |                         |
| --------------- | ----------------------- |
| **Type**        | Currency                |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Sum                     |

***

## Example

You had **156 upgrades** in January with an average MRR increase of **\$35**.

| Metric                      | Value   | Notes                |
| --------------------------- | ------- | -------------------- |
| Subscription Upgraded       | 156     | Plan upgrades        |
| Avg Upgrade Value           | \$35    | Average MRR increase |
| Subscription Upgraded Value | \$5,460 | Total expansion MRR  |

***

## How It Works

This metric sums the value attribute from all subscription\_upgraded events. The value represents the incremental MRR from upgrading to a higher-tier plan, capturing expansion revenue.

## When to Use

| Scenario               | Action                                   |
| ---------------------- | ---------------------------------------- |
| Expansion MRR tracking | Monitor revenue from upgrades            |
| Net MRR calculation    | Factor expansion into net revenue growth |
| Upsell campaign ROI    | Calculate return on upsell investments   |
| Product tier analysis  | Compare upgrade values across plans      |
