# Subscription Churned Value: MRR Lost to Churn

> Track the monetary value of churned subscriptions. Measure MRR attrition from subscriber loss.

<Tip>
  Subscription Churned Value totals the MRR lost from churned subscriptions.
</Tip>

## Formula

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

### Formula Components

| Metric                           | Definition                            |
| -------------------------------- | ------------------------------------- |
| **value**                        | The MRR of each churned subscription  |
| **subscription\_churned events** | Events fired when subscriptions churn |

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

***

## Example

You had **89 churned subscriptions** in January with an average MRR of **\$65**.

| Metric                     | Value   | Notes              |
| -------------------------- | ------- | ------------------ |
| Subscription Churned       | 89      | Lost subscriptions |
| Avg Churned MRR            | \$65    | Average lost value |
| Subscription Churned Value | \$5,785 | Total MRR lost     |

***

## How It Works

This metric sums the value attribute from all subscription\_churned events. The value represents the monthly recurring revenue that was lost, helping you understand the revenue impact of churn.

## When to Use

| Scenario                  | Action                                  |
| ------------------------- | --------------------------------------- |
| Revenue attrition         | Track MRR lost to churn                 |
| Net MRR calculation       | Factor lost MRR into net revenue growth |
| High-value churn analysis | Identify valuable subscribers at risk   |
| Retention ROI             | Justify retention program investment    |
