<Info>
  **Signup Completed** = **COUNT** ( signup\_completed events )

### Formula Components

| Metric                       | Definition                                         |
| ---------------------------- | -------------------------------------------------- |
| **signup\_completed events** | Events fired when a user completes the signup flow |

| Metadata        |                         |

| **Type**        | Number                  |
| **Data Source** | [Upstack Pixel](/pixel) |
| **Aggregation** | Count                   |

## Example

Your application tracked **1,250 signup\_completed events** in January.

| Metric           | Value | Notes                    |
| ---------------- | ----- | ------------------------ |
| Signup Started   | 3,450 | Started signup flow      |
| Signup Completed | 1,250 | Finished registration    |
| Completion Rate  | 36.2% | Signup funnel conversion |

***

## How It Works

The Upstack pixel tracks `signup_completed` events when users successfully complete the registration flow. This typically fires after email verification or when the user reaches the welcome/onboarding screen.
