# End an Experiment

An A/B test finishes in one of two ways: you end it yourself, or it reaches the end date you configured. Either way, the last step is the same — choose the winning variant.

## End an Experiment Manually

<Steps>
  <Step title="Open the configuration screen">
    Open the experiment and click **Configure Experiment**. The **End Experiment** button sits in the top-right controls.
  </Step>

  <Step title="Review the results">
    The Select Winning Variant dialog shows each group with its average value, total, and sessions.

    </Frame>
  </Step>

  <Step title="Choose a winner">
    The variant with the highest average value is selected by default. Choose a different one if you want, or select **No winning variant** to close the test without declaring one.
  </Step>

  <Step title="Confirm">
    Click **End Experiment**. The status changes to **Completed**.
  </Step>
</Steps>

## When an Experiment Ends Automatically

An experiment ends on its own when the end date arrives. Experro emails the recipients configured on the **Duration** step.

The experiment then appears as **Completed** in the list with a caution icon beside its name, showing that it still needs a decision.

Open it and you will see a banner:

> The experiment has ended. Click Conclude Experiment to choose the winning variant and conclude the experiment.

Click **Conclude Experiment** to open the same Select Winning Variant dialog and finish the process.

## After an Experiment Ends

* Configuration becomes read-only.
* **Pause** and **End Experiment** are removed. **Clone** and **Delete** remain.
* Visitors previously enrolled see the control experience and become eligible for other experiments on their next visit.

<Note>
  Personalization experiments cannot be ended manually. When they reach their end condition they return to **Draft** instead of completing.
</Note>

<Warning>
  Ending an experiment is final. To keep collecting data, pause it instead.
</Warning>
