Create threshold and active days metrics and preview the results

November 3, 2026

GrowthBook 5.2 redesigns how you create metrics. There are now 12 metric types, including new threshold and active days metrics. You can also preview a metric's result on your warehouse data before you save it.

Metrics that used to take a recipe

You could measure these ideas before 5.2, but you had to know which settings to combine. The metric examples in the docs show two of these recipes:

  • The docs build "users who purchased multiple times" as a Proportion metric with a User Filter on Count of Rows set to >= 2.
  • The docs build active days per user as a Mean metric with Distinct Dates as the column.

In 5.2, threshold and active days are metric types of their own. A threshold metric answers questions such as "what percentage of users placed at least 2 orders?"

Check the result before you save

Run a preview in the new metric editor to see the metric's result on your warehouse data. Use it to confirm the metric returns the numbers you expect and to catch errors before you save.

Getting started

Log in to GrowthBook and create a new metric on one of your fact tables. Choose a metric type, such as threshold or active days. Run a preview and check the result before you save.
