Combine Events To Create A Custom Event

MTU Pricing Transition

Mixpanel is transitioning to a Monthly Tracked Users (MTU) billing system. The plans described in this article are legacy plans. Read this blog post to learn more about the switch to billing for Monthly Trackers Users.

Create custom combinations of events by making a custom event within Mixpanel.

Custom events allow you to define a group of users based on existing events and properties, and then integrate that group into Mixpanel reports.

Limits by Plan Type

Free: 1 Custom Event

Startup: 15 Custom Events

Enterprise: Unlimited Custom Events

Create a Custom Event

  1. Expand the Event dropdown in either an Insights, Funnels, Retention, or Formulas report.
  2. Select Create custom event.
  3. Select the events and properties you’d like to include.
  4. Name your custom event, and click Save custom event.


When naming your custom event, note that the UI will break when the URL passes 2,083 characters. Each event and selector adds to the URL length (selectors more so than events). The easiest way to break a custom event is with an "equals" operation that selects a lot of values.

Example Use Case

Imagine your business has two ways for users to spend money: they can purchase an item from your store or subscribe to a service that you offer.

You represent each of these actions with Mixpanel events named "Item purchased" and "Subscription created," respectively. Later, you decide that you want to setup a funnel to track how many users are logging in and then spending any money at all. So what do you do?

You can create a custom event containing "Item purchased" and "Subscription created," and then save it as "Spent money.” Now you can use the "Spent money" custom event as a funnel step just like a regular event. Then, any time a user performs an "Item purchased" or "Subscription created" action, they'll be included in that step. You can also use this new custom event in your other reports, such as Retention.
