Tracking conversion time in an experiment


I’m running an experiment and want to see if there is a significant difference between my control and treatment group in the time it takes for users to perform a specific action. When creating a funnel graph I see that the average time to convert is a pre-calculated metric. Is there a way to track this metric in my experiment? Or is there any other way to add conversion time between two events as a custom metric to my experiment?

Hey Aaron, are you collecting timestamps on the events you’re looking to measure? Do you have the derived properties functionality?

Hi Beth,


Thanks for the reply!


Yes I have the timestamps of the metrics. My data looks similar to for instance a shopping cart checkout:

Event: Added product to cart - Timestamp: 2024-06-01 10:00:00

Event: Purchased product - Timestamp: 2024-06-01  10:15:00

I then want to create a metric like ‘Cart to purchase time’, which for this particular user would be 15 minutes. This metric I then want to track in an experiment to see if users in the treatment group have a shorter purchase time compared to control.


Also, yes I have the derived properties functionality.
