How to enable duration calculations in Gravity Forms with GravityMath

Estimated reading: < 1 minutes

Updated on April 23, 2026

GravityMath allows durations to be calculated. You can calculate average time, fastest time, and slowest time.

In order to calculate time, a Single Line Text field must be modified to use an Input Mask set to either “Duration (HH:MM:SS)” or “Duration (MM:SS)”.

Here’s how to set the appropriate Input Mask:

Click the “Single Line Text” button to add a text field
