Best practice for implementing calculation fields in Jira Forms with live updates

[Roy Maalouf]

Hello Community,

I’m working on a use case where I want to build a Jira form that includes calculation fields. The idea is that when a user enters numbers into certain fields, the calculation field should immediately display the result (e.g., totals, percentages) in real time, without the user having to submit the form first.

I’d like to ask:

• What is the best practice to implement this in Jira today?

• Is there a native way to achieve “live” calculations inside Jira forms, or do I need to rely on automation, scripting, or Marketplace apps?

• If Marketplace apps are the best route, which ones are commonly used for live calculation fields inside forms?

Has anyone implemented something similar successfully, and if so, how did you approach it?

Thanks in advance for your insights!
