Can we add a Calculated Custom Field which calculates other field values here.

[Akshith Kumar]

How to create a Calculated Custom field in Jira which calculates other three custom field values and display in the current field? can someone explain all the steps.

I didn't find this type of field in Advanced fields as well

You would need a combination of a custom Field and then some form of scripting or automation that would calculate the values from other fields and place them in the custom field. Automation for Jira is one such option that has some amount of calculation functions.
