Calculate sum of values of 2 custom fields in other custom field in JIRA Cloud

[Greg Raddemann]

I'm using JIRA Cloud and don't have any plugins. I plan to create two new custom fields (e.g. Ease of Development and Business Impact) which will each have numeric values (1 through 4). I'd like to create a 3rd custom field that simply sums those two numbers for display/reporting/sorting.

Is this possible in JIRA Cloud without a plugin/add-on?

If a plugin is needed, which one? Any suggestions on how to actually do this would be greatly appreciated! I'm not a programmer and am by no means a JIRA expert.

Thank You.

You can build a Jira automation rule to add the value of two fields. You can refer to How to sum up attribute value of multiple assets in an Assets objects field and update it to another Jira field with Automation for the same.

Native functionality will not do this.  We typically implement this using the Jira Workflow Toolbox and a post function that allows you to run an arithmetic function. I am not aware of any way to do this in Cloud.
