Hi @Pavan Reddy,

You can get it done by the Automation for Jira add-on, have a look at math-functions.

or use Script runner add-on for reference see the similar question.

Hope this helps you.

Thanks,
Ram.

Both Automation and ScriptRunner work in Cloud.

They do not quite do "scripted fields", but they will allow you to create post-functions and automations that can add up two fields and populate the third (note - not on screen as the user enters them, but after they commit a change, Cloud doesn't support that)
