How to create new column in tableau with formula calculation

Question

I am really new to the tableau. Can someone help out and advise how to create new column inside table with formula calculation. enter image description here

Formula: (Answered interactions – Interactions that miss service level) / (Answered interactions + Abandoned interactions + Flow-outs)

Answer 1

You won't be able to display it on the same sheet if you have [Metric Name] in the view. But you can do it on another sheet and place them side by side on a dashboard.

count(if [Metric Name] = 'Answered interactions' then [Count] end)

This will isolate just the Answered interactions counts. Follow this pattern for the rest of the formula.
