How to show Company Override Billing Rate on a Project

If you use Company Billing rate override on a project, how can you surface that rate amount?  Along that same thought, does anyone know what the field references are if I needed to try to bring it in for text mode?  

Use Case: I am trying to created a calculated field that shows [A] Scoped Hours x [B] company role billing rate = Scoped Revenue. Scoped Hours is a custom form field. 

Thank you!
