how to add employee charge out rate and track task profitability

how to add employee charge out rate and track task profitability

Hi

I am trailing the software for my business. 

I want to have a number of tasks, and then users book time to the tasks. I have a target rate for each employee and a fixed budget for the task.

Therefore I want to track financial performance of each task. Is this possible? I do not seem able to put an employee rate or to track this?

Cheers
