Calculate workload for a resource for a given time period

Is it possible to see the total workload for a given resource over a period of time? For example, I’d like to see the workload for Resource 1 for a given month. Then compare that with other months so I can decide how to best assign tasks to manage the workload of individual team members.

This kind of thing would also be useful to produce a project budget for each month… down to a per resource per month breakdown.
