Dear Kevin, Sadly, I can't give you a clear and precise answer. You need to keep in mind that multiple people can log hours to the same task, and even the same person can log hours as different roles (with different rates). So behind the scenes every single hour entry is calculating a rate, but certainly from an hour based report you can't rely on a single hourly rate (and a task based report could only give you one rate figure). Frustratingly, even the hour based report gives you the role.billingPerHour of the primary assignee to the task/item, not necessarily of the person logging the time if multiple people are assigned. We went some way to reverse engineering it by dividing an individual's cost contribution to a task by the number of hours they'd logged, but then realised we were getting null results for rate if they hadn't logged any hours against a task yet and gave up. I logged a request in the idea exchange to include an effective rate in the report engine, but to date I'm the only one who's voted for it!
