I use those monkey-punching numbers and have the software generate an ungodly fee. Then I give the client a nice discount and they LOVE DISCOUNTS. I have used both methods and they all potentially generate a discussion with the client. 

The answer to the original question is that I get to charge more here in the San Francisco Area, then I would in the small coastal towns of Northern CA or in the area you might live in. YOU need to decide what YOUR costs are and what YOUR time is worth. There is no universal schedule of fees. 

Tax Tools has a possible tool (one of many) that you might like - The following screen is part of the Tax Fee Schedule and Justifier. Overall it is a wonderful piece of software, but I have never used this particular tool.
