It's hard to say, because we never know what we're going to find under the hood until we get started. In many cases, there are explicit returns by achieving goals like better tax efficiency, for example, but most clients would also tout the implicit benefit of working with a trusted adviser with no conflicts of interest who can answer many of the questions that others cannot or will not.
Costs depend on complexity and whether or not you would like to meet with an adviser to review or implement the plan. Some people just want a one-time meeting, sort of like going to the doctor for a check-up. Others work with us on an ongoing basis with regular meetings and potentially tax return preparation for them and their family. All of these things will impact the pricing of the service.
