I am thinking of becoming an actuary.
Cost savings result from two factors.
First, I have very low overhead costs, since fees do not need to cover costs of senior partners, managers, etc. Second, I accept a lower fee in exchange for working with clients on a telecommuting basis. That is, I generally do not work on site. My business is set up this way so I can spend more time with my family. When the cost savings available through Actuary On Call are considered, it questionable whether spending substantially more just to shake hands with an on-site person is really worth it.
